Study Notes
Brain Overview
- The brain is the central organ of the nervous system, controlling all bodily functions and interpreting external inputs.
- It weighs approximately 3.3 lbs (1.5 kg) and is housed within the skull.
- Composed of billions of neurons that transmit information via electrical impulses called action potentials.
Main Functions
- Governs aspects of intelligence, creativity, emotions, and memory.
- Comprises different parts that collaborate to perform various functions.
Brain Structure
- Main components include the cerebrum, cerebellum, and brainstem.
-
Cerebrum: The largest part, divided into right and left hemispheres; responsible for touch, vision, hearing, speech, reasoning, emotions, learning, and small movements.
- Contains four lobes:
- Frontal Lobe: Controls personality, behavior, judgment, planning, problem-solving, intelligence, speech, and body movement.
- Parietal Lobe: Interprets language and aids in visual recognition, spatial relationships, and pain/touch perception.
- Occipital Lobe: Responsible for vision and movement; located at the back of the brain.
- Temporal Lobe: Involved in short-term memory, speech, musical rhythm, and smell identification; located at the sides of the brain.
- Contains four lobes:
Cerebellum and Brainstem
- Cerebellum: Coordinates muscle movements, maintains posture, and balance.
- Brainstem: Acts as a relay center, controlling automatic functions such as breathing, heart rate, body temperature, and wake-sleep cycles.
Hemispheric Functions
- The brain consists of left and right hemispheres, each governing different body sides; left hemisphere controls the right body side and vice versa.
- Damage to one hemisphere can affect the opposite side of the body.
- Left-brain functions include logic, language, mathematics, and rational thinking.
- Right-brain functions include creativity, imagination, intuition, and empathy.
Dominance Theory
- Individuals may exhibit left or right-brain dominance based on their preferences:
- Right-brain dominant: Enjoy music, art, and social studies.
- Left-brain dominant: Prefer mathematics, science, and logical tasks.
- Both hemispheres can be developed through targeted activities, allowing for balanced cognitive abilities.
