>This an impressive simulation. But it's just not honest to call this 'brain emulation', a 'brain upload' or to say that this is doing anything like 'sensorimotor loop in simulation'. Aside from the fact that a connectome is not a brain, and so we have no idea whether the parts that have been filled in by ML actually function like a brain, the motor control in this framework is not even driven by the brain simulation. The output from the 'brain' is not a sequence of motor commands. It is a steering mechanism, a 2-dimensional descending signal (essentially, turn left or right, speed up or slow down). That is then fed into a series of CPG oscillators, outside of the brain emulation, that model fly movement in response to that 2-dimensional descending signal. Since outputting a 2-dimensional descending signal is not what a fly brain does, the simulated brain is not operating as a fly's brain does. It's machine learning, clamped into the shape of a fly connectome, that has a resting state of 0Hz, being zapped with simple inputs, not virtual sensory data.
Nevertheless a worrying direction.
