What are the reaction that having a great time leaping across synapses?
There are no reactions, the end of a nerve produces a gas that goes across the synapses and creates the electrical impulse on the other side of the synapses and continues the message!
How much dopamine does the brain release during physical exertion in extreme sports like whitewater kayaking or skydiving?
well dopamine certainly plays a part in the pleasurable factors associated with exercise and other physical activity, but it is not the main "reward" our brain offers after physical exertion. dopamine is associated with feelings of excitement and anticipation, and even danger for some people, skydiving would induce the release of dopamine into the synapse. there is no specific "quantity" of dopamine that is released, but the number of dopaminergic messengers and available synapses increases dramatically after physical/sexual stimulation or exciting sports. continuous excitation of these chemicals and pathways (by natural means) actually changes the physical makeup of the brain over time to allow more dopamine to be present in and outside of the synapse. sports like running, walking and kayaking have a small effect on dopamine, but the continuous physical exertion (to the point of sweating, and for at least 30 minutes) releases endorphins into your blood, causing a feeling of well being and physical wellness. dopamine=excitement and immediate pleasure, endorphins=balance with some euphoria. WARNING both of these chemicals are easily manipulated by drugs such as cocaine (dopamine active) or heroin and painkillers (endorphin producing). these artificial "highs" change the physical structure of the brain, just as exercise does, but in a very negative way. of course, this is due to prolonged use and abuse. anyway, keep exercising and doing fun things, you'll be sure to stay happy.
Which system involves a synapse?
All nerves have synapses, which are where the nerve junctions are located, so the nervous system involves synapses.
Where are electrical synapses found?
Synapse is located, where two neurons meet each other. One cubic cm of brain cortex have about one billion synapses, probably.
Why do you have synapses?
I do not know nor do i want to
What are dopamine and serotonin?
They are neurotransmitters. They are sent across synapses from one nerve to another.
What are the antagonists to antipsychotics?
any drugs that can increase dopamine concentration at synapses: L-dopaamphetamineany drugs that mimic dopamine action : e.g. bromocriptine
What causes dopamine to be released?
one path is important for movement. another path is important for memory and cognition. Most antipsychotic drugs decreases activity at dopamine synapses. L-dopa, used for Parkinson's disease, increases availability of dopamine
What does the word synaptic mean?
The word synaptic is an adjective which means, pertaining to the synapses. So, I could describe dopamine as a chemical that has a synaptic function, as a neurotransmitter.
What effect does Methamphetamine have on GABA receptors?
Methamphetamine (METH) increases the amount of dopamine released in synapses. Methamphetamine enters the neuron by passing directly through nerve cell membranes. It is carried to the nerve cell terminals by transporter molecules that normally carry dopamine or norepinephrine. In the nerve terminal, methamphetamine enters the dopamine- or norepinephrine-containing vesicles and causes the release of neurotransmitter. Methamphetamine also blocks the dopamine transporter from pumping dopamine back into the transmitting neuron.
What gives you a high?
It depends on which substance is taken, different drugs have different modes of action and different target areas in the brain. Stimulants for example, work on the neurotransmitter Dopamine, either through releasing more Dopamine into the synapses (the small gaps between the ends of each "string" of nerve fiber) or the re-uptake of Dopamine thus increasing the effects of the Dopamine already present in the synapses. Most other drugs work in similar ways but by targeting other neurotransmitters. The drugs have a molecular structure that is very similar but slightly different to that of the neurotransmitter it targets, and because of this it fits on for example the Dopamine receptors (receptors are "keyholes" in which only a specific type of "key" fits to activate it, namely the neurotransmitter it is designed for) in the nerves thus mimicking Dopamine in it's effects. The same goes for most other types of drugs, such as Opioids which target the mu and kappa opioid receptors, most Hallucinogens which target the 5HT serotonin receptors, most Dissociatives which target the NMDA receptors and most Depressants such as Alcohol and tranquilizers which target the GABA-A receptors and it's sub-receptors.

How do anti depressants work?
Antidepressants work by increasing the quantity and action of all or some of the neurotransmitters, namely (1)serotonin, (2)dopamine, (3) norepinephrine at the synapses in brain in a person suffering from depression.
What is the chemical secreted into a gap between neurons at a synapse?
There is not just one chemical secreted into synapses (the gaps between neurons); instead, there are many chemicals secreted from the terminal buttons of neurons into the synapses. They are called "neurotransmitters."
Where does synapses take place?
The synapses take place in the spinal cord
How many synapses does the brain have?
The brain is estimated to have around 100 trillion synapses. These synapses are the connections between neurons that allow them to communicate with each other.
How cocaine effects your brain?
The neurotransmitter dopamine transmits brain signals by flowing from one neuron into the spaces between neurons and attaching to a receptor on another neuron. Normally, dopamine then is recycled back into the transmitting neuron by a transporter molecule on the surface of the neuron. But if cocaine is present, the drug attaches to the transporter and blocks the normal recycling of dopamine, causing an increase of dopamine levels in the spaces between neurons that leads to euphoria. Cocaine, however, attaches to the same transporter binding sites as dopamine. This means that, when cocaine is introduced, dopamine cannot bind to the dopamine transporter and is stranded in the synapses. Thus, cocaine's blocking action leads to an increase of dopamine levels in the synapses that, scientists believe, normally produce feelings of pleasure. Cocaine's action intensifies these feelings into euphoria, studies show. it makes you trip out you start seeing things it makes you loose weight according how does your body take it sometimes it just makes you get inflated (fat) it dialetes your eyes and on the come down you probly make all your body hurt your muscles
