Improving memory with magnets

The ability to remember sounds, and manipulate them in our minds, is incredibly important to our daily lives – without it we would not be able to understand a sentence, or do simple arithmetic. New research is shedding light on how sound memory works in the brain, and is even demonstrating a means to improve it.

Scientists previously knew that a neural network of the brain called the dorsal stream was responsible for aspects of auditory memory. Inside the dorsal stream were rhythmic electrical pulses called theta waves, yet the role of these waves in auditory memory were until recently a complete mystery.
