On theoretical neural circuits for counting, and their biological implementation in the #Drosophila brain:
"Our second model uses anti-Hebbian plasticity and only tracks frequencies within four count categories (“1-2-3-many”) ... we show that an implementation of the “1-2-3-many” count sketch exists in the insect mushroom body."

@kristinmbranson @andrew_c_lin @djhsu Proposing explanations as to how described neural circuits work must be (should be) irresistible. Looking forward to many more works like this.
