EYE-TRACKING: The eye-tracking facility includes a Tobii TX 300 eye-tracker and comes with the Tobii Studio™ eye-tracking software. This is a state-of-the-art eye-tracking facility that can collect data pertaining to saccades, correction saccades, fixation duration, pupil size and blinks. The facility also includes the Tobii toolbox, which supports data collection using MATLAB, thus minimizing the use of Tobii studio for experimental design. Support is also available for E-Prime through extensions from Tobii.
PSYCHOPHYSIOLOGY LAB: The wireless physiology-based data acquisition system (Biopac Systems Inc) facilitates real-time data acquisition of physiological signals such as ECG, EMG, EDA and provides excellent signal quality with digital transmission with high resolution of 16 bit and at high speed up to 400 kHz aggregate. The system is compatible with the virtual reality-based programming platform Vizard from WorldViz Inc. The Centre has also acquired a 3D virtual reality display (Oculus Rift).
HIGH-DENSITY ELECTROENCEPHALOGRAPHY (EEG): A high-density EEG system is available with 128 channel Geodesic sensor nets that are saline-based for quick application to participants. The system is integrated with E-Prime and MATLAB for stimulus presentation. NetStation software is used for recording and processing of the data. The data can also be exported to open-source and popular processing toolboxes such as EEGLab in MATLAB. The software capabilities include AmpServer Pro licence for real-time sampling of raw data up to 8KHz for Brain-Computer Interfacing Applications.
Emotiv EPOC 16 Channel wireless EEG system – Research Edition
Emotiv EPOC / EPOC+ features 14 EEG channels plus 2 references offering optimal positioning for accurate spatial resolution. Channel names based on the international 10-20 ,electrode location system are: AF3, F7, F3, FC5, T7, P7, O1, O2, P8, T8, FC6, F4, F8, AF4, with CMS/DRL references in the P3/P4 locations. Emotiv EPOC / EPOC+ uses sequential sampling method, single ADC, at a rate of 128 SPS or 256 SPS* (2048 Hz internal). Emotiv EPOC / EPOC+ operates at a resolution of 14 bits or 16* bit per channel with frequency response between 0.16 – 43 Hz.
DIGITISING TABLET: GTCO CalComp digitising tablet records the end point movement of the hand. It has a functional area of 36X24 cm and records the movement of a stylus on the surface of the tablet. It can record the movement of the stylus at the rate of 60 Hz.
BRAIN STIMULATION: The facilities include a transcranial Magnetic Stimulation (TMS) system for non-invasive stimulation of the brain. The TMS system is coupled with a neuronavigation system which can use the MRI scan of a participant for precise targeting of single or repetitive magnetic pulses to localise brain regions of stimulation. The transcranial Direct Current Stimulation (tDCS) is used for non-invasive stimulation of the brain by using a small direct current across the scalp to modulate brain function. Even extremely low-level currents may simultaneously increase the brain’s activity near the anode and decrease the activity near the cathode.
ROBOTIC SYSTEM: The bilateral Kinarm End-Point robot is a stiff, graspable robot that ensures simultaneous control of both robots for comparison of inter-arm performance and the study of bimanual coordination.
