Study Notes
Cerebrum Overview
- The cerebrum is the uppermost region of the brain, divided into two large hemispheres.
- The cerebral cortex, about one inch thick, is responsible for complex mental functions such as thought, planning, perception, and consciousness.
- Basic physiological functions do not require memory retrieval.
- Simple behaviors, such as hitting the snooze button on an alarm clock, demonstrate fundamental nervous system principles.
Lobe Functionality
- The cerebrum comprises three main lobes: frontal, parietal, and temporal.
- Frontal lobes, positioned only on the left side, are highly interconnected with other brain regions, facilitating diverse functions.
- Parietal lobes focus on abstract thinking and impulse control.
- Temporal lobes, situated directly above the frontal lobes, are primarily involved in movement control and process auditory information.
Memory and Coordination
- The hippocampus plays a crucial role in forming long-term memories.
- The cerebellum is essential for balance, coordination, and specific cognitive activities.
- The medulla regulates vital functions such as body temperature and digestion.
Neuron Structure and Function
- Glial cells provide structural support and enhance communication between neurons, which process and transmit information across the nervous system.
- Neurons are the fundamental units of the nervous system, with information transmitted via chemical signals.
- Dendrites receive signals, passing them to the cell body, while axons carry signals away to neighboring neurons.
- The myelin sheath protects electrical signals from interference, and end bulbs are located at the tips of axon's branches.
Visual and Emotional Processing
- The primary visual cortex is located within the temporal lobes, contributing to visual processing.
- Neurons in the visual cortex are not specialized for distinct aspects of vision.
- The amygdala is integral for recognizing and recalling emotional experiences.
- The thalamus is not involved in relaying sensory information to the cortex.
