> "'Most notably, we found that the cortex-wide activity patterns that we observed from different cell types were really distinct," Musall explained. "This means that some brain regions were performing a specific function, such as processing sensory inputs, but this only became visible when measuring the activity of the specific cell type that carried this function.
> 
> "'Conversely, many of these functions were not visible with non-specific imaging data because the activity of different cell types in the region got mixed. The same is true for most brain imaging tools that are routinely used in humans, such as fMRI, where we measure the activity of different brain areas based on oxygen consumption."
> 
> "The findings gathered by Musall and his colleagues delineate the functionally different cortical activity patterns that different types of pyramidal cells in the mouse brain elicit during decision-making. Even if all the cells seemed to play a key role in decision-making, different types exhibited different choice tuning patterns."
