Understanding Neuroplasticity

What is neuroplasticity?

• the ability within the brain to constantly change the structure and function of neurons in response to experience or trauma

• the reduction of synapses through a "use it or lose it" process

• the idea that different areas of the brain perform differing functions

• Using magnetic technology to measure blood flow to different parts of the brain, to study it more effectively

Synaptic connections between neurons are strengthened by repeated use (or excitation), which is the process described by which concept below?

• Localization of function

• Neurogenesis

• Long Term Potentiation (LTP)

• Neural pruning

Groups of interconnected neurons that work together to process information are . . .

• Neuroplasticity itself

• Neural networks

• Neural pruning

• Localization of function

Which of the following occurs as Long-Term Potentiation builds and strengthens neural networks in the brain?

• Engulfment by microglial cells

• Dendritic branching

• Synaptic pruning

• None of the above

This image is an example of . . .

• Dendritic arborization (or dendritic arbor)

• Engulfment

• Neurogenesis alone

• Synaptic pruning

A key aspect of Neuroplasticity is neurogenesis, which can be defined as . . .

• When neurons communicate with one another across synapses

• The process by which underused or unneeded synapses are "engulfed" and pruned

• The process by which new neurons are formed in the brain

• When dendrites branch out so much that they appear like a tree

Which of the following best describes neural pruning?

• Groups of interconnected neurons that work together to process information

• The brain's ability to adapt to new experiences, learning and injury

• A machine that can help researchers to study brain structure and neural density

• The process of eliminating connections between neurons that are underused or no longer needed

What is the result of pruning in the brain?

• Decreased brain efficiency

• Increased memory loss

• Improved brain efficiency by eliminating unnecessary connections

• Growth of new neurons.

How does pruning affect the remaining connections in the brain?

• It weakens them

• It strengthens them

• It has no effect

• It eliminates them.

Which types of cells carry out the neural pruning process?

• Neurons

• White blood cells

• Hormone cells

• Microglial cells
