How It Works
Transcranial direct current stimulation works by sending constant, low direct current through the electrodes. When these electrodes are placed in the region of interest, the current induces intracerebral current flow. This current flow then either increases or decreases the neuronal excitability in the specific area being stimulated based on which type of stimulation is being used. This change of neuronal excitability leads to alteration of brain function, which can be used in various therapies as well as to provide more information about the functioning of the human brain.

Famous quotes containing the word works:
“Again we mistook a little rocky islet seen through the “drisk,” with some taller bare trunks or stumps on it, for the steamer with its smoke-pipes, but as it had not changed its position after half an hour, we were undeceived. So much do the works of man resemble the works of nature. A moose might mistake a steamer for a floating isle, and not be scared till he heard its puffing or its whistle.”
—Henry David Thoreau (1817–1862)
