Our paper is out in Nature, congrats to Qiyu, An et al! By stimulating ~20 motor cortex neurons carefully selected based on their activity, we could induce learned population activity and, sometimes, the movement itself, depending on the brain's state. nature.com/articles/s41586-0…

Targeted stimulation of motor cortex ensembles drives learned movements

Nature - Optogenetic stimulation of motor-cortex neuron ensembles shows that precisely timed activity in the primary motor cortex can generate learned neural patterns and movements, demonstrating...

1. CRISPR came from basic research on bacteria. 2. Optogenetics started with a discovery in algae. 3. The GFP protein comes from jellyfish. The biggest breakthroughs all trace to scientists follow their curiosity. This is one huge reason why we must keep funding basic research!

Our new paper is out in Nature, congrats to Sonja et al.! An excellent collab with Irina Dudanova's group. We promoted neuroplasticity to improve behavior in a mouse model of a neurodegenerative disease. nature.com/articles/s41586-0…

Restoring cortical disinhibition improves Huntington’s disease phenotypes

Nature - In a mouse model of Huntington’s disease, targeted modulation of neuronal activity restores network function and improves motor deficits.

Our new paper is out in Current Biology! We learn many things in parallel, and brain circuits are constantly rewiring across brain areas. It is notoriously difficult to understand which rewiring events are responsible for which type of learning. sciencedirect.com/science/ar…

Our new paper is out in Neuron! cell.com/neuron/fulltext/S08… How does the brain decide how much of the past to use when making decisions? In rapidly changing environments, recent experiences matter more; in stable environments, longer histories are useful.

Our new work is out in Science Advances. We show that neural activity in the striatum reflects not just cortical inputs, but also often-underappreciated thalamic inputs. science.org/doi/10.1126/scia…

Complementary cortical and thalamic contributions to cell type–specific striatal activity dynamics...

Cell type–specific striatal activity during movement is shaped by cortical and thalamic inputs with complementary roles.

🧵1/ Excited to share our new paper: "Brain Region-Specific Epigenomic Reorganization and Altered Cell States in Alzheimer’s Disease" We built a single-cell multi-omic atlas (DNA methylation + 3D genome) from AD and control brains. Paper: biorxiv.org/content/10.1101/…

Brain Region-Specific Epigenomic Reorganization and Altered Cell States in Alzheimer’s Disease

Alzheimer’s disease (AD) is the most common neurodegenerative disorder, yet the molecular mechanisms underlying its region- and cell-type-specific pathogenesis remain poorly defined. Here, we...

Thrilled to share my postdoc work from @takaki_komiyama lab, showing how motor learning reshapes thalamic influence on motor cortex to enable learned movements. Hats off to our collaborators and co-authors for their incredible contributions! nature.com/articles/s41586-0…

Motor learning refines thalamic influence on motor cortex

Nature - Imaging and optogenetics in mice provide insight into the interplay between the primary motor cortex and the motor thalamus during learning, showing that thalamic inputs have a key role in...

Our new paper is out in Science. What is the synaptic plasticity rule in the brain, we asked. It turns out there are multiple, even within individual neurons. Congrats Jake! science.org/doi/10.1126/scie…

Distinct synaptic plasticity rules operate across dendritic compartments in vivo during learning

Synaptic plasticity underlies learning by modifying specific synaptic inputs to reshape neural activity and behavior. However, the rules governing which synapses will undergo different forms of...

663 days since the senseless tragedy that took An, we present a manuscript that reports some of the discoveries that she left us. biorxiv.org/content/10.1101/…

Targeted stimulation of motor cortex neural ensembles drives learned movements

During the execution of learned motor skills, the neural population in the layer 2/3 (L2/3) of the primary motor cortex (M1) expresses a reproducible spatiotemporal activity pattern. It is debated...

Excited to share our latest research published in @Nature! We explored how working memory representations evolve and stabilize with practice, using simultaneous volumetric imaging of more than 73,000 neurons. Big thanks to my amazing team and collaborators! Special appreciation to @pgolshani and Alipasha Vaziri for their invaluable contributions. Let’s dive into the highlights! #Neuroscience #Research #Memory #Science #NeuralDynamics 🌟🔬🧠
