Cognitive Neuroscience Lab
The lab has two state of the art EEG ERP systems. One of them is the 64 channel EEG ERP system from Neuroscan and another is the recently acquired 128 channel EEG/ERP system from Electrical Geodesics Inc. The 64 channel EEG/ERP system (Compumedics, Neuroscan) with software for stimulus presentation (STIM2) and analysis (SCAN 4.3) was installed in 2005. The STIM program consists of modules for presenting pre-programmed neuropsychological tasks intended for application in EEG and evoked potential recording paradigms, as well as utility programs for creating one’s own auditory and visual tasks. The Neuroscan AQUIRE program which is the part of the SCAN system is a flexible high speed tool for reliable electrophysiological data acquisition with multiple signal processing features (both online as well as offline). The lab is equipped with measures for saving large quantities of data (extra internal and external hard-disks, DVD writer and colour printer). We have calibrated the system by recording baseline EEG and some ERP data using cognitive tasks on normal subjects. We have worked on projects on meditation, a pre-post study on children with dyslexia undergoing remediation, attention and neuroeconomics using EEG/ ERP measures. We are currently working on studies on sentence processing, bilingualism and cognitive control, and creativity using EEG/ERP.
Neuroinformatics & Intelligent Computing Lab
The lab is well equipped with the latest computers (3 iMACs, and 4 dual Processor servers/workstations) and software like DirectRT, SigmaPlot, MATLAB, SPSS, E-Prime etc. The lab has two servers along with a Network printer as well as a BSNL BROAD BAND High-speed internet connection through LAN. With expanding data collection, there is a need for a powerful server and data storage system which we plan to acquire in the next year.
Visual Cognition Lab
The lab is for the purpose of doing experiments and collecting data to study visual perception, attention, working memory and other related cognitive processes. The visual cognition lab is equipped with two eye trackers which include a head mounted SMI iViewx HED (with HS1250 upgrade & BeGaze software) eye tracker and a remote ASL600 eye tracker for studies on perception, attention, and language. The lab is also equipped with software for stimulus presentation (E-Prime, Presentation, DirectRT and Medialab) along with necessary hardware to perform behavioural experiments. In the next three years, we plan to upgrade the eyetracker systems.
The lab has computers with available software and has a sound proof room suitable for speech recording, stimuli design and computing facility. The current focus of the lab is to study time course of multi modal interactions in auditory as well as visual language processing.
The biofeedback lab is equipped with the Flexicomp Infiniti system with EMG, EEG, temperature, skin conductance, ECG, and respiration sensors.
Virtual Reality Lab
The virtual reality lab has a set of accessory equipment that enables interaction with the user. The lab has a 5DT HMD 800-26-3D, Sensable Pantom Omni Device, 5DT data gloves with wireless kit, Phantom omni development kit, and 4 Ascension flock of birds sensors. The lab also has the Vizard software for developing VR experiments and applications. In the next three years we plan to upgrade the systems and also expand the facilities to perform multisensory perception and learning experiments.
The lab is also equipped with formal neuropsychological test batteries and tests of specific cognitive functions such as Luria’s Neuropsychological test battery for adults, NIMHANS Neuropsychological Battery for adults, AIIMS neuropsychological test battery for adults, NIMHANS neuropsychological battery for children, Cognitive assessment system, NEPSY battery for neuropsychological assessment, Computer assisted Vienna system for cognitive assessment, Wide range achievement test, Phonological assessment battery, Gray oral reading test and specific tests such as Color trails test, Tower of London test, Wisconsin card sorting test, and Stroop test. These tools are used for training students in assessment and interpretation of neuropsychological profiles of patients with cognitive disorders and for research. Software and hardware for data archiving and analysis are available.
A computer based cognitive retraining programme called Brain Function Therapy for training students in cognitive rehabilitation is also available. We also have the Reading Enhancement Programme (PREP) developed by Prof. J.P. Das, University of Alberta, which is a remediation programme for children with dyslexia. The remediation package is based on the PASS Theory of Intelligence (Planning, Attention, and Simultaneous and Successive Processing). It aims at improving the information processing strategies namely, simultaneous and successive processing that underlie reading, while at the same time avoiding the direct teaching of word reading skills. It develops strategies such as rehearsal, categorization, monitoring of performance, prediction, revision of prediction, sounding, and sound blending. We have worked on neuropsychological profiles of children with dyslexia and cognitive impairments in children with ADHD using neuropsychological measures. We have also conducted studies on remediation in dyslexia using PREP program. We are currently working on the dissociation between memory and executive functions as a result of cognitive aging using neuropsychological measures.
