Balanced bilinguals favor lexical processing in their opaque language and conversion system in their shallow language

Buetler, Karin A. ; Rodríguez, Diego de León ; Laganaro, Marina ; Müri, René ; Nyffeler, Thomas ; Spierer, Lucas ; Annoni, Jean-Marie

In: Brain and Language, 2015, vol. 150, p. 166–176

Referred to as orthographic depth, the degree of consistency of grapheme/phoneme correspondences varies across languages from high in shallow orthographies to low in deep orthographies. The present study investigates the impact of orthographic depth on reading route by analyzing evoked potentials to words in a deep (French) and shallow (German) language presented to highly proficient bilinguals....

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...

Electrical neuroimaging during auditory motion aftereffects reveals that auditory motion processing is motion sensitive but not direction selective

Magezi, David A. ; Buetler, Karin A. ; Chouiter, Leila ; Annoni, Jean-Marie ; Spierer, Lucas

In: Journal of Neurophysiology, 2013, vol. 109, no. 2, p. 321-331

Following prolonged exposure to adaptor sounds moving in a single direction, participants may perceive stationary-probe sounds as moving in the opposite direction [direction-selective auditory motion aftereffect (aMAE)] and be less sensitive to motion of any probe sounds that are actually moving (motion-sensitive aMAE). The neural mechanisms of aMAEs, and notably whether they are due to...
