Extended Data Fig. 2: Transmission of vibration within the hindlimb tissue.
From: Emergence of a brainstem somatosensory tonotopic map for substrate vibration
a, Amplitude spectra measurement of transmitted vibration along the 7 locations of the hindlimb of an anaesthetized mouse with a laser doppler vibrometer. From the bottom right to the top left, stimulation was placed at the 7 locations of the hindlimb, from the toe to the thigh. b, Amplitude spectra measurement of transmitted vibration with higher amplitude along the 7 locations of the hindlimb of an anaesthetized mouse. Top, stimulation was placed at the toe. Bottom, stimulation was placed at the heel. c, Amplitude spectra measurement of transmitted vibration along the 5 along the fibula freshly dissected from an euthanized mouse. Top, stimulation was placed at the toe. Bottom, stimulation was placed at the heel. d, Signal intensity of different frequency components were obtained ex vivo at the base of fibula in the dissected hindlimb, where the Pacinian corpuscle mainly located. Top, stimulation was placed at the toe. Bottom, stimulation was placed at the heel. Data were from 2 animals and the trials were repeated 5 times. Error bars represent S.E.M.
