The researchers used a flexible pad of electrodes called an electrocorticography
array, or ECoG, that rests on the brain's surface to tap on the signals, MIT Technology Review reports.
The other was an Australian cohort of 12 patients with focal epilepsy who had at least 30 recorded seizures in a study of an implanted electrocorticography
device that tracked them between 6 months and 3 years.
, or ECoG, systems are currently bulky but, by using flexible, biocompatible polymers, Muller hopes to create tiny chips and antennas that can wirelessly collect power and integrate seamlessly with the brain.
Neuroscientific evidence is garnered via use of a number of machines, including electroencephalography ("EEG"), electrocorticography
("ECoG"), and functional magnetic resonance imaging ("fMRI"), although still other machines are used.
With the current use of high gamma electrocorticography
, the inferior frontal gyrus of the dominant left hemisphere is demonstrated as being one of the most important brain regions for language processing .

Abbreviations ECoG - electrocorticography
FD - fractal dimension DC - direct current GABA-A - gamma-aminobutyric acid type A Changes in spontaneous activity during anesthesia and aluminium intoxication led to desynchronization of the rhythm and change in the balanced state.
