PSYC1020 Lecture Notes - Lecture 13: Neuropsychological Test, Phineas Gage, Central Sulcus
Document Summary
Frontal lobe: anterior to central sulcus, cognitive control of behaviour, executive functions, reasoning, planning, problem solving. Inhibitory control: working memory, emotion, motor functions, premotor cortex - motor planning, primary motor cortex - execution, speech (broca"s area) Parietal lobe: posterior to central sulcus, attention, directing attention to explore visual world, spatial neglect, spatial awareness, linking vision to action, represents spatial location of objects around us for guiding actions, primary somatosensory cortex, perception of touch, pain. Parietal and prefrontal network for attention: corbetts and schulman (2002, network of prefrontal and parietal cortex mediate attention, different areas for goal directed and stimulus driven attention, based on brain imaging studies and patients with brain legions. Lesion to parietal cortex: deficit in directing attention to one side of space, not due to any sensory deficit (normal vision) Executive and inhibitory control: crucial for control of behaviour, selection of appropriate actions.
