PS267 Lecture Notes - Lecture 11: Posterior Parietal Cortex, Superior Colliculus, Temporal Lobe
Document Summary
Lecture 11 attention part 1: the anatomy of attention, the neuropsychology of attention, models of attention, neural mechanisms of attention, attentional control networks. The anatomy of attention: selective attention = the ability to prioritize and attend to some things while ignoring others, properties of attention: We can choose the focus of attention. Attention is limited: multiple brain regions involved in attention: Cortical structures: portions of frontal cortex, posterior parietal cortex, posterior superior temporal cortex, anterior temporal cortex, insula (mid- brain structure) The neurophysiology of attention: much of what we know about attention comes from studying patients with brain damage. Only brush right side of hair, only eat off right side of plate. Example at: www. youtube. com/watch?v=4odhsq46vtu: can grab objects with one hand only, can grab object easily when it is in motion, lost focus and saw only blackboard behind, neuropsychological tests of neglect: Line cancellation test: forgot/missed/neglected some on left side of page.
