In order to fully appreciate brain interface technology, one must go back to the basics of neuroscience. The nervous system (consisting of the spinal cord and the brain) is made up of cells called neurons, which have the unique characteristic of being able to communicate with each other using electrical signals, through connections called neural synapses (2). Using this communication system, one neuron can send an electrical “message” to another neuron or even to an entire network of neurons, allowing for an immense number of possible firing patterns. This complexity is the primary reason why, to this day, the exact mechanisms by which neural firing patterns create phenomena like memory, consciousness, sensory experience, and motor action remain largely unknown.
