Study Notes
Higher Functions of the Brain
- Higher functions include sleep, memory, cognition, emotion, sensation, motor control, and language.
- These functions are essential for complex behaviors and interaction with the environment.
Brain Parts Involved in Integrative Functions
- The cerebral cortex is primarily responsible for higher-order brain functions.
- Basal nuclei play a role in movement control and cognitive functions.
- The brainstem manages vital life functions and connects different brain regions.
- The cerebellum is crucial for coordination and balance, supporting integrative functioning.
Alpha Waves
- Frequency range: 8-13 Hz.
- Present when awake, resting with eyes closed, and mind wandering.
- Suppressed when eyes are open or during mental tasks, indicating engagement.
Beta Waves
- Frequency range: 14-30 Hz.
- Occur with eyes open and during active mental tasks.
- Heightened during periods of sensory stimulation and cognitive engagement.
Theta Waves
- Frequency range: 4-7 Hz.
- Common in drowsy or sleeping adults, indicating deeper relaxation.
- Can also appear when awake under emotional stress, showing heightened emotional states.
