Tissue destruction.
Lesion
An amplified recording of the waves of electrical activity sweeping across the brain surface. These waves are measured by electrodes placed on the scalp
EEG (electroencephalogram)
A brain imaging technique that measures magnetic field from the brains natural electrical activity
MEG (magnetoencephalography)
A Series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice of the brain structure
CT cat scan (computed tomography scan)
A visual display of brain activity that detects where a radioactive form of glucose goes all the brain performs a given task
PET (positron emission tomography scan)
A technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue, shows brain anatomy
MRI (magnetic resonance imaging)
Technique for revealing blood flow and therefore brain activity by comparing successive MRI scans.
fMRI (functional MRI)
The oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; is responsible for automatic survival functions
Brainstem
The base of the brain stem; controls heartbeat and breathing
Medulla
The brains sensory control center, located on top of the brainstem; it direct messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
Thalamus
A nerve Netwerk that travels through the brain stem into the thalamus and plays an important role in controlling arousal
Reticular formation
The little brain at the rear of the brainstem; functions include processing sensory input, coordinating movement output and balance, and enabling nonverbal learning and memory
Cerebellum
Neural system located below the cerebral hemispheres, associated with emotions and drives
Limbic system
Two Lima-bean size neural clusters in the limbic system; linked to emotion
Amygdala
A neural structure line below the thalamus; it directs several maintenance activities including eating, drinking, body temperature, and helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward
Hypothalamus
A neural center located in the limbic system; helps process for storage explicit conscious memories of facts and events
Hippocampus
The intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body’s ultimate control and information processing center
Cerebral cortex
Involved in speaking and muscle movements and making plans and judgments
Frontal lobes
Receives sensory input for touch and body position
Parietal lobes
Includes areas that receive information from the visual fields
Occipital lobes
Includes the auditory areas, each receiving information primarily from the opposite ear
Temporal lobes
An area at the rear of the frontal lobe that controls voluntary movements
Motor cortex
An area at the front of the parental lobe’s that registers and processes body touch and movement sensations
Somatosensory cortex
Areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking
Association areas
