Study Notes
Consciousness
- Consciousness is our subjective awareness of ourselves and our environment
Sleep and Dreams
- EEG recordings show brain activity during sleep, even when exposed to sounds.
Circadian Rhythm
- A circadian rhythm is a regular bodily rhythm, like temperature and wakefulness, occurring over a 24-hour cycle.
- This rhythm is regulated by a biological clock.
- Thinking and memory are sharpest during peak circadian arousal.
Bright Light and Circadian Clock

- The body's natural rhythm is slightly longer than 24 hours, approximately 25 hours.
