Age-related differences in corticospinal excitability during observation and motor imagery of balance tasks

Mouthon, Audrey A. ; Ruffieux, Jan ; Keller, Martin ; Taube, Wolfgang

In: Frontiers in Aging Neuroscience, 2016, vol. 8, p. -

Postural control declines across adult lifespan. Non-physical balance training has been suggested as an alternative to improve postural control in frail/immobilized elderly people. Previous studies showed that this kind of training can improve balance control in young and older adults. However, it is unclear whether the brain of young and older adults is activated differently during mental...

State dependency of inhibitory control performance: an electrical neuroimaging study

De Pretto, Michael ; Sallard, Etienne ; Spierer, Lucas

In: European Journal of Neuroscience, 2016, vol. 44, no. 2, p. 1826–1832

Behavioral and brain responses to stimuli not only depend on their physical features but also on the individuals' neurocognitive states before stimuli onsets. While the influence of pre-stimulus fluctuations in brain activity on low-level perceptive processes is well established, the state dependency of high-order executive processes remains unclear. Using a classical inhibitory control...

Enhancing frontal top-down inhibitory control with Go/NoGo training

Hartmann, Lea ; Sallard, Eienne ; Spierer, Lucas

In: Brain Structure and Function, 2016, vol. 221, no. 7, p. 3835–3842

Whether and how the capacity to inhibit cognitive and motor processes can be trained and the underlying neuroplastic mechanisms remain unclear. Using electrical neuroimaging methods, we investigated how inhibitory control training regimens can be designed to enhance frontal top-down inhibition processes. We trained participants with a Go/NoGo task in which the stimulus–response mapping...
