Document Summary
Electrical recording methods detect changes in the electrical activity of neurons. Brain stimulation methods include changes in the electrical activity of the brain. X-ray imaging methods are sensitive to the density of different parts of the brain, the ventricles, nuclei, and pathways. Dynamic imaging methods record and manipulate ongoing changes in brain activity, including the electrical activity of cells, biochemical events, differences in glucose consumption, and the flow of blood to various regions. Nerve cells have an electrochemical basis and can therefore be recorded with instruments sensitive to small changes in electrical activity. Single-cell recording confirm this hypothesis: single-cell recording at these different levels show that ganglion cells and. The two electrodes detect the difference in the electrical potentials. The duration of an epileptic attack correlates closely with the duration of abnormalities in the eeg, which may consist of a loss of recording a slowing of recording, or large distinctive spikes.
