Level 3 Unit 2 Part 51: Emotion and motivation

Emotional functions involve many cortical and subcortical brain structures, particularly what are called the limbic areas. Limbic structures have been variably defined, but usually include: the cingulate cortex; part of the basal ganglia called the accumbens nucleus; the hippocampus; a nucleus in the medial temporal lobe called the amygdala; and the hypothalamus. Emotional functions also involve the autonomic and endocrine (hormonal) systems via the hypothalamus and multiple brainstem nuclei.

Abulia refers to a deficit of motivation. Motivation involves autonomic, emotional, and cognitive functions of the brain. Motivation is related to internal drives, such as hunger, or external rewards, such as money. Limbic structures and many other areas of the brain play a role in motivation. Abulia may be seen with dysfunction of many of these areas, but in particular anterior parts of the cingulate cortex.
