To characterize the exchange of information within and between cortical regions, I will combine whole-brain magnetoencephalography of with invasive electrocorticography and intra-laminar recordings, acquired from patients implanted for clinical purposes.
brain use exclusively human-based research methods such as advanced brain-imaging and -recording techniques including electrocorticography (ECoG),(#_ftn17) [17] ,(#_ftn18) [18] positron emission tomography (PET), single photon emission computed tomography (SPECT),(#_ftn19) [19] functional magnetic resonanceA imagingA (fMRI)(#_ftn20) [20] , magnetic resonanceA imagingA (MRI), electroencephalography (EEG), intracranial electroencephalography (iEEG)(#_ftn21) [21] and computed tomography (CT).
A number of neural recording technologies are being investigated for BCI applications in humans, including scalp electroencephalography [18-20], electrocorticography [2125], and intracortical microelectrode recordings [26-30].
Sixteen channel electrocorticography was then positioned over the cortical surface and EEG recording was performed.
The approach is based on electrocorticography, or ECoG, a method used by doctors to detect electrical activity in the brain.
Among the aspects they discuss are magnetic stimulation, somatosensory evoked potential monitoring with scalp and cervical recording, electrocorticography and intraoperative electroencephalography, special considerations in pediatric surgical monitoring, the technique and protocol for monitoring selective dorsal rhizotomies, and the intraoperative wake-up test.
For the project, a BCI based on electrocorticography (ECoG) placed on the spinal cord injury will pick up neural activity and translate it through a computer processor, allowing the patient to learn to control computer cursors, virtual hands, computer games and assistive devices such as a prosthetic hand or a wheelchair.
Chapter topics covered include neurophysiologic tests used in the operating room, EEG monitoring during carotid endarterectomy, electrocorticography, monitoring and mapping of the spinal cord, monitoring of the cranial nerves and brainstem, and the effects of anesthetics on intraoperative neurophysiology studies.
