Aaron Jennings Chapter 3B Vocab Flashcards
An amplified recording of the waves of electrical activity that sweep across the brains surface. These waves are measured by electrodes placed on the scalp
Electroencephalogram
A series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body
CT scan
A visual display of brain activity that detects where a radioactive form of glucose goes well the brain performs a given task
PET scan
It’s technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue
MRI
A technique for revealing blood flow and therefore brain activity by comparing successive MRI scans
F MRI
The oldest part and central core of the brain, beginning where the spinal cord swells as it enters the school; the brainstem is responsible for automatic survival functions
Brainstem
The base of the brainstem controls heartbeat and breathing
Medulla
A nerve network in the brainstem that plays an important role in controlling arousal
Reticular formation
The brain 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
Thalamus
The “little brain “at the rear of the brainstem; Rossons include processing sensory input and coordinating movement output and balance
Cerebellum
Donuts Saint neural system located below the cerebral hemispheres; associated with emotions and drives
The limbic system
To lima bean size neural clusters in the limbic system; linked to emotion
Amygdala
Neural structure lying below the thalamus; it directs several maintenance activities; helps govern the endocrine system via move it to a pituitary gland, and is linked to emotion and reward
Hypothalamus
The intricate fabric of interconnected neural cells covering the cerebral hemispheres; the bodies ultimate control and information processing center
Cerebral cortex
Cells in the nervous system that support, nervous, and protect neurons
Glial cells
