64 and 128 channel data acquisition
The USB-ME-System is a complete
plug-and-play data acquisition
system based on signal processor
256 channel data acquisition
technology.
Take your advantage of the plug-and-play
capabilities of USB:
•

channels.
It doesn’t matter if you want to record
Perfect integration into your setup
On the rear panel of the USB-ME-Systems you have additional
connectors:
•
Digital IN/ OUT: Control and synchronize other devices with TTL
pulses, like imaging
system, stimulus generator, patch clamp system, etc.
•
D0 Out and D0 In: Independent access from the Digital IN/OUT
connector with a Lemo
connector. Generate and accept TTL pulses.
•
AUDIO: Make electrical activity audible in real- time.
•
Analog Input A1 to A4: Additional analog inputs for additional
signals from external devices.
•
USB: Transfer the amplified and digitized data from all channels to
any connected computer or laptop via High Speed USB 2.0.
•
Ground: Additional ground, if necessary.
Flexible and easy to use software
The data acquisition and analysis program MC_Rack is highly
adaptable with essentially unlimited possibilities.
For routine lab work, the program is set up like an instrument rack
on a workbench:
•
Combine virtual instruments (e.g. oscilloscope, filter, spike
sorter, and many more).
•
Virtual instrument rack: Use task-oriented template racks or
design your own.
•
Select any permutation of data streams for displaying,
analyzing, exporting, etc.
•
Extract parameters like spike rates in online or offline analysis.
•
Apply several virtual filters with different cutoff frequencies
e.g. to separate spike activity from local field potentials.
Online features of MC_Rack
You can select any number of channels, record
unmodified raw data, filtered data, and/or spike cutouts.
The flexible data stream management makes all that
possible.
Online filtering, spike sorting, local field potential
(LFP) extraction, and triggering allow you to monitor
parameters during the running experiment and save
offline analysis time. And for ultimate experimental
control, you can integrate the program controls (DLL)
into your own custom software.
More flexibility is not possible.
Offline features of MC_Rack
Don’t miss anything - review the raw data and extract
additional parameters offline after the experiments. You
can adjust spike detection or analyzer settings and re-run
your experiment any number of times. Take the computer
performance to the limit and extract multiple parameters in
parallel, for example, signal rate, peak-peak amplitude, slope
10/90 % and more. Or separate different signal frequencies
by virtual filters and analyze them separately.
Real-time signal detection and feedback
By moving the analysis from the PC to the DSP (Digital Signal Processor) integrated
in the USB-ME-System hardware, a real-time signal detection/feedback is possible.
The real-time signal detection/feedback is an advantageous feature if you need fast
and predictable reactions related to recorded analog signals without time delay.

MC_Rack export features
You can easily export graphics as bitmap or ASCII directly from the
software to your presentation or spreadsheet. Or just pick your
favourite offline analysis tool. The data file format is compatible
with various programs, like NeuroExplorer and Spike 2.
MC_Rack also supports Neuroshare- a universal file format for data
recorded with electrophysiological methods as used e.g. by FIND (a
novel tool for spike data analysis - http://find.bccn.uni-freiburg.de).
As an additional tool you can use the powerful data file handling
of MC_DataTool: export raw data or spike cutouts from selected
channels of interest as Axon Binary File (*.abf), ASCII file (*txt), or
as binary file (*.raw).
Features of NeuroExplorer
This analysis software package is perfect
for statistical analysis of spike trains and
other event data. It features standard
histogram, raster, and correlational
analyses for both point events (e.g.
spikes, behavioral events) and continuous
variables (e.g. field potentials). You receive
truly editable graphics — you can add
labels, header, and footer to your data.
Just copy and paste graphics to any other
program. You can directly transfer the
results to Excel or to Matlab using COM
interface. All parameters and algorithms
are described in the comprehensible help.
There is also a powerful built-in scripting
engine to edit your data or simply to run
analyses in batch mode.
