  • Publication number: 20040137515
    Abstract: This invention relates to methods for the detection and characterization of psychoactives in neuronal tissue by comparing parameters measured for a set of baseline oscillations with those same parameters measured for a set of resulting oscillations. The baseline oscillations are induced or stimulated by such agents as chemical compounds that effect cholinergic interactions, co-deposited neuronal tissue, or electrical stimulations. The resulting set of oscillations is obtained after exposing the neuronal tissue to a sample composition that may or may not contain a psychoactive. By comparing the parameters for the baseline and resulting oscillations, the psychoactive in the sample composition may be detected and characterized as belonging to a specific psychoactive compound class and in some instances, may be distinguished from other members of the psychoactive compound class.

  • Patent number: 6511817
    Abstract: This relates to methods for the detection of psychoactive compounds in an in vitro neuronal tissue sample by detecting oscillations of extracellular voltage desirably before and after the introduction of a candidate sample onto an in vitro neuronal tissue sample and for devices useful in practicing the methods. Analysis of the extracellular voltage parameters leads to indication of the presence of psychoactive material in the candidate sample and information as to its pharmacological activity and/or composition. Further, it relates to a process of initiating and maintaining the presence of repetitive neuronal activity within the in vitro sample. Additionally, this includes a method for the stimulation of or initiation of repetitive neuronal activity, e.g.

  • Patent number: 6132683
    Abstract: This invention relates to a low impedance cell potential measuring electrode assembly typically having a number of microelectrodes on an insulating substrate and having a wall enclosing the region including the microelectrodes. The device is capable of measuring electrophysiological activities of a monitored sample using the microelectrodes while cultivating those cells or tissues in the in the region of the microelectrodes. The invention utilizes independent reference electrodes to lower the impedance of the overall system and to therefore lower the noise often inherent in the measured data. Optimally the microelectrodes are enclosed by a physical wall used for controlling the atmosphere around the monitored sample.

  • Patent number: 5748305
    Abstract: A method for foreign particles inspection includes illuminating an inspection surface of an inspection object with a beam which is, one of s-polarized and p-polarized relative to the inspection surface of the inspection object. The illumination utilizes an optical axis which is generally parallel to the inspection surface or which intersects the inspection surface at an angle that is greater than or equal to 1.degree. and less than 5.degree.. Reflected and scattered light is detected utilizing an optical axis which makes an acute angle with the inspection surface and which makes a differential angle of 30.degree. or less with the optical axis of the illumination beam. The detection of foreign particles is accomplished by detecting the component of the reflected and scattered light which is the other of s-polarized and p-polarized relative to the inspection surface.
