Excited to share that the collaborative work with @mhahn29 just came out at @NatureNeuro . nature.com/articles/s41593-0…

A unifying theory explains seemingly contradictory biases in perceptual estimation

Nature Neuroscience - Despite a long history of studying perceptual biases in neuroscience, many of the biases remain difficult to explain and even appear to be contradictory. The authors propose a...

Second, biases reported in orientation perception can be explained by an efficient neural code together with a prior distribution that is nearly uniform.

New paper from a fun and exciting collaboration with the Brandon Lab (@markpaulbrandon @AjabiZaki @atkeinath) (nature.com/articles/s41586-0…)

Population dynamics of head-direction neurons during drift and reorientation

Nature - Mice maintain the memory of previous associations between head direction neurons and allocentric cues and this influences the internal head direction representation.

(19/n) Its representation should be more modifiable compared to the cortex, which may maintain multiple hypotheses of the world. The long-term memory in the cortex can correct the thalamus if needed.

(20/n) According to this view, it makes sense to have multiple (rather than one) copies of head direction representation. This provides one conceptual framework to think about why there are so many brain areas in the mammalian brain that encode head direction.
