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.
