Cerebral cortex laminae

Question 1

Lamina 1

Answer 1

Molecular Layer

Most superficial layer containing horizontal neurons of Cajal.

Question 2

Lamina 2

Answer 2

External granular layer with small pyramidal neurons and many small stellate neurons

Important for processing sensory information.

Question 3

Lamina 3

Answer 3

Pyramidal layer (external pyramidal) with medium and large pyramidal neurons and few small stellate neurons

Involved in cortical processing.

Question 4

Lamina 4

Answer 4

Internal granular layer with small stellate neurons

Plays a role in sensory input integration.

Question 5

Lamina 5

Answer 5

Ganglionic layer (internal pyramidal) with large and medium pyramidal neurons and small stellate neurons

Key for output to subcortical structures.

Question 6

Lamina 6

Answer 6

Multiformic layer (fusiform) and the deepest layer with modified pyramidal neurons

Involved in feedback to the thalamus.
