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
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
