The human-neuroscience N2pc marker of covert and internal attention co-occurs with spatial biases in microsaccades, 200-300 ms after prompted to shift attention. (How) are these empirical phenomena related? Check it out in the latest work led by @baiweiliu.bsky.social:

Microsaccades strongly modulate but do not directly cause the EEG N2pc marker of spatial attention

Researchers often study human attention using microsaccades and the N2pc EEG marker, but it is unclear to what extent microsaccades contribute to N2pc. This study shows that microsaccades modulate N2p...

The manuscript also includes practical analytical tips for controlling swap errors, as well as a new non-parametric method for estimating biases.

Who doesn't like a good model of the brain? Yet, from simple regression to neural nets, some limitations keep popping up (e.g., overfitting) @mjwolff.bsky.social & I saw some cool but puzzling data, ran a quick analysis & found one such limitation: model mimicry. Now in #naturecommunications &🧵below

Model mimicry limits conclusions about neural tuning and can mistakenly imply unlikely priors
