For this communication to occur, the presynaptic neuron releases a neurotransmitter, which is then received by a postsynaptic ...

There are two types of removal: Re-uptake – the neurotransmitter is reabsorbed back into the presynaptic neuron and restored inside a vesicle ready to be used again. For example, noradrenaline.

Methylphenidate is thought to block the reuptake of norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extraneuronal space. Swallow whole.

University of Texas Southwestern researchers showed that knockout mice missing RIM1α, a presynaptic protein previously studied in vitro, performed worse at learning and memory tasks than did two other ...
