Lecture 1 - Human Brain

Question 1

Foetal development of brain segments?

Answer 1

3 lumps w tail - forbrain (cortex with thalamus inside the lump), midbrain, and hindbrain (medulla, pons, cerebellum)

Question 2

Cingulate gyrus location and function?

Answer 2

superficial to corpus callosum, complex higher-order thinking

Question 3

Broca’s area location and function?

Answer 3

bottom of motor planning area homunculus immediately anterior to facial region of primary motor cortex; motor planning of speech

Question 4

Temporal association cortex function?

Answer 4

memory

Question 5

Parietal association cortex function?

Answer 5

3D recognition e.g. faces, non-verbal language and music (right side).

Question 6

Cells of the primary motor cortex?

Answer 6

pyramidal shape, size proportional to distance travelled by axon

Question 7

Order of homonculus - deep to superficial?

Answer 7

face, eyes, hand, torso, leg, foot

Question 8

Wernicke’s area location and fucntion?

Answer 8

superior temporal gyrus, suppression of sounds and focus

Question 9

Reading and writing areas of brain and connection?

Answer 9

supramarginal and angular gyrus, connected to motor planning of hands and eyes

Question 10

Primary auditory cortex location, function and coding?

Answer 10

superior temporal gyrus within Wernicke’s area, perception of incoming sound, matrix interpretation

Question 11

Arcuate Fasciculus function and deficit?

Answer 11

relay from Wernicke’s to Broca’s to generate verbal response to sound; connectional aphasia
