Tensor Component Analysis (TCA) for Neural Plasticity in Maternal Learning

  • Developed and implemented statistical modeling method TCA to decompose high-dimensional neuron-firing data from the paraventricular nucleus (PVN) of mice, identifying structured neural patterns underlying maternal behavior learning
  • Discovered that active maternal learning strengthens neural synchrony and precise temporal firing, demonstrating that oxytocin-related PVN circuits drive adaptive plasticity in social learning
