Ruffieux, N. ; Colombo, Françoise ; Gentaz, E. ; Annoni, Jean-Marie ; Chouiter, Leila ; Roulin Hefti, S. ; Ruffieux, A. ; Bihl, T.

In: Applied Neuropsychology: Child, 2017, vol. 6, no. 2, p. 180–188

The objective of this case study was to describe the neuropsychological rehabilitation of a 16-year-old patient who presented a Cerebellar Cognitive Affective Syndrome (CCAS) following a bilateral cerebellar hemorrhage. The patient presented severe and diffuse cognitive deficits, massive behavioral disorders, and emotion regulation difficulties. The cognitive rehabilitation was performed in...

Partly segregated cortico-subcortical pathways support phonologic and semantic verbal fluency: A lesion study

Chouiter, Leila ; Holmberg, Josefina ; Manuel, Aurelie L. ; Colombo, Françoise ; Clarke, Stephanie ; Annoni, Jean-Marie ; Spierer, Lucas

In: Neuroscience, 2016, vol. 329, p. 275–283

Verbal fluency refers to the ability to generate as many words as possible in a limited time interval, without repetition and according to either a phonologic (each word begins with a given letter) or a semantic rule (each word belongs to a given semantic category). While current literature suggests the involvement of left fronto-temporal structures in fluency tasks, whether the same or...

Experience-based auditory predictions modulate brain activity to silence as do real sounds

Chouiter, Leila ; Tzovara, Athina ; Dieguez, Sebastian ; Annoni, Jean-Marie ; Magezi, David ; De Lucia, Marzia ; Spierer, Lucas

In: Journal of Cognitive Neuroscience, 2015, vol. 27, no. 10, p. 1968–1980

Interactions between stimuli's acoustic features and experience-based internal models of the environment enable listeners to compensate for the disruptions in auditory streams that are regularly encountered in noisy environments. However, whether auditory gaps are filled in predictively or restored a posteriori remains unclear. The current lack of positive statistical evidence that internal...

High and low stimulus-driven conflict engage segregated brain networks, not quantitatively different resources

Chouiter, Leila ; Dieguez, Sebastian ; Annoni, Jean-Marie ; Spierer, Lucas

In: Brain Topography, 2014, vol. 27, no. 2, p. 279–292

Task-irrelevant information is constantly present in our environment and may interfere with the processing of the information necessary to achieve goal-directed behavior. While task goals determine which information must be suppressed, the demand for inhibitory control depends on the strength of the interference induced by incoming, task-irrelevant information. Whether the same or distinct...

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...

inter- and intrahemispheric dissociations in ideomotor apraxia: a large-Scale lesion–symptom mapping study in subacute brain-damaged patients

Manuel, Aurelie L. ; Radman, Narges ; Mesot, Delphine ; Chouiter, Leila ; Clarke, Stephanie ; Annoni, Jean-Marie ; Spierer, Lucas

In: Cerebral Cortex, 2012, p. -

Pantomimes of object use require accurate representations of movements and a selection of the most task-relevant gestures. Prominent models of praxis, corroborated by functional neuroimaging studies, predict a critical role for left parietal cortices in pantomime and advance that these areas store representations of tool use. In contrast, lesion data points to the involvement of left inferior...
