1.
Banerjee R, Kaptan M, Tinnermann A, Khatibi A, Dabbagh A, Buchel C, et al.
bioRxiv . 2025 Jan; PMID: 39829895
Functional magnetic resonance imaging (fMRI) of the spinal cord is relevant for studying sensation, movement, and autonomic function. Preprocessing of spinal cord fMRI data involves segmentation of the spinal cord...

Mobarak-Abadi M, Mahmoudi-Aznaveh A, Dehghani H, Zarei M, Vahdat S, Doyon J, et al.
Front Psychiatry . 2024 Jul; 15:1323109. PMID: 39006826
Background And Purpose: There are distinct challenges in the preprocessing of spinal cord fMRI data, particularly concerning the mitigation of voluntary or involuntary movement artifacts during image acquisition. Despite the...

Vahdat S, Landelle C, Lungu O, De Leener B, Doyon J, Baniasad F
Res Sq . 2024 Feb; PMID: 38352433
Simultaneous functional magnetic resonance imaging (fMRI) of the spinal cord and brain represents a powerful method for examining both ascending sensory and descending motor pathways in humans . However, its...

Farrens A, Vahdat S, Sergi F
J Neurosci . 2023 Mar; 43(19):3520-3537. PMID: 36977577
Dynamic adaptation is an error-driven process of adjusting planned motor actions to changes in task dynamics (Shadmehr, 2017). Adapted motor plans are consolidated into memories that contribute to better performance...
5.
Khatibi A, Vahdat S, Lungu O, Finsterbusch J, Buchel C, Cohen-Adad J, et al.
Neuroimage . 2022 Mar; 253:119111. PMID: 35331873
The spinal cord is important for sensory guidance and execution of skilled movements. Yet its role in human motor learning is not well understood. Despite evidence revealing an active involvement...

Landelle C, Lungu O, Vahdat S, Kavounoudias A, Marchand-Pauvert V, De Leener B, et al.
Neuroimage . 2021 Nov; 245:118684. PMID: 34732324
Most of our knowledge about the human spinal ascending (sensory) and descending (motor) pathways comes from non-invasive electrophysiological investigations. However, recent methodological advances in acquisition and analyses of functional magnetic...

Choy M, Dadgar-Kiani E, Cron G, Duffy B, Schmid F, Edelman B, et al.
Neuron . 2021 Oct; 110(2):221-236.e4. PMID: 34706219
Repeated seizure activity can lead to long-term changes in seizure dynamics and behavior. However, resulting changes in brain-wide dynamics remain poorly understood. This is due partly to technical challenges in...

Vahdat S, Pendharkar A, Chiang T, Harvey S, Uchino H, Cao Z, et al.
Sci Adv . 2021 Aug; 7(33). PMID: 34380610
Poststroke optogenetic stimulations can promote functional recovery. However, the circuit mechanisms underlying recovery remain unclear. Elucidating key neural circuits involved in recovery will be invaluable for translating neuromodulation strategies after...

Babadi S, Vahdat S, Milner T
J Neurosci . 2021 Jun; 41(26):5667-5676. PMID: 34088798
As we learn to perform a motor task with novel dynamics, the central nervous system must adapt motor commands and modify sensorimotor transformations. The objective of the current research is...

Vahdat S, Khatibi A, Lungu O, Finsterbusch J, Buchel C, Cohen-Adad J, et al.
PLoS Biol . 2020 Jul; 18(7):e3000789. PMID: 32614823
In the absence of any task, both the brain and spinal cord exhibit spontaneous intrinsic activity organised in a set of functionally relevant neural networks. However, whether such resting-state networks...
