Age-related differences in cortical and subcortical activities during observation and motor imagery of dynamic postural tasks: an FMRI study

Mouthon, Audrey ; Ruffieux, Jan ; Mouthon, Michael ; Hoogewoud, Henri-Marcel ; Annoni, Jean-Marie ; Taube, Wolfgang

In: Neural Plasticity, 2018, p. -

Age-related changes in brain activation other than in the primary motor cortex are not well known with respect to dynamic balance control. Therefore, the current study aimed to explore age-related differences in the control of static and dynamic postural tasks using fMRI during mental simulation of balance tasks. For this purpose, 16 elderly (72 ± 5 years) and 16 young adults...

Decision-making in multiple sclerosis patients: a systematic review

Neuhaus, Mireille ; Calabrese, Pasquale ; Annoni, Jean-Marie

In: Multiple Sclerosis International, 2018, p. -

Background. Multiple sclerosis (MS) is frequently associated with cognitive and behavioural deficits. A growing number of studies suggest an impact of MS on decision-making abilities. The aim of this systematic review was to assess if (1) performance of MS patients in decision-making tasks was consistently different from controls and (2) whether this modification was associated with cognitive...

Behavioral and electrophysiological signatures of word translation processes

Jost, Lea B. ; Radman, Narges ; A.Buetler, Karin ; Annoni, Jean-Marie

In: Neuropsychologia, 2018, vol. 109, p. 245–254

Translation is a demanding process during which a message is analyzed, translated and communicated from one language to another. Despite numerous studies on translation mechanisms, the electrophysiological processes underlying translation with overt production remain largely unexplored. Here, we investigated how behavioral response patterns and spatial-temporal brain dynamics differ in a...

Balance training reduces brain activity during motor simulation of a challenging balance task in older adults: an fMRI study

Ruffieux, Jan ; Mouthon, Audrey ; Keller, Martin ; Mouthon, Michaël ; Annoni, Jean-Marie ; Taube, Wolfgang

In: Frontiers in Behavioral Neuroscience, 2018, vol. 12, p. -

Aging is associated with a shift from an automatic to a more cortical postural control strategy, which goes along with deteriorations in postural stability. Although balance training has been shown to effectively counteract these behavioral deteriorations, little is known about the effect of balance training on brain activity during postural tasks in older adults. We, therefore, assessed...
