eli5: How computer read brain signal

433 views

Computer can read electromagnetic wave by transferring them from frequencies into binary code. ( correct me if im wrong). But how computer can turn brain signal into binary code and predict the movement of the individual ( such as monkey playing a game) how does human so powerful that they created binary code for one specific alphabet and it is same as what brain use it for the specific alphabet. For example, the binary code for letter A is 00001 and how does the brain come out with the same as well. or my understanding is wrong, pls help.

If brain imaging is sensing em waves like with eeg, it’s sensing macro wave patterns in various regions of the brain, not individual neurons or anything. MRI senses blood flow in brain blood vessels & afaik can give more detailed imagery. They can now detect some individual neuron activity (I think it’s invasive though). I’m no neurosurgeon though, so grain of salt.
