Spatiotemporal response of rat visual cortex during moving stimuli using Functional Ultrasound (fUS) imaging

The spatiotemporal study of the visual system of the rodent is a challenging area that conventional functional imaging modalities, despite fundamental achievements, still struggle to study nowadays. In the other hand Functional Ultrasound (fUS) offers an unprecedented combination of spatiotemporal resolution. By coupling fUS with an adapted visual stimulation device, we mapped the vision-evoked activity in the rodent brain. We then optimized the visual-stimulus toward the spatiotemporal study of the rodent visual pathway using fUS.
