Study Notes

Brain Structure and Development

The brain is not the largest cluster of neurons in the body.
Vertebrate brains develop axially from the midline dorsal nerve cord as a vesicular enlargement at the rostral end of the neural tube.
Invertebrate brains arise from paired segmental ganglia of the ventral nerve cord.

Vertebrate Brain Development

Vertebrate brains can be embryonically divided into four parts: forebrain, midbrain, hindbrain, and spinal cord.

Brain Regions and Functions

The cerebrum is the largest part of the human brain.
The neocortex is composed of six neuronal layers.
The occipital lobe is associated with visual processing, not executive functions like self-control and reasoning.
Each hemisphere of the brain is conventionally divided into four lobes: frontal, parietal, temporal, and occipital.
Some functions are associated with one side of the brain, for example, language is associated with the left hemisphere, not the right hemisphere.
