Practice-induced functional plasticity in inhibitory control interacts with aging

Hartmann, Lea ; Wachtl, Laura ; Lucia, Marzia de ; Spierer, Lucas

In: Brain and Cognition, 2019, vol. 132, p. 22–32

Inhibitory control deficits represent a key aspect of the cognitive declines associated with aging. Practicing inhibitory control has thus been advanced as a potential approach to compensate for age-induced neurocognitive impairments. Yet, the functional brain changes associated with practicing inhibitory control tasks in older adults and whether they differ from those observed in young...

Spatiotemporal brain dynamics underlying attentional bias modifications

Sallard, Etienne ; Hartmann, Lea ; Ptak, Radek ; Spierer, Lucas

In: International Journal of Psychophysiology, 2018, vol. 130, p. 29–39

Exaggerated attentional biases toward specific elements of the environment contribute to the maintenance of several psychiatric conditions, such as biases to threatening faces in social anxiety. Although recent literature indicates that attentional bias modification may constitute an effective approach for psychiatric remediation, the underlying neurophysiological mechanisms remain unclear....

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...
