A-M Systems SciWorks Discovery software and advanced A/D hardware is the perfect complement to our low-channel count extracellular or intracellular amplifiers. It is designed to work with 1 to 8 single-ended channels of data. If you require more data processing capability, then consider our Discovery Pro system with more channels, optional video support, and a faster sampling rate. SciWorks Discovery is a real-time data acquisition, analysis, and instrument control application designed for a wide variety of electrophysiology experiments. It provides the user with a single interface to control instrumentation, perform real-time data analysis, including multi-unit spike sorting and separation, generate complicated stimulation patterns, and write data to a multiple of common industry-defined data formats.
Data acquisition and analysis processes are seamlessly integrated into a single software package. Users can define how the experiment should run, collect data, run complicated analysis tools, and store raw and analyzed data all at the same time—without having to change software packages.
Discovery can be paired with a BNC breakout box providing direct access to the most critical connections of the A/D card or a screw-terminal accessory for a less expensive solution.
See the A/D Hardware tab for additional information.
While SciWorks Discovery is the ideal data acquisition and analysis system for most electrophysiology experimental protocols, there are situations where upgrading to Sciworks Discovery Pro makes scientific and financial sense. If you are interested in acquiring and processing more than 8 channels of data, then upgrading to one of our SciWorks Discovery Pro options can give you access to up to 128 channels of capability. SciWorks Discovery’s underlying 8-channel data acquisition card’s clockrate is sufficient to generate simple stimuli. However, if your experimental protocols require delivering complicated stimulus trains, or auditory stimuli, then it is recommended to upgrade to SciWorks Discovery Pro. Finally, if your research protocols involve capturing, measuring, and analyzing video data, then SciWorks Discovery Pro with the optional VideoBench add-in is the software package to be used.
Upgrading to SciWorks Discovery Pro is also cost effective. While you can pay a price difference later to upgrade from the Discovery to the Discovery Pro software package, it is necessary to purchase the required a/d hardware that supports Discovery Pro at full price. Thus, purchasing Discovery Pro upfront means not double paying for acquisition hardware systems.
See the next tab for a comparison chart between the features of Discovery and Discovery Pro.

Additional information on the available tools can be found on the Acquisition tools tab.
While SciWorks Discovery is the ideal data acquisition and analysis system for most electrophysiology experimental protocols, upgrading to Sciworks Discovery Pro enables the scientist to use the tools of Sciworks for more channels of data, to generate more complicated stimulation sequences and waveforms, and to incorporate video acquisition and analysis.
Upgrading to SciWorks Discovery Pro is also cost effective. While you can pay a price difference later to upgrade from the Discovery to the Discovery Pro software package, it is necessary to purchase the required a/d hardware that supports Discovery Pro at full price. Thus, purchasing Discovery Pro upfront means not double paying for acquisition hardware systems.

