Q

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

A
  1. short axons that act as interneurons

2. glutamate (excitatory) GABA (inhibitory)

2
Q

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

A
  1. perform intracortical associated functions
3
Q

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

A
  1. specific sensory signals terminate
4
Q

What is the thalamocortical system?

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

Q

What areas analyze the meaning of specific sensory signals?

A

secondary sensory area
