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 ...

The team found that motion activates glutamatergic neurons – neurons that produce glutamate, the primary excitatory neurotransmitter in the central nervous system – in the medial vestibular nucleus ...

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.
