Study Notes
What is Consciousness?
- Consciousness is a state of awareness of oneself and one's surroundings. It encompasses our thoughts, feelings, sensations, and perceptions.
The Brain and Sleep-Wake Cycles
- The hypothalamus, specifically the suprachiasmatic nucleus (SCN), plays a crucial role in regulating the sleep-wake cycle.
Circadian Rhythms
- Circadian rhythms are biological processes that occur on a roughly 24-hour cycle, influenced by the cyclical patterns of light and darkness.
Sleep Deprivation
- Sleep deprivation refers to a state of insufficient sleep, resulting in physical, cognitive, and emotional impairments.
Restoration Theory
- The restoration theory suggests that sleep is essential for the body's physical and mental restoration, allowing for repair and rejuvenation.
Theta Waves
- Theta waves are brainwave patterns characterized by their slow, rhythmic oscillations, typically present during drowsiness and light sleep stages.
REM Sleep
- Rapid eye movement (REM) sleep is a stage of sleep marked by rapid eye movements, increased brain activity, and vivid dreaming.
Stage One Sleep
- During non-REM stage one sleep, the brain transitions from awake to a state of light sleep. This stage is characterized by slowing of brain waves and muscle relaxation.
Sleep Across Lifespans
- Infants tend to experience a higher proportion of REM sleep compared to adults. This suggests that REM sleep may be vital for brain development.
