Every scientist, long before they were a scientist, was a little kid who stood in front of a fish tank or stared up at the stars or turned over a rock to look at the bugs underneath and said “wow”. On the best days, working in science still feels like that.

The architecture of the human default mode network explored through cytoarchitecture, wiring and signal flow - Nature Neuroscience
The default mode network (DMN) is implicated in cognition and behavior. Here, the authors show that the DMN is cytoarchitecturally heterogeneous, it contains regions receptive to input from the sensory cortex and a core relatively insulated from environmental input, and it uniquely balances its output across sensory hierarchies.
