Speaking of balances and bridges...
A preliminary study finds intriguing evidence that neurons in the hippocampus and other brain areas are
self-balancing like a
drain trap.
When a neuron ends up with too many inhibitory inputs or too many excitatory inputs, it cuts off the excess side.
As far as I can tell from skimming the article, the researchers haven't yet figured out HOW the neuron does the balancing. Maybe it just attenuates one side, or maybe it breaks some synapses.
See also how glial cells keep loops balanced. Even more amazing.
