2. Medicine. A representation of the structure or function of a nerve obtained by radiological techniques, electrical recording, etc.

1969 Science 4 Apr. 76/1 The neurogram of the cervical portion of the phrenic nerve, recorded with bipolar platinum electrodes, was used to indicate efferent respiratory activity.

1975 Amer. Jrnl. Physiol. 228 331 One hindlimb, kidney, gracilis muscle, and paw were perfused at constant flow, and neurograms were obtained from renal sympathetic fibers.
