Ergonomic interface "Ribbon" similar to MS Office 2007/2010 interface allows forming command groups for implementation of EEG-studies according to purchased software and assigned tasks.

Basic components of the main window: 1. Heading. 2. File manager and Quick Access Bar. 3. RibbonUI with tabs where the commands are grouped. 4. Windows – one of the additional EEG applications. 5. Vertical tab for temporarily minimized active window. 6. Signal window with amplitude-time grid. 7. Channels panel - tracks. 8. Context menu. 9. Status bar.

Recording and visualization with high resolution of up to 64 digital EEG derivations, software control of phono- and photostimulation.

Channels configuration (up to 45) includes a list of types of channels and their quantity, as well as the signal filter settings individually for each channel (HPF, LPF, rejector).

EEG montages are stored in a special expandable library (over 40 montages). The montage editor allows changing the existing montages or creating new ones. Virtual (with the option of returning to initial state) montage changing is available both during EEG recording and analyzing.

The record scenario determines the sequence of hardware and software functional tests, as well as the configuration of stimulators.

Study profile library includes common profiles of the study carrying out, including the channels configurations, the montage and record scenario. There is an option of changing profiles and creating new ones.

Impedance and potentials (DCp) control during electrodes attachment. The values are recorded along with the EEG during real time record and used for subsequent analysis.

Using the "microscope" tool, you can view any signal zoomed in, measure its amplitude on selected fragment, and also estimate the frequency characteristics of a signal.

Manual and automatic setting of markers of various types while EEG recording, performing tests and subsequent analysis. Markers set during the study are displayed on a special list indicating the type and time of setting. The selection of the marker allows the user to visualize the corresponding fragment for analysis.

Split mode (splitting screen into 2 or more parts) allows viewing data of one study (the one part may demonstrate the current record process, the other one – previously recorded EEG), or several studies, including an option of presenting results and their math analysis in various forms.

The application supports 2 or more monitors, which allows distributing visual information in the most optimal way for effective EEG study. The main monitor displays native signals, others – results of math analysis in different forms, trends, video from cameras (up to 4), etc.

EEG study carrying out control from a remote computer via Ethernet.

For EEG analysis, the most common mathematical treatments are applied: power, amplitude spectrum; cross-spectrum, coherence function, auto- and crosscorrelation with the formation of the tables of quantitative parameters and topographic mapping.

Mathematical processing can be performed for the selected EEG fragments of various duration or required frequency range.

Automatic detection and marking of fragments of non-stationarities or epileptiform activity are performed during recording and EEG processing. Detected fragments are highlighted, saved and available for quick search for expert evaluation.

Record of ECG, EOG and EMG simultaneously with EEG provides automatic suppression of possible artifacts associated with cardio signal, eye movements and muscle activity.

Automatic report generation, based on the description of the selected background fragment and comparison of its characteristics with the selected EEG fragments. There is an option of editing the report and forming neurophysiological conclusion using the function of built-in text editor and a glossary containing common phrases used by a doctor.

Report editor

EEG print options
Convenient preparation and printing of informative EEG fragments, results of processing in tables and graphs, conclusions on a study with a special Print Manager tool.

EEG records storage
Storage of studies in a database "Cardfile" with a option of export and import of studies, and archiving of data on a variety of external media. There is an option of arrangement of the "Cardfile" database in the network on a dedicated server.

Viewing study results on any computer (without installed "Encephalan" software)
Specialized application "Encephalan-EEG-Viewer" is uploaded onto any external data storage in addition to recorded EEG study for results exchange among specialists and to hand out the results to the patient in order to get an independent medical consultation or prepare presentations and reports, and provides the basic functions for visual analysis of EEG (viewing data, reference reconstruction, scaling and selecting of EEG signals) on any computer.

There is an option of creation videos with informative fragments of the study (in common *.avi format), which can be viewed by standard players such as Windows Media or CD/DVD-player.

Software "Encephalan-EEGR" is compatible with another additional software, that expands its capabilities.

"Encephalan-MPA" software for multiparameter analysis of signals from polygraphical channels in combination with EEG signals (patent RF 2252692) provides calculation and visualization of trends, which display cardio-cyclic dynamics (averaging from cycle to cycle) of different physiological parameters of cardio-vascular, vegetative and central nervous systems, which provides visual evaluation of their interconnection.

Videomonitoring kit for EEG/PSG-video and software "Encephalan-Video" provide completely synchronized continuous digital record of EEG, audio- and video data, event marks, analysis and archiving of these data for differential diagnostics of epilepsy.

"Encephalan-EP" software for EP-studies – studies of long-latency visual and auditory evoked potentials, somato-sensory, MMN, CNV, P300 and visual EP for chess pattern.

"Encephalan-AVS" software suite for EEG and EP studies using audiovisual stimulation uses different scenarios of cognitive stimulation. Sub-sensory (unconscious) stimuli presentation with masking and response control is available.

"Encephalan-3D" software for 3D localization of the electrical activity sources 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.

"Encephalan-VLFA" software for analysis of very low frequency activity (patent RF 2252692). Trends of very 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 maps by calculating the reciprocal functions (cross-correlation, cross-spectrum, coherence function) for the diagnosis of inter-and intracortical violations, detection of pathological activity, treatment monitoring, studying topical peculiarities and intra interaction while doing different activities.

"HRV" software for heart rate variability analysis for evaluation of VNS and neurohumoral regulation of a patient in initial (background) state and considering vegetative response to provoking actions.
