Glomerular distribution following chronic Triton X-100 treatment and recovery. Using the zebrafish glomerular map to identify individual glomeruli, each glomerulus was designated as present (+), absent (−), or scattered, but incomplete (s) in 4 zebrafish from each group. In controls, all 22 glomeruli were observed. Chronic treated fish showed a dramatic decrease in glomerular innervation. Glomeruli located in the medial and dorsal regions were lacking more glomeruli than the other regions while the lateral region maintained the most innervation. Although the degree of innervation and recovery varied slightly between fish, following cessation of treatment, the majority of glomeruli were again observed in all regions of the olfactory bulb.
