 Electroencephalography and event-related potentials
A variety of specialized lines of research require highly flexible
EEG data
acquisition and signal processing tools and unique
accessory items. EEG provides an objective measure of brain
activity that has excellent temporal resolution and better spatial
resolution than most people imagined possible just a few years ago.
We offer a variety of data acquisition, signal processing, stimulus
delivery, consumable products and other accessories to
meet a wide variety of research needs. |
 Brain-computer and brain-machine interface
A
variety of interesting lines of research require on-line
processing of acquired signals in order to control a computer or
other machine. Some simple examples of these applications
include the use of EEG signals to write text using a 'speller'
application or to control a mechanical robot or prosthesis.
This type of application is often referred to as a
brain-computer interface (BCI), since often the goal is to
create an interface between the subject's brain activity and a
device. Since BCI is still a very fertile area of
research, scientists in the field require a development toolkit
rather than a set of canned algorithms to advance the science.
We offer a range of options for on-line signal processing and
BCI research.

 Electrocardiography and body-surface
potential mapping
We
offer data acquisition systems and signal processing tools with
the most advanced features for research involving cardiac
potentials. Dense spatial sampling of cardiac potentials
at the skin surface has become not only possible but practical
and accessible with the advent of inexpensive, turn-key data
acquisition systems. Not only that, but we have a simple
solution for accurate measurement of 3D electrode positions and
landmarks for coregistration of surface measured cardiac
potential data with MRI, CT fMRI or PET images. Similarly,
signal processing algorithms incorporating surface measured
potentials, electrode positions and anatomical/functional images
are no longer the domain of the select few with the know-how to
write their own software code. Check the list of powerful
tools we provide. |
 Data acquisition and signal processing
for psychophysiology
Psychophysiologists
use multimodal physiological measurements to characterize
physiological correlates of experimental manipulations.
EEG is a commonly measured parameter; however,
psychophysiological studies often include measures relating not
only to central but peripheral nervous system activity. In
addition to EEG, psychophysiologists often use ECG, EMG, EOG,
respiration rate, temperature, pulse/heart rate, and a number of
other parameters. We offer a number of data acquisition
systems and signal analysis solutions useful in
psychophysiological research. |
 Multi-cage / multi-channel EEG, EMG and
activity monitor
ActiveRat
is an elegant solution for collecting multi-channel EEG, EMG and activity
(infrared detector) data
from multiple freely-moving small animals. The system architecture
incorporates amplification and 24-bit analog-to-digital conversion in a
single, compact unit located inside or immediately adjacent to the animal
housing. Up to 32 A/D boxes are synchronized but remain galvanically
isolated from each other by means of a fiber-optic data daisy chain.
Systems with more than 32 A/D boxes connected to a single host PC are also
possible on a custom basis, with a proportional reduction in channels per
cage and/or sample rate.
