acquisition & analysis of neurologic dataemka TECHNOLOGIES provides smart solutions for acquisitionand analysis of neurologic and other physiologic datarodent EEG telemetrywireless, low cost, head-mounted eeg for ratsrodentPACK is a wireless, head-mounted telemetrysystem for rodents. It enables the acquisition of EEGand other biopotential signals, as well as activity/positional data - applications are varied, e.g. sleepand epilepsy studies, ECG recordingrodentPACK transmits data via radiotelemetry,offering a well-tolerated, humane alternative totethered EEG. Direct inputs from the device tocortical and deep brain regions provide a high signalto noise ratio, facilitating the detection of EEG events. rodentPACK head-mounted transmitterrodentPACK consists of: » skull connector permanently implanted » transmitter, connected to skull implant only during recordings » receiver with antenna8 signals are acquired for each rodentPACK » 4 biopotential signals each sampled at 1 kHz › 4 EEG › or 3 EEG + 1 ECG/EMG › or 2 EEG + 2 ECG/EMG » 3-axis acceleration, sampled at 25Hz on each axis » global acceleration (computed from 3 axes), for activity assessment rodentPACK skull connector closeupkey features » measures 19.5 x 25 x 18 mm advantages (transmitter and skull connector) » compact, light and noise free transmitter » and weighs 13 g: ideal for rats » no refurbishment, batteries cost » transmission range: up to 5 m less than 2$/recording » 70 hours of continuous transmission » same transmitter may be used on any implanted animal » group housing with multiple animals in same cage » x/y/z acceleration signals allow » 20 to 40 animals in same room for postural information with no required shielding » total acceleration useful for validating events » rodentPACK may be fixed to the cranium on eeg/emg traces (seizure, movement) or used as a transmitter alone » rapid acclimation to rodentPACK: » iox software for acquisition, analysis rats are not restrained in their activities and synchronized video recording » open system with analog outputs » ecgAUTO software for advanced analysis for direct connection to any software (ECG, FFT, sleep scoring)emka TECHNOLOGIES

CNS analysis softwareEEG analyzer module within ecgAUTO software*power spectrum analysisThe software allows the scientist to easily generatefft power spectrums with user defined frequencybands. » power in up to 6 adjustable frequency ranges » absolute and relative power values » versatile scheduling of analysis, epoch lengths, overlap factor, windowingsleep scoringOur high throughput, automated sleep scoringmodule differentiates between four sleep stages and ecgAUTO 3-D display of average spectrums over timecalculates global sleep scores. » define threshold values applicable to any parameter from any input » software applies logical rules to attribute 1 out of 4 sleep stages to each epoch » trend graph displays parameters as well as sleep stages » user may, on the fly, adjust thresholds and see the effect on sleep scoringOptional video for confirmation of sleep score ecgAUTO epoch power spectrum (EEG analyzer)and classification of seizure type is also available.Analysis of SNA and peripheral nerve data featuresoriginal and integrated outputs, and user-definedamplitude thresholds and refractory periods.epilepsy seizure detectionThe EEG analyzer module can also be used to detectepilepsy seizures from EEG traces » automatic software seizures detection is performed using combined analysis of various parameters ecgAUTO sleep scoring module. from top: cortex, hip- » all detected seizures are logged in a table pocampus, muscle, sleep score, active wake, quiet wake, REM sleep, SW sleep » manual edition of seizures limits is possible » invalid seizures can be deleted » undetected seizures can be created » valid seizures can be exported to text file*Concurrent ECG, hemodynamic, or pulmonary data analysis is also available. 4 epilepsy seizures detected (EEG acquired with rodentPACK) www.emka.fr
