This research investigates how specific types of inhibitory interneurons—specifically parvalbumin (PV) and somatostatin (SST) cells—regulate neural activity within the dentate gyrus of the hippocampus in active mice. By utilizing machine learning to classify neurons based on their physiological features, the authors identified unique roles for these cells in managing signals from the entorhinal cortex. The study highlights that SST interneurons are critical for gating excitation during specific brain events called dentate spikes, while PV interneurons provide essential feedback inhibition…
