Measurements of neuron soma size and density in rat dorsal striatum, nucleus accumbens core and nucleus accumbens shell: differences between striatal region and brain hemisphere, but not sex. Neurosci Lett. 2011 Jan 7 487(2):177-81. doi: 10.1016/j.neulet.2010.10.017. p.180 table 1PubMed ID20951763
Method Abstract: "[Investigators] therefore quantified neuron soma size and density in the dorsal striatum (CPu) as well as the core (AcbC) and shell (AcbS) subregions of the nucleus accumbens to determine whether these anatomical measurements differ by region, hemisphere, or sex in adult Sprague-Dawley rats."
Comments P.178 right column 3rd paragraph: "After determining that neuron soma size and density differed between the CPu, AcbC and AcbS, [investigators] compared these measures between hemisphere and sex in each striatal region using two-way repeated measures ANOVAs (Table 1). [They] found no differences in neuron soma size between sex, hemisphere, or the interaction between sex and hemisphere in the CPu (Fig. 2A), AcbC (Fig. 2B) and AcbS (Fig. 2C)." P.179 right column bottom paragraph: "Regarding lateralization, [investigators] initially included an analysis of lateralization in this study because lateralized sex differences in dopamine levels have been reported in the striatum [ref 26], and because other brain regions exhibit lateralized sexual dimorphisms in neuron size and regional volume [ref 9]. In the rat striatum, however, no interactions between hemisphere and sex were detected (Table 1)." See note beneath table
