SYSTEMS NEUROSCIENCE
Notes
HISTORY OF NEUROSCIENCE
Hippocrates: brain = thought (emotion).
Aristotle: heart = thought.
Galen: heart = pump; brain = thought. He performed dissections in order to localize organs and
function. (He poked).
NEURO ANATOMY
Exterior view
- Dorsal = towards the back. (top)
- Ventral = towards the belly. (bottom)
- Lateral = towards the side.
- Midial = towards the middle.
- Rostral (anterior) = towards the front.
- Caudal (posterior) = towards the butt.
*Localization for human is quite different because of the way we stand up (two legs).
Interior view (cuts)
- Mid-sagital.
- Horizontal.
- Coronal (frontal).
Words
Nucleus: 1) cell structure that houses DNA/ collection of neurons in CNS (referred in this class).

Ganglion: collection of neurons in PNS.
Tract: bundle of axons in the CNS.
Nerve: bundle of axons in the PNS.
Afferent: carry to (information) a point
Efferent: carry from (information) a point.
Gross organization
PNS = somatic & autonomic (sympathetic & parasympathetic). Mostly sensory and motor.
- Somatic PNS = innervates skin, joints, muscles. (voluntary movement)
- Visceral PNS (autonomic nevus system) = innervates organs, blood, vessels and glands
(involuntary).
- Sympathetic (JAZZING things up) “ flight or fight”. Nerves mostly lead to the spinal.
chord.
- Parasympathetic (housekeeping). “Eat and chill and toke up”. Nerves mostly lead directly
to the target tissue from the brain.
CNS = brain & spinal cord. “thinking”.
for this class we use CORTEX instead of CEREBRUM.
Major Structures
Cranial nerves: 12 pairs.
Ventricles: where the CSF flows.
Meninges:
- Dura mater.
- Arachnoids membrane. (Underneath the Dura mater)
- Pia mater. (closest to the brain).
