Mari S, Lecomte C, Merlet A, Audet J, Yassine S, Arab R, et al.
J Physiol . 2024 Sep; 602(22):6225-6258. PMID: 39340178
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....

Harnie J, Arab R, Mari S, Yassine S, Eddaoui O, Jehannin P, et al.
J Neurophysiol . 2024 May; 131(6):997-1013. PMID: 38691528
During quadrupedal locomotion, interactions between spinal and supraspinal circuits and somatosensory feedback coordinate forelimb and hindlimb movements. How this is achieved is not clear. To determine whether forelimb movements modulate...

Mari S, Lecomte C, Merlet A, Audet J, Yassine S, Eddaoui O, et al.
J Physiol . 2024 Apr; 602(9):1987-2017. PMID: 38593215
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...

Audet J, Lecomte C, Harnie J, Yassine S, Arab R, Soucy F, et al.
J Physiol . 2023 Nov; 602(1):183-204. PMID: 38016922
Mammals walk in different directions, such as forward and backward. In human infants/adults and decerebrate cats, one leg can walk forward and the other backward simultaneously on a split-belt treadmill,...

Lecomte C, Mari S, Audet J, Yassine S, Merlet A, Morency C, et al.
J Neurosci . 2023 Jul; 43(31):5623-5641. PMID: 37474307
Following incomplete spinal cord injury in animals, including humans, substantial locomotor recovery can occur. However, functional aspects of locomotion, such as negotiating obstacles, remains challenging. We collected kinematic and electromyography...

Mari S, Lecomte C, Merlet A, Audet J, Harnie J, Rybak I, et al.
Front Syst Neurosci . 2023 Jun; 17:1199079. PMID: 37360774
Introduction: During locomotion, cutaneous reflexes play an essential role in rapidly responding to an external perturbation, for example, to prevent a fall when the foot contacts an obstacle. In cats...

Audet J, Yassine S, Lecomte C, Mari S, Soucy F, Morency C, et al.
eNeuro . 2023 Jun; 10(6). PMID: 37328297
Spinal sensorimotor circuits interact with supraspinal and peripheral inputs to generate quadrupedal locomotion. Ascending and descending spinal pathways ensure coordination between the forelimbs and hindlimbs. Spinal cord injury (SCI) disrupts...

Audet J, Yassine S, Lecomte C, Mari S, Felix S, Caroline M, et al.
bioRxiv . 2023 Mar; PMID: 36993268
Significance Statement: Coordinating the limbs during locomotion depends on pathways in the spinal cord. We used a spinal cord injury model that disrupts communication between the brain and spinal cord...
