Quiz 6 detail oriented

Question 1

Who discovered that dmg to this region results in the inability to produce spoken language? Which NS principle does this ascribe to?

Answer 1

Broca - the ventroposterior area of the frontal lobe

- P9 - the brains functions are both localized and distributed

Question 2

Who discovered that dmg to this region results in the inability to comprehend language?? Which NS principle does this ascribe to?

Answer 2

Wernicke - the left posterior superior temporal gyrus

- P9 - the brains functions are both localized and distributed

Question 3

What are the 2 streams of visual information, and which principle does their distinction derive?

Answer 3

Ventral stream - occipital lobe to the temporal lobe for object recognition
Dorsal stream - occipital lobe to the parietal lobe for object-oriented movements
-P8 - Sensory input for object recognition and object-oriented movements are divided

Question 4

What are the 2 sub principles to the 7th principle? (ie that sensory and motor systems permeate the nervous system)

Answer 4

1. Separate cortical regions process different sensory input and motor outputs
2. The entire brain is organized around the distinction (law of Bell and Magendie )

Question 5

What are the 3 brain regions presented in principle 7 as examples?

Answer 5

Midbrain - tectum and tegmentum as sensory and motor distinct systems
Thalamus - seperate nuclei to control each of the sensory inputs, as well as certain motor outputs

Question 6

Explain Principle 6 in detail (the distinction between serial and parallel systems)

Answer 6

Serial - info is filtered from structures which determine its simple, then complex properties
Parallel - info is filtered through many different systems recognizing distinct information at the same time, which is accumulated into a single representation.

Question 7

what are the illnesses associated with rampant neuroplasticity of the brain/NS

Answer 7

Dementia, epilepsy and chronic pain.

Question 8

Plexus

Answer 8

Sheets of tissue surrounding viscera that contain the Ganglia of the ENS which connect to various cranial nerves (specifically the Vagus nerve)

Where does the spinal cord send information in order to integrate most sensorimotor info?

Answer 23

Cerebral cortex, thalamus

Question 24

Are cranical nerves contra or ipsolateral?

Answer 24

Isolateral
