Our on-going work to develop an intracortical visual prosthesis has motivated the design, fabrication, and testing of a Wireless Floating Microelectrode Array (WFMA) stimulator. This implantable device can be used for an electrical stimulation interface in the peripheral and the central nervous system. Previously, its use in a sciatic nerve rodent model was described. Here implantation of two WFMAs...
Surgical resection of epileptogenic foci is often a beneficial treatment for patients suffering debilitating seizures arising from intractable epilepsy [1], [2], [3]. Electrodes placed subdurally on the surface of the brain in the form of an ECoG array is one of the multiple methods for localizing epileptogenic zones for the purpose of defining the region for surgical resection. Currently, transcutaneous...
In this paper, we consider that cooperative frequency spectrum sensing based on the spatial spectral estimation in cognitive radio sensor networks. We propose an algorithm that estimates the interference temperature of this model using a generalization of the DOA (direction of arrival) algorithm. From this, we find the interference temperature and show that it does become smaller. We compare our method...
