Which is a long way round of saying: a lot of the pieces I’m reading on the crucial role of the BBC massively overweight news and underplay the wider role of 50 odd radio stations, a dozen TV stations and the vast majority of its output.

Statistical analysis of connectivity within the central brain shows that around 6.5% of synaptic connections in the male and 1.3% of connections in the female are dimorphic. In the male, sex-specific circuit elements form highly interconnected clusters with similar connectivity. 9/10

Comparing the EM neurons to light microscopy datasets of fruitless and doublesex expression, we annotated the putative expression pattern of these genes for both the male and female connectomes. 7/10

We cross-matched neurons and identified over 7k isomorphic, 114 sexually dimorphic, 262 male- and 69 female-specific cell types. In total, these neurons make up 4.8% and 2.4% of the male and female brain, respectively. 6/10

As the first (and so far, only) male brain, we compared this connectome to the previously published #FlyWire #FAFB female dataset to investigate the structural differences across male and female brain connectomes. 5/10
