Study Notes
Cerebral Cortex
- The outermost layer of the cerebrum, responsible for processing sensory information and controlling movement
- Divided into four lobes: frontal, parietal, temporal, and occipital
- Composed of:
- Grey matter: neuronal cell bodies and dendrites
- White matter: myelinated axons
- Functions:
- Sensory perception
- Motor control
- Attention
- Memory
- Language processing
Basal Ganglia
- A group of structures located at the base of the cerebrum
- Involved in movement control and cognition
- Components:
- Caudate nucleus
- Putamen
- Globus pallidus
- Subthalamic nucleus
- Substantia nigra
- Functions:
- Motor control
- Habit formation
- Reward-based learning
- Cognitive flexibility
Limbic System
- A network of structures involved in emotion, motivation, and memory
- Components:
- Hippocampus
- Amygdala
- Hypothalamus
- Cingulate gyrus
- Fornix
- Functions:
- Emotion regulation
- Memory formation
- Motivation
- Arousal
Brain Hemisphere
- The cerebrum is divided into two hemispheres: left and right
- Each hemisphere is responsible for controlling the opposite side of the body
- Functions:
- Left hemisphere: language processing, logic, and analytical thinking
- Right hemisphere: spatial processing, creativity, and intuition
The Four Lobes
-
Frontal Lobe
- Located in the front of the cerebrum
- Involved in:
- Motor control
- Executive functions (decision-making, planning)
- Language processing
-
Parietal Lobe
- Located near the center of the cerebrum
- Involved in:
- Sensory processing (touch, spatial awareness)
- Attention
- Memory
-
Temporal Lobe
- Located on the sides of the cerebrum
- Involved in:
- Auditory processing
- Memory formation
- Language processing
-
Occipital Lobe
- Located at the back of the cerebrum
- Involved in:
- Visual processing
