PSY 1001 1st Edition Lecture 4 Outline of Last Lecture I Nervous System a Central Nervous System b Peripheral Nervous System II Major Divisions of the Brain a Forebrain b Midbrain c Hindbrain Outline of Current Lecture I Major Lobes of the Cortex a Occipital b Parietal c Temporal d Frontal II Examples of Systems a Basal Ganglia b Limbic System c Cerebral Cortex II Some Organizing Principles Current Lecture I Major Lobes of the Cortex a The right side of the brain controls and processes information from the left side of the body b The left side of the brain controls and processes information from the right side of the body c Occipital lobe i Almost exclusively devoted to vision and visual perception These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute ii Lies at the rear of the brain and is specialized for sight iii When sensory information enters the brain it first goes to that sense s primary sensory cortex the to the association cortex d Parietal lobe i Perception of touch spatial perception ii Contains the somatosensory cortex which is sensitive to touch pain and temperature iii Helps track objects located in space iv Communicates information to the motor cortex every time we reach grasp or more our eyes e Temporal i Perception of objects auditory perception hearing language lecture 4 comprehension 1 Damage agnosia not able to recognize common objects comprehension agnosia not being able to recognize speech ii The lower part of the cerebral cortex it plays a role in hearing understanding language and storing autobiographical memories iii Contains the auditory cortex and Wernicke s area responsible for speech comprehension f II Frontal i Speech production movement complex thinking aspects of personality 1 Damage production aphasia not being able to produce good speech ii Oversee and organize most other brain function executive functioning iii The prefrontal cortex is responsible for thinking planning and language iv Broca s area important in speech comprehension Examples of Systems a Basal Ganglia i Required for normal movement ii Allows us to preform movements to obtain reward and reinforcement iii Damage can contribute to Parkinson s disease b Limbic System i Amygdala emotion plays key in fear excitement and arousal ii Hippocampus learning and memory learning new things may be hard 1 You will never forget a hippo on campus iii Thalamus relays information from the sense organs to primary sensory cortex iv Hypothalamus regulates and controls internal bodily states controls the pituitary glands v Cingulate Cortex processes learning c Cerebral Cortex i Somatosensory homunculus little man ordered map of skin surface in III parietal cortex 1 Adjacent points remain adjacent 2 Some regions have more cortex devoted to them Some Organizing Principles a Plasticity i Cortex is plastic malleable based on experience b Mapping i Which side do we use 1 Left fine tuned language skills action 2 Right simple speech and writing visuospatial skills
