Question 1

outline and define the role of the midbrain, hindbrain, and forebrain in regard to fighting within MMA

Answer 1

the forebrain functions with complex mental processes, attention and filtering sensory information. The cerebrum within this brain region works to coordinate voluntary muscle movements. - order to punch

the hindbrain functions to operate basic autonomic survival processes as the cerebellum maintains balance.- not falling in the fight by painting consciousness.

the midbrain relays messages to different brain regions and filtering/directing sensory information. the reticulum formation works to ensure the MMA fighter has high alertness and is in a state of consciousness.

Question 1

strengths and weaknesses of contemporary research

Answer 1

contemporary research is studies that have been conducted in the last 5-10 years that utilise modern technology.

strengths - Gives diseases more information through new techniques.

weaknesses - the long-term effects of new technology are unknown.

Question 2

neuroplasticity

Answer 2

is the ability of the brain to change it’s structure or function in response to experience or stimulation from the environment.

Question 3

adaptive plasticity

Answer 3

the brains ability to restore adequate neuaral functioning overtime sustaining injury.

Question 4

processes involved in neuroplasticity

Answer 4

synaptic pruning - the elimination of underused synapses.

myelination - the formation and development of myelin around the axon of a neuron. facilitates more efficient communication.

synaptogenesis - the formation of synapses between neurons as axon terminals and dendrites grow. It occurs when we learn something new and its most intense during infancy.

Question 5

sprouting and rerouting

Answer 5

rerouting- healthy neurons create alternative pathways when existing connections are lost.

sprouting- existing neurons form new axon terminals and dendrites to allow new connections to be made.

Question 6

whats an acquired brain injury and two examples

Answer 6

impacts on the brain that occur after birth.
-traumatic, which is an injury to the brain from an external force.
-non-traumatic, which is an injury to the brain from an internal force.

Question 7

MRI and CT

Answer 7

structural
MRI- take images of the brain interior
CT- X-ray images

Question 8

FMRI and PET

Answer 8

Functional
FMRI- shows brain activity by measuring oxygen consumption
PET- Scans in colour measure brain activity with glucose.

Question 9

what is CTE

Answer 9

CTE is a disease linked to repeated impacts to the brain from and external force.
