Porcini belong to the Boletus genus of
mushrooms, characterized by a soft, meaty white
body that does not change color
after it is cut.
Using real - time cellular imaging to monitor the changes in aged flies» neuron activity before and
after learning, Davis and his colleague Ayako Tonoki found structural connectivity defects between a set of neurons known as dorsal paired medial neurons and
mushroom body neurons; these defects prevented long - term memories from forming.
