Abstract

After having stressed the distinction between general adaptive systems andspecific functional systems, the author argues that emotions constitute a general adaptive system distinct from, but interacting with, the cognitive system, considered as the other (more evolved) adaptive system. The main characteristics of the emotional system are its componential nature and its hierarchical organization. These basic features of the emotional system, as well as the brain structures subserving the different components of emotions must, therefore, be taken into account in the neuropsychological study ofemotional disorders. The main components of emotions considered in this educational review are: the evaluation of emotional situations; the emotionalresponse with its expressive-motor and autonomic components and the inhibition of socially unacceptable spontaneous emotional responses. The main levels identified in the hierarchical structure of emotions are: a level of automatic, spontaneous functioning and a level of conceptual processing of emotional information and of controlled selection of the most appropriate response. The brain structures identified as critically involved in these different components and levels of emotions are: the amygdala, considered as the structure where the external stimuli are appraised in terms of their emotional significance; the insular cortex and the hypothalamus, crucially involved in the generation of the autonomic components of emotions; the ventralstriatum, which subserves the execution of stereotyped emotional action patterns and the ventro-medial frontal cortex, playing a critical role in functions of control and inhibition of socially unacceptable emotional responses. The different emotional involvement of the right and left hemispheres in different aspects and levels of emotional processing is also shortly discussed and the quality of emotional disturbances resulting from injury to these brain structures is briefly considered.
