    Cochlear implants have been successful in restoring partial hearing to profoundly deaf people. The success of cochlear implants can be attributed to the combined efforts of scientists from various disciplines, including bioengineering, physiology, otolaryngology, speech science, and signal processing. Each of these disciplines contributed to various aspects of the cochlear implant design. Signal p... View full abstract»

    This article reports on the selectivity experimentally obtained with a hand-made 24-fold 2D array with electrodes spaced at 120 μm in the rat peroneal nerve and extensor digitorum longum muscle. We call the device 2D, as all the electrode tips lie in the same plane. The device itself is a 3D multiple needle array. The design and construction of a 128-fold 3D array in silicon- and glass tec... View full abstract»

    Seizure is a phenomenon occurring in a large percentage of the population in every country of the world. It represents a distinctive indicator of an abnormality in the central nervous system. The main indicators in the EEG that predict a seizure are the presence of focal or multifocal receptive spikes or sharp waves (or both) and focal mono-rhythmic discharges. In this article we discuss the hardw... View full abstract»

    Focusing on a particular feature, the ability to create random rhythms, our study is aimed at the analysis of cognitive performance in patients with schizophrenia, comparing them with normal subjects. We have developed a new cognitive test using methods from nonlinear dynamical systems theory, with the objective of measuring the subject's capacity of developing a random rhythm.

    Cuff electrodes for recording of the electro-neurogram from peripheral nerves were introduced by Hoffer [1974] and Stein, et al. [1975]. The cuffs were used to obtain higher signal amplitudes than previously possible, at least in chronic recordings, and to decrease the pick-up of noise, especially from muscles. Cuff electrodes are relatively stable in long-term recordings, but the stability has ne... View full abstract»

  • Modeling neuronal dynamics-transition during sleep

    We review phenomenology of the dynamics-transition of single neuronal activities during sleep and summarize results of simulation. We study the generation mechanism underlying the dynamics-transition, based on the structural analysis of network attractors under various conditions. From these studies, we discuss what is happening in actual neural networks, with possible contribution to brain functi... View full abstract»

    Biomagnetic approaches to understanding the functional organization of the human brain include (1) transcranial magnetic stimulation (TMS), (2) magnetoencephalography (MEG) by superconducting quantum interference devices (SQUIDs), and (3) the imaging of electrical currents and impedance distributions of the head based on new principles of magnetic resonance imaging (MRI) techniques. These techniqu... View full abstract»

    Patients with frontal-lobe epilepsy comprise the second largest group undergoing epilepsy surgery. It has been reported that the difficulty in localizing the epileptogenic zone in these patients is due to the rapid spread of the epileptiform activity within the frontal lobe and to adjoining regions of the brain. We formulated the question of whether the functional localization of dynamic sources o... View full abstract»

    During the “Decade of the Brain”, brain science is coming to terms with its ultimate problem: understanding the mechanisms by which the immense number of neurons in the human brain interact to produce the higher cognitive functions. The analysis of the brain's natural frequencies opens a new window toward a combined analysis of sensory and cognitive functions at the level of single neu... View full abstract»
