[Tablet-based EloQ software for presenting tasks during brain function mapping].

Functional mapping of cortex and white matter tracts is important in surgery for epilepsy and supratentorial tumors. One of the limitations for speech mapping is difficult standardization, selection and presentation of stimuli during cortical stimulation.

OBJECTIVE To develop a user-friendly tablet application for creation of customized stimulus packages specific to speech cortex and white matter tracts for their presentation during mapping.

RESULTS The EloQ application contains predefined task packages for mapping of non-motor cortical functions of dominant hemisphere. It is supplemented with system for their automatic selection depending on intended mapping area. EloQ offers various image display and audio settings allowing it to be used not only in the operating theater but also in long-term invasive electroencephalography (EEG) monitoring ward. The application is freely available, and physician survey using a 5-point Likert scale showed overall satisfaction with EloQ.

CONCLUSION Free EloQ tablet application simplifies and standardizes non-motor cortical mapping expanding the possibilities of neurosurgical treatment of gliomas and drug-resistant epilepsy.
