Introduction
The Blackrock NeuroMotive™ System is a video recording/playback system with optional tracking capabilities. It
allows for synchronized recording and tracking of animal subjects.
System Description
The NeuroMotive™ System is designed to record and process video frames from a single camera. The system
works standalone and in conjunction with the Cerebus™ or the CerePlex™ Direct (NeuroMotive™ must run on its
own PC with the Central Software running on a separate PC). Each frame is time-stamped and can be synchronized
with the neural, analog and digital experimental data recorded with the Cerebus™ or CerePlex™ Direct.
NeuroMotive™ playback relies on nPlayServer which is an offline experiment playback tool that simulates the data
acquisition system on recorded neural data; replaying the recorded data and allowing further signal processing of the
data. The combination of NeuroMotive™ (under Cerebus™) and nPlayServer accomplish synchronized video-
neural playback. This playback can include tracking data even if the feature has not been purchased.
The system is capable of sampling video at a rate of up to 100 fps (requires hardware synchronization). The
maximum frame rate depends on the type of camera used.
Minimum System Requirements
Microsoft Windows 7 Professional Edition 64-bit
Intel Quad Core or Core i5 CPU with at least 4 processor threads (i.e., ‘cores’) running at 3.2 GHz or faster
8 GB of RAM
1 TB 6Gbit/s SATA III HDD
Powerful discrete video/graphics card (e.g., NVIDIA GeForce GTX 550 Ti or Greater series)
1 Gigabit Ethernet adapter
1 Gigabit Ethernet switch if connecting to an NSP
1 USB 2.0 port for the camera

NeuroMotive™ Camera Options
The NeuroMotive™ system has multiple options for the camera type. The camera-NeuroMotive™ PC interface
depends on the camera type and synchronization method. If using software synchronization or if not using
NeuroMotive™ in conjunction with a neural data acquisition system then simply connect the camera to the
NeuroMotive™ PC. If using hardware synchronization then use the following guidelines:
1. FireFly MV
The Firefly MV camera has three lens rings that can be twisted see Figure 4. The arrows denote individual
lens rings. Starting with the leftmost ring and moving right the first ring is for zooming in on the scene, the
second ring is the focus for reducing blur and the third ring is the open/close iris for receiving more or less
light.
Figure 4 –The Firefly MV camera.
Connect the camera via USB to the NeuroMotive™ PC and connect the camera to the NSP or CerePlex™
Direct using the supplied hardware synchronization cable (Refer to the CerePlex™ Direct User Manual for
configuring the Direct to use hardware synchronization with NeuroMotive™). For the NSP attach the cable
to a Digital Output Port and for the CerePlex™ Direct attach the cable to the NeuroMotive™ camera port
on the rear of the device. Here’s an example of the system connected to an NSP.

The software on the NeuroMotive™ Motion Capture PC is pre-configured. In the case that the system needs to be
re-configured follow the steps below:
1. Click on Start and search for
“View Network Connections”.
2. Right click on the correct
Ethernet Adapter (usually,
Local Area Connection or
NSP) and click on Properties.
3. Uncheck all services except for Internet Protocol
(TCP/IP) or Internet Protocol Version 4 (TCP/IPv4).
4. Click on Internet Protocol (TCP/IP) and click on
Properties
5. For IP Address enter 192.168.137.2, for Subnet Mask
enter 255.255.255.0 and leave the rest blank. Make sure the IP
address entered here does not conflict with any other PCs on the
same instrument network. For example, if the Cerebus™ Host PC
is using 192.168.137.2 then choose another IP address within the
range. IP addresses up to 192.168.137.16 can be used.
6. Click on OK to save changes.
Note: This guide assumes that the Cerebus™ Host PC has IP
address 192.168.137.1.
Note: Up to 16 PCs can be connected to the same NSP using a
1-Gbps network switch. For other PCs connected using a
network switch, IP addresses should increment, such as
192.168.137.2, 192.168.137.3, etc.
Note: For reference, the NSP’s IP address is 192.168.137.128.
Note on Playback: If playing back a video file with
NeuroMotive™ in conjunction with a neural data file in
nPlayServer and Cerebus™ Central software ensure that
Central is open prior to NeuroMotive™ in order for the
software to properly synchronize the data files for playback.

NeuroMotive™ Software
Installation
The software comes preinstalled on the NeuroMotive™ Motion Capture PC. If not please run the NeuroMotive™
Windows Installer.msi and other included installers from the supplied CD and follow the instructions.
NeuroMotive™ Main Window
To run the NeuroMotive™ application click on the NeuroMotive™ icon on the desktop, alternatively click on the
Start Menu and select the program under All Programs\Blackrock Microsystems. The main window consists of the
video display, the toolbar, 5 dock bars and a status bar at the bottom. The five dock bars are for Playback Control,
Camera Control, Image-capture status, Regions of Interest (ROI), and Tracking Marker Definition. The ROI and
Marker dock bars come with the optional tracking feature. The NeuroMotive™ application operates in two modes,
Camera and Playback. If a camera is connected and active when NeuroMotive™ is opened, the Camera mode is
automatically chosen and the image from the camera is shown on the Video Display. By setting the Video Source
under Video Display in the advanced options menu (Tools->Options) to the camera connected to the NeuroMotive™
PC the mode is also switched to Camera mode. When a file is opened or the NeuroMotive™ software is opened
while nPlayServer is running, the mode is switched to the Playback mode. Playback mode is also accessible by
setting the Video Source to File in the advanced options menu.

LB-0336 Rev. 1.00 Page 14
NeuroMotive™ File Types
NeuroMotive™ produces the different file types listed below:
Configuration Files
o.xml - NeuroMotive™ creates and updates an options.xml file in the Experiment Directory that
holds all the most current configuration settings for NeuroMotive™. Upon startup NeuroMotive™
searches for this file; if it is found NeuroMotive™ configures itself to the settings listed in the file,
otherwise it creates a new options.xml, sets itself to default settings and stores those settings in
the file. It is important to note that this file is constantly updating as settings are changed.
o.ncf - This file is always created when recording a video file and has the same name as that file. It
can be considered a ‘snapshot’ of the options.xml file because it saves the configuration of
NeuroMotive™ as it is at the time it is created, for instance when a recording is started. This file
can then be loaded using File->Open Experiment to reset NeuroMotive™ to how it was at the
time of the recording.
Video Files
Based on the video recording options selected, one of the following file types will be used:
o.mpg - These contain MPEG2 video files, most video players can play these. See Advanced
Options for more details.
o.mp4 - These contain H.264 video files, most current video players can play these. See Advanced
Options for more details.

NeuroMotive™User’s Manual
