Sc B-62 Section 3

Quiz:

My favorite image collection for parts: http://www.mhhe.com/socscience/intro/ibank/set1.htm

  • part; location; function
  • neocortex; outside of brain stem/limbic system; higher thinking, perception, motor, emotion etc...
  • frontal lobe; front part of neocortex between central fissure and lateral fissure; short term memory, social intelligence, decision making, impulse control, "workhorse" or higher thought (Richard), Brocha's area (grammatical functions), includes the motor cortex
  • brainstem; coming from spine into mid brain;
  • hippocampus; inside the temporal lobe; part of the limbic system (together with thalamus, hypothalamus and amigdila), Alzheimer's attacks this, responsible for encoding new memories (Alzheimer's supposedly cannot gain new memories but they can learn new motor skills if that part is not damaged, e.g. learn to play a new instrument (but then how do they remember what melody to play?!?!?!)), Parkinson's attacks basel ganglia hurting fine motor movements, London taxi drivers study showed that their right hippocampus was larger than normal, and the longer they have been driving the larger it was > spacial memory and direction
  • right hemisphere; right half of brain; creative side, because more white matter, intonation, music, rote memory, faces, creativity correlates with depression > more -ve than left hemisphere
  • pons; above thalamus, below mid brain (?); balance, heart rate, breathing, closely related to cerebellum
  • visual cortex; very back of head, on the occipial lobe; vision
  • sylvian fissure = lateral fissure
  • left hemisphere
  • cerebellum
  • synapse
  • hypothalamus
  • striatum
  • axon fibers
  • grey matter
  • white matter
  • temporal lobe
  • forebrain
  • central fissure
  • spinal cord
  • parietal
  • medulla oblongata
  • lobe-limbic microelectrodes
Apparition of Jesus: habituation/fatigue from firing
Border effect: lateral inhibition
