Boissonneault W, Lemieux M, Bretzner F, Galstian T
Biomed Opt Express
. 2025 Jan;
16(1):68-83.
PMID: 39816139
A miniature electrically tuneable liquid crystal component is used to steer light from -1° to +1° and then to inject into a simple tapered fiber. This allows the generation of...

Biomed Opt Express
. 2024 Mar;
15(3):1750-1760.
PMID: 38495724
We describe a mini-endoscope design that uses a new type of electrically tunable liquid crystal lens array enabling the dynamic increase of spatial resolution by adjusting the working distance in...

Lemieux M, Karimi N, Bretzner F
Nat Commun
. 2024 Feb;
15(1):1542.
PMID: 38378819
Spinal cord injury disrupts the descending command from the brain and causes a range of motor deficits. Here, we use optogenetic tools to investigate the functional plasticity of the glutamatergic...

Roussel M, Lafrance-Zoubga D, Josset N, Lemieux M, Bretzner F
Cell Rep Med
. 2023 Feb;
4(2):100946.
PMID: 36812893
Spinal cord injury (SCI) results in a disruption of information between the brain and the spinal circuit. Electrical stimulation of the mesencephalic locomotor region (MLR) can promote locomotor recovery in...

Thiry L, Lemaire C, Rastqar A, Lemieux M, Peng J, Ferent J, et al.
eNeuro
. 2022 Feb;
9(2).
PMID: 35115383
Axon guidance receptors such as deleted in colorectal cancer (DCC) contribute to the normal formation of neural circuits, and their mutations can be associated with neural defects. In humans, heterozygous...

Lemieux M, Thiry L, Laflamme O, Bretzner F
Int J Mol Sci
. 2021 Aug;
22(16).
PMID: 34445216
Locomotion results in an alternance of flexor and extensor muscles between left and right limbs generated by motoneurons that are controlled by the spinal interneuronal circuit. This spinal locomotor circuit...

Marques D, Gargaglioni L, Joseph V, Bretzner F, Bicego K, Fournier S, et al.
Brain Res
. 2021 Jan;
1756:147276.
PMID: 33422531
The neural network that regulates breathing shows a significant sexual dimorphism. Ovarian hormones contribute to this distinction as, in rats, ovariectomy reduces the ventilatory response to CO. Microglia are neuroimmune...

Tenorio-Lopes L, Fournier S, Henry M, Bretzner F, Kinkead R
Transl Psychiatry
. 2020 Nov;
10(1):394.
PMID: 33173029
Panic disorder (PD) is ~2 times more frequent in women. An excessive ventilatory response to CO inhalation is more likely during the premenstrual phase. While ovarian hormones appear important in...

PLoS Biol
. 2019 Apr;
17(4):e2003880.
PMID: 31017885
Because of their intermediate position between supraspinal locomotor centers and spinal circuits, gigantocellular reticular nucleus (GRN) neurons play a key role in motor command. However, the functional contribution of glutamatergic...
