This study shows that Cx36 gap junctions in the mouse olfactory bulb are important for fine odor discrimination and late excitation of mitral cells.

This study investigates olfactory deficits in Fmr1 KO mice, finding enhanced excitability in mitral cells and impaired fine odor discrimination in complex odor tasks.

The paper tests a high-pass filtering model in olfactory bulb glomeruli by comparing PG cells and eTCs, finding that PG cells are not more responsive to weak stimuli than eTCs.

The paper investigates synaptic connections within olfactory bulb glomeruli and finds strong inhibition from PG cells to eTCs but limited direct excitation between eTCs and PG cells.

The paper demonstrates that extrasynaptic glutamatergic signaling in olfactory bulb glomeruli creates a thresholding effect by balancing excitation and inhibition, allowing only strong stimuli to produce an output.
