This paper introduces squeezed light field microscopy (SLIM), a method for high-speed 3D volumetric imaging, and demonstrates its application in tracking blood cell motion and neural activity in vivo.

The paper introduces Neuropixels 1.0-NHP, a high-density electrode array for large-scale neural recording in nonhuman primates, enabling recording from over 3000 single neurons.

This paper develops a hydrogel-based biosensor for continuous nicotine measurement in human biofluids, achieving detection at sub-100 nM levels with high stability and sensitivity.

The paper investigates how a motor neuron dynamically switches roles across behaviors without changing its anatomical connections by analyzing circuit anatomy and activity patterns.

This study shows that dorsal raphe dopamine neurons encode motivational salience, responding to reward and punishment cues and modulated by internal and external states.

The paper shows that persistent neural activity in VMHdmSF1 neurons mediates anxiety-like behavior after exposure to threatening stimuli, without relying on hardwired circuits.

The paper identifies two photoreceptor classes in Hirudo verbana and shows their role in complex visual integration through electrophysiology and transcriptomics.

The paper quantifies how the S cell in the medicinal leech responds to visual and mechanical water wave cues, finding frequency-dependent sensitivity and no directional selectivity.

The paper develops a double-sided microscope for whole-ganglion voltage imaging in medicinal leeches and uses it to analyze neuronal dynamics in sensory processing and behavior generation.
