Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	A Computerized Verbal Paired-associate Memory Task Will be Used to Assess Memory Performance.	Memory performance scores recorded in the computerized verbal paired-associate memory test during each visit will be compared between the two groups (active tDCS and sham tDCS).	Memory performance changes will be assessed in two different visits. First assessment (baseline) on visit 1 (learning), then one-week after during visit 2 (memory)
