PSYCH 1 Lecture Notes - Lecture 21: East Los Angeles College, Postcentral Gyrus, Occipital Lobe
Document Summary
Aphasia loss of ability to speak. Broca"s aphasia (damage to front of brain) and wernicke"s aphasia (damage to back of brain) were associated with damage to different areas of brain. Brain lesions (destruction of specific brain structires) Brain stimulation studies (electrically stimulate brain directly) Microelectrodes record electrical activity of nerve cells. Different lobes control different functions (gauge"s accident) Corpus callosum-connects two hemispheres (large bundle of axons) Occipital lobe processes visual information from eyes. Broca"s area: ability to converse (speech production; leborgne) Stores memories, experiences of strong emotions, smells, etc. Parietal lobe: receives sensory information for perception. Frontal part is primary somatosensory cortex (first cortical relay receiving information on touch from thalamus) Frontal lobe: location of conscious thinking and emotions. Prefrontal cortex: rational activity, attention, keeping ideas in mind, developing and acting on plans, interpreting social cues. Primary motor cortex (back part): generates motor commands responsible in voluntary movement. Pituitary gland: most hormones secreted by this gland control other endocrine glands.
