Question 10

Serves as basis for much of our emotional response aka:

Answer 10

Abstract thinking

Question 11

What are the subdivisions of the cortex?

Answer 11

Neocortex & allocortex

Question 12

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

Answer 12

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

Question 13

• The outer most lamina & nearest to the pia mater

- Filled w/ synaptic activity

Answer 13

Molecular Lamina I

Question 14

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

Answer 14

External granular layer Lamina II

Question 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

Answer 15

External Pyramidal layer Lamina III

Question 16

Lamina II & III are called the:

Answer 16

Associative lamina

Question 17

Which lamina are the best developed in the human brain?

Answer 17

Lamina II & III

Question 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)

Answer 18

Internal granular layer lamina IV

Question 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)

Answer 19

Internal pyramidal (ganglionic) layer lamina V

Question 20

• Mix of incoming & outgoing fibers passing through

- Also has a number of projection neurons

Answer 20

Multiform layer lamina VI

Question 21

Laminae V & VI are sometimes called the?

Answer 21

Projection laminae
