16
Q

Oligodendrocytes

A
  • myelinate axons in the CNS only
  • do not support axonal regeneration
  • do not clean up debris
  • upregulate molecules that inhibit axonal growth
17
Q

Schwan Cells

A
  • facilitate axonal regeneration and debris clean-up in the peripheral nervous system
  • originate from the neural crest
18
Q

Astrocytes

A
  • mediate blood flow
  • metabolize potassium
  • form scar in CNS which provides a physical barrier that impairs axonal growth
  • originate from neuroectoderm
  • instruct endothelial cells to from BBB
  • GFAP is astrocyte marker
19
Q

Microglia

A
  • macrophages of the nervous system
  • microglial response is rapid and short-lived
  • activate more chronic astrocyte response
  • microglia release inhibitory factors which create poor environment for axonal regeneration in the CNS
  • pharmacologic target
20
Q

Nissl Bodies

A
  • rough ER in cytoplasm of neurons

- make proteins from mRNA

21
Q

Cajal

A
  • discovered neurons as functional unit

- neuronal doctrine

22
Q

Penfield

A

-electrical stim mapping

23
Q

Hebb

A

-fire together, wire together plasticity

24
Q

Kandel

A

-gene transcription changes plasticity
