3D Region Atlas
Add a region above and what it does appears here, stacked by layer: the cortex at the top, the limbic midbrain beneath it, the reptilian core at the bottom, and the Brodmann areas in a block of their own.
The three layers are MacLean's triune scheme. It stacks a brain map tidily and it is poor evolutionary history — the “reptilian” structures are not reptilian, and every layer here is present in every vertebrate with a brain. The grouping is a way of reading the map, not a claim about how it was built.
How thickly each receptor sits in each region, from two open sources: in vivo PET, one group-average tracer map per receptor or transporter, averaged over each AAL region; and ex vivo autoradiography, absolute densities in fmol/mg protein from post-mortem cortex, mapped onto the regions area by area. The two measure different things and are never put on one axis. Click a region’s name and it lights up in the viewports above as a highlighted region like any other; whatever is highlighted above lights its bar here in the same colour. Pick a receptor and what binds it and what it sits in are drawn beneath the chart, with its source, tracer, sample and caveat under those.
