Efficient stimulation inducing neural activity in retinal implant

IEEE SMC'99 Conference Proceedings. 1999 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.99CH37028), 1999

Electrical stimulation to the nervous system is important in visual prostheses. In this study, we stimulated the central nervous system of an experimental animal in various ways, and the neural response has been evaluated from both biological and computational points of view. Experimental results have revealed that the anode/cathode distance seems to play an important role to reduce the energy ...

Therefore there is a need for spatial and time multiplexing techniques to provide improved performance of the current technology. In particular, bright and high-contrast visual scenes may require simultaneous activation of several electrodes. In ...

Generating virtual channels in retinal prostheses

However, channels interaction, or virtual channels, can be used in a controlled manner to increase the number of perceptible electrodes for retinal prosthesis patients. Virtual channels have been used successfully in the cochlear prosthesis systems to increase the number of perceptible channels or electrodes. In this paper, ...

  • Efficient stimulation inducing neural activity in retinal implant

    Electrical stimulation to the nervous system is important in visual prostheses.

Experimental results have revealed that the anode/cathode distance seems to play an important role to reduce the energy consumption.

  • Cortical responses following simultaneous and sequential retinal neurostimulation with different return configurations

    Researchers continue to develop visual prostheses towards safer and more efficacious systems. However limitations still exist in the number of stimulating channels that can be integrated. Therefore there is a need for spatial and time multiplexing techniques to provide improved performance of the current technology. In particular, bright and high-contrast visual scenes may require simultaneous activation of several electrodes. In this research, a 24-electrode array was suprachoroidally implanted in three normally-sighted cats. Multi-unit activity was recorded from the primary visual cortex. Four stimulation strategies were contrasted to provide activation of seven electrodes arranged hexagonally: simultaneous monopolar, sequential monopolar, sequential bipolar and hexapolar. Both monopolar configurations showed similar cortical activation maps. Hexapolar and sequential bipolar configurations activated a lower number of cortical channels. Overall, the return configuration played a more relevant role in cortical activation than time multiplexing and thus, rapid sequential stimulation may assist in reducing the number of channels required to activate large retinal areas.

  • Visual perception of low quality images

    There are several new applications where perception is required from low quality images. One such application are electronic visual prostheses, or "bionic eyes". These artificial vision systems involve electrical stimulation of nerve cells in the human visual system via implanted electrodes. In this paper we present results of our subjective tests based on simulating what might be seen by users of low quality vision systems. 225 normally sighted subjects viewed a set of low quality (low spatial resolution and low grey- scale) static images. We wished to quantify intelligibility/recognition for low quality images. Results from this testing form part of an image quality model to assess the usefulness of low quality images.

  • Generating virtual channels in retinal prostheses

    Channel interaction generated by simultaneous electrical stimulation of neighboring electrodes is generally undesirable. However, channels interaction, or virtual channels, can be used in a controlled manner to increase the number of perceptible electrodes for retinal prosthesis patients. Virtual channels have been used successfully in the cochlear prosthesis systems to increase the number of perceptible channels or electrodes. In this paper, we analyze and study the condition for generating virtual channels in retinal prostheses. A finite element model of the retina with four electrodes was created. The conditions for generating virtual channels were studied by adjusting the ratio of the input voltage applied to neighboring electrodes. Experimental studies in cochlear prostheses show the existence and usefulness of virtual channels.

  • Wireless ultra-wide-band data link for biomedical implants

    The potential of wireless ultra-wide-band (UWB) technology for data links in biomedical implants is discussed. Most current technologies have been proven unsuitable for use in future high complexity applications. Emerging systems such as vision prosthesis will require significantly higher data rates and power efficiency. UWB offers unique properties that make it an attractive candidate to meet the increased demand. Furthermore, initial results of an UWB transceiver design are reported. A pulse generator and a wide-band LNA have been designed and fabricated in a 65 nm CMOS technology. Test results are also presented.

  • Silicon based microstructures suitable for intracortical electrical stimulation (visual prosthesis application)

    The authors have produced a 0.4-mm*0.4-mm*1.6-mm, three-dimensional, silicon- based microstructure which can be used for stimulation of cortical neurons. The structure consists of 100 pyramidal-shaped needles, each 1.5 mm long with a base about 0.06 mm on a side. The entire structure is passivated with silicon nitride except for the tips of the needles, which are coated with platinum. The mechanical properties of these structures and the tissue reaction to them were studied in cat cortex. Impact insertion of the arrays produces good implantation with minimal tissue insult. Preliminary histological studies suggest that cortical tissues are not adversely affected by these microstructures.<<ETX>>

  • An inductive link for an intracortical visual prosthesis

    Wireless operation is highly desirable for implanted neural prostheses used for neural stimulation or recording on many channels, whether the goal is to restore lost motor function or sensory capability in humans or to perform neuroscience research in animals without transcutaneous leads. However, the necessarily small size of stimulating and recording implants poses certain challenges in constructing an inductive link to wirelessly power and communicate with the implant. The objectives of this research are: first, to design an inductive link to provide power and control data to a 16-channel electrode array, which is small enough to be implanted beneath the dura for use in an intracortical visual prosthesis, and second, to develop a method of fabricating the implanted side of the inductive link in a manner which is reliable and reproducible.

  • Retina implant adjustment with reinforcement learning

    A tuning method with reinforcement learning (RL) for the retina encoder (RE) of a retina implant (RI) as a visual prosthesis for blind subjects with retinal degenerations is proposed. The RE simulates retinal information processing in real time by means of spatio-temporal receptive field (RF) filters and generates electrical signals for stimulation of several hundreds of ganglion cells (GC) to regain a modest amount of vision. For each contacted GC, the RE has to be optimized with regard to the patient's perception. The patient's (for the present simulated) evaluative feedback is applied here in a dialog module as a reinforcement signal to train several RL agents in a neural network learning process.

  • The Processing and Control of Neuro-stimulator for Visual Prostheses based on FPGA

    A novel processing and control design of neuro-stimulator in visual prostheses based on optic nerve stimulation is proposed in this paper. The design is capable of controlling the electrodes drivers with the style of subboard and mainboard to generate biphasic stimulus current with different patterns.
