    Cues that predict reward activate dopamine neurons but the function of this response remained unclear. This study demonstrates that inhibiting dopamine cue responses impairs second-order conditioning as predicted from TD learning theory. Elegant study!

    Thrilled to share our paper out today in Nature Neuroscience. We developed a novel chemogenetic strategy (ciPSI) to block new protein synthesis in specific cell types using an engineered drug-inducible version of eIF2α kinase PKR. 1/n

    Lots of exciting research to be done in 2020! I present to you multi-engram labelling in coronal sections of the mouse neocortex and hippocampus. Stay tuned for updates.

    Janelia scientists Philipp Keller and Kate McDole have been awarded 5th place in the Nikon Small World in Motion competition. Their winning entry shows the inside of a developing mouse embryo as the neural plate (which later gives rise to the brain and spinal cord) elongates.

    We can detect rearing in mice (also head direction) by analyzing the magnitude and direction of vectors made from body part identifiers tracked using in a social task. Blue dots indicate rearing behavior

    Wow: Facebook's Head of AI, , says the Field Will Soon ‘Hit the Wall’. There must be some pretty intense internal debates over there. ⁦

    Must read- this 'long-term' study of spike timing dependent plasticity (STDP) suggests LTD is transitory or an artifact of recording (at least in the Schaffer collateral circuit)... Very interesting!

    Recordings from 30,000 neurons in 42 brain regions of mice performing a visual discrimination task are reported in Nature. The findings reveal the spatial distribution of neuronal activity underlying vision, choice, action and behavioural engagement.

    Okay this is super weird: a neural network trained on non-face objects also has neurons with selective for human faces??
