Epigenetic reprogramming of the distinct repressive marks H3K27me3 or H3K9me2 guides the transition between the haploid and diploid life forms that encompass the life cycle of land plants.

Complex motor behaviors can be assembled from simpler repeating elements controlled by pattern-generation circuits operating at different time scales.

The ancestral mechanism to activate diploid gene expression via homeodomain transcription factors was retained in liverworts, an early diverging land plant lineage, and subsequently co-opted during evolution of the diploid sporophyte body.

Hippocampal sharp-wave sequences, which are considered the key phenomenon underlying consolidation of episodic memory, are preserved even after an animal’s memory is impaired.

Organization of commissural and long propriospinal neuronal pathways defines gait expression in quadrupeds.

Two classes of premotor inhibitory neurons have specific roles in controlling flexor-extensor behaviors in mice, which is the underlying neural mechanism for limb driven movements in terrestrial vertebrates.

Silencing long-descending propriospinal neurons that connect C6 to L2 disrupts right-left alternation of both the forelimbs and hindlimbs in the intact animal, but leads to improved stepping after a mild-moderate thoracic contusion spinal cord injury.

Computational models of spinal locomotor circuits in developing zebrafish reveal how new movements can emerge during development through the integration of new spinal neurons and new connections.

The forward locomotor circuit of the roundworm Caenorhabditis elegans consists of multiple rhythm-generating units coupled to one another in a bidirectional manner.

Computational modeling reveals the mechanisms by which a diverse group of neurons in the brainstem generates rhythmic breathing in mammals.
