By disentangling morphological and synaptic contributions, we find that human neurons are not just scaled-up rat neurons.
Instead, dendritic architecture and NMDA nonlinearities jointly make human neurons more functionally complex, setting them apart from rat neurons. (7/13)
[Embedded chart, panel "E":]
Title: (panel E, part of a larger figure)
Y-axis: "Functional Complexity Index" (0.1 to 0.5)
X-axis categories: "Rat L2/3" and "Human L2/3"
Data: Rat L2/3 box plot centered at 0.1877; Human L2/3 box plot centered at 0.4294, significance bracket marked "****" between the two groups. Below each box plot, a traced neuron morphology drawn to scale (300 µm scale bar shown): the rat L2/3 neuron (orange) is visibly smaller/less branched than the human L2/3 neuron (teal/green), which has a much larger, more elaborately branched dendritic tree.

A neuroscience research thread (thread part 7/13) with an embedded scientific figure comparing dendritic complexity between rat and human layer 2/3 pyramidal neurons, including actual traced neuron morphology drawings alongside a quantitative box-plot comparison.
