Movement is governed by rotational population dynamics in spinal motor networks

The paper shows that spinal motor networks generate movement through rotational dynamics in neural activity rather than alternating activity, with rotation radius correlating to muscle force.

Brain temperature affects quantitative features of hippocampal sharp wave ripples

This study shows that brain temperature in the hippocampal CA1 region influences ripple frequency but not other SPW-R parameters.

Metal microdrive and head cap system for silicon probe recovery in freely moving rodent

The paper introduces a recoverable and reusable microdrive and head cap system for silicon probe recovery in freely moving rodents, reducing cost and experimental complexity.

Cooling of medial septum reveals theta phase lag coordination of hippocampal cell assemblies

The paper investigates how cooling the medial septum affects theta oscillations and spatial navigation, finding that it reduces theta frequency and disrupts phase coordination of cell assemblies.

CellExplorer: a graphical user interface and standardized pipeline for visualizing and characterizing single neuron features

CellExplorer provides a framework for visualizing and characterizing single neuron features through standardized processing and a graphical interface.

Decoupling of timescales reveals sparse convergent CPG network in the adult spinal cord

The paper uses synaptic correlation measurements to infer the wiring architecture of a spinal CPG network, finding sparse convergent connectivity or active decorrelation.

Lognormal firing rate distribution reveals prominent fluctuation-driven regime in spinal motor networks

The paper identifies a fluctuation-driven regime in spinal motor networks, showing half of neurons spend significant time in this regime across multiple motor behaviors.
