Neuroscientists now can read the mind of a fly

Neuroscientists now can read the mind of a fly. In a study focused on three of the fruit fly's sensory systems, the researchers developed a new tool that uses fluorescent molecules of different colors to tag neurons in the brain to see which connections, or synapses, were active during a sensory experience that happened hours earlier. Mapping the pattern of individual neural connections could provide insights into the computational processes that underlie the workings of the human brain.
