IoO Seminar Series
08 December 2021, 2:30 pm–5:00 pm
The IoO Seminar Series with a kick-off talk from Dr Takeshi Yoshimatsu from the University of Sussex. The title of the talk: Retinal circuit for seeing colour in nature.
Online - Microsoft Teams Webinar11-43 Bath Street LondonLondonEC1V 9EL
In this series, we will be using a new format that provides opportunities for postdocs, students, staff and PIs to have discussions with the speaker.
The format will be as follows:
- 2:30-3:30pm - Seminar and questions. The talk will be recorded for future viewing on the intranet (all welcome).
- 3:30-4pm - "Tea with the speaker" (for postdocs, students and technical staff). A smaller audience for detailed discussion and further questions.
- 4-5pm - Roundtable discussion (PIs and nominated postdocs/students). An informal open discussion with the speakers.
About the Speaker
at University of Sussex
Vertebrate colour vision starts with the use of spectrally distinct cone-photoreceptors. Cone signals are processed in the first synaptic layer of the visual system, the retina’s outer plexiform layer. However, the nature and implementation of this computation remain poorly understood. Here, by combining multiphoton calcium imaging, electron-microscopy circuit reconstruction and natural scene imaging, we established the complete circuit architecture of outer retinal circuits underlying colour processing in larval zebrafish. From here, we (i) investigated chromatic coding across all cone types in the context of natural scenes, and (ii) further studied how the structure and function of UV-cones across different positions in the eye varies to best support different visual tasks.
