Cortical plasticity and the bi-directional
Brain Machine Interface
The brain machine interface (BMI) has undergone considerable development in the past 10 years, but with few exceptions, has remained entirely an efferent interface. We have begun work to develop an afferent interface to provide proprioceptive feedback to monkey subjects using stimulation through multi-electrode arrays implanted in somatosensory cortex. We are also investigating the plastic changes that occur within the cortex as a result of the Hebbian associations that result when this stimulation occurs in close synchrony with spiking activity in other parts of the brain. Ultimately, we hope to combine the afferent and efferent interfaces in a single animal, and to use appropriately patterned stimulation to drive plastic changes that would assist the monkey’s natural adaptation
