19 or 21-channel (up to 64 digital derivations) electroencephalographs-analyzers EEGA-21/26 "Encephalan-131-03" are an effective and reliable tool for classic electroencephalography at stationary use.

·         Multichannel computerized complexes with mapping for electroencephalography, REG and evoked potentials study:

modification 08: 19 EEG channels + 6 REG channels + 1 polygraphic channel (ECG);

modification 10: 21 EEG channels + 6 REG channels + 4 polygraphic channels + 1 additional channel.

·         Multichannel computerized complexe with mapping for electroencephalography and evoked potentials study:

modification 11: 21 EEG channels + 4 polygraphic channels +1 additional channel.

A unique option of synchronized EEG and REG study (modifications 08 and 10) provides new diagnostic information about the relationship of brain activity and cerebral blood flow for considering vascular factor in epilepsy, for diagnostics of syncopal states and cerebrovascular disorders at hyperventilation functional tests, and also reduces the total study time.

Phono-, photostimulation and chess pattern stimulation for EP studies during EEG studies. Patient button unit for cognitive EP study (MMN, CNV, P300).

"Optimal", "professional" and "elite" software suits provide a wide range of functionality for EEG analysis for any application. Optional software extends the functionality of electroencephalograph.

Additional functional capabilities:

• EEG/PSG Videomoitoring kit and software “Encep­halan-Video” for completely      synchronized continuous digital record of electroencephalogram, audio- and      video information, events marks, and for their analysis and archiving for      differential epilepsy diagnostics.
• EP-studies  “Encephalan-EP” – studies of long-latency visual and auditory evoked      potetials, somatosensory, MMN, CNV, P300, and visual EP for chess pattern.
• Software      “Encephalan-AVS” for EEG and EP studies with audio-visual stimulation uses      different scenarios of cognitive stimulation. There is an option of      sub-sensory (unconscious) stimuli presentation with marking and response      control.
• 3D  localization of electric activity sources “Encep­halan-3D” provides      display of nominal source of electric activity on three projections of      brain cut in the form of spatial dipole cloud, which allows localizing      focus of EEG epileptiform activity or EP components source.
• Analysis      of super slow brain activity synchro­nously with EEG recording      “Encephalan-SSA” (patent RF 2252692). Trends of super slow potentials      dynamics and topographic maps of instant values and reactive changes of      DC-potentials' level to functional tests carried out allow evaluating      indirectly the cerebral energy exchange and metabolic  changes dynamics.

• Analysis      of functional brain asymmetry “Encephalan-FBA” provides visualization of      intercentral connections map basing on the calculation of mutual functions      (cross-correlation, cross-spectrum, coherence function) in order to      diagnose inter- and intracentral interaction during different types of      action.

• Heart rate variability analysis “HRV” for evaluation of VNS and neurohumoral regulation of a patient in initial (background) state and considering vegetative response to provoking actions. Provides the evaluation of adequacy of physical and psycho-emotional stresses, and drugs effect and treatment efficiency control.
