Study Notes
Brain Structures and Functions
- The cerebral cortex is the outer layer of the brain, responsible for higher-level cognitive functions like thinking, perceiving, and decision-making.
- The cerebral cortex is highly folded to increase its surface area, enabling complex neural processing and integration of information.
- Grey matter contains the cell bodies of neurons, crucial for "thinking" processes.
- White matter consists of myelinated axons, acting as "wiring" to transmit signals between brain regions.
Lobes of the Brain
- The brain is divided into four lobes: frontal, parietal, temporal, and occipital.
- These lobes are regions within the cerebrum involved in different functions.
Association Areas
- These areas integrate information from various parts of the brain, enabling us to understand the world around us.
- They're involved in processing sensory input from sight, smell, touch, and more.
Frontal Lobes
- Located at the front of the brain, frontal lobes are involved in higher-level cognitive functions, including decision-making, problem-solving, planning, and personality expression.
- Like a head chef in a restaurant, the frontal lobe handles high-level coordination duties.
Prefrontal Cortex
- A region within the frontal lobe, responsible for higher-level cognitive functions and executive functioning.
- Executive functions include planning, decision-making, and self-control.
- This region is crucial for focusing attention, managing time, strategizing, and regulating emotions.
Motor Cortex
- Located in the frontal lobe, responsible for planning, executing, and controlling voluntary movements of the body.
- It sends signals to muscles to enable actions like walking, talking, and grasping objects.
Parietal Lobes
- Located at the top of the brain, responsible for processing sensory information like touch, temperature, and spatial awareness.
- These lobes help in accurately judging distances, speeds, and trajectories.
Somatosensory Cortex
- Located in the parietal lobe, responsible for processing sensations from the skin, muscles, and joints.
- It interprets touch, pressure, temperature, and pain signals from different body parts.
Occipital Lobes
- Located at the back of the brain, responsible for processing visual information from the eyes.
- The primary visual cortex within this lobe interprets visual stimuli, enabling us to perceive shapes, colors, and motion.
Temporal Lobes
- Located on the sides of the brain, involved in processing auditory information, language comprehension, and memory formation.
- The auditory cortex within this lobe interprets sound signals and aids in understanding language and forming memories.
Corpus Callosum
- A thick band of nerve fibers that connects the left and right hemispheres of the brain.
- Facilitates communication and information sharing between the two hemispheres, crucial for coordinated actions.
Brainstem
- The oldest and most primitive part of the brain, responsible for basic life-sustaining functions including breathing, heart rate, and sleep-wake cycles.
- Serves as a pathway for neural signals traveling between the brain and the rest of the body.
Medulla
- Located at the base of the brainstem, regulating essential autonomic functions like heartbeat and breathing.
- Acts as a relay station for nerve signals traveling between the brain and the spinal cord.
Reticular Activating System
- A network of neurons in the brainstem that regulates arousal, attention, and consciousness.
- Filters sensory information and modulates brain activity, aiding in wakefulness and alertness.
Cerebellum
- Located at the back of the brain, responsible for coordinating movement, balance, and posture.
- Receives input from sensory systems and other parts of the brain to fine-tune motor movements and ensure smooth coordination.
Limbic System
- Structures beneath the cerebral cortex involved in emotions, memory, and motivation.
- Includes different areas like the thalamus, basal ganglia, hippocampus, amygdala, and hypothalamus.
Reward Center
- Network of brain structures primarily located in the limbic system.
- Processes pleasurable experiences and reinforces behaviors associated with them.
Thalamus
- A relay station in the brain that processes and relays sensory information, like sight, sound, touch, and taste, to the cerebral cortex.
- Acts as a gateway, directing signals to the appropriate areas of the brain for further processing.
Hypothalamus
- A small, powerful structure below the thalamus, responsible for regulating various essential bodily functions including hunger, thirst, body temperature, and the sleep-wake cycle.
- Serves as a control center maintaining homeostasis in the body.
Pituitary Gland
- A small, pea-sized gland at the base of the brain, often referred to as the "master gland".
- Plays a critical role in coordinating hormonal activity and maintaining homeostasis in the body.
Hippocampus
- A curved structure within the brain's temporal lobes, responsible for forming and consolidating new memories.
Amygdala
- A small, almond-shaped structure deep within the brain's temporal lobes, involved in processing emotions, particularly fear and aggression.
- Plays a central role in the brain's threat detection system.
Iconic Brain Project
- Students create a "pseudo" brain model of a famous individual, drawing on their creativity (from celebrities to fictional characters).
- Encourages students to think neurologically by visualizing the characteristics of personalities through brain structure representation.
