What is the action of dopamine on the postsynaptic membrane?
All neurotransmitters have an effect on the post synaptic membrane of either inhibition or excitation. Dopamine is an Excitatory NT so if a Excitatory Neuron meets with another Excitatory Neuron it creates Excitation. However if it meets with an Inhibitory Neuron Dopamine and the other Excitatory NT's wll only create Inhibition. Only GABA and Glycine are considered Inhhibitory NTransmitters.
What are neurotransmitters for postsynaptic neuron?
Neurotransmitters are chemical messengers that transmit signals and information from the presynaptic neuron to the postsynaptic neuron at the synapse. They bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential and triggering a new signal to be passed along the neural pathway. Some common neurotransmitters include acetylcholine, dopamine, serotonin, and glutamate.
What are dopamine-sensitive neuron?
Dopamine-sensitive neurons are a type of neuron that responds to the neurotransmitter dopamine, which plays a crucial role in regulating mood, motivation, reward, and motor control. These neurons are primarily found in specific areas of the brain, such as the substantia nigra and the ventral tegmental area. They are involved in various neurological and psychiatric conditions, including Parkinson's disease and schizophrenia, making them a key focus of research in understanding the brain's reward systems and related disorders.
This contains neurotransmitters that allow a signal to cross from one neuron to another?
A synaspe.. something like that lol
What chemical class of neurotrasmitters includes the catecholamines dopamine and norepinephrine?
Neurotransmitters are the chemicals that transmit neuron signals. Its three classifications are: the amino acids, peptides, and the monoamines and other biogenic amines.
What are the transmitting chemicals of a neuron?
Dopamine and Acetyl Cholines

What happens when a substance gets into a neuron?
When a substance enters a neuron, it can bind to receptor sites on the neuron's membrane, triggering a cascade of events within the neuron. This can lead to changes in the neuron's electrical activity, release of neurotransmitters, or alterations in gene expression, ultimately affecting the neuron's function.
What parts of brain do the neurolyptics effect?
The theory behind why individuals develop 'psychotic' symptoms is based upon the idea that there are elevated levels of dopamine in the brain. Dopamine is a neurotransmitter, a molecule that passes messages between neurons. For example, when a nerve impulse arrives at a dopaminergic neuron (also known as a pre-synaptic neuron), dopamine is released from the cell and diffuses through a space between two neurons, called the synaptic cleft. Dopamine then binds to specific dopamine receptors on a different neuron (post-synaptic neuron) producing a specific signal, impulse or effect. Dopamine is then released from its receptors and 're-absorbed' into the pre-synaptic neuron, or degraded by enzymes in the synaptic cleft. The neuroleptics block dopamine receptors thereby inhibiting the ability of dopamine to attach to these receptors and generate signals. However, unlike the typical neuroleptics, the atypicals merely transiently block the receptors therefore allowing some dopamine to bind to the receptors and generate signals. The atypical neuroleptics are also able to block serotonin receptors located on dopaminergic neurons. When serotonin binds to these receptors it inhibits dopamine release. However as these receptors are blocked by atypical neuroleptics, the dopamine secretion is increased. The transient rather than permanent blocking of dopamine receptors and the blocking of serotonin receptors and subsequent increases in dopamine, it is for these reasons that the atypicals are thought to produce fewer adverse effects than the typical neuroleptics. However, the atypical drugs differ in their 'stickyess' when binding to dopamine receptors and also in the ratio of which dopamine ad serotonin receptors are affected. This may result in some atypicals producing higher levels of specific adverse effects than others. The atypicals may also bind to other receptor types, producing further adverse effects (see side effects of atypicals section).

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.
A molecule that is released from synaptic vesicles and serves as the means of communication from one neuron to the next or from one neuron to an effector cell?
a neurotransmitter such as acetylcholine, or dopamine. Even a neuropeptide.They will cause a receptor gated channel to open post synaptically
What chemicals are used to transmit impulses through the neurons?
the transmission of a nerve impulse along a neuron from one end to the other occurs as a result of chemical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized that is there is a difference in electrical.
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
How do neurotransmitters differ from neuromodulators?
is a substance that is produced by a neuron that is other than a neurotransmitter and is used to transmit information to other neurons to regulate their activities. examples are dopamine, s.erotonin or histamine
What neuron makes you jump for joy?
The neuron that plays a key role in feelings of joy and pleasure is the dopaminergic neuron, particularly those in the mesolimbic pathway. These neurons release dopamine, a neurotransmitter associated with reward and motivation, which can lead to feelings of happiness and euphoria. When we experience something joyful, such as achieving a goal or receiving good news, these neurons activate, contributing to the physical reaction of jumping for joy.
