Neuronal populations across the cortex underlie discrete, categorical, and subjective representations of visual durations
Duration perception involves multiple brain regions, but how unimodal tuning across this network supports subjective timing remains unclear. This study shows that parietal, premotor, and caudal SMA en...

A new MRI protocol can scan the human brain and its venous network in under 7 minutes at 0.35 mm iso. resolution, marking it as a potential tool for diagnosing cerebrovascular diseases and monitoring neurodegeneration.
