When you're working or studying, what do you have on in the background? Perhaps a podcast, music of some kind, or maybe complete silence? Evidence suggests that certain types of music might help or indeed hinder our attempts to learn.
A new study reviewing past research makes the case that random, artificially generated noise has the potential to help the brain learn better.learning by increasing the brain's plasticity, or ability to take on new information – essentially, helping the brain form new paths and connections.transcranial random noise stimulationtRNS involves placing electrodes on a person's scalp and passing weak electrical currents through specific parts of the brain.
"So, people with learning difficulties [could] use it to enhance learning rate, for example. It's also been trialed on people with visual deficits, such as after stroke and traumatic brain injury." The newly published paper doesn't involve any new research but summarizes a host of previous studies on tRNS. Overall, adding brain stimulation during periods of study can improve learning and helps with attention after the treatment, too.
Based on past research, tRNS can have two effects: an 'acute' effect where learning is enhanced while tRNS is applied, and a longer-term, modulating effect where cognitive performance can be improved in the future, even after tRNS has stopped being used.
