Thanks Silivia! Yes we added a second batch of data since the Laterality conference and roughly doubled the sample size

Thanks Cedric! Yes it was among genes identified in GWAS studies of human brain asymmetry that we found most evidence for asymmetrical expression in the mouse brain - more than among genes from the larger Xenium mouse brain standard panel. Encouraging!

It looks like mice can be useful for understanding some aspects of human brain asymmetry, although differences of gene expression between hemispheres were small. Future studies of e.g. mouse genetic knockouts would need adequate sample sizes to overcome this 6/7

In mouse auditory cortex, various microtubule-associated genes showed evidence for subtle left-right differences. Again the human versions have been linked to brain asymmetry or handedness in previous large-scale studies www.pnas.org/doi/10.1073/... 5/7

Ending the thread with one last illustration of novel avenues opened up by genomics of language-/reading-related traits.
