PRELIMS: Reviewer Flashcards
These are spinal networks capable of generating bilateral rhythmic movements, such as swimming or walking, in the absence of descending and sensory inputs
Central Pattern Generators (CPG)
PLASTIC RESPONSE INCREASING THE SENSITIVITY TO PROPRIOCEPTIVE STIMULUS
Up Regulation
PLASTIC RESPONSE THAT INCREASES SENSITIVITY TO NEUROTRANSMITTERS AND HORMONES
Up Regulation
This neuronal plasticity is described as: reactivation of latent neuronal connections in response to partial deafferentation of a target cell population
Unmasking
This none associative learning is described as there is a reduction in the amplitude of synaptic potential
This neuronal plasticity is described as: reinnervation of a vacated synapse by an intact collateral branch of the injured axon; seen to occur in CNS, but takes months to occur
Pruning
PLASTIC RESPONSE SEEN IN CHRONIC EPILEPTIC PATIENTS
SYNAPTIC REORGANIZATION
a process whereby neurons extend from their place of birth to connect to far reaching areas of the brain.
neural migration
natural death of a neuron
APOPTOSIS
Neuroplasticity is the brain’s ability to
A. Only adapt during childhood
B. Change and rewire itself
C. Stay rigid and unchanging
B. Change and rewire itself
This subcomponent of the ITE model is stated as: “goal directed movements
ACTION
This is the process that occurs in the CNS that increases the control of the cerebral hemispheres
CORTICAL REORGANIZATION
The brain’s ability to adapt to injury or damage by redistributing functions to undamaged areas is known as:
C. Functional reorganization
“coordination of movement is the process of mastering the redundant degrees of freedom of the moving organism”
BERNSTEINS
simpler reflexes combine to make up the behavior of an individual
REFLEX THOERY
Normal motor development is the result of increasing corticalization or emergence of higher level reflexes to control over the lower level reflexes
HIERARCHICAL THEORY
no need for higher center to issue instruction or give command because coordinated movement will be achieved no matter what
SYNAMIC SYSTEMS THEORY
Higher level stores the rules for generating movements so that we can perform the tasks with a variety of effector systems
: GENERALIZED MOTOR PROGRAM THEORY
This subcomponent of the ITE model is stated as: Mental functions underlying the establishment of a goal
COGNITIVE FACTORS
What is the primary mechanism by which long-term potentiation (LTP) enhances synaptic strength
A. Decrease in neurotransmitter release
B. Increase in receptor density at the synapse
C. Increase in synaptic vesicle size
B. Increase in receptor density at the synapse
reinnervation of a vacated synapse by an intact collateral branch of the injured axon; seen to occur in CNS, but takes months to occur
: pruningg
reactivation of latent neuronal connections in response to partial deafferentation of a target cell population; PET (Positron emission tomography) reveals high metabolic activity in the visual cortex of blind persons
UNMASKING
the response of a remote uninjured neuron, that reinnervates a foreign denervated target
neuronal ingrowth
the response by the proximal portion of an injured axon to reinnervate its original synapse; done by PNS, not seen in CNS though
Axonal Regeneraltion
