|
structuralism
|
Edward Titchener, analyze consciousness into its basic elements and investigate how they are related

create myelin sheath (schwann cells only in PNS)
|
|
astrocytes
|
synchronize communication b/w neurons, nurtures cells, and removes waste products
"cleans up"
|
|
microglia
|
part of immune system, remove waste products
|
|
radial glia

guides migration and growth of immature neurons
|
|
EPSPs > IPSPs =
|
action potential in second neuron

|
|
4 lobes of cerebral cortex
|
occipital (visual), parietal (touch), temporal (auditory), frontal (motor skills)
|
|
vestibular system
|
Sense: Balance
Stimulus: Gravitational Pull
Process: Semicircular canals filled with vestibular sacs. Fluid w/in sacs moves and creates action potentials in hairs
|
|
Somatosensory system
|
Sense: feeling
Stimulus: heat/cold, mechanical pressure, vibrations, noxious stimuli
Process: polymodal nerves are embedded in the body, nociception (feeling of pain) only occurs if pain inhibitors are deactivated