SciWorks Discovery and Discovery Pro can be configured to run any of the following experiments, and countless others.
The following list contains only a few examples of the variety of experiments SciWorks Discovery can perform and analyze.
Click on the section headings for details and videos regarding how SciWorks can be used in your lab to measure average responses, measure population spike amplitudes, perform Fourier analysis to obtain a power spectrum, interval measurements, detect seizures, and perform many other protocols. Adding VideoBench to either Discovery Pro bundle enables video collection and analysis functionality.
The example experiment is recording two channels of field potential and five channels of continuous EEG in an awake behaving animal using SciWorks Discovery. Discovery generated a biphasic pulse to be delivered at a regular interval. The amplitude of the pulse is maintained for a group of stimulations and then automatically changed to a new value.
For each group of responses an average is calculated. Automatic artifact rejection is applied so that only valid sweeps are accumulated. For each averaged waveform various waveform parameters are calculated (i.e. area, pop spike amplitude and slope) and displayed in the real-time spreadsheet.
Finally, a Fourier analysis is performed on the EEG channels and the power spectrum displayed.
This video demonstrates SciWorks Discovery’s capability to perform simultaneous data acquisition and analysis, as EP parameters Population Spike Amplitude and EP Area are extracted from the elicited evoked potential, logged into a spreadsheet, and plotted on a scatter plot.
The example experiment is configured to record 24 channels of EEG continuously over a 24 hour period of time while looking for a seizure using the Discovery Pro 64 bundle.
A spectral (Fourier) analysis is performed on each of the channels, and the power values calculated for each of the common power bands and were logged to a spreadsheet for additional analysis if needed.
In addition, the power band values of four selected channels are plotted continuously as a contour plot.
This example experiment continuously recorded both EEG and EMG from the animal. Bursts of EMG activity were detected using the Analysis burst detection tool. The burst durations and inter burst intervals were calculated and counted with the values automatically displayed in the spreadsheet.
The detected EMG burst was extracted from the continuous EMG data streams. A Fourier analysis was performed on the extracted waveform and the Fourier transform was added to the running average. The power spectrum was also calculated from the EEG data stream. This was all performed in real-time using SciWorks Discovery Pro, but the same experiment could be performed with SciWorks Discovery.
SciWorks Discovery Pro’s time frequency and burst analysis tools were used to automatically detect and quantify seizure activity. When a potential burst is detected, markers are automatically entered into the output data stream for both the on and off times of the seizure.
In this video, a two seizures are detected and analyzed.
The same experiment can be performed using 8 ch of EEG data with SciWorks Discovery.
With Sciworks Discovery or Discovery Pro, you can sort in real time using either the built-in Autosort algorithm, or customize it to capture the waveforms you want.
Features available during spike sorting include:
This example experiment recorded four channels of multi-unit data continuously along with a single TTL marking channel. The unit activity was detected and the units extracted from the continuous data stream using the built-in AutoSort tool.
Simultaneous with the acquisition of unit activity an auditory stimulus was delivered with white noise in one ear and a tone in the other. A marker in the data stream was added, and peri-event time histograms (PETHs), inter-event interval histograms (IEIHs) and dot rasters were created. Finally, the unit activity firing rate was displayed (by sorted units) in a rate meter display (behind the other windows) for later logging.
SciWorks Discovery Pro 64 enables you to record spikes on up to 32 channels simultaneously with a single breakout box, or 64 channels when paired with two data acquisition boxes (It's the speed of the sampling rate that determines how many channels of spikes you can record). Discovery Pro 16 is fast enough to simultaneously record 16 channels of spikes, while SciWorks Discovery can record spikes on 3 channels with its bundled a/d card.
VideoBench is a suite of tools that adds video capture and tracking capability to your SciWorks Discovery Plus capability.
VideoBench functionality can augment realtime data acquisition as well as be used during postexperiment replay, editing, and analysis.
When the video is simultaneously captured with other types of experimental data (i.e. electrophysiological signals) it is precisely synchronized in time. And don't worry about file size, SciWork’s unique framebyframe compression allows for hours of recording video while still retaining the image quality of any single frame.
In this image, neural responses are coded according to animal behavior, such as active search or supported rearing.
The tracking features of VideoBench provide the functionality needed for "tracking" one or more spots on a framebyframe basis. Spot color and brightness are easily defined using a color sampler. Tracked points can be tracked fullframe or can be limited to one or more regions in either a maze, an open field or multiple cages. Quality of tracking is provided numerically or visually by overlaying points on top of the video. Various orientations, grid, and display options further enhance the tracking capabilities. Tracked points can be saved to file along with other experimental data for further replay, editing and analysis.
VideoBench is not compatible with SciWorks Discovery.
This video shows a Mismatched Negativity Study. Discovery Pro was used to generate audio tones stimuli. Evoked responses to a standard tone were recorded. At random intervals, a deviant tone was introduced to elicit the mismatched ERP. Power was calculated for both the standard and deviant responses after the recorded potentials were smoothed.
Discovery Pro was used to generate audio tones stimuli. Evoked responses to a randomized sequence of frequencies and amplitudes were recorded and quantified. An auditory tuning curve was plotted. Larger amplitude cross-hatches indicate greater neural responses.
An experiment is defined using the built-in tools of SciWorks Discovery or Discovery Pro. These tools are oriented around common experiment tasks, such as data acquisition, stimulus generation and delivery, data display, data analysis, annotation of data, timing, and external device control.

Experimental Control, Execution and Timing
Experimental Design and User Interaction
SciWorks Discovery or Discovery Pro software enables real-time data-analysis while not interrupting data acquisition.
Spike records can be sorted using the AutoSort module, or sorted by a user driven analysis process. Separated spikes can then be catalogued and quantified for use in rasters, histograms, rate calculations, etc.
EEG records can undergo Fourier analysis online.
Population spikes can be measured.
And all of the analyzed data can be stored at the same time as the raw recordings.
Find something interesting in a review of the analyzed data, but need to go back to the original for a re-analysis? No problem. You can call up the entire record, and start anew. Or, you can instantly jump to a particular time stamp, or experiment marker, without having to load in the entire record.
