Motion sickness is a very common condition that affects about one in three people, but the brain circuits involved are ...

The ultimate effect of a signal from one neuron on the next neuron depends on the function of the synapse, which is based on the type of neurotransmitter released. Excitatory synapses send signals ...

"Amphetamines belong to a class of drugs called sympathomimetic amines or stimulants that cause the release of excitatory neurotransmitters, such as dopamine, to stimulate thecentral nervous ...

Researchers hope their findings on motion sickness could also lead to improved medications for people with this condition.

However, a series of weak stimuli can combine, increasing the amount of neurotransmitter that is released. This results in enough neurotransmitter being diffused across the synaptic cleft to ...

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.
