The Drosophila connectome reveals Axo-Axonic Synapses on Descending Neurons

The paper maps axo-axonic synapses onto descending neurons in the Drosophila ventral nerve cord and identifies their functional roles in motor control.

Interleaved single and bursting spiking resonance in neurons

This paper investigates how intrinsic conductances and oscillatory inputs influence the transition between single spiking and bursting in hippocampal neurons, identifying frequency-specific resonance mechanisms.

Dendritic synaptic integration modes under in vivo-like states

The paper investigates how inactivating currents modulate dendritic synaptic integration modes under in vivo-like conditions, finding that potassium currents favor coincidence detection while calcium and sodium currents promote integration.

Prevalent co-release of glutamate and GABA throughout the mouse brain

The paper demonstrates that glutamate and GABA are co-released by neurons in multiple brain regions, as evidenced by biphasic miniature postsynaptic currents observed in striatal neurons and other areas.

Highly sensitive genetically-encoded sensors for population and subcellular imaging of cAMP in vivo

The paper develops improved genetically-encoded cAMP sensors, cAMPFIREs, for high-sensitivity in vivo imaging of cAMP dynamics in neurons and Drosophila.

Contribution of individual excitatory synapses on dendritic spines to electrical signaling

The paper investigates electrical signaling in dendritic spines using voltage imaging and finds no significant attenuation of uEPSPs across the spine neck, suggesting spines are not electrically isolated from parent dendrites.

Mechanisms of high-intensity sound exposure on inhibiting hippocampal long-term potentiation: role of brain-derived neurotrophic factor

This study investigates how high-intensity sound exposure inhibits hippocampal long-term potentiation (LTP) by reducing brain-derived neurotrophic factor (BDNF) levels and shows that BDNF or TrkB agonists can reverse this effect.

Increased hippocampal GABAergic inhibition after long-term high-intensity sound exposure

This study shows that prolonged exposure to high-intensity sound increases GABAergic inhibition in hippocampal CA1 neurons, potentially reducing long-term potentiation.

Reimplementation of the Potjans-Diesmann cortical microcircuit model: from NEST to Brian

This paper replicates the Potjans-Diesmann cortical microcircuit model in Brian 2, achieving similar activity dynamics as the original NEST implementation.
