Brain Plasticity Flashcards
What is it? Role of experience as a factor for changes in the brain Factors that stimulate it Changes in sensory representations after amputation.
What is brain plasticity?
Any change in neuronal structure or function. It is an intrinsic property of the nervous system retained throughout life.
What is brain plasticity in response to?
Enriched experience, training and practice.
To brain injury.
What can be modified with experience?
Sensory and MOTOR MAPS
What happens with visual cortex when there is no visual input?
Primary visual cortex was activated when performing a braille reading task, but not in passive tactile stimulation (touching meaningless braille symbols)
Sadato et al. (1996, 1998) used PET to examine activation of visual cortex.
What did the blindfold experiments provide evidence of?
That transient visual deprivation in sighted participants is sufficient to recruit visual cortex for tactile processing.
Excessive practice and predisposing factors (i.e genetic) may lead to… what?
Unwanted cortical rearrangement and disease.
Musicians were prone to what disorder?
Dystonia, distorted motor maps.
Suggest a treatment for phantom limb pain
Mirror visual feedback MVF
What is neurogenesis?
Process by which new neurons are formed in the brain.
Stress influences on the brain, evidence of damage or shrinking of the…. Following traumatic events
Hippocampus
What is present during lifetime?
Neuroplasticity
What is also present in the adult brain?
Neurogenesis
What is adaptive and maladaptive?
Brain plasticity
