Study Notes
Brain Cortex Structure
- The brain cortex is the outer layer of the brain, comprising gray matter.
- The brain cortex is divided into different parts, each with its own function.
Brain Cortex Functions
- The brain cortex is responsible for processing complex information and performing various functions.
- It is the most complex part of the nervous system, responsible for controlling emotions, sensations, and movements.
Sensory and Motor Functions
- The brain cortex receives sensory information from the environment and body.
- It processes this information and sends signals to the body to respond accordingly.
- Examples of sensory functions include:
- Vision: processing visual information from the eyes.
- Touch: processing tactile information from the skin.
- Examples of motor functions include:
- Movement: controlling muscle movements.
- Balance: maintaining balance and coordination.
Hemispheres of the Brain
- The brain is divided into two hemispheres: left and right.
- Each hemisphere has its own functions and responsibilities.
- The left hemisphere is responsible for:
- Language processing.
- Logical reasoning.
- The right hemisphere is responsible for:
- Spatial awareness.
- Creativity.
Brain Cortex Divisions
- The brain cortex is divided into four main parts: frontal, parietal, temporal, and occipital.
- Each part has its own specific functions and responsibilities.
- The frontal lobe is responsible for:
- Executive functions.
- Decision-making.
- The parietal lobe is responsible for:
- Processing sensory information.
- Integrating sensory information.
- The temporal lobe is responsible for:
- Processing auditory information.
- Memory formation.
- The occipital lobe is responsible for:
- Processing visual information.
Association and Primary Cortex
- The association cortex is responsible for integrating information from different senses.
- It is located in the parietal and temporal lobes.
- The primary cortex is responsible for processing basic sensory information.
- It is located in the frontal, parietal, temporal, and occipital lobes.
Higher-Order Functions
- The brain cortex is responsible for higher-order functions such as:
- Attention.
- Emotions.
- Consciousness.
- These functions are distributed across different parts of the brain cortex.
Language Processing
- Language processing is a complex function that involves multiple parts of the brain cortex.
- It is primarily located in the left hemisphere.
- The Broca's area and Wernicke's area are responsible for language processing.
Attention
- Attention is a complex function that involves multiple parts of the brain cortex.
- It is responsible for focusing on specific stimuli and filtering out irrelevant information.
- The frontal and parietal lobes are responsible for attention.
Conclusion
- The brain cortex is a complex and dynamic system that is responsible for many functions.
- Understanding the structure and functions of the brain cortex is essential for understanding human behavior and cognition.

Cerebral Cortex Overview
- Gray matter layer on the cerebrum's surface with ridges (gyri) and grooves (sulci) and larger grooves called fissures.
Lobes of the Cerebral Cortex
- Four main lobes: frontal, parietal, temporal, and occipital, each named after the bone of the skull above it.
Functions of the Cerebral Cortex
- Responsible for complex information processing and nervous system functions, including sensory and motor functions.
- Processes visual information, with each side of the body's information primarily processed in the opposite side's occipital lobe.
- Processes somatosensory information, with each side of the body's information primarily processed in the opposite side's areas of cerebral cortex.
- Controls motor information, with each side of the body's information primarily controlled by the opposite side's areas of cerebral cortex.
Types of Cerebral Cortex
- Primary cortex performs basic motor or sensory functions.
- Association cortex integrates information for complex processing and functions, including planning, cognition, emotion, and consciousness.
Language and Attention
- Language function typically located in the left hemisphere, but some people have bilateral or right-sided language functions.
- Attention function involves both hemispheres, with the right hemisphere paying attention to both sides of the body and environment.
