摘要： A neural probe is disclosed for optically stimulating or silencing neurons and recording electrical responses to the stimulus. Using patterning techniques, an integral optical waveguide may be fabricated on the probe for transmitting neuron-affecting light from a light source to a probe tip. The probe tip may include one or more electrodes to receive electrical responses from stimulated neurons for recording or further processing. According to various embodiments, the disclosed neural probes may utilize multiple light sources simultaneously, switch between multiple light sources, or utilize a single light source to stimulate or silence multiple neuron locations simultaneously via multiple probe tips or via multiple light-emitting sites located along the length of the probe. Neural probes are thereby provided that have sufficient spatial resolution to accurately target, stimulate, and record the reaction of neurons, or as few as a single neuron, utilizing a slim, compact structure.

摘要： A bioamplifier that includes a high pass filter, open-loop amplifier, and low pass filter in an area efficient design that can be used in implantable neural interfaces. The high pass filter can be implemented by using a switch-capacitance resistor coupled with parasitic capacitance of the electrode. The amplifier can be chopper stabilized and can include a high gain, current-ratio first stage followed by one or more dimension-ratio stages. The low pass filter utilizes the output impedance of the open-loop amplifier to form an embedded gm-C low pass filter.

摘要： The present invention relates to a distributed oscillator, and more particularly, to a high frequency distributed oscillator using coupled transmission lines. According to the present invention, coupled transmission lines capable of increasing the frequency selectivity are used as transmission lines. Signal interference occurs among the coupled transmission lines because of mutual approximation. The coupled transmission lines serve as a filter due to the signal interference. A phase noise characteristic can be thus increased.

摘要： A neural probe (10) is provided for in vivo communication with biological tissue, including stimulating neurons and/or recording neural electrical activity. The probe (10) may be constructed so that the immune response by the biological tissue in which the device is implanted is reduced over known implantable probes. The probe (10) can be constructed with a tip (16) that has a branched configuration, with electrodes (24) located along each of the branches (20). A biodegradable coating (18) is disposed over at least the tip (16) of the probe (10) to provide the probe (10) with sufficient integrity for insertion into the biological tissue and to degrade after insertion. The biodegradable coating (18) can have an anti-inflammatory drug or other bioagent distributed therein for localized release of the bioagent to further reduce the immune response.

摘要： A microfluidic chamber for use in individual cell assays. The microfluidic chamber includes a cell microchamber having an interior region and front and rear valves, each of which are separately controllable so that they can be selectively opened and closed to thereby permit the transference of an individual cell into and out of the interior region. Cell secretion and contact interaction studies can be carried out using the microchambers, with the valves permitting either complete isolation or perfusion media flow through the microchambers. An internal perfusion wall can be included to partition the microchamber for non-contact perfusion studies of secretion interactions between cells.
