Offline cerebello-cortico-striatal dynamics predict motor strategy exploration and retention in skill learning Learning a motor skill requires exploring multiple possible solutions to find and retain an optimal strategy. The exploration and consolidation of the motor strategy are usually considered to be segre...

Biological fidelity: The engine driving the neuromorphic renaissance | PNAS Biological fidelity: The engine driving the neuromorphic renaissance

Thrilled to see our PNAS paper featured in @giacomoi.bsky.social commentary. A fantastic recognition of how biologically grounded cortical microcircuits can accelerate the next generation of NeuroAI—and a meaningful step connecting it to neuroscience www.pnas.org/doi/10.1073/...

High-throughput synaptic connectivity mapping using in vivo two-photon holographic optogenetics and compressive sensing - Nature Neuroscience Using two-photon optogenetics, electrical recordings and sparse signal reconstruction, the authors demonstrate in vivo synaptic connectivity mapping in the mouse visual cortex.

CRISPR activation for SCN2A-related neurodevelopmental disorders Nature - Using SCN2A haploinsufficiency as a proof-of-concept, upregulation of the existing functional gene copy through CRISPR activation was able to rescue neurological-associated phenotypes in...

SCN2A loss is strongly linked to neurodevelopmental delays and, at times, seizure. In an amazing collaboration with @nadavahituv.bsky.social, led by Serena Tamura, Andrew Nelson, and Perry Spratt, we leveraged CRISPR activator approaches to rescue this loss.

Distinct dendritic integration strategies control dynamics of inhibition in the neocortex Morabito et al. observed that different neocortical interneuron (IN) populations display distinct dendritic properties by varying synaptic receptor composition and input location. These IN-specific de...

Happy to share that our work is out in Neuron today! We found that of PV and SST interneurons present distinct dendritic strategies, key to maximize synaptic efficacy and shape firing dynamics of these cells.

I am so excited about this combined analysis of the selective CRHR2 population within the lateral septum and how they control defensive behavior. Dionnet was truly a gifted graduate student. Keep your eyes on this one!

Human hippocampal CA3 uses specific functional connectivity rules for efficient associative memory Human hippocampal CA3 networks use sparse and broad synaptic connectivity, and their recurrent synapses employ reliability, precision, and long integration times to enhance memory capacity. Thus, the human hippocampus is distinct from both rodent counterparts and human neocortical circuits.

Innervation density governs crosstalk of GPCR-based norepinephrine and dopamine sensors GPCR-based fluorescent sensors are widely used to correlate neuromodulatory signaling with brain function. While experiments in transfected cells often reveal selectivity for individual neurotransmitt...

A must-read from the Kaeser lab

Presynaptic cAMP-PKA-mediated potentiation induces reconfiguration of synaptic vesicle pools and channel-vesicle coupling at hippocampal mossy fiber boutons Information storage in neuronal circuits is hypothesized to involve nanoscopic structural changes at synapses, but direct evidence for this is lacking. This study uses nanophysiology and functional el...
