The temporal and spatial resolutions and signal to noise ratios of EEG have always lagged behind those of comparable intracortical devices, but it has the advantage of not requiring surgery.

Later work done by Phillip Kennedy and colleagues built the first intracortical brain computer interface by implanting neurotrophic-cone electrodes into one man, Johnny Ray, a stroke victim unable to move muscles below his face.

In contrast to the situation in rats, where long periods of theta oscillations are easily observed using electrodes implanted at many sites, theta has been difficult to pin down in primates, even when intracortical electrodes have been available.

"' Intracortical encephalogram signal analysis "'( "'minedICE "') is the learning and subsequent prediction of electrical activity inside the grey matter of the brain produced by the firing of neurons within the brain.

Staining cross-sections of the cortex to reveal the position of neuronal cell bodies and the intracortical axon tracts allowed neuroanatomists in the early 20th century to produce a detailed description of the " laminar structure of the cortex " in different species.

Others classify them as hippocampal, cortical, and WM lesions, and finally, others give seven areas : intracortical, mixed white matter-gray matter, juxtacortical, deep gray matter, periventricular white matter, deep white matter, and infratentorial lesions.

Lesions in the cortex have been classified by the area they affect into four groups : type I ( leukocortical ), type II ( intracortical ), type III ( subpial ), and type IV ( subpial extending through the whole cortical width but not to subcortical WM ).

Intracortical encephalogram signal analysis has two components : 1 ) an intracortical EEG multicontact electrode ( "'ICE "') that inserted through a patient's skull and deep into the grey matter of the patient, and 2 ) an artificial intelligent agent that is trained in neurological signal analysis.

ECoG is a very promising intermediate BCI modality because it has higher spatial resolution, better signal-to-noise ratio, wider frequency range, and less training requirements than scalp-recorded EEG, and at the same time has lower technical difficulty, lower clinical risk, and probably superior long-term stability than intracortical single-neuron recording.
