It is well recognized that the number and effectiveness of synapses in the adult brain change in response to learning and that similar processes contribute to the restoration of function after central nervous system damage. It is possible to use non-invasive methods of brain stimulation in humans (transcranial magnetic stimulation or transcranial direct current stimulation) to study and even ma...

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique. Because of its low cost, ease of use, safety, and portability, tDCS has been increasingly investigated for therapeutic purposes in neuropsychiatric disorders and in experimental neuropsychological studies with healthy volunteers. These experiments on healthy cognition have shown significant effects on w...

Insomnia is a sleep disorder that, in the case of primary insomnia, is due to alterations in the neural mechanisms of sleep. In addition, insomnia may be secondary to other diseases or to psychological or physical stress, or may appear as a side effect of different pharmacological agents. Considering that pathologically altered cortical activity can lead to insomnia, neuromodulation via non-inv...

Cortical excitability of the human brain can be increased or decreased using brain stimulation techniques. One of the methods currently used for that purpose is weak transcranial direct current stimulation (tDCS). This portable, non-expensive and non-invasive technique has recently received new interest in the field and has given promising results mainly in clinical neuropsychiatric and stroke ...

Transcranial direct current stimulation (tDCS) has recently emerged as a promising approach to enhance neurorehabilitative outcomes. However, little is known about how the local electrical field generated by tDCS relates to underlying neuroplastic changes and behavior. To address this question, we present a case study analysis of an individual with hemianopia due to stroke and who benefited fro...

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that has been investigated for the treatment of many neurological or neuropsychiatric disorders. Its main effect is to modulate the cortical excitability depending on the polarity of the current applied. However, understanding the mechanisms by which these modulations are induced and persist is still an ...

Electricity loads in buildings are increasingly supplied by distributed renewable generation sources such as photovoltaic (PV) modules or fuel cells. Often these systems are combined with an electricity storage to raise the level of self-consumption in buildings and to reduce the load on the electric grid. PV production and battery storage are both inherently based on direct current (DC) power....
