This study reveals the complex and heterogeneous circuit changes underlying stroke recovery. It also highlights the therapeutic potential of interneuron circuits as a target for recovery interventions.

Rehabilitative training recovers PV synapses, functional connectivity, and gamma power.

Using chemogenetics, we found that activating PV interneurons is essential for recovery. Remarkably, pharmacological PV activation mimics rehab benefits.

We identified neurons projecting to the stroke site (Stroke-projecting neurons) lose key synaptic inputs, including those from PV interneurons.

This loss disrupts functional connectivity, leading to decreased gamma power and impaired motor function.

Stroke recovery depends on plasticity.
Rehabilitation harnesses experience-dependent plasticity, but how specific neuronal circuits drive recovery has remained unclear—until now.

We identified key inhibitory circuits shaping rehabilitation-induced recovery.

🔥 Inflammation and neuron protection

In aging brains, genes associated with inflammation became more active, while those related to neuronal structure and function decreased.
