TL;DR: Differences in cortical areas of the human, rat and mouse probably indicate the evolutionary adaptation of excitatory and inhibitory circuits to particular functions.

TL;DR: For all morphological parameters analyzed, spines exhibited a continuum of variability, without clearly distinguishable subtypes of spines or clear dependence of their morphologies on their distance to the soma.

TL;DR: These organelles are cellular “antennae” critically required to modulate ALNP behavior, and selective targeting of Shh machinery to primary cilia confers to ALNPs the ability to differentially respond to Shh mitogenic signals compared to neighboring cells.

TL;DR: The results show the existence of cholinergic neuron–astrocyte signaling and suggest that astrocytes are a target of axonal inputs from different brain areas.

TL;DR: 5-HTT knock-out mice reveal a nearly complete absence of 5-HT in the cerebral cortex by immunohistochemistry, and of barrels, both at P7 and adulthood, while VMAT2 ko mice, completely lacking activity-dependent vesicular release of monoamines including 5- HT, also show a complete lack of 4-HT, but display largely normal barrel fields.
