α2δ-2 mediates coupling of presynaptic calcium entry to vesicle release in hippocampal parvalbumin-expressing interneurons

This study shows that α2δ-2 is essential for synaptic inhibition in hippocampal parvalbumin-expressing interneurons, with its absence leading to increased excitation and seizure-like activity.

Biased synaptic activation of dentate granule cells by exercise reflects inputs from the lateral entorhinal cortex.

The paper shows that exercise preferentially activates dentate granule cells via inputs from the lateral entorhinal cortex, not through dendritic molecular changes.
