#Researchers propose that a taste for #fermented morsels may have triggered a surprising jump in the growth rate of our ancestors' #brains.
In fact, a shift from a #RawDiet to one that included #food items already partially broken down by #microbes may have been a crucial event in our brain's #evolution, according to a perspective #study by evolutionary #neuroscientist Katherine Bryant of Aix-Marseille University in France and two US colleagues.

Babies Learn Language Best Through Sing-Song Speech, Not Phonetics

Parents should speak to their babies using sing-song speech, like nursery rhymes, as soon as possible, say researchers. That’s because babies learn languages from rhythmic information, not phonetic information, in their first months.

New neuroscience research upends traditional theories of early language learning in babies
The findings challenge traditional theories of language acquisition that emphasize the rapid learning of phonetic elements. Instead, the study suggests that the individual sounds of speech are not processed reliably until around seven months, and the addition of these sounds into language is a gradual process.

This Scientific American issue from 1979 reads like a who's who of early neuroscience research:
Cowan, Crick, Kandel, Hubel, Wiesel, Stevens ...
https://www.scientificamerican.com/issue/sa/1979/09-01/
In particular, Ordaz et al. 2017 https://doi.org/10.4103%2F1673-5374.213532 credit Francis Crick in this issue as having formulated the need for optical methods with cellular resolution to control the activity of neurons - a precursor to the development of optogenetics.
Crick's idea didn't come out of the blue: by then, bacteriorhodopsins (light-gated ion channels for protons) had been known and published for almost a decade (Oesterhelt and Stoeckenius, 1971 https://www.nature.com/articles/newbio233149a0 ), and halorhodopsin (light-gated chloride channel) had been reported 2 years earlier (Matsuno-Yagi and Mukohata 1977 https://www.sciencedirect.com/science/article/abs/pii/0006291X77912451 ).
(Channelrhodopsin, a light-gated cation channel that can depolarise and therefore activate neurons, wasn't reported until 2002, by Nagel et al. 2002 https://www.science.org/doi/full/10.1126/science.1072068 ).
Young individuals with autism not only experience heightened daily stress but also tend to employ less effective emotional regulation strategies compared to their non-autistic peers.

“The brain doesn’t look like it’s in a state of memory; it looks like it is a state of present experience.”
Indeed, the authors conclude in the paper, “traumatic memories are not experienced as memories as such,” but as “fragments of prior events, subjugating the present moment.”

#SFN23 poll: did you test positive to #Covid19 either during or after the conference?
(For context: SFN is a #Neuroscience conference with more than 20000 people and very few were masked)
And to note that Geerlig's point (1) above on the mismatch between white matter tracts and functional networks should be pondered by those using tractography (another coarse spatial resolution technique) to make models of brain function. There are many such papers.
In 2015, I attended the first talk ever featuring fMRI where I found the application and results convincing. The talk was by Linda Geerligs and she described her, at the time, recent paper:
"A brain-wide study of age-related changes in functional connectivity" Geerligs et al. 2015
Cerebral cortex 25 (7):1987-99 https://academic.oup.com/cercor/article/25/7/1987/462366
The work focuses on longitudinal studies on humans, studying the same person over the years with fMRI. In her talk, she pointed out that:
(1) functional networks are not correlated with white matter tracts;
(2) there is a strong decline in functional network modularity with age;
(3) with age; intramodule connectivity decreases and intermodule connectivity increases;
(4) old adults that maintain the highly segregated functional network retain their mental abilities.
Overall I found the technique well suited to the question. In the first place because the study is longitudinal, comparing subjects to themselves over time. In the second place, because it did not attempt to make statements about specific areas of the brain, but rather, on how the relationships between areas, as far as they could be observed, changed over time within an individual.
An interesting study from which what we learn is matched to the strengths and limitations of the technique, and which does not attempt to make sweeping statements about the function of specific areas of the brain. At least that's what Geerligs did in her beautiful talk.
There may be caveats and limitations to the study, but as a non-fMRI specialist, I am unable to see them. Reads humble and as precise as it can be, not more and not less.
One study that comes to mind is:
"Motor Control by Sensory Cortex" by Matyas et al. 2010 (Carl Petersen's lab) https://www.science.org/doi/full/10.1126/science.1195797
... where they report "an additional and equally direct pathway for cortical motor control driven by the primary somatosensory cortex" in mice. This surprising result, breaking with Penfield's century-old division of labour between the motor cortex and the somatosensory cortex, is supported by voltage-sensitive dye (VSD) imaging of the whole mouse brain, showing widespread activity propagation with latencies of tens of milliseconds across most of the whole brain.
Suppose we were to attempt a similar measurement in humans with fMRI. What would we see with the very low pass filter in the temporal and spatial dimensions that we get from fMRI?
Perhaps this is indeed the wrong question, and in humans we ought to be asking different questions. But what questions? Matyas et al. highlights:
(1) how fast and wide signals spread across the whole mammalian brain;
(2) the inaccuracy of old neuroanatomical divisions of the brain;
(3) the fact that a much larger fraction of the brain is involved in any one behaviour than previously thought, larger than would have been ideal to make sense of the brain as a modular system when its activity is monitored with the low pass filter that is fMRI.
My question is: what kind of studies are sensible given fMRI's strengths and limitations? I have one example in the next post.

Periodic reminder of what fMRI's BOLD signal is measuring, and its temporal dynamics:
"blood oxygenation level–dependent (BOLD) contrast. [...] increased signal in a voxel measured with an EPI [echo planar imaging] sequence indicates recent neuronal activity because of the relative increase in local blood oxygenation that accompanies such activity. The temporal profile of this BOLD response, known as the hemodynamic response function, looks like a bell curve with a long tail, peaking around 4 to 5 seconds after local neural activity and returning to baseline after 12 to 15 seconds."
From "Principles of Neural Science", Kandel et al. 6th edition, page 115.
No matter how fast the EPI imaging is (~100 ms), the BOLD dynamics makes GCaMP look lighting fast. Temporally deconvolving BOLD is possible, to a point, but remember its spatial resolution is measured in millimetres, whereas neuronal somas measure ~0.025 millimetres.

These results were reproduced 35 years later by Witvliet et al. 2021:
"The wiring diagram is not stereotyped"
"Each worm has connections that are not found in other individuals.
About 43% of all cell–cell connections—accounting for 16% of all chemical synapses—are not conserved between isogenic individuals. By contrast, physical contacts between neurites at birth are maintained across developmental stages. Wiring variability contrasts with the assumption that the C. elegans connectome is hardwired."

So long and thanks for all the science DC! It was a great (and very busy) #SfN23 #SfN2023 #neuroscience
Hello science friends! Can anyone point me towards some resources that I could use learn how to do a de novo genome assembly from long reads (@nanopore)? Mammalian species, no reference genome exists. An equally exciting and daunting task.... Please share #neuroscience #genomics
Looking for a great poster to come see? 👀Come see ours now (Tues afternoon) at UU13 #SfN23 #SfN2023 #neuroscience @katiconen
"Zoom Fatigue": Exhaustion caused by video conferencing proven on a neurophysiological level for the first time - Using EEG and ECG data, researchers were able to prove that video conferences and online education formats lead to greater fatigue than face-to-face alternatives.
