Which daily action burns up a large majority of calories expended daily?
Just staying alive
Which are the 2 most metabolically expensive organs in the body?
Brain and liver
Which percentage of energy use does the brain use?
Roughly 20%
Which percentage of the body mass does the brain take up?
Roughly 2%
Which proportion of your resting metabolic rate goes on in the brain?
1/5
How many kw/h does 1/5 of the brains resting metabolic rate equate to per day for an average person?
0.3 kw/h
List an important adaptation of the brain for energy use
Energy efficient coding strategies
Explain the energy-efficient coding strategy in the cerebellum
The responsibility for motor control is gradually delegated to the cerebellum as opposed to using large portions of the brain to continually regulate action
Which percent of cardiac output goes to the brain?
15%
Which percent of total VO2 goes to the brain?
20%
Which percent of total glucose use goes to the brain and why?
15%, the brain is a very hungry organ and needs to be fed continually
What is the brains key source of energy?
Glucose
What are the 2 other sources of energy the brain uses for fuel?
Ketones and lactate
Which 5 main things are increased in the brain acutely/short term when exercising?
Brain blood flow
Sleep quality
Metabolism
Brain temp
Dopamine/serotonin
What is often the cause of people stopping exercising or reducing the intensity of their exercise?
When you reach near exhaustion and the brain temp reaches a threshold where you can not continue on
What can increased blood flow improve?
Blood oxygenation
How come exercise if oftwen used to treat depression, anxiety and other depressive orders?
Because during exercise, cortisol the stress hormone is decreased overtime
Provide an example of a sensorimotor representation
Doing alot of certain type of exercise and using a certain part of your body eg in table tennis you use your right arm alo0t so your brain representation of your right arm is likely to become more bigger and more concentrated
Define neural plasticity
The brains ability to learn continuously through the lifespan
Around what age is the greatest rate of neuroplasticity?
0-5 years
What is synaptic pruning?
Getting rid of some connections
At which stage in life is synaptic pruning most important for?
Early on in life
What is myelination and what is it important for?
It is important for learning as it enables signals to be passed more faster in effect
