36-NSCI 2101 - Cerebral Cortex 1 - 2024

What are the dates for Lab 11?

Lab 11 is from December 2-5.

What type of cortex makes up most of the human cerebral cortex?

Neocortex makes up most of the human cerebral cortex.

How many layers does the neocortex have?

The neocortex has six layers.

What are the two main types of cerebral cortex?

Neocortex and allocortex are the two main types of cerebral cortex.

What is a defining feature that separates humans from lower mammals?

The size and complexity of the cerebral cortex.

What type of neurons are pyramidal neurons?

Large neurons with long dendrites that are the primary source of axons leaving the cortex.

What cell type is primarily found in Layer II of the gray matter of cortex?

Granule cells are primarily found in Layer II.

What does Layer IV of the gray matter of cortex primarily consist of?

Layer IV is composed primarily of granule cells receiving input from the thalamus.

What is a major function of the visual cortex columns?

These columns respond to the orientation of shapes, ocular dominance, and color.

Who developed Brodmann's areas?

Korbinian Brodmann

What do Brodmann’s areas correspond to in the cortex?

Brodmann’s areas correspond to the cytoarchitecture of the layers of the cortex.

How does the input from the thalamus vary for the different lobes?

Each lobe has specific thalamic inputs, such as the occipital lobe receiving input from the lateral geniculate nucleus.

What are the primary dysfunctions associated with damage to the frontal lobe?

Memory issues, personality changes, and emotional deficits.

What lobes make up the human cerebral cortex?

Frontal, parietal, occipital, temporal, and limbic lobes.

What is the role of the uncinate fasciculus?

It connects the frontal and temporal lobes.

What are symptoms of damage to the parietal lobe?

Agraphia, memory generation issues, and loss of sensation.

What brain functions are typically localized to the left side of the brain?

Speech functions such as Broca’s area and Wernicke’s area.

What is the significance of split-brain patients?

They demonstrate that function is mostly normal even after the corpus callosum is severed.
