Study Notes
Brain Overview
- The brain is the central data center of the body, controlling thoughts, feelings, and behaviors.
- Located in the cranial cavity, it consists of three main parts: cerebrum, cerebellum, and brainstem.
- The cerebral cortex is the largest part of the brain, associated with higher-level functions including sensory interpretation, speech, reasoning, and emotional processing.
Cerebral Hemispheres
- The cerebrum has two hemispheres, right and left, joined by the corpus callosum for inter-hemispheric communication.
- Each hemisphere controls the opposite side of the body due to contralateral control.
- The left hemisphere is dominant for language, analytical thought, and motor control of the right side.
- The right hemisphere excels in creativity, spatial abilities, and interpreting non-verbal cues and emotions.
Language and Aphasia
- Broca's area (left frontal lobe) is critical for speech production; damage leads to Broca's aphasia, characterized by difficulty speaking but preserved understanding.
- Wernicke's area (left temporal lobe) is essential for language comprehension; damage leads to Wernicke's aphasia, resulting in fluent but nonsensical speech and poor comprehension.
Brain Lobes
- Each hemisphere is divided into four lobes: frontal, parietal, temporal, and occipital.
- The frontal lobe (thinking, planning, memory) is at the front; the parietal lobe (touch processing) is in the middle; the occipital lobe (visual information) is at the back; the temporal lobe (hearing, language) is below the parietal lobe.
Cerebellum
- Located under the cerebrum, the cerebellum coordinates voluntary movements, maintains balance, and is involved in motor learning.
- Damage to the cerebellum results in issues with coordination and stability, while alcohol consumption affects its functioning.
Brainstem
- The brainstem regulates vital life functions such as respiration, attention, and motor responses; it connects the cerebrum and cerebellum to the spinal cord.
- Composed of the medulla, which controls heart rate and breathing, and the pons, which helps regulate movements and equilibrium.
Limbic System
- The limbic system, situated between the brainstem and the cerebral hemispheres, manages emotions, memory, and behavior.
- Key components include:
- Amygdala: governs fear and aggression responses, learning from threatening experiences.
- Thalamus: processes and relays sensory information and helps regulate sleep.
- Hypothalamus: regulates hunger, thirst, body temperature, and emotional responses through interactions with the endocrine system.
- Hippocampus: essential for the formation of long-term memories; damage leads to an inability to create new memories.
Cognitive Psychology
- Cognitive psychologists study information acquisition, perception, processing, and memory storage.
- Technologies like MRI help researchers visualize brain activity and investigate how structural differences affect health, personality, and cognitive function.
