The most common antidepressants prescribed today come under a class of neuroactive drugs called 'selective serotonin reuptake inhibitors', or SSRIs for short. These include: Citalopram (Celexa), Fluoxetine (Prozac), Fluvoxamine (Luvox), Paroxetine (Paxil), Sertraline (Zoloft) and Venlafaxine (Effexor). The primary mechanism of action for SSRIs to modify the way serotonin gets taken back up at the synapse. Not all SSRIs work on boosting serotonin levels though. Some like Venlafaxine also increase the amount of noradrenaline available… Read More
Yes. I am one of them. My name is Jessamine and I have a spinocerebellar atrophy.
The reason why Sensory neurons are called as afferent neurons is: _ Afferent Neurons mean the neurons carries the nerve impulse toward the brain (CNS) or the spinal cord (PNS). _ Sensory which always begins from the outside spaces, or peripheral places outside from CNS or PNS, need to be carried to CNS or PNS to analyze. That's the reason why they called sensory neurons as afferent neurons which bring sensor toward the brain or… Read More
No. When you are born, you have the most neurons you will ever have. Until you are in your early 20's your brain continues to "trim" neurons from your brain, a mechanism that aids in learning and development. After this point, as you age, you begin to lose neurons, simply from age. After brain development is complete in utero, there are only two locations in the brain that are capable of generating new neurons: the… Read More
Feelings of "unreality" are often called "derealization," "depersonalization," or "dissociation." This can be caused by a number of things, including depression, PTSD, anxiety, etc. A mental health professional can help determine the contributing factors and appropriate treatment. It can be helped. Although the list above are simply a list of "symptoms" inlcuding ncluding depression, PTSD, anxiety, etc., please keep in mind all that symptoms have a "cause" one cause that must be investigated and ruled… Read More

It depends on what level you wish to contribute to the field. For instance, with a 3-4 year Bachelor degree you could enter as a technician or lab assistant. Or, if you wanted more control over the experiments you could earn yourself a doctorate, which normally takes at least 3 years to do over and above Bachelors (so 7-8 years), or Bachelors + Masters (8-9 years).
Morphine (and other opioids) bind to enkephalin and endorphin receptors, activating (agonizing) them to result in a net inhibition of nociception (pain sensation). These receptors also increase activity in the mesolimbic brain, which is responsible for inducing pleasure states and creating habit-forming and addictive behavior. Norepinephrine and epinephrine "signals" are downmodulated so that pulse, blood pressure, and anxiety are reduced.
Iodine (a halogen) forms a starch-iodine complex by binding with amylose coils, which results in a transfer of charge between amylose and iodine, changing the energy levels of iodine atoms, and producing a dark blue color.
Mathematics is used daily in the field of medicine. Math is used to write prescriptions and administer medication. It is also used to draw up statistical graphs of epidemics or success rates of treatments.

Selective serotonin reuptake inhibitors (SSRIs) achieve their therapeutic effect by modifying synaptic availability of the neurotransmitter serotinin. This is accomplished, first of all, by blocking the proteins that normally transport serotonin back into the cells that release them (presynaptic cell). In doing so, synaptic levels of serotonin are temporarily boosted. This phase is normally associated with an acute increase in anxiety. However, this subsides over several days as subtypes of postsynaptic 5-HT receptors down-regulate in… Read More
The SSRIs can be both CYP450 enzyme inhibitors AND inducers. Inhibitors inhibit the metabolism of drugs, causing the body to have increased levels of that drug. Inducers speed of the metabolism of a drug, causing the body to inactivate/eliminate to a further extent than it normally would. It depends on which SSRI you are talking about. They all have actions on various isoforms of CYP450, but the SSRIs which cause the greatest problems with inhibition/inducing… Read More

Acute alcohol intoxication is result of widespread changes in brain metabolism. The greater the amount of alcohol the greater the affect on your brain. One of the mechanisms by which alcohol lowers brain metabolism is via its interaction with GABA receptors. GABA receptors are an inhibitory class of receptors whose function is to reduce the activity of neurons. Many drugs used in the treatment of anxiety also work by this mechanism. Because GABA receptors are… Read More

