Cortical Encoding Allows us to Hear: Cortical Ear

Hearing is the ability to perceive sound from the auditory periphery to the central auditory cortex. Here, we propose that electrical impulses in the auditory cortex can generate sound to hear without man engagement of the periphery organ. For successive and concurrent monitoring and activation of auditory signals in multiple cortical areas, we have developed graphene-based wearable multichannel electrodes with a user-defined neurostimulator equipped. Our preliminary results demonstrated that cortical stimulation remodels the auditory map, thereby leading to altered perception and behavior. As such, cortical activation contributed to functional recovery from sensory deprivation. For now, whether direct activation of the auditory cortex evokes sound in practice remains undiscovered due to the technical limitation in quickly assessing and stimulating the spectroptemporal signals in a macroscale cortical area. This study is aimed to investigate whether spectrotemporal stimulation in the auditory cortex enables animals to hear using a graphene-based, encoding cortex chip. The results will envision fabrication of a cortical ear for people with communication problems such as the deaf.
