Plasticity And Functional Recovery Of The Brain After Trauma Flashcards
Plasticity
Refers to neurological changes as a result of learning and experience
Functional recovery
Refers to brain functions moving from a damaged to an I damaged area after traumatic brain injury
How are new neural pathways caused
Learning and experiences cause new neural pathways to strengthen whereas pathways used infrequently become weak and die
Even. 60+ learning a new skill result in increased neural growth in the visual cortex
What does 30 minutes of video games do a day
Increase brain matter in the cortex, hippocampus and cerebellum
Forms new synaptic connections controlling spatial navigation l, planning and decision making
What is the experiment in meditating
8 experienced practionerz of mediation against 10 who do not do meditation
Level of gamma eats we Lee high Lee in experiences mediation group has their gamma ray levels were much higher
What are gamma rats associated with
Coordination of beau talks activity
Meditation increases brain plasticity causing permanent and positive changes to the brain
What was the study about the rays
Rats housed in more complex environments show increase in Neurons conapred to rats in simple houses
This causes changes in the hippocampus associated with memory and spatial navigation
What does the study about London taxi drivers
Posterior portion of the hippo of Apis was liarger than control group and positively correlated with the amount of time spent as a taxi driver
What does the brain have a function to do
Ability to re wire itself with undamaged brain sites taking over some functions or reverse no
What are the two main ways of functional recovery
Neuronal unmasking and stem cells
What is neuronal unmasking
Brain contains dormant synapses with measurable connection which have no functions
The synapses become activated and open up connection to regions of the brain which are not normally active and take over the neuronal function
What are stem cells
Unspecialised cells which become specially led to carry out different types of take
Stem cells used to aid recovery from brain trauma implanted to replace dead cells or to release substances which encourage growth or recovery of cells
What type of recovery is there between functional recovery and damaged cells
Negative
How do level of education correlate with speed of recovery
Positively correlated with speed of recovery from traumatic brain injuries
Patients with a college education were 7 times more likely to recover than those who did not finish college after 1 year
What is functional magnetic resonance imaging
Measures increased blood flow when individuals are asked to perform physical or cognitive tasks
Increased blood flow= demand for oxygen when a participant is asked to solve maths problems
