Polarity-dependent cerebellar transcranial direct current stimulation modulates online functions of the alerting attention network.

Objectives: To investigate the modulatory effect of anodal, cathodal and sham cerebellar transcranial direct current stimulation (ctDCS) on the efficiency of the 3 attention networks namely alerting network, orienting network, and the network of executive control.

Methods: A sham-controlled, single-blind study. Experiments were performed at the neuroscience lab of Imam Abdulrahman Bin Faisal University, Dammam, Kingdom of Saudi Arabia, between the months of January-July of 2018.

Online polarity-dependent effects of cerebellar transcranial direct current stimulation on motor speed and fine manual dexterity. A randomized controlled trial.

To investigate the role of cerebellar transcranial direct current stimulation (ctDCS) in modulating cerebellar functions in the motor domains of fine motor dexterity and motor speed. Methods: A single-blind, randomized sham-controlled study was conducted between January and July 2018 at the neuroscience laboratory of Imam Abdulrahman Bin Faisal University. A total of 63 healthy participants were assessed for eligibility.
