CSHC - Center for the Study of Human Cognition

CogLab is a computer based laboratory facility for the collection of behavioural data. It consists of seven laboratory cells, each with a computer based setup for a wide range og cogntitive experiments, running E-Prime and PsycToolbox aplications. One cell is set up with a tachistoscope with a precision of 1 ms exposure based on LCD shutter technology. Allowing for well controlled studies of visual stimuli like subliminal priming. In addition this room is shielded against radiowaves to allow for a controlled psychophysiology environment with equipment to record EMG, ESR and a 32 channel EEG . One cell is set up with a EyeView eyetracker to support studies involving eye gaze and movements.

Event-related potentials (ERPs) are changes in electrical currents in response to stimuli and cognitive tasks. By ERP it is possible to measure brain activity at a very high temporal scale, e.g. by doing registrations of brain activity thousand times a second. In contrast to measures of bloodstream, like fMRI and PET, ERPs are assumed to be direct reflections of neural activity, and is a very powerful tool in the study of human cognition. The three parameters of ERP are the strength of the response (amplitude), the speed of the response (latency), and the localization of the response (the scalp topography).

We have a laboratory dedicated to analysis of neuroimaging data. At the moment, the lab consists of 10 workstations and 30 processing units, most of which runs Linux (Fedora Core 4). With the exception of use of NeuroScan software for some ERP-preprocessing and a minor part of the workstations running windows, the programs used are freely available and mostly open-source.
