Oddbean new post about login | logout wow, this paper totally destroys the current mechanistic interpretations of circular dynamics in neural population data: https://biorxiv.org/content/10.1101/2023.09.11.557230v1 One thing they don't talk about is that any state space representation of discrete movements will also produce rotations...
@40eabf52 Nifty! Overall, our findings suggest that rotational dynamics and travelling waves are the same phenomena, which requires reevaluation of the previous interpretations where they were considered as separate entities. In terms of destroys, I suspect you are referring to this? It is important to keep in mind that the model of the rotations in the data is not a model of how the motor cortex generates volitional movements.
