Biological explanations and treatments
|•||Basic neuro-anatomy as it relates to mental health disorders|
|•||The neurotransmitter systems and the key neurotransmitters that influence mood and behaviour|
|•||The drug treatments that are used to alter neurotransmitter levels and, hence, mood and behaviour|
|•||Three physical interventions used to treat mental health problems: transcranial magnetic stimulation (TMS), electroconvulsive therapy (ECT) and psychosurgery.|
The brain is an intricately patterned complex of nerve cell bodies. It is divided into four anatomical areas: the hindbrain, midbrain, forebrain and cerebrum.
The hindbrain contains the parts of the brain necessary for life: the medulla oblongata, which controls respiration, blood pressure and heart beat, the reticular formation, which controls wakefulness and alertness, and the pons and cerebellum, which correlate muscular and positional information.
Above these lies the midbrain, which also contains part of the reticular system and both sensory and motor correlation centres which integrate reflex and automatic
