Neurotransmitters are chemical messengers that help nerve cells (neurons) communicate with one another. These chemical messengers affect the brain by either exciting (stimulating), inhibiting ...

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 ...

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.

Neurobiologists have made a breakthrough in understanding how environmental factors might contribute to autism spectrum ...

A healthy brain balances “activate” and “inhibit” signaling in its neural microcircuitry, with the inhibitory signaling often provided by cell receptors for the neurotransmitter GABA.   Unexpected ...
