Feasibility and main mechanisms underlying in vivo ultrasound neurostimulation of the ventral nerve cord's giant axons of Lumbricus Terrestris

Several works carried out these last years have demonstrated the ability of ultrasound (US) to activate neurons at a systemic level. However, no complete description of the biophysical mechanisms involved in this phenomenon has been validated so far. In order to identify experimentally these mechanisms, we here present an in vivo study of the stimulating effects of US exposures on the ventral nerve cord of the earthworm (Lumbricus Terrestris).
