Transcranial Direct Current Stimulation in Post-Stroke Aphasia Rehabilitation: Bilateral vs Unilateral Online Stimulation
2017
Here we aim to evaluate the efficacy of repeated sessions of transcranial Direct Current Stimulation (tDCS) as additional treatment to standard behavioural rehabilitation in post-stroke aphasic patients comparing bilateral with unilateral left-sided and sham-tDCS. Background: Aphasia is the most common post-stroke cognitive disorder and it severely impacts activities of daily living and social interactions. tDCS recently showed good results in post-stroke aphasia rehabilitiation, even if no agreement at now exists about the stimulation parameters to employ to achieve the best rehabilitative outcome. Design/Methods: We enrolled twenty-two patients with single left-brain lesion at CT or MRI s…
The default mode network and the working memory network are not anti-correlated during all phases of a working memory task
2015
INTRODUCTION:\ud \ud The default mode network and the working memory network are known to be anti-correlated during sustained cognitive processing, in a load-dependent manner. We hypothesized that functional connectivity among nodes of the two networks could be dynamically modulated by task phases across time.\ud METHODS:\ud \ud To address the dynamic links between default mode network and the working memory network, we used a delayed visuo-spatial working memory paradigm, which allowed us to separate three different phases of working memory (encoding, maintenance, and retrieval), and analyzed the functional connectivity during each phase within and between the default mode network and the …
