dopamine receptors

dopamine receptors

Nerve cell membrane binding sites that are activated by dopamine molecules. Some are excitatory and some inhibitory, but both classes contain many subtypes. Some of these receptors mediate behavioural effects.

The possibility does exist that prehistoric ancestral species over two million years ago carried the low dopamine brain function due to low dopamine receptors (Blum et al.
The results showed that a small subset of dopamine neurons actively regulate the acquisition of memories and the forgetting of these memories after learning, using a pair of dopamine receptors in the brain.
As a Parkinson's disease treatment, says UCB, the mechanism of action of Neupro is thought to be related to its ability to stimulate dopamine receptors within the region of the brain that regulates movement.

Cocaine blocks the reuptake of dopamine, and after chronic abuse it causes a reduction in the number of postsynaptic dopamine receptors and eventually leads to damage of dopamine-responsive cells in the brain, said Dr.
