Consciousness and Circadian Rhythms

Flashcards covering key concepts related to consciousness, brain activity, and circadian rhythms.

Consciousness

The state of being aware of and able to think about one's own existence, thoughts, and surroundings.

Mind Wandering

A phenomenon where thoughts stray from the current task, often leading to distractions.

Beta Waves

Brain wave patterns that are present when a person is awake and alert, characterized by 13 to 24 cycles per second.

Alpha Waves

Brain wave patterns that signify a relaxed yet alert state, typically occurring when a person is drowsy.

Circadian Rhythm

The physical, mental, and behavioral changes that follow a daily cycle, responding primarily to light and darkness.

Melatonin

A hormone that regulates sleep-wake cycles, secreted by the pineal gland in response to darkness.

Schrodinger Rhythms

Biological rhythms tied to the cycle of light and darkness, impacting sleep and wakefulness.

Thalamus

A brain structure that relays sensory and motor signals to the cerebral cortex and plays a role in consciousness.

Hypothalamus

A brain region that regulates various autonomic functions and the endocrine system, including sleep-wake cycles.

Neural Activity

The pattern of electrical impulses created by neurons in the brain, which contribute to conscious experience.
