tissue destruction. A brain lesion is a naturally or experimentally caused destruction of brain tissue
the base of the brainstem; controls heartbeat and breathing
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.
the brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
computed tomography (CT)
brain-imaging method using computer-controlled X-rays of the brain
a nerve network in the brainstem that plays an important role in controlling arousal
Positron Emmission Tomography (PET)
The amount of metabolic activity in the brain is assessed by measuring the tissue's uptake of a (harmless) radioactive sugar.
A large structure of the hindbrain that controls fine motor skills.
magnetic resonance imaging (MRI)
brain-imaging method using radio waves and magnetic fields of the body to produce detailed images of the brain
neural system located below the cerebral hemispheres; associated with emotions and drives
fMRI (functional MRI)
A technique for revealing bloodflow and, therefore, brain activity by comparing successive MRI scans. fMRI scans show brain function.
two lima bean-sized neural clusters in the limbic system; linked to emotion.
Connection to spinal cord. Filters information flow between peripheral nervous system and the rest of the brain.
A neural structure lying below the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward.
A neurotransmitter associated with movement, attention and learning and the brain's pleasure and reward system.
a subcortical structure that participates in reward and addiction
