Q

Thalamus

A

(THINK RELAY) part of the diencephalon within the forebrain. Projects information to specific areas of the cerebrum, and controls which information is sent to the cerebral cortex

17
Q

Occipital Lobe

A

Vision

18
Q

What primodrial structure is folded deep within the lateral sulcus? What does it do?

A

Insular Complex : effects conciousness, emotion, homestasis – compassion, empathy, perception, self-awareness, etc…

19
Q

Heschls gyrus

A

primary auditory cortex, located within the lateral sulcus (think inside of the temporal lobe

20
Q

What layer of what cortex has huge betz cells?

A

Layer V of the primary motor cortex

21
Q

BA: 3,1,2

A

primary somatosensory cortex (postcentral gyrus) - projects to primary motor (BA4)

22
Q

BA4

A

primary motor cortex (precentral gyrus)

23
Q

BA 5 & 7

A

posterior parietal cortex - important sensory feedback to organize movement (sends info to BA 8/6, which sends infor to BA4)

24
Q

BA 8/6

A

Premotor/supplementary motor: receives input from the parietal lobe and projects to primary motor - responsible for organizing/planning sequence of muscle activation

25
Q

BA 44 & BA45 (BROCAS AREA)

A

Located in the frontal lobe of dominant hemisphere (usually left) - in the inferior frontal gyrus
Speech Production

Affected by stroke can lead to loss of language.

26
Q

BA 22

A
  • part of the superior temporal gyrus
  • Includes wernikes area, which is a language processign region
  • Left side of brain: generation and understanding of words
  • Right side: pitch and sound intensity discrimination
27
Q

BA 41 & 42

A

Primary Auditory Cortex

  • Heschl’s Gyrus + part of superior temporal gyrus
  • Located Bilaterally
28
Q

BA 17

A

Primary Visual Cortex

29
Q

Pathway in the Limbic System

A

From Amygdala to Hippocampus to Fornix to Mamillary Body to Hypothalmus

30
Q

What are some of the key white matter bundles and what do they do?

A 
Anterior Commissure= Connects temporal lobes, esp. Amygdala 
Posterior Commissure (Connects L & R hindbrain)
Corpus Callosum (Connects L & R Brain)
31
Q

Internal Capsule

A

KEY WHITE MATTER BUNDLE

Runs throughout inside of brain and connects mtor cortex to body

32
Q

The Dorsal striatum is made up of, and functions in?

A

Caudate and putamen, functions in (cognitive and motor functions ), relays info to Basal Ganglia to thalamus then to Primary Motor Cortex.

33
Q

Ventral Striatum is also called

A

Nucleus Accumbens

34
Q

What areas in the Ventricular System contain choroid plexus?

A

Body of Lateral Ventricles, 3rd Ventricle, 4th Ventricle

35
Q

What areas in the Ventricular System do not contain choroid plexus?

A

Anterior or Posterior Horns of lateral ventricles, Cerebral aqueduct
