Neurobiology Imaging Service—HIGH-DENSITY EEG/256 Channels (Electrical Geodesics)

Neuroscience is a multidisciplinary field involving the study of the structure and function of the nervous system. It aims to understand the development of cognitive and behavioral processes, as well as to understand various diseases (such as Alzheimer's or Parkinson's disease) and find treatments for them. Neuroscientists often need to use microscopy to study challenging and complex samples to better understand the nervous system. CD BioSciences offers a comprehensive range of HIGH-DENSITY EEG/256 Channels (Electrical Geodesics)-based imaging solutions to enable you to overcome these challenges.

HIGH-DENSITY EEG/256 Channels (Electrical Geodesics)

Introduction

METHODS & EXPERTISE FOR RESEARCH INFRASTRUCTURE
The main scientific application is in 3 areas:
1. Application for long-term admissions in sleep-disturbed (insomnia) patients
2. Use in adults and newborns for the registration of EEG/ECG/EMG data after acoustic stimulus performance
3. Recordings during sleep in healthy subjects and research on the topic of "learning during sleep" as well as
4. Evaluation of residual cognitive skills as well as sleep and wakefulness in post-comatose patients.
The methodological expertise lies in the field of sleep classification, as well as time-frequency research by means of wavelet analyses, phase calculations (PLI, PLV) or classic ERP analyses.

Technical Services

EEG acquisition of projects related to'learning during sleep' (i.e., memory consolidation across sleep)
Information processing of auditory stimuli presented during sleep
"Baby EEG" right after birth as well as in toddlers
Recording of long-term polysomnography in patients who had a severe brain injury (VS/UWS and MCS) in to improve diagnostic and potentially also assist prognostic statements

Summary

256-channel "high-density" EEG with PhysioBox for external sensors as they are necessary for long-term recordings (e.g. of sleep). The Electrical Geodesic hdEEG system allows the simultaneous recording of 256 EEG channels as well as additional physiological channels such as eye activity, muscle activity or respiratory signals. The device has eeg caps that can be attached particularly quickly (for short-term recordings of about 1 hour) as well as special "gel-based" nets for long-term recording. The short-term nets are also available in small sizes, such as those needed for recordings in newborns and toddlers.
Visual and auditory stimulus performance takes place via separate laptops and is simultaneously fed into the EEG signal as a "trigger". Ambulatory (IR) cameras allow the recording of videos simultaneously to hdEEG recording. In addition to 3 stationary 32-channel EEG amplifiers (BrainAmp 32), the Core Facility EEG also includes 3× outpatient AlphaTrace EEG devices and 7× Becker Va

CD BioSciences' solutions can combine high resolution, deep imaging, and large section display to give you the flexibility to image different types of samples such as live cells, tissues, organoids, and model organisms. If this is of interest to you, please contact us directly.
