Pablo Rudomin
Pedro Pablo Rudomín Zevnovaty, Mexican neurophysiologist (Ciudad de Mexico 15 June 1934 – Son of Jewish Russian immigrants Authored over 122 papers Suggested that presynaptic inhibition of muscle spindles and tendinous receptors afferent terminals are mediated by last order distinct interneurons Showed that aortic and sinus nerve afferent terminals are not influenced by presynaptic mechanism (1968) With Burke & Zajac described a second form of posttetanic potentiation (1976) With H.
