Document Summary
Auditory cortex plays a role in discriminating 2 forms of auditory processing: actually present, rapidly presented stimuli, complex patterns of stimuli. Zatorre: key difference: left hemisphere concerned with speed and right with distinguishing frequency differences (a process called spectral sensitivity: amusia: about 4% of people have a condition known as congenital amusia - tone deafness - amusic. Disorders of visual perception: patients with temporal lobe damage are impaired at object recognition, complex pattern recognition, right temporal lobe lesions lead to abnormal face perception and biological motion recognition. Stimuli can be interpreted in different ways depending on the context. Example: fall - the season or a tumble. Amnesia for events after bilateral removal of the medial temporal lobes. Conscious recall of information: left temporal lobe. Impaired recall of verbal material: right temporal lobe lesions= Affect and personality: stimulation of anterior and medial temporal cortex produces feelings of fear, temporal lobe personality. Personality that overemphasizes trivial and petty details of life.
