Very ni perspective @CoryMillerMarmo ! I would also add that the reason to specifically increase our Nation's investment in primate research is that this can give us the most insight into primate and human brain efficiency and cognition (as opposed to other animal models).
Here is my new OpED piece about the importance of primate neuroscience research for the future of AI :

The results also speak to the importance of performing multiple analyses on the same dataset (LFP, spiking, temporal, and rate coding). If you stick to only one domain and not the other, you get an incomplete picture of brain function!.

The results also speak to the ongoing debate between 'gamma as prediction errors' (predictive routing) vs. 'gamma as predictions' (a la @martin_a_vinck ). We find evidence for predictive routing, even after accounting for shifts in aperiodic components of the LFP.

We suggest that there could be a functional dissociation between rate coding and temporal coding, where rate coding was more evident late in hierarchical processing and temporal coding (via gamma oscillations) was more evident in early areas of the visual hierarchy.

These results are in contrast to our earlier analysis of this same dataset (Westerberg, Xiong et al.), where we found evidence of predictive processing in spike rates only in very late levels of the hierarchy (e.g., PFC and the highest stages of visual processing).

New paper from the Bastos Lab, led by @EliSennesh! We find ubiquitous predictive processing in the spectral domain (but not rate-coding domain): Gamma oscillations consistently signal prediction errors even in V1!.

Fully agree!.
Not studying animal models would halt basic neuroscience. We don’t have good AI models of animal brains to study and we can’t study human brains at single spike single neuron resolution. Studying the brain using fMRI is like studying the economy from a telescope on the moon.
