Document Summary
Chapter 2 biological foundations of sensory perception. Lesion studies animals for behavioural analysis. Study of clinical cases in humans who suffered some form of brain damage: flourens able to disrupt certain motor functions but unable to find deficits in more elaborate forms of behaviour. Visual perceptioin: some functions where only one hemisphere dominates, broad distribution of mental functions across two hemispheres means localized injury will not affect the other side, two hemispheres left larger specialized for handedness along with speech. Emotional behaviour: parietal lobe along the top middle. Processing of spatial relationships: frontal lobe front (behind the forehead) Judgments about future activities: dissected cerebrum = white and grey. White matter most of interior: composed of fibres that interconnect various brain areas. Extensive connections with the cortex + composed of anatomically distinct nuclei with different functions in transmission of sensory and motor information to and from cortex. Visual auditory and touch signals travel through thalamus on way to cortex.
