Neuroplasticity part 2

Front

What is neuroplasticity?

Back

Neuroplasticity is the brain's ability to reorganize itself by forming new neural connections throughout life, allowing it to adapt to new experiences, learn new information, and recover from injuries.

Front

What is a restorative mechanism in neuroplasticity?

Back

A restorative mechanism refers to the processes by which neural tissue nearby an injury takes over identical neural functions to recover lost capabilities.

Front

What is denervation super-sensitivity?

Back

Denervation super-sensitivity is an intercellular response to injury where the postsynaptic membrane becomes hyperactive to neurotransmitters due to the loss of presynaptic input.

Front

What happens to cortical maps following a peripheral lesion such as amputation?

Back

Following a peripheral lesion, nearby cortical maps can expand their fields to cover the denervated area, demonstrating cortical remapping.

Front

How does the cortical representation of the body change in healthy adults?

Back

The cortical representation of the body is continuously modified in healthy adults in response to activity and skill, reflecting the brain's adaptability.

Front

What role does experience play in neuroplasticity?

Back

Experience plays a crucial role in neuroplasticity, as engaging in new activities or learning new skills can lead to structural and functional changes in the brain.

Front

What is the significance of synaptic plasticity in learning?

Back

Synaptic plasticity, the ability of synapses to strengthen or weaken over time, is fundamental for learning and memory, allowing for the encoding of new information.

Front

What is the difference between structural and functional plasticity?

Back

Structural plasticity refers to the physical changes in the brain's structure, while functional plasticity refers to the brain's ability to move functions from damaged areas to undamaged areas.

Front

What is the impact of age on neuroplasticity?

Back

While neuroplasticity occurs throughout life, it is generally more pronounced in younger individuals, with a gradual decline in plasticity observed as age increases.

Front

How can neuroplasticity be harnessed in rehabilitation?

Back

Neuroplasticity can be harnessed in rehabilitation by using targeted therapies and exercises that promote the reorganization of neural pathways to recover lost functions.
