Neuro-oscillatory models of cortical speech processing In this review, we examine computational models that explore the role of neural oscillations in speech perception, spanning from early auditory proces…

When you are debugging and this song comes up three times on your playlist, you can't help but wonder, "Why do they scream OREGANO??"

Sure, in the end, everything is an RNN ;)

Mongillo's model indeed requires pre-formed attractors. However, that model opens up to other sub-threshold memory mechanisms that can maintain STM when LTMs are not present, yet.

So maybe if an RNN has memory that scales up with the size, it is a better model of activated LTM rather than of STM. No?

Short-Term Memory and Long-Term Memory are Still Different A commonly expressed view is that short-term memory (STM) is nothing more than activated long-term memory. If true, this would overturn a central tenet of cognitive psychology—the idea that there are ...

4-7 *new* items! If you learn to use a retrieval structure, you go pretty big - as all those crazy memorists do!

online WM of novel items require variable binding, and I doubt you can get it in RNNs.

IMHO. Because it does not have "memory slots" ready for it, if it has memory slots, it lacks the machinery to convert them back into sensory representations. But you're the RNN expert, if you say it, I believe you ;)

Can it distinguish a shape it saw once from one it never saw? And despite visual distractors?

Maybe we do have five stable attractors in pfc and use them to re-cue sensory perceptions. But we need to be clear about active/silent interactions to move forward in this direction.

True. However, the attractor `iff` pers. activity is the case only if we consider the firing rate as the only variable at play in the brain. Any cognitive theory of WM requires the allocation of new items on the fly. Can we build attractors through single-shot learning? Or we repurpose the same?

True! However, we have learned about long-term memory formation and maintenance from snails. Divergent evolutionary paths can yet implement similar computational mechanisms. IMHO, recurrent activity is not as prominent in monkey's PFC as in fruitfly MB, but the comparison holds.

If you're still updating the starter pack, add me in ;)

At #BernsteinConference heated debate on WM mechanisms. I love that this is still far to be settled!

trained RNNs from A.Compte aligns with fruitfly direction WM data from K.Nagel: it is persistent.

Large scale recording in macaque V1 in T.Moore Lab: it is not.

#neuroskyence what's your take?

And concluding with a beautiful thermodynamics of learning:

The correct learning rate depends on the noise of the training set (sigma eta)!

And reminding the great neuroscientist **and middle east pacifist** Daniel Amit!

So cool to walk from Ising models to recurrent network dynamics at the Braitenberg prize ceremony of Sara Solla! At #bernstein conference #compneurosky

The library strikes a balance between creating new models and composing them in fairly complex networks.

If you would like some specific feat and cannot achieve it, just contact me and we'll find a way together!

Hey #neuroskyence and #compneurosky

I recently released this #Julia library for simulating Spiking
Neural Networks!

bit.ly/4mAbRly

As with everything in Julia, it is fast, elegant, and compact!
Check out the documentation and the tutorials to get an idea!

Where do they get all this money to infest our market anyway???

And yess! The students loved it :)

Hey #neuroskyence #compneurosky

I made this interactive tool for showing the phase planes of 2D neuron models to studs!

Have fun :)

Thank you! I wanted to feel better this mornin 🤣

Spatially distributed and regionally unbound cellular resolution brain-wide processing loops in mice Until recently, it has been possible to examine activity in the brain globally through regional averaging or locally at cellular resolution. These studies characterized regions as functionally homogen...

Progesterone in the brain - Neurofrontiers Progesterone is a sex hormone with broad effects beyond the reproductive system, in particular in the brain.

Progesterone is another sex hormone best known for its effects on the female reproductive system. Similar to estrogens, however, it’s becoming increasingly clearer that progesterone impacts many more systems in the body, both in females and in males.

Will this be online?

There are examples of different IPSP dependently on the location of the afferent on the postsynaptic neuron. That would do?

I don't understand, whats the problem if people use chatgpt to write part of their text?

Like, the write the prompt with the info in bullet points, and ask for a text. Is this any type of scientific fraud?
