Published	04/01/2024	{{c1::Montages}} are specific arrangements of channels; a channel is a {{c1::pair}} of electrodes
Published	04/01/2024	bipolar montages are less prone to {{c1::artifact}} and best appreciate {{c2::focal potentials}}
Published	04/01/2024	A {{c2::sizable area of cortex}} is required to generate enough signal on scalp recordings. {{c1::Small potentials}} may be missed.
Published	04/01/2024	In a referential recording, the record the potential difference between a particular scalp electrode and the {{c1::referential}} electrode.
Published	04/01/2024	delta waves in an awake individual imply {{c1::cerebral dysfunction}}
Published	04/01/2024	Excessive diffuse {{c1::delta:: wave type}} is abnormal and indicates {{c2::encephalopathy of non-specific etiology}}.
Published	04/01/2024	Focal rhythmic {{c1::delta}} activity can involve the ipsilateralgray matter and be indicative of underlying {{c2::cerebral hyperexcitability}}.
Published	04/01/2024	Slow wave sleep (SWS): There is an increased amount of {{c1::diffuse delta}} activity and decreased {{c2::sleep spindles}}
Published	04/01/2024	{{c2::Rapid eye movement (REM)}} sleep. Note the irregular, fast, horizontal eye movements. They sometimes seem spiky, which represents artifacts of t…
Published	04/01/2024	Photic stimulation (PS) is another standard procedure during routine EEG recording. The procedure is easily carried out with strobe units that flash f…
Published	04/01/2024	Left superior temporal gyrus lesion leads to what? {{c1::Wernicke's aphasia}}What other cortex is there? {{c1::also contains primary auditory cortex}}
