Communication within the interbrachial commissures

(A) The location of stimulation and recording electrodes in the interbrachial commissures.

(B) Typical neural activity recorded in different locations in the interbrachial commissures in response to mechanical stimulation of an arm. Statistical results showed that mechanical stimulation elicit significantly more robust SA activities in closer recording location.

(C) Typical spontaneous activity recorded in two locations within the commissure.

(D and E) Statistical result of propagation velocity (N = 5) (E) Statistical result showed that the delay between two recording site is 2.3 ± 0.31 ms (N = 4). Data represent the mean ± SEM; ∗∗p < 0.01; paired Student’s t test.
