USB Data Acquisition

The USB-ME-Systems fulfi ll three

functions in one device:

• Data acquisition from 64, 128 or

256 channels.

• Controlling and synchronization

of other devices with TTL pulses.

• Online and offl ine analysis

through included software.

The USB-ME-System is a complete

plug-and-play data acquisition

system based on signal processor

technology.

Take your advantage of the plug-and-play

capabilities of USB:

• Easy experimental setup

• Use any desktop PC or notebook

• Portable system for use in more than one

setup

Depending on the number of channels,

you can connect one, two or four

amplifi ers at the same time running

different experiments on each of them.

Open the data acquisition and analysis

software up to four times at once and

control your amplifi ers independently.

It doesn’t matter if you want to record

in vivo or if you use our in vitro-solution

(MEA-System) measurements.

Everything is possible from 64 up to

256 channels. Besides of that you can

synchronize more than one USB-System

to record from an even higher number of

channels.

64 and 128 channel data acquisition

256 channel data acquisition

Perfect integration into your setupOn 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 amplifi ed 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 softwareThe 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_RackYou 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_RackDon’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 feedbackBy 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.

The schematic view shows the principle

of operation:

The DSP detects spikes/signals in the

filtered data from each channel. You

can define the criteria and time frame

for the feedback. If your criteria apply,

a digital output is generated, which can

be used to trigger a stimulus generator

or other external devices.

MC_Rack export featuresYou 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 NeuroExplorerThis 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.
