The compartments

16 compartments, each signed by its own dopamine input: 8 appetitive, 7 aversive, 1 unsigned.

The rule

Count the PAM and PPL1 presynapses inside a compartment; the sign of their ratio is its sign. Under 100 presynapses, no sign.

A close-up of one compartment: a long solid bar for its PAM presynapses over a short dithered bar for its PPL1 presynapses, then the log ratio, the tanh strength and the sign derived from them.
One compartment, close up. The calyx has 1 dopaminergic presynapse, so it gets none.

Every sign

Presynapses counted in neuPrint male-cns:v1.0, one row per compartment.

A signed bar chart with one row per mushroom body compartment: PAM and PPL1 presynapse counts on the left, then a bar that runs right for appetitive and left, dithered, for aversive, with the log ratio at the far right.

The counts behind it

The log ratio carries a pseudo-count of one on each side; MBONs are as the build assigned them.
