A new therapy could improve memory by "sending electrical pulses to aid the brain when it is struggling to store new information." I'm trying to figure out how this works physically, in terms of how it actually helps the brain. I would imagine that it has something to do with the neurons getting past the threshold for firing a signal with more ease, but is this because the threshold is suddenly lower because of the presence of the current, or what?
Could anyone provide me with an explanation of the science behind this in lay terms?
Many many thanks
