Ethan Scott's Lab

Let's share @etlunsford.bsky.social's work : to survive, animals avoid drifting involuntarily in their environment. While humans rely on visual & vestibular cues, birds & fish need to sense complex flow changes of the external fluid (air/water) around them to select motor actions. How do they do?(1)

Thanks so much @trackingactions.bsky.social. This is not our wheelhouse, so expert advice is most helpful. We may be in touch for more detail if that's OK. Our goal is a useful little resource for zebrafish folks rather than a scholarly analysis, but we want to get the details right all the same.

ICYMI #zebrafish folks:

Fresh from ‪@lascholz.bsky.social‬ and Conrad Lee, we offer 4 models pre-trained with diverse fps and resolutions. Leandro’s done all of the clicking. Benefit from his suffering and plug straight into automated annotation of your videos!‬

Congrats to @stednitz.bsky.social and Andrew Lesak on their @currentbiology.bsky.social paper! They use HMM to identify two interaction states in #zebrafish: one visual for long-range interactions and one lateral line for quick, close interactions.

Coordinated social interaction states revealed by probabilistic modeling of zebrafish behavior Stednitz and Lesak et al. apply probabilistic modeling to classify larval zebrafish social behavior and characterize the sensory underpinnings of distinct interaction types.

Happy to share some new work on social interactions of zebrafish: using Hidden Markov models, @stednitz.bsky.social and Andrew Leszak show that there are three states of social approach behavior, and they differ in their sensory components.

Our paper on zebrafish phenotypes in Alzheimer’s risk genes finally is now in its final form at Elife!

Postdoctoral Fellow Job in Melbourne at Peter MacCallum Cancer Centre - SEEK The Hogan laboratory is offering work for a highly motivated and skilled postdoctoral fellow in the area of lymphatic development and regeneration.

We have a postdoc position available in the lab! Come and work on lymphatic vascular development and regeneration. We use zebrafish, mouse, cells, tumour models and love imaging, genetics and genomics🔬
Come join us in Melbourne!

www.seek.com.au/job/82157187...

The pleasure was mine, @lezanne.bsky.social. Hope we get to team up again next time!

I'm thrilled to announce that our paper describing Marigold, a free machine learning-based webapp for zebrafish behavioral analysis, is officially published! Marigold features a user friendly graphical user interface to enable training of a neural network for analyzing behavioral recordings.

The position would start in mid-late 2025. To apply, send a single PDF including 1) your cover letter detailing your past experience and specific interests in our lab's work, 2) CV, and 3) academic transcript. This can be emailed directly to Ethan: findanexpert.unimelb.edu.au/profile/9534...

Projects are available in calcium imaging, optogenetics, computational neuroscience, or behavioural analysis. Ideally, the new student will eventually span most or all of these disciplines. Work can involve fundamental sensory studies in wild-type animals or phenotyping of #autism model animals.

Zebrafish and non-zebrafish people are welcome. Internationals and those from underrepresented groups are encouraged to apply. Our lab is a mutually supportive team with positive vibes and an ethic of teamwork, looking for members with the same mindset. If that's you, read on👇

JOIN US! We're seeking a new PhD student in beautiful Melbourne🇦🇺.

Join our diverse, supportive team of optical physicists, neuroscientists, and mathematicians as we study how #zebrafish brains perceive the world.

Deadline: February 12th. Details👇. Please repost.

Sensation is dispensable for the maturation of the vestibulo-ocular reflex Vertebrates stabilize gaze using a neural circuit that transforms sensed instability into compensatory counterrotation of the eyes. Sensory feedback tunes this vestibulo-ocular reflex throughout life....

Big paper from @paigel.bsky.social in our lab:

Sensory feedback is always crucial for proper development, right? Wrong!

Crazier still, the motor system is the slowest part of a developing reflex circuit!

Surprises abound in this bluetorial c’mon along….

Pleased to make my first bsky post a joyful one. Congrats to Maya Wilde and Leandro Scholz on receiving their PhDs on Friday. So proud of you, and can't wait to see what your next chapters hold!

In an Aussie take on the Finnish top-hat-and-sword tradition, we gifted them Akubras and stock whips.
