In medicine (oncology and other fields), performance status is an attempt to quantify cancer patients' general well-being and activities of daily life. This measure is used to determine whether they can receive chemotherapy, whether dose adjustment is necessary, and as a measure for the required intensity of palliative care.
Electrocorticography (ECoG), a type of intracranial electroencephalography (iEEG), is a type of electrophysiological monitoring that uses electrodes placed directly on the exposed surface of the brain to record electrical activity from the cerebral cortex.
The Eastern Cooperative Oncology Group (ECOG) began in 1955 as one of the first publicly funded cooperative groups to perform multi-center clinical trials for cancer research. [1] A cooperative group in oncology constitutes a large network of private and public medical institutions developing protocols for cancer treatments. Institutional ...
1 point: Age 50–59, LDH 0.67-0.99 of the upper limit of normal, or WBC 6,700 to 9,999 cells/mcl; 2 points: Age 60–69, ECOG performance status of 2–4, LDH 1-1.49 times the upper limit of normal, or WBC 10,000-14,000 cells/mcl; 3 points: Age 70 or greater, LDH 1.5 times the upper limit of normal or greater, and WBC of 15,000 cells/mcl or ...
Electrocochleography (abbreviated ECochG or ECOG) is a technique of recording electrical potentials generated in the inner ear and auditory nerve in response to sound stimulation, using an electrode placed in the ear canal or tympanic membrane. [1]
Cortico-cortical coherence is commonly studied using bipolar channels of EEG recordings, as well as unipolar channels of EEG or MEG signals; however, unipolar channels are usually used to estimate the brain sources and their connectivity, using electrical source imaging and connectivity analysis.
Electrocorticography (ECoG) records the cumulative activity of hundreds to thousands of neurons with a sheet of electrodes placed directly on the surface of the brain. In addition to requiring surgery and having low resolution, the ECoG device is wired, meaning the scalp cannot be completely closed, increasing the risk of infection.
