Study Notes
Brain Lobes
- The brain has four lobes: frontal, temporal, parietal, and occipital.
- Each lobe is responsible for specific functions.
- Brain functions rely heavily on the collaboration of different brain areas.
Frontal Lobe
- Functions: Motor movement, higher-order thinking (cognitive skills), decision-making, organization, planning, problem-solving, personality (behavior and emotion control), language.
- Broca's area: Responsible for articulate speech production.
- Trauma: Can lead to personality changes.
- Dementia: Can occur if part of the frontal lobe dies.
Temporal Lobe
- Functions: Auditory information (hearing), language.
- Wernicke's area: Responsible for understanding language (written and verbal communication).
Parietal Lobe
- Functions: Sensations, touch, taste, smell, temperature (hot/cold).
Occipital Lobe
- Functions: Sight (visual processing of visual information), seeing colors, perceiving/recognizing people/objects.
Limbic System
- Located in the central parts of the brain.
- Vital for human life.
- Protected by the brain lobes.
- Structures include the hypothalamus, amygdala, and hippocampus.
Hypothalamus
- Controls hunger, thirst, and sleep.
- Releases hormones.
- Regulates the "fight or flight" response.
Amygdala
- Associated with emotions.
- Plays a significant role in anxiety and the "fight or flight" response.
Hippocampus
- Associated with memory.
- Damage can cause memory loss (e.g., in epilepsy).
- Grief can negatively impact memory, cognition, and concentration.
Thalamus
- Relays sensory and motor information.
Hindbrain
- Includes the brainstem and cerebellum.
- Brainstem connects the brain to the spinal cord, controlling vital functions like breathing and heartbeat.
Pons
- Connects the brain and upper brainstem.
- Coordinates signals and communication in the central nervous system.
Medulla
- Connects the lower brainstem to the spinal cord.
- Contains control centers for vital functions (heart rate, blood pressure, breathing).
Cerebellum
- Responsible for motor coordination (affected by alcohol).
Memory
- Encoding: Taking information and storing it.
- Storage: Keeping information for later use.
- Retrieval: Recalling memories.
- Memory formation: Encoding input, storing memory, recalling memory.
Memory Processes
- Sensory memory: Holds sensory information briefly (seconds).
- Short-term memory: Filters and selects information; encodes it for potential long-term storage. Has limitations (7 ± 2 items)
- Chunking: Grouping items to increase short-term memory capacity.
- Displacement: Older information is replaced by new information.

Description
This quiz explores the four main lobes of the brain: frontal, temporal, parietal, and occipital. Each lobe's specific functions and roles in cognitive processes, language, sensory perceptions, and visual processing will be assessed. Understand how these areas work together to support overall brain function.