The solubility of oxides and other ceramic powders depends on what the solution and solvent should be. Temperature is also important. For example one definition of glass says that it is solid solution of natrium oxide, kalium oxide and silicium oxide. many kinds of steel are similarly defined as "interstitial solid solution of carbon in alpha-iron", etc. As for the solubility of metal oxides in water, it is close to zero. The same for alcohols… Read More
The clearance of alcohol from the body is not affected by citalopram. SSRIs like citalopram work on serotonin- and norepinephrine- synthesizing neurons and slowly cause an increase in the synaptic availability of both of these neurotransmitters. The role of serotonin in the brain is modulatory, i.e., it facilitates the release of other neurotransmitters in cerebral cortex; whereas alcohol is a CNS depressant. It binds to and and opens GABA-gated channels enhancing inhibitory synaptic transmission. Alcohol… Read More
Tricyclics are more potent antidepressants compared to the newer SSRIs. The reason SSRIs tend to be prescribed more, however, is because tricyclics are less well tolerated due to their antimuscarinic effects, such as: dryness of mouth, constipation, dizziness, abnormal heart rhythm, blurred vision and urinary retention. Trycyclics cannot be given to people with with hypotension or heart problems. SSRIs generally have a longer half life (15-50 hrs vs. 12-32 hrs for trycyclics) and do not… Read More
Depends on your qualification, experience and the job you are applying for.
One of the defining properties of a neurotransmitter is that is must be synthesized in the neuron. The brain does not synthesize methamphetamine. Methamphetamine is introduced exogenously and exerts its effects on a neurotranmitter system called the 'adrenergic system'. Methamphetamine also has a direct effect on dopamine transmission. The drug, like its parent structure (amphetamine) causes a release of dopamine through reuptake transporters (DATs), which have been modulated to reverse their normal function as a… Read More

