Hippocampo-septal inhibitory feedback controls the medial septal circuit as a function of brain state, pyramidal cell activity and movement speed.

This study shows that hippocampo-septal feedback inhibits the medial septal circuit based on hippocampal activity and movement speed, without being essential for theta rhythm generation.

Absolute number of three populations of interneurons and all GABAergic synapses in the human hippocampus

The paper estimates the absolute numbers of three GABAergic interneuron populations and total GABAergic synapses in the human hippocampus using stereological and electron microscopy techniques.

Parvalbumin-expressing basal forebrain neurons mediate learning from negative experience

This study identifies a role for parvalbumin-expressing basal forebrain neurons in associative learning from negative experiences through calcium imaging and optogenetic experiments.

Synaptic and dendritic architecture of different types of hippocampal somatostatin interneurons

The paper quantitatively compares anatomical and physiological properties of OLM and HS hippocampal interneurons using 3D reconstructions, electrophysiology, and modeling.

Synaptic co-transmission of acetylcholine and GABA regulates hippocampal states

The paper reveals that hippocampal cholinergic terminals form synapses and co-transmit GABA and acetylcholine via distinct vesicles, influencing hippocampal activity and potential therapeutic strategies.
