These are the brain chemicals that connect the brain and the body. They transmit signals between nerve cells, called 'neurons'. They can also effect sleep, mood, weight, concentration and can cause adverse symptoms when they are out of balance. These are of two types: Inhibitory and Excitatory. Acetylcholine, Glutamine, and GABA are some of these neurotransmitters. • Synapse formation and neurotransmitter receptors • Intracellular trafficking and protein dynamics • Synaptic plasticity and memory • Neuronal circuits in the healthy and diseased brain • Molecular mechanisms of neuropsychiatric disorders
