A psycho-verbal stimulation interface for the cognitive evoked potentials acquisition

The psycho-verbal stimulation interface, created by us, represents an IT extension of an EEG / EMG device dedicated for the human brain Evoked Potentials acquisitions (EPs).

The psycho-verbal stimulation interface was created as a .NET application and was written in the C# language with respect to the OOP paradigm. It uses the TL logic to command the EPs acquisition module. The signal is send on the parallel port (LPT1) to the EPs device by a dedicated hardware interface. The software module was designed as a multi-threading application in order to perform more than one operation once.

The stimulus sample can be customized as text, image or both and each stimulus sequence follows also a fully configurable time schema. The application can measure the patient's reaction time to each stimulus sample, which are finally centralized on a list control. The system can save both the test sequences and the EEG diagrams in digital formats; the resulted files can be stored and delivered online using the Telemes web application.

The Telmes project implemented a secured & scalable tele-medical centers network dedicated to the telemonitoring & tele-consulting services, and the psycho-verbal stimulation interface is one of the instruments devoted to these goals. The psycho-verbal stimulation interface can be used as a medical research tool for study the cognitive processes of reading, memory or learning using the endogenous visual event related potentials, as good as a instrument of training the recovery of sensitive language, which can be delivered at home by the neuro-linguist specialist as daily lists programs. The visual evoked potentials and the reaction times collected from the patients can facilitate a prognostic diagnosis of recovery the language.
