Experiencing visuo-motor plasticity by prism adaptation in a classroom setting

Area of Science:

• Behavioral Neuroscience
• Motor Control
• Neuroplasticity

Background:

• Neural plasticity is fundamental to behavioral neuroscience but challenging to demonstrate.
• Visuo-motor plasticity, the brain's ability to adapt motor coordination to visual input changes, is a key area of study.

Purpose of the Study:

• To present an interactive laboratory technique for demonstrating and quantifying visuo-motor plasticity.
• To provide a practical classroom method for illustrating neural adaptation.

Main Methods:

• Utilizing horizontally-displacing prism goggles to alter visual input.
• Measuring motor coordination accuracy before, during, and after adaptation tasks.
• Quantifying adaptation through negative aftereffects upon goggle removal.

Main Results:

• Initial motor coordination is inaccurate with prism goggles.
• Performing visuo-motor tasks leads to significant adaptation and improved coordination.
• A robust negative aftereffect is consistently observed after adaptation, usable for quantification.

Conclusions:

• The described technique effectively demonstrates and quantifies visuo-motor plasticity in a laboratory setting.
• Active adaptation conditions are more effective than passive ones for inducing plasticity.
• This method offers a valuable tool for teaching neural plasticity concepts.
