Interesting that this study on infant brain development is not done with fMRI but with fNIRS (functional near-infrared spectroscopy [1]). And concerning to read about the complete reliance on software provided opaquely by a company for the analysis: "As all fNIRS data preprocessing was carried out on MATLAB-based toolboxes, no custom scripts are available."
[1] fNIRS measures more or less the same as fMRI: blood flow. "Using fNIRS, brain activity is measured by using near-infrared light to estimate cortical hemodynamic activity which occur in response to neural activity." https://en.wikipedia.org/wiki/Functional_near-infrared_spectroscopy

See all published Reviewed Preprints https://elifesciences.org/reviewed-preprints
Within themes, #eLife makes no distinction between old-style articles (where editors decided whether a manuscript is accepted) and reviewed preprints (where authors decide instead). Keep in mind both have the reviews attached, including as of recently a brief assessment paragraph summarizing, with a controlled vocabulary, the significance of findings and, more importantly, the strength of evidence.

Glia Accumulate Evidence that Actions Are Futile and Suppress Unsuccessful Behavior
Whole-brain imaging in virtual-reality-immersed zebrafish reveals that failed swim attempts are detected by noradrenergic neurons, which drive glial cells that accumulate calcium until they trigger the suppression of further futile attempts.Cell
I’m currently a postdoc in Marlene Behrmann’s lab at Carnegie Mellon. I’m broadly interested in understanding the #psychology and #neuroscience underlying the #development of cognitive abilities such as categorization.
Recently I’ve been exploring the broader biological network that may support may object categorization (e.g., https://doi.org/10.1016/j.tics.2022.09.019) and the #computational processes that may support few-shot categorization in infancy (e.g., https://doi.org/10.7554/eLife.74943)
Perception of an object’s global shape is best described by a model of skeletal structure in human infants
Six- to twelve-month old infants, who have little linguistic or object experience, classify objects by relying on a invariant representation of global shape known as the shape skeleton.Vladislav Ayzenberg (eLife Sciences Publications, Ltd)

After countless conversations that I read too little, I decided to read 1 paper on every workday of 2022 and point to them on SocMedia.
Papers are in the general area of #cognitive + #sensorimotor #neuroscience, including meta-stuff such as #OpenScience.
List of papers so far with links to tweets - toots from now on…

I'm at #133 – doesn’t mean I had lots of vacation but rather that sticking to the plan hasn't been easy ;)
Hi all,
I am a Group Leader at HHMI Janelia Research Campus, working on the systems #neuroscience of flexible behavior and #learning, #brain-body communication, #microscopy, #computation, #astrocytes, and large #networks.
We enjoy collaborating, including with computational neuroscientists who want to take a look at whole-brain neuron + behavior data! Get in touch 😀
