Study Notes
Cerebral Cortex
- Divided into four lobes: frontal, parietal, temporal, and occipital
- Frontal lobe: Controls motor activity, speech, planning, and impulse control
- Parietal lobe: Integrates sensory information and helps with spatial tasks
- Temporal lobe: Processes auditory perception, memory, and emotions
- Occipital lobe: Responsible for visual perception
Lateralization of Function
- Sperry (1981) showed brain hemisphere specialization
- Left hemisphere: Language, computation, and logical reasoning
- Right hemisphere: Spatial reasoning, face recognition, and music appreciation
- Corpus callosum: Connects the two hemispheres
Contralateral Organization
- Visual processing and muscle/limb control are contralaterally organized (opposite sides)
Action and Vision
- Brain injury (e.g., stroke) can affect face, arm, speech, and time perception
Split Brain Patients
- Left visual field: Processed by the right hemisphere
- Right visual field: Processed by the left hemisphere
- Fixation point: A central point for visual attention in experiments
Basal Ganglia
- A collection of structures including caudate nucleus, putamen, and globus pallidus.
- Plays a role in movement control.
- Damage to the basal ganglia is implicated in Parkinson's disease.
