Fig. 3. Number of choline acetyltransferase (ChAT)-immunostained neurons from the L4 spinal level from animals receiving intrathecal saline (open bars) or AF64-A (2 nmol in light gray, 5 nmol in dark gray, 15 nmol in striped bars). Data are presented as median (dark lines) and 25th and 75th percentiles (vertical extent of bars) of 4–5 animals. * P < 0.001 versus saline group.
