Ever wonder how habituation works? Here's our attempt to understand:

This is the thesis of two wonderful students: @anjiecao.bsky.social @galraz.bsky.social, w/ @rebeccasaxe.bsky.social

Amazing talk from @sjblakemore.bsky.social at #flux2025 - childhood and the age of legal responsibility; voting age; graduated driving licenses.

Excited for our new OPM-MEG system!

Finally got around to this interesting exchange. Much to like! However, in my view neonate cortex is building a foundation model while sub-cortical sensorimotor routes support newborn behaviours and, importantly, bias the inputs to the foundation model (e.g. orienting toward faces).

This is a great opportunity for rising stars and established research leaders particularly when combined with an ERC frontier research grant (€4-4.5 million including relocation-to-Europe supplement).

Very pleased that my commentary on Jonathan Birch's fantastic "The Edge of Sentience" has finally appeared. @birchlse.bsky.social and I agree on many things, but there was enough distance between our views to make this a productive exchange.

Thank you very much for the discussion, Martin, @marielgoddu.bsky.social and Ruthe! Look forward to discussing more. Will any of you make it to CCN in Amsterdam?

Interesting! Random exploration is consistent - the important thing is that the infant doesn't start to optimize decisions that corrupt learning by forcing early cheap solutions building on sub-optimal representations.

Eye movements are exploration too as @rebeccasaxe.bsky.social reminds me

I love the idea of explore-to-exploit transition in childhood! But, in the helpless period (first 6-8 months?) there's no reaching, crawling or walking, and humans get much less exploration done than a chicken or a lamb. Pre-exploration infantile chillaxing- that's what we're trying to explain.

I'm glad you like the fundamental point. The novel contribution is to suggest that the requirement for lots of self-supervised learning upfront could drive a long helpless period in human infants. Otherwise, helplessness is dangerous and such a lot of work for the caregivers!

Emily, I haven't read your paper yet and it looks interesting! But I'm curious why you didn't cite @cabrallaura.bsky.social's work (with me) examining the connectivity of ventral visual category regions in neonates pubmed.ncbi.nlm.nih.gov/36521345/

Why do we not remember being a baby? One idea is that the hippocampus, which is essential for episodic memory in adults, is too immature to form individual memories in infancy. We tested this using awake infant fMRI, new in @science.org #ScienceResearch www.science.org/doi/10.1126/...

Cortical maturation unfolds hierarchically, endowing the PFC with extended plasticity. But do timeframes of plasticity vary across PFC layers?

With 7T quantitative myelin imaging, EEG, and cognitive data, we uncover heterochronous laminar maturation in the PFC 1/n. www.biorxiv.org/content/10.1...

Congratulations!
