BESA Research 7.1 - Complete
BESA Research stands out as an unparalleled and intuitive software equipped with efficient tools and scripts designed to preprocess raw or averaged EEG and MEG data for source analysis and connectivity examination. All crucial components of source analysis and imaging are conveniently consolidated into a single window, offering immediate access to a diverse array of tools. This seamless accessibility extends to modules such as source coherence/time-frequency and other analysis interfaces. BESA Research streamlines hypothesis testing, incorporating various source analysis algorithms encompassing cortical and volume imaging techniques, seamlessly integrating with MRI and fMRI. It features age-appropriate template head models (FEM) and facilitates the importation of individual head models (BEM and FEM) generated by BESA MRI, ensuring comprehensive functionality and ease of use. Elevate your research and clinical practice with precision, efficiency, and unparalleled depth of understanding.
