Orientation preferences along tangential electrode recording tract in grasshopper mice. (A) Example extracellular recordings along reconstructed along tangential recording tract. Nissl stain of fixed brain slice with microelectrode current lesion (asterisk) shown in inset. Separate single unit recordings shown along tract with example action potential waveforms and oriented bars depicting orientation preferences. (B) Relationship of absolute value of orientation preference difference and distance between recordings within single penetrations.
