Document Summary

Objectives: describe how the structure of the central nervous system influences behaviour. If brain activates for each different activity, it is more of an equipotential organ. Speech they produced makes no sense and has difficulty understanding whats said to them. Language disorders from brain damage and imaging studies of language and other functions tell us that functions are localized in specific brain areas. Imaging and other studies: brain lesions, method is to identify brain structure-fu(cid:374)(cid:272)tio(cid:374) (cid:396)elatio(cid:374)ships i(cid:374)(cid:448)ol(cid:448)ed (cid:862)lesio(cid:374)s,(cid:863) o(cid:396) destruction of specific brain structures. Psychologists study humans with brain damage from trauma, stroke, neurosurgery, and tumours, trying to see how symptoms of functional loss relate to different sites of structural damage. But no two cases of damage and behavioural symptoms are exactly alike: to gain experimental control, psychologists have techniques to make localized brain lesions (called ablations) in various non-human species (e. g. , mice, rats).
