Glutamatergic Modulation of the Pedunculopontine Nucleus and its

... Abstract: The Pedunculopontine Nucleus (PPN) is the cholinergic arm of the Reticular Activating System and is involved in cortical arousal. More specifically, the PPN is active during waking and REM sleep. The PPN receives input from many areas of the brain, including glutamatergic input from other ...

Neurotransmitter

Neurotransmitters are endogenous chemicals that enable neurotransmission. They transmit signals across a chemical synapse, such as in a neuromuscular junction, from one neuron (nerve cell) to another ""target"" neuron, muscle cell, or gland cell. Neurotransmitters are released from synaptic vesicles in synapses into the synaptic cleft, where they are received by receptors on other synapses. Many neurotransmitters are synthesized from simple and plentiful precursors such as amino acids, which are readily available from the diet and only require a small number of biosynthetic steps to convert them. Neurotransmitters play a major role in shaping everyday life and functions. Their exact numbers are unknown but more than 100 chemical messengers have been identified.
