Ia Proprioceptive Afferents Make Functional Connections with Motor Neurons in Er81EWS-Pea3 Mutants (A and B) Representative traces from intracellular recordings measuring Ia afferent monosynaptic input to quadriceps motor neurons evoked by suprathreshold stimulation of the quadriceps nerve in wild-type (A) and Er81EWS-Pea3/− mutant (B) animals. (C) Average monosynaptic amplitudes (± standard error of the mean) from all recorded cells (wild-type, n = 11; mutant, n = 8). (20 KB CDR).
