  1. La oxitocina tiene efectos distintos dependiendo de que neuronas la liberen (NPV posterior, NPV anterior, extensión amigdalina, etc) y en que patrón lo hagan (el patrón electrofisiológico de las neuronas es muy distinto!!)

  2. 🧠 New preprint by Kim et al. (2025) from David Anderson’s lab: A line #attractor maintains aggressiveness during feeding in “hangry” mice 🍔🐁. Using in vivo #CalciumImaging and #rSLDS modeling, they show how moderate fasting stabilizes an aggression-related attractor in #VMHvl, while prolonged fasting collapses it, linking hunger, motivation, and aggression through #PopulationDynamics:

  3. Subset of neurons in #hypothalamus increases appetite & decreases #thermogenesis. @JongSohn &co show that ion channel GIRK2 functions in hypothalamic NPY/AgRP neurons to increase energy expenditure in mice and may control body weight @kaistpr #PLOSBiology plos.io/3qGa8Ev
