Automated behavioural analysis reveals the basic behavioural repertoire of the urochordate Ciona intestinalis
Rudolf, Jerneja; Dondorp, Daniel; Canon, Louise; Tieo, Sonia; Chatzigeorgiou, Marios (Journal article; Peer reviewed, 2019-02-20)Quantitative analysis of animal behaviour in model organisms is becoming an increasingly essential approach for tackling the great challenge of understanding how activity in the brain gives rise to behaviour. Here we used ... -
Ciona spp. and ascidians as bioindicator organisms for evaluating effects of endocrine disrupting chemicals: A discussion paper
Beyer, Jonny; Song, You; Lillicrap, Adam David; Rodríguez-Satizábal, Simón; Chatzigeorgiou, Marios (Journal article; Peer reviewed, 2023)In context of testing, screening and monitoring of endocrine-disrupting (ED) type of environmental pollutants, tunicates could possibly represent a particularly interesting group of bioindicator organisms. These primitive ... -
Comprehensive analysis of locomotion dynamics in the protochordate Ciona intestinalis reveals how neuromodulators flexibly shape its behavioral repertoire
Athira, Athira; Dondorp, Daniel; Rudolf, Jerneja; Peytral, Olivia; Chatzigeorgiou, Marios (Journal article; Peer reviewed, 2022)Vertebrate nervous systems can generate a remarkable diversity of behaviors. However, our understanding of how behaviors may have evolved in the chordate lineage is limited by the lack of neuroethological studies leveraging ... -
Do DOM quality and origin affect the uptake and accumulation of a lipid-soluble contaminant in a filter feeding ascidian species (Ciona) that can target small particle size classes?
Schultze, Sabrina; Langva, Hilde K.; Wei, Jing; Chatzigeorgiou, Marios; Rundberget, Thomas; Hessen, Dag Olav; Ruus, Anders; Andersen, Tom; Borgå, Katrine (Journal article; Peer reviewed, 2024)The widely reported increase of terrestrial dissolved organic matter (terrDOM) in northern latitude coastal areas (“coastal darkening”) can impact contaminant dynamics in affected systems. One potential impact is based on ... -
The ion channel Anoctamin 10/TMEM16K coordinates organ morphogenesis across scales in the urochordate notochord
Liang, Zonglai; Dondorp, Daniel; Chatzigeorgiou, Marios (Journal article; Peer reviewed, 2024)During embryonic development, tissues and organs are gradually shaped into their functional morphologies through a series of spatiotemporally tightly orchestrated cell behaviors. A highly conserved organ shape across ... -
Mesmerize is a dynamically adaptable user-friendly analysis platform for 2D and 3D calcium imaging data
Kolar, Kushal; Dondorp, Daniel; Zwiggelaar, Jordi Cornelis; Høyer, Jørgen; Chatzigeorgiou, Marios (Journal article; Peer reviewed, 2021)Calcium imaging is an increasingly valuable technique for understanding neural circuits, neuroethology, and cellular mechanisms. The analysis of calcium imaging data presents challenges in image processing, data organization, ... -
Neuronal gene expression in two generations of the marine parasitic worm, Cryptocotyle lingua
Tolstenkov, Oleg; Chatzigeorgiou, Marios; Gorbushin, Alexander (Journal article; Peer reviewed, 2023)Trematodes, or flukes, undergo intricate anatomical and behavioral transformations during their life cycle, yet the functional changes in their nervous system remain poorly understood. We investigated the molecular basis ... -
Pax3/7 gene function in Oikopleura dioica supports a neuroepithelial-like origin for its house-making Fol territory
Lagman, David Arthur Erik; Leon Florian, Luis Anthony; Cieminska, Nadia; Deng, Wei; Chatzigeorgiou, Marios; Henriet, Simon Raymond; Chourrout, Daniel Marc (Journal article; Peer reviewed, 2024)Larvacean tunicates feature a spectacular innovation not seen in other animals - the trunk oikoplastic epithelium (OE). This epithelium produces a house, a large and complex extracellular structure used for filtering and ... -
Polymodal sensory perception drives settlement and metamorphosis of Ciona larvae
Høyer, Jørgen; Kolar, Kushal; Athira, Athira; van den Burgh, Meike; Dondorp, Daniel; Liang, Zonglai; Chatzigeorgiou, Marios (Journal article; Peer reviewed, 2024)The Earth’s oceans brim with an incredible diversity of microscopic lifeforms, including motile planktonic larvae, whose survival critically depends on effective dispersal in the water column and subsequent exploration of ...
