Action

  • Monosynaptic stretch reflex
    • Also called "myotatic"
    • Polysynaptic component
  • Intrafusal/extrafusal muscle fibers
    • Extrafusal == produce force
    • Intrafusal == take up slack in muscle spindles
  • Parkinson's, Huntington's
  • Wolpert's ideas about role of brains in movement planning

Somatosensation

  • Functional segregation
    • Different receptors detect different qualities/dimensions
  • What information projects to brain fastest & why?
    • Thick axons & thick myelin -> proprioception from muscle spindles
  • Similarities to, differences from vision, audition
  • Relation between sensitivity, receptor density, receptive field size, and corresponding cortical area.
    • Higher sensitivity == > density, < receptive field size, > cortical area size

Disorders

  • Serotonin/monoamine hypothesis of depression, treatments
  • Treatments for bipolar disorder
  • Dopamine hypothesis of schizophrenia & alternative

Emotion

  • Plutchik
  • Fear, stress circuits
  • Reward/happiness circuits
    • Milner & Olds stimulation experiment

Sleep

  • Suprachiasmatic nucleus, melatonin

Hormones

  • Oxytocin
  • Cortisol

Evolution

  • Relative brain sizes among mammals

Neuroanatomy

  • Ventricles
  • Lobes of the cerebral cortex
  • Parts of the brain

Neurophysiology

  • Resting, action potentials
  • Postsynaptic potentials, end plate potential (muscle fiber)
  • Role of Ca++ in
    • Synaptic communication
    • Muscular contraction

Next time

  • Exam 3
