Study Notes
Key Brain Structures and Functions
- Hippocampus: Crucial for learning and memory, part of the limbic system.
- Pons: Plays a role in sleep regulation and arousal.
- Medulla: Regulates unconscious functions such as breathing and circulation.
- Reticular Formation: A network of fibers in the brainstem that controls sleep and arousal responses.
- Spinal Cord: Transmits signals between the brain and body, also initiates simple reflexes.
- Brainstem: Oversees essential automatic functions needed for survival.
- Cerebellum: Coordinates fine motor movements and maintains balance.
Limbic System and Emotional Processing
- Amygdala: Involved in processing emotions and aggression, part of the limbic system.
- Cerebrum: Handles complex cognitive functions like thinking, learning, emotions, and voluntary actions.
- Corpus Callosum: Connects the two cerebral hemispheres, facilitating communication between them.
- Thalamus: Serves as the relay station for sensory information, connecting it to the cerebral cortex.
- Hypothalamus: Regulates basic biological needs including hunger, thirst, and body temperature.
Cerebral Cortex Regions
- Frontal Lobe: Engaged in speech, muscle movements, planning, and judgment-making processes.
- Motor Cortex: Located at the rear of the frontal lobe, it is responsible for controlling voluntary movements.
- Sensory Cortex: Positioned at the front of the parietal lobes, it processes touch and body movement sensations.
- Parietal Lobe: Receives and interprets sensory data; crucial for combining letters and words into coherent thoughts.
- Occipital Lobe: Primarily processes visual information.
Language and Cognitive Areas
- Association Areas: These regions of the cerebral cortex are engaged in higher mental processes like learning and memory but do not manage primary sensory or motor functions.
- Aphasia: A form of language impairment resulting from damage in the left hemisphere; may affect speaking or comprehension based on the impacted area.
- Broca's Area: Located in the frontal lobe, it directs the muscles involved in speech production.
- Wernicke's Area: Situated in the left temporal lobe, essential for language comprehension and production.
Special Conditions
- Split Brain: A condition arising from severing the corpus callosum, leading to isolation of the brain's hemispheres and distinct functional behaviors.
