Cover picture: An amplitude modulation-sensitive neuron in the electrosensory lateral line lobe (ELL) of weakly electric fish, Gymnarchus. The neuron was labeled with biocytin using the in vivo whole-cell recording and labeling technique. The intense labeling of the neuron revealed its large dendritic field in the molecular layer of the ELL and projection terminals (not shown) in the midbrain nucleus, torus semicircularis, which is at the distance of 7 mm. Some of these neurons were sensitive to small (0.5%) incremental changes in electrosensory stimuli. More than 100 neurons were recorded physiologically and identified anatomically, revealing parallel processing of two essential sensory cues for an electrical behavior, the jamming avoidance response. For details, see the article by Kawasaki and Guo, in this issue (pages 7599-7611).
