Mechanisms of adaptive interlimb coordination to sudden ground loss: a neuromusculoskeletal modeling study Open
Mammals exhibit robust walking across diverse environments, a capability largely attributed to central pattern generators (CPGs) in the spinal cord. Afferent feedback modulates CPG output and plays a critical role in adaptive locomotion, y…
Ionic mechanisms underlying bistability in spinal motoneurons: insights from a computational model Open
Spinal motoneurons are the final output of spinal circuits that engage skeletal muscles to generate motor behaviors. Many motoneurons exhibit bistable behavior, alternating between a quiescent resting state and a self-sustained firing mode…
Reorganization of spinal neural connectivity following recovery after thoracic spinal cord injury: insights from computational modelling Open
Rats exhibit significant recovery of locomotor function following incomplete spinal cord injuries, albeit with altered gait expression and reduced speed and stepping frequency. These changes likely result from and give insight into the reo…

Effects of spinal transection and locomotor speed on muscle synergies of the cat hindlimb Open
It has been suggested that during locomotion, the nervous system controls movement by activating groups of muscles, or muscle synergies. Analysis of muscle synergies can reveal the organization of spinal locomotor networks and how it depen…
State information policy in the context of hybrid threats: Legal and political aspects Open
The study aimed to identify the main ways to optimise the state information policy in order to strengthen the ability to withstand complex hybrid challenges. The study examined modern approaches to the definition of hybrid threats and thei…
Operation of spinal sensorimotor circuits controlling phase durations during tied-belt and split-belt locomotion after a lateral thoracic hemisection Open
Locomotion is controlled by spinal circuits that interact with supraspinal drives and sensory feedback from the limbs. These sensorimotor interactions are disrupted following spinal cord injury. The thoracic lateral hemisection represents …

Role of forelimb morphology in muscle sensorimotor functions during locomotion in the cat Open
Previous studies established strong links between morphological characteristics of mammalian hindlimb muscles and their sensorimotor functions during locomotion. Less is known about the role of forelimb morphology in motor outputs and gene…

Operation regimes of spinal circuits controlling locomotion and the role of supraspinal drives and sensory feedback Open
Locomotion in mammals is directly controlled by the spinal neuronal network, operating under the control of supraspinal signals and somatosensory feedback that interact with each other. However, the functional architecture of the spinal lo…
Changes in intra‐ and interlimb reflexes from forelimb cutaneous afferents after staggered thoracic lateral hemisections during locomotion in cats Open
In quadrupeds, such as cats, cutaneous afferents from the forepaw dorsum signal external perturbations and send inputs to spinal circuits to co‐ordinate the activity in muscles of all four limbs. How these cutaneous reflex pathways from fo…

Properties of rhythmogenic currents in spinal Shox2 interneurons across postnatal development Open
Locomotor behaviors are performed by organisms throughout life, despite developmental changes in cellular properties, neural connectivity, and biomechanics. The basic rhythmic activity in the central nervous system that underlies locomotio…

Forelimb movements contribute to hindlimb cutaneous reflexes during locomotion in cats Open
During quadrupedal locomotion, the coordination of forelimb and hindlimb movements involves central circuits and somatosensory feedback. To demonstrate how forelimb movement affects hindlimb cutaneous reflexes during locomotion, we stimula…

Changes in intra‐ and interlimb reflexes from hindlimb cutaneous afferents after staggered thoracic lateral hemisections during locomotion in cats Open
When the foot dorsum contacts an obstacle during locomotion, cutaneous afferents signal central circuits to coordinate muscle activity in the four limbs. Spinal cord injury disrupts these interactions, impairing balance and interlimb coord…
