NSE 12A/B Lecture Notes - Lecture 6: Sensory Deprivation, Amblyopia, Cerebral Cortex
Document Summary
Readings (p&p p 259, 1301-1323; a&b p 117-123, 333-344, 368-370) Differentiate among the three components of any sensory experience: reception: stimulation of a receptor nerve cell (designed for one type of stimulus such as light, touch, sound). For special senses, the receptors are grouped close together or located in specialized organs such as the taste buds or the retina. Perception takes place when the person becomes conscious of the stimuli and receives information. It includes integration and interpretation of the stimuli on the basis of the person"s experiences. Describe common causes and effects of sensory alterations: sensory deficits: loss in normal function of sensory reception and perception. Occurs with age, (children) amblyopia (lazy eye), retinopathy of prematurity, congenital causes of diseases such as cataract and glaucoma; (adults) amd, diabetic retinopathy, cataract, glaucoma. It affects the sense of self since the person might be withdraw by avoiding communication or socialization with others in an attempt to cope with the sensory loss.
