    Surround inhibition can instantly be modulated by changing the attentional focus

    Kuhn, Yves-Alain ; Keller, Martin ; Lauber, Benedikt ; Taube, Wolfgang

    In: Scientific Reports, 2018, vol. 8, no. 1, p. 1085

    To further investigate the mechanism of surround inhibition (SI) and to determine whether adopting different attentional strategies might have an impact on the modulation of SI, the effects of adopting an external (EF) or internal focus of attention (IF) on SI and motor performance were investigated. While performing an index flexion with either an EF or IF, transcranial magnetic stimulation...

    Adopting an external focus of attention alters intracortical inhibition within the primary motor cortex

    Kuhn, Yves-Alain ; Keller, Martin ; Ruffieux, Jan ; Taube, Wolfgang

    In: Acta Physiologica, 2017, vol. 220, no. 2, p. 289–299

    Although it is well established that an external (EF) compared to an internal (IF) or neutral focus of attention enhances motor performance, little is known about the underlying neural mechanisms. This study aimed to clarify whether the focus of attention influences not only motor performance but also activity of the primary motor cortex (M1) when executing identical fatiguing tasks of the...
