hormones like adrenaline, which help the body respond to stress.
Adrenal Glands
The “master gland” that controls other glands in the
body and regulates growth, metabolism, and reproduction.
Pituitary Gland
Damage to brain tissue, often used in research to study brain
functions.
Lesion
A test that measures electrical activity in
the brain using electrodes placed on the scalp.
EEG (Electroencephalogram)
A brain imaging technique that
measures magnetic fields created by brain activity.
MEG (Magnetoencephalography)
An imaging technique that uses X-
rays to create detailed pictures of the brain.
CT (Computed Tomography) Scan
A brain imaging technique
that shows which parts of the brain are active by tracking glucose usage.
PET (Positron Emission Tomography) Scan
A technique that uses magnetic
fields and radio waves to create detailed images of the brain.
MRI (Magnetic Resonance Imaging
A technique that measures brain activity by
detecting changes in blood flow, showing which parts of the brain are
fMRI (Functional MRI)
The oldest part of the brain that controls basic survival
functions like heartbeat and breathing.
Brainstem
The part of the brainstem that controls vital functions like
heart rate and breathing.
Medulla
The brain’s “relay station” that sends sensory information to
the appropriate areas of the brain for processing.
Thalamus
A network of nerves in the brainstem that helps
regulate alertness and sleep.
