What does reuptake mean in psychology?

n. the process by which neurotransmitter molecules that have been released at a synapse are reabsorbed by the presynaptic neuron that released them.

What is the difference between uptake and reuptake?

Basically, uptake is when the receiver gets it while reuptake is when the sender sucks it back in.

What are autoreceptors examples?

The dopamine D2 receptor, norepinephrine alpha 2a and alpha 2c adrenoreceptors, acetylcholine M2 and M4 muscarinic receptors, and histamine H3 receptors are examples of common autoreceptors expressed in the nervous system.

What is autoreceptor and heteroreceptor?

Heteroreceptors respond to neurotransmitters, neuromodulators, or neurohormones released from adjacent neurons or cells; they are opposite to autoreceptors, which are sensitive only to neurotransmitters or hormones released by the cell in whose wall they are embedded.

What is an example of reuptake?

Reuptake: The reabsorption of a secreted substance by the cell that originally produced and secreted it. The process of reuptake, for example, affects serotonin. Serotonin is a neurotransmitter (a chemical messenger). It is produced by nerve cells in the brain and is used by nerves to communicate with one another.

What is reuptake process?

Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse.

What happens in reuptake?

Reuptake is what happens after a signal is transmitted: The neurotransmitter, its “work” completed, is reabsorbed back into the cell that previously released it.

What is autoreceptors function?

An autoreceptor is a receptor located on the neuron (terminals, soma, and/or dendrites), and the function is to bind a specific ligand (such as neurotransmitters or hormones) released by that same neuron. The autorecptor is mainly used as a feedback mechanism to monitor neurotransmitter synthesis and/or release.

What does the reuptake do?

What do autoreceptors detect?

Autoreceptors on the presynaptic neuron will also detect this neurotransmitter and often function to control internal cell processes, typically inhibiting further release or synthesis of the neurotransmitter. Thus, release of neurotransmitter is regulated by negative feedback.

What causes reuptake?

What happens to neurotransmitters after reuptake?

4. Reuptake: the whole neurotransmitter molecule is taken back into the axon terminal that released it. This is a common way the action of norepinephrine, dopamine and serotonin is stopped…these neurotransmitters are removed from the synaptic cleft so they cannot bind to receptors.
