impact to cerebal cortex and adaptive plasiticity

Question 1

brain injury

Answer 1

refers to any brain damage that impairs or interefers with the nomral functioning of the brain, either temporarily or permanetly.
-can happen suddenly or insidious on set

Question 2

acquire brain injury

Answer 2

brain damage that occurs after birth (ABI)

Question 3

Most common cause of an ABI

Answer 3

A stroke occurs when a blood vessel bringing oxygen adn nutrients to the brain bursts or is glogged. As a result, the brain tissues is deprived of blood, causing the brain cells to die within minutes.

Question 4

Traumatic brain injury (TBI)

Answer 4

Acquired brain injury caused by a blow to the head or by the hed being forced to move rapidl yforward or backwards, usually with some loss of consciounesses.

Question 5

biopsychosocial changes due to frontal lobe

Answer 5

biologcal: range of problems with motor activities
psychological: impacting behaviour, lack of emtional response, impulsive behaviour, forgetfulness
socail: personality changes and difficult establishing relationships

Question 6

brain plasticity

Answer 6

brain plastcity refers to the ability of the brain to change in response to experinces

• occurs at the synapse
• modification can occur when young, during learning or through brain injury

Question 7

adaptive plasticity

Answer 7

• ability of the brain to compensate for lost function and/or to maximise remaining function in the event of brain injury
• brain comensates for the injury by reorganising its dtructure

Question 8

adaptive plasticity after injury

Answer 8

Sprouting and re-routing enables the formation of entirely new neural connections to compensate for the loss of functions due to brain injury (within the CNS)
RE-ROUTING- - an undamaged neuron that has lost connections with an active neuron may seek a new active euron and connect with it instead
SPROUTING- the growth of additional branches as axons or dendrites to enable new connections therefore this involves re-routing also
