Flashcards in Brain Function Lecture 03 Deck (15):
1

How do granular neurons look like and what do they secrete?

1. short axons that act as interneurons

2. glutamate (excitatory) GABA (inhibitory)

2

The first three layers of the cerebral cortex perform what tasks?

1. perform intracortical associated functions

3

What happens in the 4th layer of the cerebral cortex?

1. specific sensory signals terminate

4

What is the thalamocortical system?

1. this system consists of ongoing neural signals between nuclei in the thalamus and neurons in all modular areas of the cortex.

5

What is responsible for the direct connection with the cerebral cortex and specific muscles?

primary motor areas

6

What areas is responsible for detecting specific sensations?

primary sensory areas

7

What area of the brain provides patterns of motor activity?

secondary motor areas

8

What areas analyze the meaning of specific sensory signals?

secondary sensory area

9

The parieto-occipitotemporal association area is responsible for what?

1. analyze spatial coordinates
2.angular gyrus area
3. area to name objects

10

The prefrontal association area is responsible for what?

1. receive preanalyzed sensory information that is necessary for planning effective movement.

2. the thought processes are carried to basal ganglia through the caudate portion.

11

What is Broca's area responsible for?

1. helps with word formation
2. works closely with wernicke's area and mostly dominant on the Lt side of brain

12

What is most associated with the Limbic area of the brain?

1. behavior
2. emotions
3. motivation

13

What is Wernicke's area most well known for?

1. language comprehension

14

What components all come together at Wernicke's area, in the posterior superior temporal lobe?

1.somatic association area
2. visual association area
3. auditory association area.

15

What are the different cortical neurons?

1. granular (stellate) neurons

2. Fusiform neurons

3. Pyramidal neurons
