Reusing the LM4041 voltage regulator to create a precision current source by leveraging the CATHODE pin as a sense pin.

“It is no use asking for the impossible, such as, say, the exact wiring diagram for a cubic millimeter of brain tissue and the way all its neurons are firing,” Crick wrote in Scientific America ...

Researchers have created the largest and most detailed wiring diagram of a mammalian brain so far, by mapping cells in 1 cubic millimetre of a mouse’s brain tissue 1. In a landmark achievement ...
