This is excellent and has me re-evaluating my well-intended (but unwittingly harmful) efforts at precision in collecting demographic data from participants in experiments. [h/t @steveharoz.com]

This is a great organization that is committed to supporting early-career clinician scientists. Not just for MD/PhDs! Straight MDs, DOs, and even veterinarians. Please share with anyone you know who might be eligible.

This week we completed an elusive measurement: the flat fielding function of the wide-angle camera on our wearable light-logger. To do so, we visited the Fels Planetarium at the @franklininstitute.bsky.social. 1/6

In honor of Mel Brooks turning 100, I would like to again note that young Dr. Frankenstein gives a pretty good brainstem lecture.

Peak retired academic moment. 1. One of those emails: Are you the R Watt who wrote xxxxxx? 2. Nope, but it sounds vaguely interesting. Wonder what they found. 3. Google - read it and discover that I did write it.

Very cool. The white matter connectivity of early visual cortex recapitulates the polar angle variation of retinal structure. One look at this figure and you know you are in the world of retinal meridians and that Marisa Carrasco will be making an appearance.
A portion of Figure 3a of Amorosino et al that has the signature of polar angle retinal variation.

There’s an interesting lawsuit out of Connecticut I’ve been following that rests on the question of whether darkness — yes, darkness, the primordial Erebus himself— is a natural resource. Here’s why that’s potentially a big deal.

We are building a gaze calibration apparatus. The observer positions their head at the center of a large hemisphere. They fixate on LEDs displayed at 3 foot distance at various visual angles while we record from a pupil camera. Today, I found the perfect structure to use for the hemisphere.

I study how perception is altered in neurologic disease. In particular, why some visual experiences are painful (i.e., produce photophobia), especially for people with migraine. These studies use custom devices for presenting stimuli and measuring the environment. Here’s a look at some of these.
