Vasculature

Arteries - Large vessels that carry oxygenated blood from the heart to the rest of the body, including the brain
Arterioles - Small arteries
Capillaries - Very small, thin walled vessels where oxygen is extracted
Veins - bring deoxygenated blood back to the heart

Blood Flow

• Neurons consume about 20% of the oxygenated blood flowing from the heart
• This blood reaches “the fine-grained capillary bed in the brain”
  • Capillaries are very thin, diameter of about 10 micrometers
    

More Anatomy:

Brain Stem - A set of three vertically aligned structures—the medulla, pons, and midbrain—that lie at the base of the brain and are essential for the regulation of bodily homeostasis.

Thalamus:

• On top of the brain stem
• Bilaterally symmetrical
• Relay station of the brain
• Contains:
  • Medial geniculate nucleus (MGN) - Audition
  • Lateral geniculate nucleus (LGN) - Vision
• All known connections between thalamus and cerebral cortex are reciprocal, two way radiations (thalamocortical and corticothalamic)

Hippocampus

• One in each hemispere, deep in the temporal lobe
• Essential for encoding of long term declarative memories

covered HM
how did they know that the MTL was the culprit for his epilepsy?

Amygdala

• Patient SM’s amygdala did not develop, and she was not able to recognize fear in herself or others

Gross Neuroanatomy

• 1 - Lateral Sulcus. Very important for navigating brain
• 7 - Central Sulcus. Divides frontal and parietal lobes
  
• General pattern of dividing:
  1. Superior
  2. Middle
  3. Inferior
