Stimulus reward value interacts with training-induced plasticity in inhibitory control

Pretto, Michael De ; Hartmann, Lea ; Garcia-Burgos, David ; Sallard, Etienne ; Spierer, Lucas

In: Neuroscience, 2019, vol. 421, p. 82–94

Training inhibitory control, the ability to suppress motor or cognitive processes, not only enhances inhibition processes, but also reduces the perceived value and behaviors toward the stimuli associated with the inhibition goals during the practice. While these findings suggest that inhibitory control training interacts with the aversive and reward systems, the underlying spatio-temporal...

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...

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...
