10.13 Notes Flashcards
Hypothalamus
Made up of clumps of somas; each clump has a different function; important for daily rhythms and drives (drinking, eating, sleeping, temperature regulation, and sex) and alertness
Semantic memory
Facts
Episodic memory
Experience; involved in the hippocampus
H.M.
Suffered from seizures after an accident; surgically removed the hippocampus to relieve his seizures; suffered from anterograde amnesia Anna so he could not remember anything new consciously; he was able to remember being prepped with the pin by the doctor, but not the doctor
Amygdala
Fear and negative emotions
Corpus callosum
Tract of millions of axons that connects the two hemispheres
Cortex
Made up of six layers called laminae
Laminae I
Also known as neocortex; the outermost part of the cortex; the largest part of the cortex; sends info down; made of axons and glial cells
Laminae V
Made of huge pyramidal cells; sends info to the spinal cord, basal ganglia, and brainstem; voluntary motor movements
Laminae IV
Sensory info; gets most info from the thalamus
Primary area
An area that has information going directly
Secondary area
Integrates multiple pieces of info from various areas
Which area does sensory information go to?
Primary to tertiary
What area does motor information go?
Tertiary to primary
Primary visual cortex
V1; Area 17; damage here can cause blindsight, prevents conscious vision
Temporal lobe
Processes auditory stimulation; vision; emotions; facial recognition; Wernicke’s and Broca’s areas
In right-handed people, where is Wernicke’s area?
In the left temporal lobe
Frontal lobe
What makes you human and you personally; involved in planning, making decisions, source memory, inhibition of inappropriate behaviors, movement, and personality
Source memory
Remembering where you got a piece of information
Phineas Gage
Received frontal lobe damage; his personality completely changed
Primary motor cortex
Also known as the precentral gyrus; located in the frontal lobe; send info to your spinal cord about motor movements
Parietal lobe
Spatial processing; body sensations; primary somatosensory cortex
Primary somatosensory cortex
Also known as the postcentral gyrus; located in the parietal lobe; contains the map of the body for sensory info; pain
Limbic system
Composed of the olfactory bulb, hypothalamus, hippocampus, amygdala, cingulate gyrus; important for emotion, motivation, and memory
