JNP Micro Podcasts: Modulation of corticospinal excitability during vibration

In this episode,  Lydiane Lauzier of Université du Québec à Chicoutimi discusses the recently published article “Variation of corticospinal excitability during kinesthetic illusion induced by musculotendinous vibration.”

 

New and Noteworthy:

The modulation of corticospinal excitability when perceiving a vibration (VIB)-induced kinesthetic illusion evolves dynamically over time. This modulation might be linked to the delayed occurrence and progressive increase in strength of the illusory perception in the first seconds after VIB start. Different spinal/cortical mechanisms could be at play during VIB, depending on the tested muscle, presence/absence of an illusion, and the specific timing at which corticospinal drive is tested pre/post VIB.
