    Understanding Brain Signals in Brain-Computer Interfaces



    Understanding Brain Signals in Brain-Computer Interfaces

    Introduction

    Brain signals form the bedrock of Brain-Computer Interfaces (BCIs), providing crucial insights into how the brain communicates through electrical activity. BCIs analyze these signals, typically captured through EEG (electroencephalography), ECoG (electrocorticography), or implanted electrodes. The ability to interpret these brain signals represents a significant breakthrough in neuroscience and technology, holding transformative potential for rehabilitation, communication, and augmenting human capabilities. In this article, we delve into the mechanisms of brain signal interpretation and explore its pivotal role within the field of BCIs.
