Sleep
24-hour biological cycle regulating sleep and wakefulness
Circadian rhythm
Perceptual experiences without external stimuli
Hallucinations
Creates 3D images of brain structure using multiple x-rays
CT Scan
Involved in executive functions, planning, and movement.
Frontal Lobes
Regulates breathing, heartbeat, and other vital functions.
Medulla
Electroencephalogram measuring brain's electrical activity
EEG
Chemicals altering consciousness similar to brain's.
Psychoactive drugs
Visualizes brain structure using magnetic fields.
Magnetic Resonance Imaging (MRI)
Connects cortex to spinal cord; regulates basic functions.
Brain Stem
Specialized for vision; processes visual information.
Occipital Lobe
Type of brain wave present during sleep stage 1
Theta waves
Need for increased drug amount for effect.
Tolerance
Measures glucose consumption for neural activity.
Positron Emission Tomography (PET scan)
Part of frontal lobe controlling body movements.
Motor Cortex
Master gland controlling other glands; releases growth hormones.
Pituitary Gland
Hormone regulating sleep-wake cycles, increasing at night
Melatonin
Used for fatigue, euphoria, or street use.
Amphetamines
Uses magnetic fields to alter brain function.
Magnetoencephalography (MEG)
Sensitive to touch, pain, and temperature sensations.
Somatosensory cortex
Release adrenaline and cortisol during emotional arousal.
Adrenal Glands
The literal content of the dream is called
manifest content
Opiates for pain relief and sleep induction.
Narcotics
Uses magnetic fields to alter brain function.
Transcranial Magnetic Stimulation (TMS)
Involved in hearing, language comprehension, and memory.
Temporal Lobe
Connects cortex to cerebellum; triggers dreaming.
