Distant heterotopic callosal connections to premotor cortex in non-human primates

Lanz, Florian ; Moret, Véronique ; Ambett, R. ; Cappe, Céline ; Rouiller, Eric M. ; Loquet, Gérard

In: Neuroscience, 2017, vol. 344, p. 56–66

Cortico-cortical connectivity has become a major focus of neuroscience in the last decade but most of the connectivity studies focused on intrahemispheric circuits. Little has been reported about information acquired and processed in the premotor cortex and its functional connection with its homotopic counterpart in the opposite hemisphere via the corpus callosum. In non-human primates...

Whole-scalp EEG mapping of somatosensory evoked potentials in macaque monkeys

Gindrat, Anne-Dominique ; Quairiaux, Charles ; Britz, Juliane ; Brunet, Denis ; Lanz, Florian ; Michel, Christoph M. ; Rouiller, Eric M.

In: Brain Structure and Function, 2015, vol. 220, no. 4, p. 2121–2142

High-density scalp EEG recordings are widely used to study whole-brain neuronal networks in humans non-invasively. Here, we validate EEG mapping of somatosensory evoked potentials (SSEPs) in macaque monkeys (Macaca fascicularis) for the long-term investigation of large-scale neuronal networks and their reorganisation after lesions requiring a craniotomy. SSEPs were acquired from 33 scalp...

Refined methodology for implantation of a head fixation device and chronic recording chambers in non-human primates

Lanz, Florian ; Lanz, X. ; Scherly, A. ; Moret, Véronique ; Gaillard, A. ; Gruner, P. ; Hoogewoud, Henri-Marcel ; Belhaj-Saif, Abderraouf ; Loquet, Gérard ; Rouiller, Eric M.

In: Journal of Neuroscience Methods, 2013, vol. 219, no. 2, p. 262–270

The present study was aimed at developing a new strategy to design and anchor custom-fitted implants, consisting of a head fixation device and a chronic recording chamber, on the skull of adult macaque monkeys. This was done without the use of dental resin or orthopedic cement, as these modes of fixation exert a detrimental effect on the bone. The implants were made of titanium or tekapeek and...
