PSYC 150 Lecture Notes - Lecture 4: Cerebral Cortex, Frontal Lobe, Grey Matter
Document Summary
Transfer of information, coordination of activity between hemispheres. Frontal lobes contain motor cortex, broca"s area, frontal association areas. Damage and impairment in ability to produce or use language. The deficit in language production die to brocia"s area damage. Typically able to understand what is being said to them, but unable to fluently speak. May be limites to one or very few words. Acquired language diorders resulting from brain damage. Speech is preserved, but language content is incorrect. May vary from the insertion of a few incorrect or nonexistent words to a profuse outpouring of jargon. Thinking, motivation, future planning, impulse control, emotional responses. Major changes in emotional responses if damaged. Famous case of a man named phineas gage. Touch, pressure, temperature, pain register in cortex. Association areas involved in reception and interpretation of visual information. Wernicke"s area (left lobe) and association areas for interpreting auditory information. Wernicke"s aphasia: speech is fluent but incomprehensible to others.
