Many people have no mental imagery. What’s going on in their brains? People with aphantasia are offering a window into consciousness.

A feature in Nature examines the research about aphantasia, which is the experience of people with no mental imagery, and how it could offer a window into consciousness. #Neuroskyence 🧪

Neuronal networks in the dorsal hippocampus causally regulate rescue behavior in mice dos Santos Correa et al. show that exposure to a stressful context promotes the acquisition of rescue behavior in mice and that the dorsal hippocampus is required for this learning. Calcium imaging re...

Thrilled to share that our first study on the hippocampus’ role in helping behavior in mice is now published in @cp-cellreports.bsky.social! This work was driven by an amazing team in my lab, and marks an important milestone for more exciting studies to come!

Insular cortex predictions regulate glucose homeostasis Brain-body interactions are essential for physical and emotional homeostasis. The brain uses information from the external world to predict upcoming bodily changes. This process involves interoceptive...

lab preprint! Interopceptive predictions are central to many brain-body interactions theories, but it's unclear if/how they affect bodily physiology. We (fearless Einav Litvak et al) show that insular cortex predictions are essential for glucose homeostasis-THREAD.. www.biorxiv.org/content/10.6...

Integration of hunger and hormonal state gates infant-directed aggression - Nature Combined behavioural, circuit-level and cellular approaches are used to demonstrate how hypothalamic neurons integrate hunger and oestrous state to drive a switch in how female mice interact with pups...

Out today in Nature: We uncover a neural mechanism for the integration of two internal states - hunger and estrous state - and how this integration shapes pup-directed behaviors in mice.

A hypothalamic circuit that modulates feeding and parenting behaviours - Nature Single-cell transcriptomic analysis of mouse hypothalamus and behavioural experiments show that specific hypothalamic networks regulate conflicting feeding versus parenting behaviours of female mice.

How do animals decide if they should forage for food or stay home to take care of newborn offspring? Whose needs come first? For my PhD work now out in Nature, we examined how hunger and parenting neurons interact and are reshaped postpartum in mice 🧵⬇️ www.nature.com/articles/s41...

Stereo olfaction underlies stable coding of head direction in blind mice - Nature Communications Stereo olfaction involves comparing odor differences between the two nostrils. Here, using neuronal recordings and a behavioral test, the authors demonstrate that blind mice use stereo olfaction to fo...

Blind mice use stereo olfaction, comparing smells between nostrils, to maintain a stable sense of direction. Blocking this ability disrupts their internal compass.
