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...

Planning of spatially-oriented locomotion following focal brain damage in humans: A pilot study

Hicheur, Halim ; Boujon, Carole ; Wong, Cuebong ; Pham, Quang-Cuong ; Annoni, Jean-Marie ; Bihl, Titus

In: Behavioural Brain Research, 2016, vol. 301, p. 33–42

Motor impairments in human gait following stroke or focal brain damage are well documented. Here, we investigated whether stroke and/or focal brain damage also affect the navigational component of spatially oriented locomotion. Ten healthy adult participants and ten adult brain-damaged patients had to walk towards distant targets from different starting positions (with vision or blindfolded). No...

Comprehension of co-speech gestures in aphasic patients: an eye movement study

Eggenberger, Noëmi ; Preisig, Basil C. ; Schumacher, Rahel ; Hopfner, Simone ; Vanbellingen, Tim ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Bohlhalter, Stephan ; Cazzoli, Dario ; Müri, René M.

In: PLOS ONE, 2016, vol. 11, no. 1, p. e0146583

Co-speech gestures are omnipresent and a crucial element of human interaction by facilitating language comprehension. However, it is unclear whether gestures also support language comprehension in aphasic patients. Using visual exploration behavior analysis, the present study aimed to investigate the influence of congruence between speech and co-speech gestures on comprehension in terms of...

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....

Cue recognition and integration – eye tracking evidence of processing differences in sentence comprehension in aphasia

Schumacher, Rahel ; Cazzoli, Dario ; Eggenberger, Noëmi ; Preisig, Basil ; Nef, Tobias ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Müri, René M.

In: PLoS ONE, 2015, vol. 10, no. 11, p. e0142853

We aimed at further elucidating whether aphasic patients’ difficulties in understanding non-canonical sentence structures, such as Passive or Object-Verb-Subject sentences, can be attributed to impaired morphosyntactic cue recognition, and to problems in integrating competing interpretations.Methods: A sentence-picture matching task with canonical and non-canonical spoken sentences was...

Brain activity during observation and motor imagery of different balance tasks: An fMRI study

Taube, Wolfgang ; Mouthon, Michael ; Leukel, Christian ; Hoogewoud, Henri-Marcel ; Annoni, Jean-Marie ; Keller, Martin

In: Cortex, 2015, vol. 64, p. 102–114

After immobilization, patients show impaired postural control and increased risk of falling. Therefore, loss of balance control should already be counteracted during immobilization. Previously, studies have demonstrated that both motor imagery (MI) and action observation (AO) can improve motor performance. The current study elaborated how the brain is activated during imagination and observation...

Perception of co-speech gestures in aphasic patients: A visual exploration study during the observation of dyadic conversations

Preisig, Basil C. ; Eggenberger, Noëmi ; Zito, Giuseppe ; Vanbellingen, Tim ; Schumacher, Rahel ; Hopfner, Simone ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Bohlhalter, Stephan ; Müri, René M.

In: Cortex, 2015, vol. 64, p. 157–168

Co-speech gestures are part of nonverbal communication during conversations. They either support the verbal message or provide the interlocutor with additional information. Furthermore, they prompt as nonverbal cues the cooperative process of turn taking. In the present study, we investigated the influence of co-speech gestures on the perception of dyadic dialogue in aphasic patients. In...

Impairment of both languages in late bilinguals with dementia of the Alzheimer type

Manchon, Mélanie ; Buetler, Karin ; Colombo, Françoise ; Spierer, Lucas ; Assal, Frédéric ; Annoni, Jean-Marie

In: Bilingualism: Language and Cognition, 2014, vol. 18, no. 01, p. 90–100

Neuropsychological theories raise the question if in late bilinguals with dementia of the Alzheimer type (DAT), the second language (L2) may be more impaired than the first (L1). We compared language performance in different tasks of oral comprehension (semantic and syntactic) and production (naming, repetition and fluency) in L1 and L2 in a group of 13 late proficient bilinguals wit DAT...

Feasibility of a multiple-choice mini mental state examination for chronically critically ill patients

Miguélez, Marta ; Merlani, Paolo ; Gigon, Fabienne ; Verdon, Mélanie ; Annoni, Jean-Marie ; Ricou, Bara

In: Critical Care Medicine, 2014, vol. 42, no. 8, p. 1874–1881

Objectives: Following treatment in an ICU, up to 70% of chronically critically ill patients present neurocognitive impairment that can have negative effects on their quality of life, daily activities, and return to work. The Mini Mental State Examination is a simple, widely used tool for neurocognitive assessment. Although of interest when evaluating ICU patients, the current version is...
