🧠 Resting-state fMRI is often treated as the gold standard for studying the brain’s intrinsic organization.

But is it actually the best way to estimate functional architecture?

We tested this directly.

What if you could automatically transcribe children's speech sounds from their first babbles to full sentences?

Screening for speech delays. Comparing how kids learn to talk across languages. Following how sounds evolve month by month.

We're building toward this with BabAR🧵 (sound on 🔊)

Compact deep neural network models of the visual cortex Nature - Parsimonious deep neural network models can be used for prediction of visual neuron responses.

DNN models of the brain are getting bigger. Are we replacing one complicated system in vivo with another in silico?

In new work, we seek the *smallest* DNN models of visual cortex, balancing prediction with parsimony.

It turns out these compact models are surprisingly small!

If anyone wants to pick up the method, happy to share & explain!

Excited to share that our MEG project is now out in Current Biology! We show how visual content codes relate to motor oscillations in telling time.

Medial Pulvinar Nucleus as a Causal Hub for Heteromodal Naming Our ability to retrieve the names of objects in our environment is a fundamental aspect of everyday life. This process requires a complex, dynamic network of cortical and subcortical interactions. Whi...

Out now in #JNeurosci! We used direct recordings and stimulation in human pulvinar to probe its causal role during naming from pictures, and spoken and written descriptions. We found naming-selective responses and stim-induced pure anomia.

Episodic memory encoding fluctuates at a theta rhythm of 3–10 Hz Nature Human Behaviour - Biba et al. show that episodic memory encoding fluctuates at a theta rhythm of 3–10 Hz.

I am excited to share my first paper, showing that episodic memory formation is theta rhythmic, is now published in Nature Human Behavior! Check it out here: rdcu.be/e6pzS. Thanks to my PI, Katherine Duncan, and to my collaborators for their support on this journey! Stay tuned for iEEG follow up 🧠

We think of white matter as the highways of the brain. But when we followed development along those highways, we were surprised. The journey is more complex than we thought. My final PhD paper, “Two Axes of White Matter Development”, is now out in @natcomms.nature.com! 🛣️🧠✨

(Perceptual) space and time are warped by the gravity of objects and events in their vicinity. There's been a flurry of work recently documenting examples of this gravity, all resulting in some really neat illusions.

RSA folks: How would you estimate the "dimensionality" of time-resolved neural (e.g., iEEG or M/EEG) RDMs?

I have been running MDS at each time point and using the scree "elbow", but I feel there should be a more principled way to estimate the RDM dimensionality?
