Sure maybe there are some stragglers. But you would be surprised how strict a rate coding only argument is, such that I don’t even think it is an argument. That’s my point. But just because you say rates matter does mean “only rates matter”. Temporal coding doesn’t deny rates can code information.

Why does spikes vs LFP have to be framed as “rates only” vs “oscillations”? I also don’t think anyone really believes in the “rates only” idea any longer. The temporal pattern/sequence of spikes can encode information, of which rhythmic spike patterns are one type, and low-dimensional one at that.

The two conferences attract almost non-overlapping audiences. Your PhD work for example would be something you could easily find at Cosyne, but not at CNS which is more cognitive neuroscience focused.

Yeah both are happening right now. Cosyne was pushed a bit forward this year.

Well it is a cute idea to suggest that we are as unconfident about spikes as we are the LFP. But I would like to hear your mechanistic explanation for LFP entrainment. Keep in mind the LFP is roughly +/- 2mV in amplitude (broadband amplitude), and the resting state of the neuron is around -70 mV.

Sure, it might be easier to imagine how the brain orchestrates neural activity by casting into a low-dimensional space, such as the LFP, but that doesn’t prove the LFP isn’t the end of a casual chain.

Well at its lowest level wouldn’t you say neurons communicate by changing each others conductance? To me at least, resonance isn’t so much about communication as it is signal amplification, which is then signal transmission but not necessarily signal processing (communication = encoding & decoding)

True, but still not bilaterally symmetric.

That makes sense. I think most people would jump to cite Phineas Gage as an example of severe deficits from a unilateral frontal lesion. But I have recently learned that it is likely much of what we have been taught about his behavioral changes maybe more lore than unequivocal fact.

I guess what he means is that they are picking up spikes (action potentials) and not just LFP (field potentials), but the way he says it is not typical. You should be able to tell immediately if you have spikes or not just by looking and listening to your recording.

Their bluesky account might be gone, but the Sworn Enemies list lives on… www.theseedsofscience.org/sworn-enemies

I am curious if any of the 307 “Gardeners” listed on their website know what they signed up for.

For podcasts I can recommend You Are Not So Smart and Revisionist History.
