This project focuses on the combination of tDCS (transcranial direct current stimulation) with cognitive training (CT) to investigate neuroplasticity in older adults and further explore the involvement of the cerebellar cortex in memory processes. In particular, we are interested in understanding whether and how tDCS combined with cognitive training facilitates verbal episodic memory in older adults, compared with sham stimulation. We used an innovative design to further explore the synergetic effects of CT combined with tDCS. Specifically, we tested whether CT and excitatory tDCS over the left dorsolateral prefrontal cortex (lDLPFC) or right cerebellar cortex (rCC) facilitates verbal episodic memory, compared with sham stimulation and a wait list control group. CT was applied daily for 1 hour, after 20 minutes of tDCS, over 12 sessions. Performance on memory and other cognitive tasks was evaluated at baseline and post-intervention, using behavioral and neuroimaging tools. Participants were healthy elderly, ≥ 60 years, right handed, without history of neuropsychiatric disease.
