摘要： 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.

摘要： A system and method for monitoring electrophysiological information from a tissue slice includes at least one probe having a plurality of electrodes. The system also comprises a controller configured to select tissue sites to be monitored and to be electrically stimulated. In one variation of the invention, a plurality of multi-electrode proves are managed by the controller. The system may further include a plurality of amplifier modules, one amplifier module associated with each probe. The amplifier module may serve a number of functions including amplifying electrical signals sensed by the electrodes, distributing stimulation signals to selected electrodes, and filtering signals evoked from the tissue sites. The system can provide automatic selection and switching of electrodes for monitoring and stimulating multiple tissue sites. Multiple probes, each adapted to monitor multiple tissue sites, may be associated with the controller such that multiple tissue slices may be interrogated in parallel.

摘要： 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 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.

摘要： 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., EEG, in an in vitro nueronal tissue sample by introducing a stimulating composition comprising compounds that facilitate or mimic the actions of acetylcholine, serotonin, or catecholamines, such as carbachol, or by subjecting the in vitro neuronal sample to electrical stimulation parameters.