Tricyclics, e.g. Amitriptyline and impramine, were compounds that were introduced in the 1960s to treat depression by helping boost synaptic levels of serotonin and noradrenalin. They were called 'tricyclics' because their structure contains three amine rings joined together. Tricyclics are not commonly prescribed today and have been superseded by the newer and safer 'selective serotonin reuptake inhibitors' or 'SSRIs' for short. Tricyclics are more effective in treating serious depression than SSRIs, however; so their main… Read More
nothing it is perfectly safe ANSWER Cannabis is not "perfectly" safe, nor is is certainly dangerous. No one is completely certain of its full effects the chemical function of the brain is not fully elucidated, nor are the complete effects of cannabis on this complex system. What is known is that the active ingredient, THC, effects cannabinoid mediated neurotransmission in the brain on binding to CB1 receptors. Binding to these receptors causes a reduction in… Read More
Curare does NOT create an action potential. It binds to nicotinic acetylcholine receptors (which are primarily excitatory), and prevents the formation of an action potential.
Inhibitory neurotransmitters prevent the firing of neurons by binding with certain receptors, causing the influx of chloride ions to hyperpolarize the neuron. When this happens, it requires a much larger excitatory signal to override the inhibitory effects in order to allow the neuron to fire.
Lumbosacral neuritis is characterized by the nerves in the lumbar area of the spine being inflamed. Pain in the lower back and pain shooting down the legs are both common symptoms.
In behavioral neuropharmacology, this refers to a shift in the 'pursuit of pleasure.' Stimulation of cannabinoid receptors, for example, can cause a hedonic shift in food consumption.
An example of photoshynthesis is in plants, which are the only organism that can do this system. It's a way for them to get food by the sunlight, which they take in and convert into energy for them.
Enzyme-activity studies on acetylcholinesterase (AChE), the enzyme that is responsible for hydrolyzing acetylcholine (ACh), in the presence of opioids date back to the 1940s. AChE inhibition by opioids has been suggested to be partly competitive and partly non-competitive(1, 2). Competitive inhibition would imply that that opiods compete with ACh for AChE, while non-competitive inhibition could mean that opioids bind to non-ACh binding regions on AChE and inactivate the part that hydrolyzes ACh. Because AChE can… Read More
Amphetamine and methamphetamine (the latter being more potent) cause the release of dopamine, serotonin and noradrenaline from axon terminals. Since the parts of the brain that contain the richest density of these cells are also involved in mood, perception, cognition and to a lesser extent, movement - this explains the cognitive and behavioral changes that occur following abuse of this class of drug.
Curare is a competitive inhibitor of acetylcholine. It fights with acetycholine for postsynaptic receptors.
In severe cases of anxiety and panic disorders, benzodiazepines such as alprazolam, clonazepam and lorazepam are effective - but their long term use is limited by the way the brain habituates to them (which means higher doses are necessary to achieve the same therapeutic effect). So they are more commonly prescribed for the short-term relief of mild anxiety, where the underlying cause may be treatable through other means (behaviorally, and perhaps with a newer generation… Read More
No it is not a trycyclic. Alprazolam is a benzodiazepine
It doesn't, it causes the opposite: a depolarisation block, which is why is used as a muscle relaxant in some circumstances. It may be that your recording electrodes were near a cell where curare had not yet diffused to. Or it may be related to disinhibition from blocking interneurons that express nicotinic accetylcholine receptors.
Ethanol (ethyl alcohol) affects many areas of the brain. However, the most pronounced impact is found in the cerebrum, hippocampus, and cerebellum. Ethanol affects the GABA (gamma-aminobutyric acid) neurotransmitter system, binding to GABA-A and GABA-B receptors, and increasing their ability to hyperpolarize neuronal cell membranes. So, it inhibits (slows, reduces) brain activity. When this happens in the cerebral cortex, higher thought is slowed or inhibited. In the hippocampus (where a large number of GABA receptors… Read More
Sensory, motor and interneuron.
Tricyclic antidepressants typically bind to serotonin (and, in some cases, norepinephrine) transporters to inhibit reuptake back into presynaptic neurons, which results in the net increase in levels of monoamine (serotonin and norepinephrine) in the synapse. This synaptic increase allows for more serotonin (and/or norepinephrine) to bind/rebind with postsynaptic serotonin (or norepinephrine) receptors, which upmodulates the serotonin (or norepinephrine) signal.
Postsynaptic acetylcholine receptors at neuromuscular junctions
DNA...which comprises genetic information. When transcribed and translated, it forms many different genes. One or more genes code for a given trait.

No. Bupropion (aka Wellbutrin) is known as an atypical antidepressant in that it prevents the reuptake of serotonin, norepinephrine, and dopamine (to a lesser extent). Typical tricyclic antidepressants only block reuptake of serotonin and norepinephrine. It's unique dopamine reuptake inhibition capability allows it to be used to treat nicotine addiction (marketed as Zyban) and, to some extent, attention deficit disorder. Furthermore, it lacks the classic three ring chemical structure of tricyclic antidepressants (TCAs). Here are… Read More
Drugs that are agonists for the GABA receptor (such as benzodiazepines) are better treatment options for different forms of spasticity, rather than GABA itself.
the 6th sense is a scary movie. Emily Osment's older brother is in that movie, but it was when he was a little kid. the movie is about a little boy and his mother having a 6th sense, which is being able to see dead people.
The action potential is an all-or-none phenomenon.
Curare binds to and inhibits (blocks) nicotinic acetylcholine receptors. By doing this, it prevents acetylcholine from binding to and activating those same receptors. This prevents the excitatory "signal" from forming, and prevents the action potential from forming.
If you mean the big spill that just happened, It happened in the gulf of Mexico and started when a BP oil rig caught on fire and sunk into the ocean, which is now spilling oil miles below the sea under water. Gee, thanks BP. Hope this helped!
It typically takes the brain about 1 month to get past acute withdrawal symptoms, and possibly another 2 or 3 months to completely readjust receptor densities. This varies from person to person, due to genetic factors, predispositions to other neurological disorders/states, and their dosage on the drug.
Foods high in: - L-tyrosine and L-phenylalanine (amino acids precursors for dopamine and norepinephrine) - fish, cheese, soy, nuts, meats - L-tryptophan (amino acid precursor to serotonin) - milk, turkey, chicken - choline and lecithin (precursors to acetylcholine) - fish, soy - omega-3 fatty acids - fish oil, seed oils (such as flaxseed oil) - vitamin B6 and B12
Depletion of resources is due to the reckless use. Man uses more than he needs the resources.
It binds to GABA receptors, hyperpolarizing the neuronal membrane, inhibiting neurotransmission...primarily in the hippocampus, cerebellum, and cerebral cortex.
No. While the underlying mechanisms of long-term memory storage are not well understood, the general consensus is that memory recall does change every time you remember something.
A peristaltic contraction is controlled by the autonomic nervous system and is the contraction of smooth muscle in the digestive system to create a wave-like motion, allowing food and digested materials to be transported through the digestive system. This process is called peristalsis. It is mostly controlled by the neurotransmitter acetylcholine.
mechanism of neurohumoral transmission
Curare acts by competitive inhibition at the nicotinic acetylcholine receptor.
It doesn't. I prevents an action potential from forming.
Clozapine is not a tricyclic antidepressant, but rather an atypical antipsychotic medication. Atypical antipsychotics differ from typical antipsychotics by the range of receptors that are modulated or affected. Typical antipsychotics primarily inhibit Dopamine 2 (DA2) receptors. Atypical antipsychotics block a host of receptors, namely serotonin and dopamine, but also including alpha and histamine receptors in varying proportions. The benefit of Clozapine is that there is a lesser degree of dopamine inhibition that is aimed at… Read More

