Within the nervous system  primary cilia contribute to signaling and sensory perception  while motile cilia facilitate cerebrospinal fluid flow. Here  we investigated the impact of ciliary loss on neural circuit development using a zebrafish line displaying ciliogenesis defects. We found that cilia defects post neurulation affects neurogenesis and brain morphology  especially in the cerebellum  and lead to altered gene expression profiles. Using whole brain calcium imaging  we measured reduced light evoked and spontaneous neuronal activity in all brain regions. By shedding light on the intricate role of cilia in neural circuit formation and function in the zebrafish  our work highlights their evolutionary conserved role in the brain and set the stage for future analysis of ciliopathy models. Overall design: To analyse the impact of cilia loss on gene expression  we performed RNA sequencing analysis of 4 dpf elipsa mutant and sibling control zebrafish larvae. We extracted total RNA from mutant selected based on their curly tail down phenotype and sibling controls mixture of heterozygous and wild type. RNAsequencing was performed on 4 different clutches.", null, "pubmed:38868197", null, "elipsa control  clutch 1", "GSM7808255", null, "source name:whole larvae|tissue:whole larvae|genotype:mixture wt and +/ |treatment:no treatment|geo loc name:missing|collection date:missing", "elipsa control  clutch 1", "Standard processing by BGI.

To lyse the samples  500\u03bcL trizol was added and the euthanized larvae were homogenized through a 27 gauge needle until the mixture looked uniform. post adding another 500\u03bcL trizol  the samples were incubated for 5 minutes at room temperature. The larvae were then treated with 200\u03bcL chloroform  and the tube was rocked for 15secs to mix the contents.
