What is "myelin"?

• A type of fatty substance covering the arteries

• A type of nerve cell found in the human brain

• A type of fatty substance that is only present in the prefrontal cortex

• A fatty substance that covers and insulates nerve fibers

What is meant by "mental image"?

• It is something that is not real or present and is produced by memory or imagination

• An image that is presented to patients during a brain scan

• An image added to the brain and is part of a thought process

• An image that the brain processes after seeing something

What is a "neuronal ensemble"?

• Synchronous firing strengthens the neurons and they become attached to one another creating a neuronal cell link

• Synchronous firing weakens the connections between set of neurons, separating them into different forms of neuronal connections

• Asynchronous (not synchronous) firing strengthens the connections between set of neurons, linking them together

• Synchronous firing strengthens the connections between set of neurons, linking them together

What is the cerebral cortex?

• The area of the brain that regulates body temperature and hunger
• The layer of the brain responsible for processing visual information
• The outer layer of the brain responsible for higher brain functions
• The part of the brain that controls breathing and heart rate

What is meant by "synchronisation"?

• Synchronisation happens when the myelin works together with the nerve cells

• Synchronisation refers to the neurons working together after a mental image appears

• Synchronisation refers to the neurons working randomly

• Synchronisation refers to the neurons working together to make images

What is the prefrontal cortex responsible for?

• Decision making, social behaviour and planning

• Motor coordination, balance and body image

• Visual processing and perception
• Digestion and metabolism

What is an "axon"?

• A long, slender projection of the posterior cortex

• A long, thread-like structure attached to a nerve cell that sends out signals away from the nerve cell

• It is part of a neuron and is responsible to attach neurons to the neuro fibres

• It is a long and thin tube that is part of the prefrontal cortex

What is the process of myelination and when does most of it happen?

• Breaking down of myelin around nerve cell axons and it happens during adulthood

• Formation of myelin around bone cell axons and it happens during childhood

• Expansion of myelin around muscle cell axons and it happens during childhood

• Formation of myelin around nerve cell axons and it happens during childhood

What is a neuron?

• It is the other name for myelin

• The other name for blood cells

• It is a nerve cell

• It is a nerve and a bone cell together

What is the Hebbian principle?

• Different images are coded in a different neuronal ensemble

• The principle that underlies the firing of neurons in the spinal cord

• Cells that fire together, wire together
• Neurons charged in an opposite way (negative and positive) attract each other
