Flashcards
Occipital Lobe
Occipital Lobe
Processes visual information received from the eyes, turning light and shadows into images. It also makes assumptions about what we see.
Temporal Lobe
Temporal Lobe
Involved in hearing and object memory. It communicates with the occipital lobe to interpret visual information.
Aphasia
Aphasia
A condition, often caused by strokes, that impairs communication, making it difficult to understand others or form coherent sentences.

Study Notes
- The eyes perceive light, which is then transmitted to the occipital lobe, where it's converted into images.
- The occipital lobe makes assumptions about visual input, which can lead to optical illusions when it draws conclusions not based on reality.
Temporal Lobe
- Contains areas for hearing and object memory.
- Interacts with the occipital lobe to interpret visual information.
- Damage can result in aphasia, which impairs communication skills such as forming sentences or understanding speech, often resulting from strokes.
- Wernicke's syndrome is a rare memory disorder, is sometimes associated with alcohol abuse or malnutrition.
Parietal Lobe
- Damage may lead to hemispatial neglect.
- Responsible for proprioception, or awareness of body position and movement.
Frontal Lobe
- Controls movement and complex thought processes.
- Contains a map of the body's muscles.
Insular Cortex
- Controls taste perception.
- Responsible for awareness of the body's internal state.
- Monitors signals such as hunger (stomach) and pain and surprise (heart rate).

Description
The brain is divided into lobes, each with specific functions such as vision (occipital), hearing and memory (temporal), spatial awareness (parietal), movement and thought (frontal), and taste/internal state (insular). Damage to these areas can result in various impairments.
