For those curious, I found this source: http://prefrontal.org/files/posters/Bennett-Salmon-2009.pdf (Bennet et al. 2009: Neural correlates of interspecies perspective taking in the post-mortem Atlantic Salmon: An argument for multiple comparisons correction)

Essentially it’s using a dead salmon as a lone control to argue that fMRI studies should be more rigorous in how they control for random noise.

There’s been some planning and minor media to-do about the 250th anniversary. For example, IIRC there’s a picture of Kid Rock in an incredibly gaudy suit with “250” written on it, taken in the oval office next to Trump.
