Investigating Transcranial Direct Current Stimulation (tDCS) in Accelerating Learning in a Healthy Older Population

Investigating Transcranial Direct Current Stimulation (tDCS) in Accelerating Learning in a Healthy Older Population

The overall objective of this study is to explore whether transcranial Direct Current Stimulation (tDCS) can accelerate associative learning and boost associative memory in healthy subjects.

The overall objective of this study is to explore whether transcranial Direct Current Stimulation (tDCS) can accelerate associative learning and boost associative memory in healthy subjects.

The aim of this study is to investigate the effects of transcranial Direct Current Stimulation (tDCS) stimulation during a verbal paired-associate learning task to determine if tDCS may be used as a way to enhance brain plasticity during an associative memory task, and to accelerate learning and to optimize associative memory performance. We hypothesize that participants who receive tDCS stimulation will improve their associative memory performance.
