Slow Intrinsic Oscillations in the Ventrolateral Preoptic nucleus

The paper identifies rhythmic bursting in a subset of VLPO neurons, showing it is intrinsic and may contribute to sleep regulation.

Lactate is a major energy substrate for cortical neurons and enhances their firing activity.

The paper shows lactate enhances cortical neuron spiking activity through KATP channels and is preferentially used as an energy substrate over glucose.

Dissociation of fear initiation and maintenance by breathing-driven prefrontal oscillations

This study shows that breathing-driven prefrontal oscillations sustain fear maintenance in mice without affecting its initiation.

General Regulatory Factors control the fidelity of transcription by restricting non-coding and ectopic initiation

This study shows that General Regulatory Factors like Rap1 suppress ectopic transcription initiation and maintain nucleosome positioning, ensuring transcription fidelity in yeast.

Harnessing sleep/wake state tracking by olfactory bulb oscillations to perform fully brain-based sleep scoring in mice

This paper develops a brain-based sleep scoring method using olfactory bulb and hippocampal oscillations in mice, achieving high accuracy comparable to EMG and video tracking.
