| '''Neurotransmitters''' are chemicals that are used to relay, amplify and modulate signals between [[Neurons - Anatomy & Physiology|neurones]] and cells. They can be classified into two main groups; '''small-molecule transmitters (SMT)''' and '''neuropeptides'''. | | '''Neurotransmitters''' are chemicals that are used to relay, amplify and modulate signals between [[Neurons - Anatomy & Physiology|neurones]] and cells.

− | '''Dopamine''' is involved in motivation as well as love and addiction. It is effectively a 'reward system' for the brain. Dopamine also affects the way in which the basal ganglia of the brain affect our movements and a shortage of dopamine can result in diseases such as Parkinson's. Dopamine is the primary neuroendocrine regulator of [[Lactation - Endocrine Control - Anatomy & Physiology|'''prolactin''']] from the anterior [[Pituitary Gland - Anatomy & Physiology|pituitary gland]]. Dopamine produced by the [[hypothalamus]] is secreted via the hypothalamo-hypophysal blood vessels which supply the pituitary gland. Secretion of prolactin via lactotrope cells within the pituitary is inhibited by dopamine. | + | '''Dopamine''' is involved in motivation as well as love and addiction.

| '''Serotonin''' is involved in emotions, mood, sexuality, consciousness, sleep and thermoregulation. Serotonin is utilised by the central nervous system and the gastro-intestinal system. Serotonin has also been linked to mechanisms controlling pulmonary and cerebral vascular vasoconstriction. | | '''Serotonin''' is involved in emotions, mood, sexuality, consciousness, sleep and thermoregulation.
