Generation of New Neurons in Dorsal Root Ganglia in Adult Rats after Peripheral Nerve Crush Injury

Figure 1

Example of the toluidine blue stained micrographs of reference (a) and counting (b) sections from which neurons numbers are estimated using the physical disector. All nuclear profiles are recognized in the reference section (yellow circles); nuclear profiles that do not appear in the counting section are counted (green circles). The nuclei of cells that appear in both the counting and reference sections are not counted (red circles). Bars = 50 µm.
