Neurochemical Networks Encoding Emotion and Motivation

Neurochemical Networks Encoding Emotion and Motivation

An Evolutionary Perspective

(p.29) 3 Neurochemical Networks Encoding Emotion and Motivation
Who Needs Emotions?


Oxford University Press

This chapter examines the neurochemical networks that encode emotion and motivation from an evolutionary perspective. It provides a framework for thinking about the evolution of brain neurotransmitter systems that mediate motivational processes and emotional expression. It suggests that neurochemical coding appears to be conserved in evolution and it provides several examples with peptides and monoamines to prove this assertion. This chapter also contends that while emotional systems generally serve a highly functional and adaptive role in behaviour, they can be altered in maladaptive ways in the case of addiction.

Keywords:   neurochemical networks, emotion, motivation, brain neurotransmitters, emotional expression, motivational processes
