Yann’s first manuscript has been published in eNeuro. In this paper, we describe how the role of glycinergic inhibition to the rhythm of tail beats of developing zebrafish changes around the same time that their swimming maneuvers change. We also show that the emerging contributions of glycinergic inhibition to rhythm of tail beats occurs first in caudal segments of the spinal cord. This work sheds further light on how spinal circuits develop to enable the maturation of motor control that is necessary in growing animals
Great news to start off for the lab. A manuscript describing work from Yann’s PhD thesis has been accepted for publication! More news on this later but thanks to the hard work of co-authors Melissa Paradis, Stéphanie Gaudreau and Ben Lindsay
Alex, Sara, Nic and I authored a review in Frontiers in Cellular Neuroscience describing the latest and most seminal work looking at the role of propriospinal neurons (spinal neurons that communicate between different segments of the spinal cord) in locomotion in the intact and injured spinal cord
Four awards were given to lab members so it’s been a great month. In alphabetical order:
- Anabelle Morissette and Kyra Steiner were awarded NSERC USRA to pursue research projects in the lab this summer.
- Nicolas Lalonde was awarded a Travel Award by the Canadian Association for Neuroscience to attend their annual meeting in Toronto at the end of May
- Stéphanie Gaudreau was awarded a STaR award (value $10,000) to start her Master’s degree in the lab. The award is provided by the Centre for Neuromuscular Disease of the Brain and Mind Research Institute and will allow her to pursue a collaboration with the lab of Dr. Hans Lochmuller to study congenital myasthenia syndromes
It is with great sadness that we say goodbye to postdoctoral fellow Ben Lindsey, who has moved to the University of Manitoba to start his own lab, focusing on neural repair and regeneration using zebrafish. Ben is looking for undergraduate and graduate students to join his lab so please have a look at his website if you are interested.
At the same time, we are very excited to welcome Alex Laliberte who is joining the lab as a postdoctoral fellow. Alex recently completed his PhD in the lab of Michael Fehlings, noted spinal cord injury researcher, at the University of Toronto. Alex will be pursuing projects looking at the role of dI3 interneurons in recovery of locomotor function after spinal cord injury
Congratulations to Yann Roussel successfully defended his PhD thesis, entitled, DEVELOPMENT OF SPINAL CIRCUITS FOR SWIMMING IN ZEBRAFISH (DANIO RERIO) LARVAE. Yann is the first PhD graduate of the lab and he did a tremendous job in his thesis defense. In fact, it was nominated by his thesis committee for a thesis prize. Joe Fetcho from Cornell was the external member of Yann’s thesis committee
Tuan gave a talk as part of a Plenary Symposium on “CNS Regeneration and Plasticity” for the 3rd Joint Symposium of the International and National Neurotrauma Societies in Toronto
Tuan gave a talk at the Sainsbury Wellcome Centre in University College London, a top-notch neuroscience institute. The talk was entitled “Maturation of motor control by the development of spinal circuits” and featured our latest on the development of dI3 interneuron circuitry and on the maturation of spinal circuits for swimming in developing zebrafish. Follow this link to find a Q&A. Many thanks to Emily Reader-Harris, postdoc in Andy Murray’s lab for organizing, and to Andy Murray for hosting.
The lab is participating in the Lap the Gats fundraiser this Sunday to raise money for Parkinson’s Research. Every year when I am done biking 60-80 gruelling kilometres through the hills of Gatineau Park, I tell myself this year will be my last. But the cause keeps bringing me back, much to my out-of-shape body’s chagrin.
Please consider supporting the lab @CrowdRise
Congratulations to David, Eugene, Melissa, and Nicolas for earning their undergraduate degrees. It’s great to see your hard work pay off. Extra congratulations to Melissa for being named Valedictorian!
Postdoctoral fellow Ben Lindsey just published a review in Progress in Neurobiology about neuroepithelial stem cells and radial glial cells and their roles in development and recovery.
POSTDOC POSITION IN PARKINSON’S DISEASE The lab is seeking a postdoctoral fellow to spearhead a project studying the cortico-basal ganglia-thalamic loop in the context of Parkinson’s disease using electrophysiology and optogenetics. Please visit this link for more details.
Tuan gave a talk on Yann and Melissa’s lastest work at a parallel symposium on the development of motor systems at the 12th annual meeting at the Canadian Association for Neurosciences. Ben, Melissa and Yann each gave well attended poster presentations!
Congratulations to post-doctoral fellow Ben Lindsey for receiving a prestigious CIHR fellowship award!
Congratulations to undergraduate honours students David Zheng, Eugene Wang, MaryAnn Wu, Melissa Paradis and Nicolas Lalonde for completing their honours theses. You put in a lot of work and you should be proud of the research you accomplished
We received word in late December that a 2-year team grant involving Drs. Brian Chow (UBC), Michael Hildebrand (Carleton), Vivial Mushahwar (University of Alberta), and Eve Tsai (OHRI) was being funded by the Ontario Neurotrauma fund. This funding will allow our team to further pursue the use of spinal cord cell cultures derived from pig and from live human spinal cord tissue to devise improved treatments of spinal cord injury. We thank the Ontario Neurotrauma Fund for this tremendous opportunity. Please see this link for further information.
We co-organized with Dr. Eve Tsai from the OHRI, the inaugural Ottawa Spinal Cord and Brain Regeneration meeting held at the uOttawa Skills and Simulations Centre at the Civic Hospital. About 60 researchers and trainees attended the day event, which consisted of many stimulating talks describing the latest and most innovative research done in Ottawa looking into treating and assessing spinal cord injury and neurotrauma.
This was followed in the evening by a public event as part of the Brain Health Awareness Week organized by the uOttawa Brain and Mind Research Institute. Over 170 attendees heard from a panel consisting of Tuan, Dr. Mike Hildebrand, Dr. Andrew Pelling, Dr. Eve Tsai and Dr. Jing Wang about exciting research into treatment of spinal cord injury and neurotrauma.
Thanks to all of those who assisted and attended the events. Also, thanks to the generous support of the uOttawa Brain and Mind Research Institute, the Ontario Neurotrauma Fund, the OHRI, and the Bhargava family. It was a milestone day for spinal cord and brain regeneration research in Ottawa.
Tuan received an Early Researcher Award from the Ministry of Research and Innovation of Ontario. This $150,000 award will allow the lab to fund PhD students and to hire a postdoctoral fellow to study questions related to the recovery of movement following spinal cord injury.
It is thus with great pleasure that we welcome Ben Lindsey as a postdoctoral fellow to the lab. Ben completed his PhD in the lab of Vince Tropepe at the University of Toronto and followed this up with a short Postdoctoral fellow at Monash University under Jan Kaslin. We were able to convince him to move back to Ontario and to do a postdoctoral fellowship in the lab where his work on adult stem cells in zebrafish will be applied to spinal cord injury work in mammalian and fish models.
Yann received an award for best poster by a Senior PhD student at Brain Health Research Day for his poster looking at the involvement of glycine in the operation of spinal locomotor networks at different developmental stages of the zebrafish. Congratulations for a well-deserved award!
