Zenith 3rd Training Workshop - Basic Imaging


The third ZENITH bespoke workshop took place between 2-9 October 2022 at the Technical University of Munich (TUM). Through lectures the students learned the fundamentals of optics and microscopy, the use of different types of cameras and laser scanning systems. With the practicals, hands-on optics and microscope building exercises enabled students to develop an intuitive understanding of optical principles.

The one-week workshop was taught by the ZENITH faculty supported by teaching assistants from ZENITH labs. More info in our Training section and check some images in our Twitter and Instagram accounts!

Tanita's secondment at ICM

by &

Our student Tanita Tzotzolaki completed a 3.5-month secondment between May – August 2022 in Claire Wyart’s lab at ICM. The main goal was to perform a deep behavioural analysis of zebrafish genetic models of Parkinson’s disease. This involved characterising the behavioural defects of five genetic mutants of the disease using a high throughput set up to analyse free swimming and escape responses. While at ICM, Tanita had a chance to work closely with members of the Wyart lab, including Maha Dhanasekar and Feng Quan, whilst also spending more time with the Paris-based ZENITHers.

My time at ICM helped me evolve greatly on a professional, as well as a personal level. Learning to use a new set up and applying it to my project opened my eyes to the broad variety of techniques that can be applied to my project. I also found that my dedication to my work expanded greatly as I started collecting a large set of data to fit in and build the story of my PhD. Additionally, working with a group of people with different backgrounds really made me feel the interdisciplinary nature of the ZENITH consortium. I am really looking forward to returning to Claire’s lab to continue my research on the effects of Parkinson’s disease progression on zebrafish locomotion starting next year!




ZENITH was of course strongly represented at the FENS Forum 2022 in Paris, with several members present, fantastic talks and posters! Check out our Zenith Twitter account to see what we were up to at FENS! It was really an incredible and intense experience and a great exposure to the neuroscience community.

Outreach: Pint of Science!


In May 2022, I was part of the Beautiful Mind UCL Team for this year’s Pint of Science events in London. A science outreach festival that brings research to the pubs.
We have been working since November, reaching out to speakers, booking a venue, advertising and finding fun activities for the day. This has been rewarded with great success: all 3 events sold out and fascinating talks !

We heard about the science behind extremism, discussed the role of social media in shaping teenage brains and learned about morality and dementia. The public was captivated and also very competitive when playing our ‘Guess the Fruit MRI’ ! Thanks to our outstanding speakers and great team of volunteers.

Alizée's Secondment in Paris

by &

Our Zenith student Alizée just completed in April 2022 a short Secondment at Filippo Del Bene's lab at the Institut de La Vision in Paris!

I did a short visit in Filippo Del Bene’s Lab to learn injections from the masters ! The goal was to gain confidence in the use of CRISPR/Cas9 mediated zebrafish Knock-In strategies. With great help from Elena Putti, I did daily injections, screening and went through the protocol to test the efficiency of my designed guides. Back at UCL, I want to setup my own injection routine in the lab and hopefully make transgenic lines with expression in the Preoptic Area or Caudal Hypothalamus.


ZENITH student retreat in Palermo

by , , &

The student retreat was an opportunity to create synergies amongst the ZENITH students and their projects and to develop creative solutions through scientific discussion. The students had the chance to discuss their progress and to share challenges, pitch ideas and propose solutions in an informal, comfortable manner.

It takes a village to raise a PhD student, they say, and my peers have indeed made this weekend of science extremely fulfiling. We learnt about each other's projects, discussed good coding practices, got new ideas for secondments, shared our emotions, & ate our fill!


The student retreat created the space for candid discussion about the progress of our projects. Despite the broad range of topics covered by ZENITH, everyone was engaged, asked interesting questions, and offered insights and ideas. Every time we get the chance to meet, it’s great to see the development of the projects, but also everyone’s growth in confidence as a researcher. I’m looking forward to seeing the continued achievements of the students in the network!


Scientific research is an adventure which can only go forward. But retreat is also a necessary component of this exciting journey. In Palermo, it was a wonderful opportunity not only to share results and ideas, but also to organize thoughts for the next step. After this retreat, I believe every one of us has confidence and clear plans to develop the project. Look forward to seeing it comes true!


Outreach: "Zebrafish - colourful model organism"

by &

Our Zenith student Tahnee engaged in a fantastic outreach activity with a talk for children aged 7-14 years from the KinderCollege der Dualen Hochschule Baden-Württemberg, Karlsruhe, in Germany, and two Master students. The title of Tahnee's talk was "Zebrafische - Farbenprächtige Modellorganismen" (in english: Zebrafish - colourful model organism).

Well done Tahnee!

Verity's Secondment at Cornell

by &

Our student Verity completed a Secondment in April 2022 in the Bass Lab at the Cornell University, a recently added new partner organisation in Zenith! Verity's project is focused on the vocal motor circuit of Danionella. The Bass Lab are the world leaders in the study of vocal motor circuits in fish. They mainly use midshipman as their model organism but have recently started working with Danionella dracula.

"The main goal of my secondment was to compare the vocalisations of the Danionella dracula at the Bass Lab with that of our Danioenella cerebrum. Using a high-speed video camera, I recorded the fish while they vocalised and was able to see the movement of the swim bladder during sound production. Although they are a closely related species with similar morphology, the structure of the sounds they produce are very different. Going forward, it will be interesting to see how this reflects the similarities and differences in their vocal-motor neural circuits."


Poster presentation at ED3C Scientific days

by &

Our Zenith student Gautam successfully presented his poster "Data-driven discovery of long timescale behavioral strategies during sensory evoked navigation" at L’école doctorale Cerveau, cognition, comportement (ED3C) (Brain, cognition, behaviour Doctoral School) Scientific days, in Paris. Lots of interest and interactions with other PhD students around Gautam's data. Well done!

Tahnee's Secondment at UCL

by &

Our student Tahnee completed a 2-month Secondment at the end of 2021/beginning of 2022 in the Rihel lab at UCL. Tahnee also had the opportunity to work in the Zenith partner lab of Isaac Bianco and to hang out with the London-based Zenith students (Giulia in the picture)!

"During my secondment at the Rihel lab at UCL I had the opportunity to investigate zebrafish sleep-wake behavior across multiple day-night cycles. The open and welcoming atmosphere of the “fish-floor” allowed me to also work with members of the Bianco and Wilson lab – learning about different aspects of zebrafish neuroscience."
