maybe it's just me but I haven't been able to build any statistical forecasting models from your statistical model of language

I'm just one person, and my programming needs are somewhat unusual (building various kinds of statistical forecasting models). But I'm just not seeing the consistent productivity gains from LLMs that I would have expected if you'd asked me 6 months ago.

In a new exciting collaboration with @marlenfroehlich.bsky.social and @profgerhard.bsky.social we think about how studying ambiguity in human and great ape communication can advance our theories of language evolution. Paper out at doi.org/10.1016/j.ne...

Glad to hear you think so, I think I am officially now a non-expert but I was thinking something like that when I wrote "homolog"--thalamo-recipient pallium, i.e. Field L

A bit surprised it was so hard to find what *they* meant by it.

Not the main point of the paper but definitely makes me 🤔🤨

lol oh shit, I feel like I'm about to get a very long email

I copied their use of "homolog" without thinking about it

Looks like they use it to encompass not just L2 but also CM and a couple other areas?
We are now pretty sure these areas develop from DVR, so, not really ctx homolog, right?

Authors go on to show that

🐦 population response is the same outside critical interval
🐦 this effect does not depend on familiarity with song!
🐦 but it does depend on context, i.e. motif the syllable occurs in & whether song has species-typical syntax!

Under this model, neural response to song where a syllable is replaced with a gap + noise burst (GB) should look like response to the continuous syllable + noise (CB)

Single N recordings support this: firing rate during GB is most similar to CB vs control

Figure two showing single unit response to occluded song. Top panel A shows example raster plots of 3 single units responding to the five different conditions, including the gap noise burst condition GB that should induce the illusion of the syllable, the continuous burst condition CB that represents the illusory percept that the syllable is still present beneath the noise, and the three control conditions. Bottom left panel B shows population distribution of tone-noise similarity index values, see paper text for description. Panel C shows log X-Y plotting average firing rates on log scale during the critical interval during GB for all units, plotted against the other four conditions. Notably, the values appear by eye to be most similar during the GB and CB conditions.

Authors look at single neuron (Ns) activity in ZF homolog of mammalian auditory cortex

They test a model where internal dynamics bias a population of neural activity towards states driven by external input of song

#prattle 💬
#neuroskyence

2/5
Figure one from paper, panel A on left shows conceptual model where external input and internal network dynamics work together to drive a population of neurons through a sequence of states along a manifold, but when a syllable is occluded by noise the internal dynamics bias activity towards the state corresponding to the missing syllable. Internal dynamics is shown as a set of syllable labels A through E connected by arrows to form an oval, with external input coming in as an arrow in the lower left. There is an inner and outer set of arrows in the loop, with the inner set representing the internal dynamics, the outer set representing external input. Between syllables C and D, the outer arrow is replaced with a dashed line representing noise that would push the population activity off the manifold without the bias of the internal dynamics. Panel B is two spectrograms of zebra finch song, the one on the top shows the example gap plus noise burst stimulus, GB, and the bottom shows the continuous plus noise burst stimulus, CB. If internal dynamics fill in the missing syllable, then the GB stimulus should evoke the same neural response as CB despite not physically containing the target syllable.

15 years in the making, we confirmed that mitochondria - the powerhouse of the cell - have an unusual localization in patients who experience psychosis (including schizophrenia and bipolar disorders). You’ll never guess what kind of patient cells we used to make this discovery… 🧵
mitochondria from bipolar patients are closer to the nucleus in these images; control patients' are spread out further

important on LLMs for academics:

1️⃣ LLMs are usefully seen as lossy content-addressable systems

2️⃣ we can't automatically detect plagiarism

3️⃣ LLMs automate plagiarism & paper mills

4️⃣ we must protect literature from pollution

5️⃣ LLM use is a CoI

6️⃣ prompts do not cause output in authorial sense
5 Ghostwriter in the Machine
A unique selling point of these systems is conversing and writing in a human-like way. This is imminently understandable, although wrong-headed, when one realises these are systems that
essentially function as lossy2
content-addressable memory: when
input is given, the output generated by the model is text that
stochastically matches the input text. The reason text at the output looks novel is because by design the AI product performs
an automated version of what is known as mosaic or patchwork
plagiarism (Baždarić, 2013) — due to the nature of input masking and next token prediction, the output essentially uses similar words in similar orders to what it has been exposed to. This
makes the automated flagging of plagiarism unlikely, which is
also true when students or colleagues perform this type of copypaste and then thesaurus trick, and true when so-called AI plagiarism detectors falsely claim to detect AI-produced text (Edwards, 2023a). This aspect of LLM-based AI products can be
seen as an automation of plagiarism and especially of the research paper mill (Guest, 2025; Guest, Suarez, et al., 2025; van
Rooij, 2022): the “churn[ing] out [of] fake or poor-quality journal papers” (Sanderson, 2024; Committee on Publication Ethics, Either way, even if
the courts decide in the favour of companies, we should not allow
these companies with vested interests to write our papers (Fisher
et al., 2025), or to filter what we include in our papers. Because
it is not the case that we only operate based on legal precedents,
but also on our own ethical values and scientific integrity codes
(ALLEA, 2023; KNAW et al., 2018), and we have a direct duty to
protect, as with previous crises and in general, the literature from
pollution. In other words, the same issues as in previous sections
play out here, where essentially now every paper produced using
chatbot output must declare a conflict of interest, since the output text can be biased in subtle or direct ways by the company
who owns the bot (see Table 2).
Seen in the right light — AI products understood as contentaddressable systems — we see that framing the user, the academic
in this case, as the creator of the bot’s output is misplaced. The
input does not cause the output in an authorial sense, much like
input to a library search engine does not cause relevant articles
and books to be written (Guest, 2025). The respective authors
wrote those, not the search query!

"What they rely on is fear. So by coming out in an absurdist manner, it speaks to them, to some extent, that we’re actually not that afraid. When they try to describe this situation as 'war-torn,' it becomes much harder to take them seriously."
