Should you stick to your goal, try something else, or give up? Your median raphe nucleus in the brainstem knows and will decide for you 😉. First foray of my lab into foraging, behavioural strategies and exploration. Amazing work from the one and only Mehran Ahmadlou: www.nature.com/articles/s41...

A subcortical switchboard for perseverative, exploratory and disengaged states - Nature

Behavioural experiments in mice demonstrate that GABAergic (γ-aminobutyric acid-expressing), glutamatergic and serotonergic neurons in the median raphe nucleus have distinct and complementary function...

So excited to see this out, heroic effort by the brilliant Sara Mederos, uncovering the detailed brain mechanisms of how animals learn to overcome their instinctive fear responses, from neural circuits & cell types down to synaptic plasticity mechanism! www.science.org/doi/10.1126/...

Overwriting an instinct: Visual cortex instructs learning to suppress fear responses

Fast instinctive responses to environmental stimuli can be crucial for survival but are not always optimal. Animals can adapt their behavior and suppress instinctive reactions, but the neural pathways...

Cool study led by Mitra Javadzadeh and Marine Schimel on the function of inter-areal communication in the neocortex, using data from my lab and biologically-constrained latent circuit modelling with Guillaume Hennequin and Yasha Ahmadian #neurosky #neuroskyence www.biorxiv.org/content/10.1...

Dynamic consensus-building between neocortical areas via long-range connections

The neocortex is organized into functionally specialized areas. While the functions and underlying neural circuitry of individual neocortical areas are well studied, it is unclear how these regions op...
