Note that 62.7 IT in addition to a 37.three thalamic input yields an extremely close size frequency distribution match for striatonigral neurons. In the case of striato-GPe neurons, 54.2 PT, 20 IT and 25.eight thalamic yields a close approximation for the axospinous input to this neuron type.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptJ Comp Neurol.

Note that even though VGLUT2+ axospinous terminals show much more variability than do VGLUT1+ axospinous terminals in the table, this reflects within-group variability for the means, and not the all round range of variability in terminal size for VGLUT1+ and VGLUT2+ axospinous synaptic terminals. The truth is, the pooled data shows the array of variation to be larger for VGLUT1+ than VGLUT2+ axospinous terminals, with numerous VGLUT1+ axospinous terminals larger than widespread for VGLUT2+ axospinous terminals.J Comp Neurol.
