Study Notes
Brain Functions and Development
- Emotion, thought, reasoning, memory, and precise, coordinated movement are accounted for by certain extremely specialized regions and structures within the brain.
- The brain-to-body weight ratio is a critical factor in brain development, even more important than the actual ratio itself.
Brain Characteristics
- The human brain typically weighs between 1,350 and 1,400 grams (3 pounds).
- The brain-to-body weight ratio is a significant indicator of brain development, with a larger ratio contributing to a more advanced brain.