Tricyclic antidepressants are available only with a physician's prescription and are sold in tablet, capsule, liquid, and injectable forms
In pharmacokinetics, it represents: - Absorption - substance enters blood circulation - Distribution - substance is carried through the fluids and tissues of the body - Metabolism - substance is chemically processed/transformed into one or more other substances (called metabolites) - Excretion - substance, and/or its metabolites is removed from the body (or accumulates in tissues)
It is an Antipsychotic medication
Some commonly used tricyclic antidepressants are amitriptyline (Elavil), desipramine (Norpramin), imipramine (Tofranil), nortriptyline (Pamelor), and protriptyline (Vivactil).
By having fun! Massage, hugging, kissing, holding hands, controlled sex (like tantra), hanging with friends, cuddling, eye gazing, etc. A good book for reference is The Chemistry of Connection.
Prozac (fluoxetine) is an SSRI (selective serotonin reuptake inhibitor). It targets reuptake channels for the neurotransmitter serotonin, preventing serotonin from reentering the presynaptic neurons to be removed from the synaptic cleft, thus forcing an accumulation of serotonin and repeated triggering of the serotonin "signal" in the postsynaptic neurons.
Yes, many of the structures involved in memory and mood regulation are found in both sides of the brain. A cyst can impair their function and change the way a person acts
Curare is an example of a non-depolarizing muscle relaxant that blocks the nicotinic acetylcholine receptor (nAChR), one of the two types of acetylcholine (ACh) receptors. The main toxin of curare, d-tubocurarine, occupies the same position on the receptor as ACh with an equal or greater affinity, and elicits no response, making it a competitive antagonist.
The terms antagonist/agonist only apply to 'exogenous' compounds, namely drugs and toxins, and not neurotransmitters - which are commonly classed according to whether they are excitatory or inhibitory. Examples of a the latter include GABA and glycine.
Tricyclic are a family of antidepressants that were given to people before the SSRI. Often psychiatrists prescribe a tricyclic and a newer anti-depressant usually a selective serotonin Inhibitor or a serotonin Norefenefphan selective inhibitor. Your doctor can usual decide what is safe

Soy lecithin is not, itself, a phytoestrogen. However, soy does contain phytoestrogen compounds.
It blocks the receptors for acetylcholine, so the nerve cells cannot receive the signal to generate an action potential.
Amphotericin B. We can combine this Amphotericin B with Flucystosine or Fluconazole to get a synergistic effect.
