Alterations in the cortical control of standing posture during varying levels of postural threat and task difficulty

Congratulations to Martin Keller, Gonazalo Márquez, Wolfgang Taube and Cluster Members Craig D.Tokuno and Mark Carpenter on the publication of their paper "Alterations in the cortical control of standing posture during varying levels of postural threat and task difficulty" in the Journal of Neurophysiology. 

Cortical excitability increases during the performance of more difficult postural tasks. However, it is possible that changes in postural threat associated with more difficult tasks may in themselves lead to alterations in the neural strategies underlying postural control. Therefore, the purpose of this study was to examine whether changes in postural threat are responsible for the alterations in corticospinal excitability and short-interval intracortical inhibition (SICI) that occur with increasing postural task difficulty.
