Summary of "2-Minute Neuroscience: Cerebral Cortex"
- Structure of the Cerebral Cortex:
- The Cerebral Cortex is the outermost layer of the brain.
- Composed primarily of gray matter.
- Highly folded to form ridges (gyri) and grooves (sulci).
- Folding increases surface area, allowing for more neural components.
- Types of Cortex:
- Neocortex:
- Makes up most of the human Cerebral Cortex.
- Considered evolutionarily recent.
- Neurons arranged in six distinct layers differing in cell type and density.
- Allocortex:
- Has a more variable layering pattern.
- Mesocortex:
- Transitional area between Neocortex and Allocortex.
- Neocortex:
- Functional Subdivisions:
Although functional divisions can oversimplify, the cortex is commonly divided into:
- Sensory Areas:
- Receive sensory information.
- Include primary somatosensory cortex (touch, pain, temperature).
- Primary Visual Cortex.
- Primary auditory cortex.
- Areas for olfaction, taste, and vestibular senses.
- Motor Areas:
- Involved in movement.
- Include Primary Motor Cortex, premotor cortex, and supplementary motor cortex.
- Association Areas:
- Integrate information from multiple brain regions.
- Add complexity to sensory perceptions.
- Support higher cognitive functions.
- Parietal cortex association areas: attention and perceptual awareness.
- Frontal cortex association areas: planning, impulse control, self-awareness.
- Sensory Areas:
