Transcriptional and cellular maturation of the chick spinal cord in the context of distinct neuromuscular circuits

The paper studies the transcriptional and cellular maturation of the chick spinal cord at single-cell resolution, revealing similar cell type repertoires for wings and legs and limited transcriptional changes with spatially restricted plasticity in motor neurons.

Temporal control of axonal floor plate crossing through a combination of incoherent feedforward and feedback loops of gene regulatory network regulating Robo3 expression

The paper shows that Robo3 expression in spinal commissural neurons is controlled by gene regulatory networks involving incoherent feedforward and feedback loops, which determine midline crossing.

Spinal dI2 interneurons regulate the stability of bipedal stepping

This study identifies dI2 spinal interneurons in chicks that regulate bipedal stepping stability by integrating peripheral and intraspinal feedback.

Natural loss of function of ephrin-B3 shapes spinal flight circuitry in birds

This study shows that the loss of ephrin-B3 function in birds shapes spinal flight circuitry by enabling synchronous wing flapping through altered midline signaling.
