Study Notes
Consciousness and Awareness
- Consciousness encompasses our awareness of both internal and external stimuli.
- Internal awareness includes sensations such as pain, hunger, thirst, sleepiness, and self-referential thoughts.
- External awareness involves perceiving environmental elements like sunlight, room temperature, and sounds, such as a person speaking.
States of Consciousness
- Sleep is characterized by low physical activity and diminished sensory awareness, differentiating it from periods of mere rest.
- Intermediate states of consciousness include daydreaming, intoxication from substances like alcohol, meditative practices, hypnotic states, and altered consciousness after sleep.
Biological Rhythms
- Biological rhythms, such as the menstrual cycle, illustrate natural cycles within the body.
- Body temperature experiences cyclical changes over a 24-hour period, with higher temperatures linked to higher alertness.
- The suprachiasmatic nucleus (SCN) serves as the brain's internal clock, located in the hypothalamus, regulating the sleep-wake cycle as a circadian rhythm.
