Neuroscientists uncovered an energy-saving mode in vision-system neurons that works at the cost of being able to see fine-grained details.
of the French National Center for Scientific Research and ESPCI Paris discovered that when flies are starving, a brain pathway needed to form an energetically costly type of long-term memory shuts down. When they forced the pathway to activate and form memories, the starving flies died much faster—which suggests that turning off that process conserved energy and preserved their lives.
The new paper offers the first look into how the brain adapts to save energy once food has been scarce, but not nonexistent, for a long while. The researchers then started eavesdropping on the conversations between the mice’s neurons. They measured the number of voltage spikes—the electrical signals neurons use to communicate—sent out by a handful of neurons in the visual cortex when mice viewed images of black bars oriented at different angles. Neurons in the primary visual cortex respond to lines with preferred orientations.
