Flashcards in Final Exam Telencephalon Deck (21):
1

Left hemisphere is known for:

Grammar, vocabulary, Linear reasoning

2

Right hemisphere is known for :

Prosodic language (facial movement), Spatial manipulations

3

Outer convoluted grey cerebral cortex also called:

The pallium

4

Underlying mass of the white fibers collectively called:(under the pallium)

Centrum semiovale

5

Deep w/in the white matter are collections of neuron cell bodies called the:

Basal ganglia

6

What are the 4 lobes:

Frontal (largest)
Temporal
Parietal
Occipital (smallest)

7

Telencephalon is the initiation center for?

Voluntary actions

8

Telencephalon is the final integration of:

Neural mechanisms

9

True or false a function of the telencephalon is memory & associative memory

True

10

Serves as basis for much of our emotional response aka:

Abstract thinking

11

What are the subdivisions of the cortex?

Neocortex & allocortex

12

What are the 6 common laminae of the neocortex? (external to internal)

Molecular I
External granular II
External pyramidal III
Internal granular IV
Internal pyramidal V
Multiform VI

13

- The outer most lamina & nearest to the pia mater
- Filled w/ synaptic activity

Molecular Lamina I

14

- Small closely- packed granular neurons
- Axons extends into deeper lamina of the same cortex area
- Sometimes called the "INTRAcortical Association" layer

External granular layer Lamina II

15

- Small pyramidal - shaped neuron cells bodies
- Axons extend out of the cortex to the white matter & then return to the gray matter. (described as projection, association, or commissural fibers)
- Sometimes called the "INTERcortical Association" layer

External Pyramidal layer Lamina III

16

Lamina II & III are called the:

Associative lamina

17

Which lamina are the best developed in the human brain?

Lamina II & III

18

- Small closely packed cell bodies
- The specific THALAMIC INPUTS arrive here
(some thalamic input will reach the molecular layer, as well)
- Well developed in sensory areas (touch, pain, sight, hearing)

Internal granular layer lamina IV

19

- Large pyramidal - shaped neuron cell bodies
- Even giant pyramidal (Betz) cells are found in certain areas
- Axons "project" to other brain & cord centers from here. (ex. Corticospinal, Corticobulbar fibers)

Internal pyramidal (ganglionic) layer lamina V

20

- Mix of incoming & outgoing fibers passing through
- Also has a number of projection neurons

Multiform layer lamina VI

21

Laminae V & VI are sometimes called the?

Projection laminae
