The aural cavity magnetic susceptibility artifact leads to significant echo planar NEFF D65BMP5N0B N70 Built In 60cm 5 Speeds A Chimney Cooker Hood Stainless imaging (EPI) signal dropout in rat deep brain that limits acquisition of functional connectivity fcMRI data.In this study, we provide a method that recovers much of the EPI signal in deep brain.Needle puncture introduction of a liquid-phase fluorocarbon into the middle ear allows acquisition of rat fcMRI data without signal dropout.We demonstrate that with seeds chosen from previously unavailable areas, including the amygdala and the insular cortex, we are able to Travel Cups acquire large scale networks, including the limbic system.

This tool allows EPI-based neuroscience and pharmaceutical research in rat brain using fcMRI that was previously not feasible.
