Neurotransmitters are chemical messengers that have excitatory, inhibitory, and modulatory actions. Learn what they are and ...

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.

Loss of memory and reduced cognitive functions are some of the effects that can persist for years. Neurobiologists at the ...

Have you ever noticed how your food choices can impact your mood? From the initial burst of energy after a satisfying meal to ...

A fluorescent probe designed to incorporate a fluorophore into the structure of a neurotransmitter finds activity-dependent heterogeneity in dopamine release at individual synapses ...

The modulatory neurotransmitters activate G protein-coupled receptors, which share signal transduction systems in cells. In addition to regulating key physiological functions, these systems are ...

As such, the locus coeruleus is the principal site for brain synthesis of noradrenaline, a neurotransmitter. Noradrenaline is contained in small round compartments, called vesicles, inside the ...

Current antidepressants act on neurotransmitter systems by affecting three distinct processes: (1) neurotransmitter degradation, (2) neurotransmitter reuptake (reabsorption into the releasing cell ...

It’s most likely to occur with drugs that interact with your brain’s neurotransmitters. For example, research has shown that drugs that interfere with the neurotransmitter acetylcholine might ...

The solution, some suggest, lies in deploying female crash test dummies to ensure vehicles are truly safe for women. However, making cars safer for women is complicated, and not everyone agrees ...

Recreational drugs can affect neurotransmitters in the reward pathway within the brain. They can act as either agonists or antagonists. Recreational drugs can also stimulate the release of ...

The effects of sustained drug abuse can manifest in many ways. Loss of memory and reduced cognitive functions are some of the ...
