computer enhanced x-rays used to create brain images are known as
computed tomography scans (CT)
what part of the brain triggers the release of adrenaline to boost heart rate when your afraid?
a gymnast falls and hits her head on the floor. She attempts to continue practicing, but has trouble maintaining balance. What part of her brain has probably been affected?
which of the following scanning techniques measures glucose consumption as an indicator of brain activity?
positron emission tomography scan (PET)
which of the following is sometimes referred to as the brain's train hub, because it directs incoming sensory messages (with the exception of smell) to their proper places in the brain?
which of the following brain areas is responsible for regulating thirst?
the hypothalamus is a(n) __________ center for the brain.
which of the following's primary function is processing memories?
What parts of mikes brain have most been affected by his head injury if he struggles to control his emotions and has difficulty establishing new memories?
- damage to the amygdala would make it difficult for him to control his emotions.
- damage to the hippocampus would affect his ability to establish new memories.
tissue destruction. A naturally or experimentally caused destruction of brain tissue
an amplified recording of the waves of electrical activity sweeping across the brains surface. These waves are measured by electrodes placed in the scalp.
CT (computed tomography) scan
a series of W-ray photographs taken from different angles and combined by computer into a composite representation of a slice of the brains structure. (AKA CAT scan)
PET (positron emission tomography) scan
a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task.
MRI (magnetic resonance imaging)
a technique that uses magnetic fields and radio waves to produce computer generated images of soft tissue. MRI scans show brain anatomy.
fMRI (functioning MRI)
a technique for revealing blood flow and therefore brain activity by comparing successive MRI scans. fMRI scans show brain function as well as its structure.
the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skulls; responsible for autonomic survival functions
the base of the brainstem; controls the heartbeat and breathing
the brain's sensory control center, located on the top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
a nerve network that travels through the brainstem and thalamus and plays an important role in controlling arousal
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
neural system (including the hippocampus, amygdala, and hypothalamus) located below the cerebral hemispheres; associated with emotions and drive.
two lima bean sized neural clusters the mimic system; linked to emotion
a neural structure lying below the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps given the endocrine system via the pituitary gland, and is linked to emotion and reward
damage of what lobe of the brain could interfere with the ability to plan for the future?
in general, damage to ________ disrupts speaking, while damage to ________ disrupts understanding of language.
stimulation at a point on which part of the brain may cause a person to report being touched on the knee?
George can move his hand to sign a document because the ________, located in the ________ lobe of the brain, allows him to activate the proper muscles.
the most noticeable difference between human brains and other mammalian brain is the size of the...
cognitive neural prosthetics are placed in the brain to help control parts of the..
the intricate fabric of incinerated neural cells covering the cerebral hemispheres; the bodys ultimate control and information -processing center.
glial cells (glia)
cells int he nervous system that support, nourish, and protect neurons; they may also play a role in learning and thinking
portion of the cerebral cortex lying just behind the forehead. Involved in speaking and muscle movements and in making plans and judgements
portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory information from the visual fields.
portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields
portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear
an area at the rear of the frontal lobes that controls voluntary movements
area at the front of the parietal lobes that registers and processes body touch and movement sensations
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.
the brains ability to change, especially during childhood, by reorganizing after damage or by building new pathways based in experience
the formation of new neurons
A split brain patient has a picture of a dog flashed to his right hemisphere and a cat to his left hemisphere. He will be able to identify the..
cat using his right hand
you are aware that a dog is viciously barking at you, but you are not aware of the type pf dog. Later, you are able to describe the type and color of the dog. This ability to process information without conscious awareness best exemplifies...
which of the following is most likely to be a function of the left hemisphere?
the dual-processing model refers to.. give an example.
incoming information is processed by both conscious and unconscious tracks
the large band of neural fibers connecting the two brain hemispheres and carrying messages between them
a condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them
our awareness of ourselves and our environment
the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory and language)
the principal that information is often simultaneously processed on separate conscious and unconscious tracks.
What rib numbers are floating ribs?
What part of the brain stem connects the spinal cord and the brain?
How many tonsil types are there?
what bones make up the sub-talar joint?
