Check out my new work with David Brainard & @GKAguirre! We measured chromatic contrast response functions and show that our quadratic model is able to predict fMRI responses in V1 to a wide range of stimuli. We examine how V1 chromatic sensitivity changes with eccentricity.

New work from Ben Chin (@perceptchin) and @johannesburge

[Ben Chin @perceptchin]

Mystery unraveled! I’m excited to share my work with @johannesburge now on @biorxivpreprint. We explain a previously reported but poorly understood visual illusion: an anomalous variant of the well-known Pulfrich effect (1/4)https://t.co/ozHK8paxLT

@JesseGomezBrain The chickens should be figure 1 in every Neuro textbook.

All classes should have a meme assignment.

We used altered-reality to induce the McCollough Effect. The paper is out today in Vision Research.

✨ Check out my latest paper in Vision Research ✨

We measured discrimination sensitivity and visual preference toward naturalistic noise stimuli varying in their 1/f amplitude spectra in space *and* time

New preprint from my PhD work, together w/ @noahbenson, @carrasco_lab & @JonWinawer. We show that radial asymmetries are not just inherited from cones but become increasingly larger in early visual processing stages + a new RGC observer model linking RGC sampling to behavior!

new preprint 🥳 with the dream team of @stanford_vpnl, @cvnlab, and @dfinz: holistic face recognition is an emergent phenomenon of spatial integration in face-selective regions https://t.co/fb6kgBo0jT

Which Pokemon would make the best phd supervisor? My vote is for Slowking. He's an associate prof (2nd evolution) so he's still hustling, but his sweet regalia suggests he has a prestigious position. Plus he's psychic so he would be empathetic. Have I given this too much thought?

[Katie Tregillus @KatieTregillus]

A recent pre-print from our lab showing multi-day adaptation to tinted lenses led to more immediate perceptual adjustment. #visionscience
