    Our first paper on sub-cellular cortical function in realistic-ish navigation behavior: We simultaneously imaged dendrites and their somas in retrosplenial cortex while mice walked around and rotated freely despite 'head fixation' during 2-photon imaging.

    To celebrate 1k followers, here's the first post in a series where I review various glues. We start with the 5/5 star rated top entry: epoxy.

    Taking apart the old rig to build the new rig. Always feels odd.

    First round of next generation headstage mass production is complete! 160 components smashed onto a 19mm diameter, 8-layer PCB requires some serious QC. MicroCT scans of each board ensure our assembly pipeline is on point. Look close and see if you can find the inductor 😀

    Local dendritic calcium events exhibited spatial and/or head-direction tuning that was not identical to their parent soma. This indicates that dendrites in RSC fulfill the requirements for performing subcellular computations such as local coincidence detection during behavior.

    Apical dendrites could exhibit calcium transients when their somas did not (and sometimes times vice-versa). This could be caused by a variety of mechanisms. Our 1st question was if these events represent unique information or if they mirror their parent soma.

    Dendrites and their somas were simultaneously imaged with a fast tunable lens. Images were corrected to remove rotation and distortion. We then analyzed head-direction and location tuning of dendrites and their respective somas.

    Mice acclimatize and explore the arena within seconds of first exposure to the system, in contrast to conventional head-fixation which requires more habituation. This should make it possible to apply classical head-fixed methods to a variety of naturalistic mouse behaviors.

    The system measures the torque that the mouse applies to the headpost, and rotates it to keep that torque close to zero. Because we do this very quickly, the headpost functions as a friction-free, weightless bearing. The floor is a floating 2D arena.

    excited to share our paper w/ 1st author Nina Fultz: Sleep is important for brain health, but why? We discovered CSF waves during sleep, locked to slow neural rhythms. Comp. model suggests neural activity can lead to CSF flow through hemodynamic coupling.

    Why consulting in neuroscience makes sense: If real life was like academia, you'd not bring your car to mechanics but miss weeks of work because it's cheaper to fix by yourself. Learning valve timing charts would be seen as part of your training. New post:

    If you’re doing exps. with freely behaving mice you deal with twisted tethers. We just solved this problem: our headstages tells the commutator which way the mice turn (gyro+compass), and it turns via a motor. Come see it at booth 1766 at .

    This standard (open neuro interface - oni) can do to neuroscience tools what USB did for printers/mice/keyboards/webcams etc. Its hard to overstate what a feat by and this is. Come see it & them at booth 1766 at .

    New preprint from the documents the initial findings from ~70 TB of publicly available Neuropixels recordings across the mouse visual system. All the physiology data was acquired with the Open Ephys GUI.

    Want to see the new drive implants in person and check out how to build them? Drop by our booth (1766) at . All the drive stuff we show there is now available online and we're even working out ways to provide training on how to use drives.
