Term
The term for a fabricated or made-up word
Definition
neologism
Term
a component of Long Term Memory, the ability to recall events/information that occurred in the distant past (i.e. several years ago)
Definition
remote memory
Term
inability to perform purposive movements although there is no sensory or motor impairment
Definition
apraxia
Term
a common condition following brain damage in which patients fail to be aware of items to one side of space
Definition
hemi-neglect
Term
impairment in the expression and/or comprehension of language.
Definition
aphasia
Term
small, involuntary contraction/relaxation "twitching" of muscles; usually harmless
Definition
fasciculations
Term
involuntary contractions/relaxation of muscles that looks like a tremor and is often a sign of immature nervous system in babies or irregularity in a person with a nervous system disorder
Definition
clonus
Term
extensive neglect and failure to recognize one’s own body paralysis. Results from lesions to the right hemisphere
Definition
anosognosia
Term
impairment in making smooth, rapid alternating movements of the extremities
Definition
dysdiadokokinesis
Term
partial loss of the ability to perform coordinated movements
Definition
dyspraxia
Term
occurs after the sole of the foot has been firmly stroked: the big toe moves upward and other toes fan outward
Definition
Babinski Response
Term
a disturbance of the power to control the range of movement in muscular action
Definition
dysmetria
Term
a form of hypertonia with an involuntary variable resistance during passive movement
Definition
Gegenhalten
Term
a condition characterized by involuntary swinging or jerking movements, which is due to neurological damage
Definition
Ballism
Term
the exciting of a single sensory neuron by incoming impulses from multiple other neurons (negative = outward deviation; position = inward deviation)
Definition
convergence
Term
difficulty with speech due to impairment of oral motor structures or musculature
Definition
dysarthria
Term
tingling sensation that can be found in the distal part of the nerve (not severe, usually just unpleasant)
Definition
Hoffman's Sign
Term
release/resistance in a quick, jerky movement, commonly seen in Parkinson's Disease
Definition
cogwheeling
Term
a tremor that occurs when a limb is resting in a relaxed state, fully supported
Definition
resting tremor
Term
the repetition of a particular response, such as a word, phrase, or gesture, despite the absence or cessation of a stimulus, usually caused by brain injury or other organic disorder
Definition
perseveration
Term
involuntary rapid movements of the eyes
Definition
nystagmus
Term
the tracking of one's eyes of a slowly moving object at a steady coordinated velocity rather than in saccades
Definition
smooth pursuit
Term
occurs during voluntary movement of a limb and increases as the limb gets closer to the goal. The tremor is a rhythmic oscillation of joints caused by alternating contractions. Tremor stops when limbs are at rest, sign of cerebellar damage
Definition
intention tremor
Term
a symptom characterized by slow, involuntary, convoluted, writhing movements of the fingers, hands, toes, and feet and in some cases, arms, legs, neck and tongue
Definition
athetosis
Term
an electrical sensation that runs down the back into the limbs
Definition
Lhermitte's Sign
Term
lack of muscular coordination (due to a neurological condition)
Definition
ataxia
Term
visual impairment in which an object is seen as two objects (double vision)
Definition
diplopia
Term
a symptom of a possible neurological deficit identified by neurological test to detect poor balance. Specifically, it detects the inability to maintain a steady standing posture with the eyes closed. A positive result is excessive swaying or even falling over.
Definition
Rhomberg Sign
Term
a nerve cell
Definition
neuron
Term
the part of the neuron that brings information to the cell body
Definition
dendrite
Term
the part of the neuron that takes information away from the cell body
Definition
axon
Term
the junction between two neurons
Definition
synapse
Term
the two main divisions of the nervous system
Definition
the central nervous system and the peripheral
nervous system (CNS and PNS)
Term
the area of the brain responsible for thought, language, and planning
Definition
cerebral cortex
Term
connects the right and left hemispheres of the brain
Definition
corpus callosum
Term
the man who survived after an iron rod went through the frontal lobe of his brain in 1848
Definition
Phineas Gage
Term
symptoms of Alzheimer's Disease
Definition
memory loss, dementia, depression, social withdrawal; plaques and tangles
Term
a disease characterized as an electrical “brainstorm”
Definition
epilepsy
Term
A condition characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic hallucinations
Definition
narcolepsy
Term
A disease transmitted by ticks; has symptoms of joint pains, chills, fever and headache
Definition
Lyme Disease
Term
Has symptoms of weakness, paralysis, death of neurons in the motor cortex and spinal cord; named for a famous baseball player
Definition
amyotrophic lateral sclerosis (ALS/Lou Gehrig’s Disease)
Term
general term for someone who studies the nervous system
Definition
neuroscientist
Term
A test that uses detection of radio frequency signals produced by displaced radio waves in a magnetic field
Definition
MRI
Term
A test that records electrical activity of the brain with scalp or brain electrodes
Definition
EEG
Term
A test that detects radioactive material that is injected or inhaled to produce an image of the brain
Definition
PET scan
Term
A test that uses a series of X-ray beams passed through the head
Definition
CT scan

the sense of sight
Definition
vision
Term
The lobe of the brain important for hearing
Definition
