Now in Science: How does the brain’s navigation system allocate its limited representational resources during behavior? We found that grid cells sweep toward locations of interest, providing a potential mechanism for allocating spatial attention in the cognitive map.🧵 science.org/doi/10.1126/...

Ants normally use about 24% of their energy for brain functions, but when food-deprived, this percentage nearly doubles to 45%. Preferential energy allocation to the brain has previously been found in humans and other mammals. In PNAS: https://ow.ly/kVkU50ZwbrB
New Study! @cbehav.bsky.social @mpi-animalbehav.bsky.social Often foraging models assume that the forager knows the environment and proceed to predict decision strategies but how does the foraging learn the structure of the environment ? A new preprint delves into this question
Finally out in @natneuro.nature.com! A forgotten memory isn't always gone. We show that forgotten memories persist as silent memory traces, can be recovered by reminders, and can even be reconstructed into false memories. Excited to finally share this work! www.nature.com/articles/s41...

We are excited to share our collaboration with @pheereynolds.bsky.social, Robert Hindges & team on retinal plasticity, now out in Neuron! This work shows how visual experience during early development changes the anatomical and functional properties of amacrine cells and ultimately behavior!
Early visual experience elicits cellular and functional plasticity in the retina and alters behavior
The understanding of experience-dependent plasticity in the vertebrate retina is largely incomplete. Reynolds et al. discovered that raising animals in differently patterned visual environments change...

Preprint Alert! Walking mostly feels natural and easy to us - but the neuronal control of walking is actually incredibly complex. We leveraged the fruit fly as a genetically tractable animal model with a compact nervous system to ask how the brain controls walking direction: tinyurl.com/flywalk. 🧵..

Macrophages in the liver as sensors for the earth magnetic field with signals sent to the brain via the vagal nerve 😮 I'm struggling to understand how this would actually work as a compass signal but it would be very cool. Also, this pigeon portrait makes for an adorable cover! 🕊️
Researchers have identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. https://scim.ag/4nTQ3nq

This is definitely something that should be discussed before implementation. Read and provide feedback. What we need is more funding, not more restrictions. A particularly bad move for Starting, and specially, Consolidator stage.
What should Europe do when demand for #ERC funding keeps rising? Restrict access or invest in excellence? Please read our open letter calling for reconsideration of the ERC 2027 resubmission restrictions & for constructive alternatives that preserve openness Consider to share & sign - see below 🧪
