@mishaahrens Tagging this #PaperThread on #neuroscience: "circuits for path integration and their effect on #behavior" in #zebrafish by @mishaahrens 's lab so that we can find it in the future :)

And thanks to the broader neuroscience and zebrafish communities for their super inspiring work that this study built upon!

Do mammals have a SLO-MO that integrates optic flow or local movements? We hope mammalian researchers will test it – we think it might be in the vicinity of the nucleus prepositus hypoglossi

16/n

To summarize, one way the fish brain tracks position changes is by integrating optic flow in SLO-MO, and passing it on to the inferior olive, then cerebellum, and finally premotor circuits to drive compensatory swimming

15/n

Even further down the network, the cerebellum also contained activity that correlated with positional shifts of the fish
