Neuroplasticity
the ability within the brain to constantly change both the structure and function of many cells in response to experience or trauma
neurogenesis
the formation of new neurons
PET scan
a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
MRI
a technique that uses magnetic fields and radio waves to produce computer-generated images that distinguish among different types of soft tissue; allows us to see structures within the brain
fMRI
A technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans.
EEG
An amplified recording of the waves of electrical activity that sweep across the brain's surface. These waves are measured by electrodes placed on the scalp.
split brain
a condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them
circadian rhythm
internal body clock
NREM-1
the transition into sleep, marked by slowed breathing and irregular brain waves; hypnagogic sensations/hallucinations, and myclonic jerks may occur
NREM-2
Sleep stage characterized by its periodic sleep spindles, or bursts of rapid, rhythmic brain-wave activity. About half the night is spent in this phase.
NREM-3
sleep stage that lasts about 30 minutes and your brain emits large, slow delta waves, and you are hard to awaken.
REM
describes sleep in which vivid dreams typically occur; this type of sleep increases as the night progresses while stage 4 sleep decreases
sleep apnea
a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings
Insomnia
recurring problems in falling or staying asleep
narcolepsy
A sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times.
