the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
area of neurons running down the front of the parietal lobes responsible for processing information from the skin and internal body receptors for touch, temperature, body position, and possibly taste
that part of the cerebral cortex in either hemisphere of the brain lying directly behind the forehead
that part of the cerebral cortex in either hemisphere of the brain lying in the back of the head, used in sight
Part of the brainstem that controls vital life-sustaining functions such as heartbeat, breathing, blood pressure, and digestion.
the "little brain" attached to the rear of the brainstem; its functions include processing sensory input and coordinating movement output and balance
that part of the cerebral cortex in either hemisphere of the brain lying inside the temples of the head, portion that lies below the frontal lobe, responsible for hearing, taste, and smell
portion posterior to the frontal lobe, responsible for sensations such as pain, temperature, and touch
part of the brain, works with the cerebellum in coordinating voluntary movement; neural stimulation studied in activation synthesis theory may originate here
Loss of function associated with damage to a specific area of the left frontal lobe, demonstrated by impairment in producing understandable speech.
Aphasia resulting from damage to the Wernicke's area of the frontal lobe. Affects written and spoken language. random
the intricate fabric of interconnected neural cells that covers the cerebral hemispheres; the body's ultimate control and information-processing center
split brain procedure
a condition in which the two hemispheres of the brain are isolated by cutting the connecting fibers (mostly those of the corpus callosum) between them
emotions- fear, aggression- and codes memories, two almond-shaped neural clusters that are components of the limbic system and are linked to emotion
creates memories, a neural center located in the limbic system that helps process explicit memories for storage
reflexes and body functions- breathing, heart beat eetc., the base of the brainstem; controls heartbeat and breathing.
movement, like cerebellum, A set of subcortical structures that directs intentional movements.
movement, fine motor skills, balance and coordination, the "little brain" attached to the rear of the brainstem; it helps coordinate voluntary movement and balance
cut cat's spinal chords and observed results- paw still reflexed when touched to hot object
transcranial magnetic stimulation
Direct stimulation of the cerebral cortex induced by magnetic fields generated outside the skull, non-invasive stimulation of the brain caused by a rapidly changing electrical current in a coil held over the scalp
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.
Are made by a process that uses multiple x-ray images to create three-dimensional images of body structures. Used to help identify tumor & cancers located in an organ. Are much more definitive that x-rays.
positron emission tomography
(PET) a visual display of brain activitythat detects where radioactive form glucose goes while the brain performs a given task. finds the energy users
magnetic resonance imaging
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. (MRI) negatives- tissues with little H content,
functional magnetic resonance imaging
a form of magnetic resonance imaging of the brain that registers blood flow to functioning areas of the brain
Surgical instruments with a hollow barrel(or lumen) through their center. Cannulas are often inserted for drainage
a sudden loss of consciousness resulting when the rupture or occlusion of a blood vessel leads to oxygen lack in the brain
divisions of the nervous system
Somatic nervous system (branches into sensory nerve fibers and motor nerve fibers) and autonomic nervous system (breaks into afferent nerves and efferent nerves- splits into parasympathetic n.s. and sympathetic n.s.)
inability to recognize and identify objects/persons despite having the knowledge of the characteristics of objects or the persons; disorder of perception
