Study Notes
Brain Structures
Cerebrum
- Divided into two hemispheres: left and right
- Responsible for:
- Processing sensory information
- Controlling movement and voluntary actions
- Managing higher-level cognitive functions (e.g., thought, emotion, memory)
Cerebral Cortex
- Outer layer of the cerebrum
- Divided into four lobes:
- Frontal Lobe: motor control, decision-making, planning
- Parietal Lobe: sensory processing, spatial awareness
- Temporal Lobe: auditory processing, memory
- Occipital Lobe: visual processing
Basal Ganglia
- Group of structures involved in movement control and cognition
- Components:
- Caudate nucleus
- Putamen
- Globus pallidus
- Subthalamic nucleus
- Functions:
- Motor control and coordination
- Habit formation and learning
- Emotion regulation
Brainstem
- Connects the cerebrum to the spinal cord
- Responsible for:
- Regulating basic functions (e.g., heart rate, breathing, blood pressure)
- Controlling arousal and consciousness
- Transmitting information between the cerebrum and spinal cord
Hippocampus
- Structure involved in memory formation and consolidation
- Plays a key role in:
- Spatial navigation and memory
- Emotionally charged memory formation
- Learning and memory consolidation
Amygdala
- Structure involved in emotion processing and fear response
- Functions:
- Detecting and processing emotional stimuli
- Triggering fear and anxiety responses
- Associating emotions with memories
Thalamus
- Relay station for sensory information
- Functions:
- Filtering and processing sensory information
- Transmitting information to the cortex
- Regulating consciousness and alertness
