Neurotransmitters are chemical messengers very important in the conveyance of signals across synapses in the nervous system. Neurotransmitters can be regarded as a form of communication between neurons that may influence various aspects of physiological and psychological processes. Neurotransmitters constitute a basic neuroscience understanding with insights into mental health problems.

Serotonin is another major neurotransmitter which controls moods, sleep, and appetite. It has been linked to depression and anxiety disorders. Another important neurotransmitter includes dopamine, the neurotransmitter for reward, motivation, and motor control. Dopamine dysregulation has been associated with Parkinson’s disease and schizophrenia.

Norepinephrine or noradrenaline is implicated in mediation of attention, arousal and stress. It is important for the body’s “fight or flight” response and appears to be involved in mood as well. Acetylcholine is also involved in some muscular activity and in cognitive processes involving learning and memory. Impairment of acetylcholine has been implicated in Alzheimer’s.

GABA and glutamate are among the two major inhibitory and excitatory neurotransmitters, respectively, thus playing a huge role in neuron excitability regulation. Their imbalances, such as being in an inhibitory-dominant state over the excitatory, may lead to conditions such as epilepsy and anxiety.
