5 things I learned on Sunday at #sfn16

Just some irrelevant facts.

1. Toadfish can sing by vibrating their swim bladder, and can vocalize independent of breathing.

2. Scientists working in Drosophila are starting to see reafferent signals (signals representing motor commands such as walking or singing) in tons of places, from sensory neurons on downward. This is one of the areas where Drosophila neuroscientists are way ahead of mammalian neuroscientists.

3. The computations that visual neurons perform can fundamentally alter in conditions that seem like they should be similar, such as light levels (this is not just adaptation to statistics).

4. There are conditions in which retinal neurons can be synergistic and not redundant. This is a bit of a controversy in the field, with the common consensus that ganglion cells have ~10% redundancy. Apparently this is not always the case!

5. Drosophila (fruit flies) have a spatial short term memory that has been located in the central complex (actually, I am not clear exactly where the anatomical structure is located: it may be just outside of the central complex.)
