Combined with anti‐Nogo‐A antibody treatment, BDNF did not compensate the extra deleterious motor effect caused by large size cervical cord hemisection in adult macaques

Beaud, Marie‐Laure ; Rouiller, Eric M. ; Bloch, Jocelyne ; Mir, Anis ; Schwab, Martin E. ; Schmidlin, Eric

In: CNS Neuroscience & Therapeutics, 2019, p. cns.13213

In spinal cord injured adult mammals, neutralizing the neurite growth inhibitor Nogo‐A with antibodies promotes axonal regeneration and functional recovery, although axonal regeneration is limited in length. Neurotrophic factors such as BDNF stimulate neurite outgrowth and protect axotomized neurons. Can the effects obtained by neutralizing Nogo‐A, inducing an environment favorable for...

Assessment of the effect of continuous theta burst stimulation of the motor cortex on manual dexterity in non-human primates in a direct comparison with invasive intracortical pharmacological inactivation

Roux, Camille ; Kaeser, Mélanie ; Savidan, Julie ; Fregosi, Michela ; Rouiller, Eric M. ; Schmidlin, Eric

In: European Journal of Neuroscience, 2019, p. -

Non-invasive reversible perturbation techniques of brain output such as continuous theta burst stimulation (cTBS), commonly used to modulate cortical excitability in humans, allow investigation of possible roles in functional recovery played by distinct intact cortical areas following stroke. To evaluate the potential of cTBS, the behavioural effects of this non-invasive transient...

Role of primary motor cortex in the control of manual dexterity assessed via sequential bilateral lesion in the adult macaque monkey: A case study

Savidan, Julie ; Kaeser, Mélanie ; Belhaj-Saïf, Abderraouf ; Schmidlin, Eric ; Rouiller, Eric M.

In: Neuroscience, 2017, vol. 357, p. 303-324

From a case study, we describe the impact of unilateral lesion of the hand area in the primary motor cortex (M1) on manual dexterity and the role of the intact contralesional M1 in long-term functional recovery. An adult macaque monkey performed two manual dexterity tasks: (i) “modified Brinkman board” task, assessed simple precision grip versus complex precision grip, the latter involved a...

Influence of anti-Nogo-A antibody treatment on the reorganization of callosal connectivity of the premotor cortical areas following unilateral lesion of primary motor cortex (M1) in adult macaque monkeys

Hamadjida, Adjia ; Wyss, Alexander F. ; Mir, Anis ; Schwab, Martin E. ; Belhaj-Saif, Abderaouf ; Rouiller, Eric M.

In: Experimental Brain Research, 2012, vol. 223, no. 3, p. 321-340

Following unilateral lesion of the primary motor cortex, the reorganization of callosal projections from the intact hemisphere to the ipsilesional premotor cortex (PM) was investigated in 7 adult macaque monkeys, in absence of treatment (control; n = 4) or treated with function blocking antibodies against the neurite growth inhibitory protein Nogo-A (n = 3). After functional recovery, though...

Follow-up of cortical activity and structure after lesion with laser speckle imaging and magnetic resonance imaging in nonhuman primates

In: Journal of Biomedical Optics, 2011, vol. 16, no. 09, p. 096011

The nonhuman primate model is suitable to study mechanisms of functional recovery following lesion of the cerebral cortex (motor cortex), on which therapeutic strategies can be tested. To interpret behavioral data (time course and extent of functional recovery), it is crucial to monitor the properties of the experimental cortical lesion, induced by infusion of the excitotoxin ibotenic acid. In...

A case of polymicrogyria in macaque monkey: impact on anatomy and function of the motor system

Schmidlin, Eric ; Jouffrais, Christophe ; Freund, Patrick ; Wannier-Morino, Patrizia ; Beaud, Marie-Laure ; Rouiller, Eric M. ; Wannier, Thierry

In: BMC Neuroscience, 2009, vol. 10, p. 155

Background Polymicrogyria is a malformation of the cerebral cortex often resulting in epilepsy or mental retardation. It remains unclear whether this pathology affects the structure and function of the corticospinal (CS) system. The anatomy and histology of the brain of one macaque monkey exhibiting a spontaneous polymicrogyria (PMG monkey) were examined and compared to the brain of normal...

Anti-Nogo-A antibody treatment promotes recovery of manual dexterity after unilateral cervical lesion in adult primates – re-examination and extension of behavioral data

Freund, Patrick ; Schmidlin, Eric ; Wannier, Thierry ; Bloch, Jocelyne ; Mir, Anis ; Schwab, Martin E. ; Rouiller, Eric M.

In: European Journal of Neuroscience, 2009, vol. 29, no. 5, p. 983 - 996

In rodents and nonhuman primates subjected to spinal cord lesion, neutralizing the neurite growth inhibitor Nogo-A has been shown to promote regenerative axonal sprouting and functional recovery. The goal of the present report was to re-examine the data on the recovery of the primate manual dexterity using refined behavioral analyses and further statistical assessments, representing secondary...

Progressive plastic changes in the hand representation of the primary motor cortex parallel incomplete recovery from a unilateral section of the corticospinal tract at cervical level in monkeys

Schmidlin, Eric ; Wannier, Thierry ; Bloch, Jocelyne ; Rouiller, Eric M.

In: Brain Research, 2004, vol. 1017, p. 172-182

After a sub-total hemisection of the cervical cord at level C7/C8 in monkeys, a paralysis of the homolateral hand is rapidly followed by an incomplete recovery of manual dexterity, reaching a plateau after about 40–50 days, whose extent appears related to the size of the lesion. During a few days after the lesion, the hand representation in the contralateral motor cortex disappeared, replaced...
