Abstract:
The present invention relates to methods of identifying genes involved in memory formation. This is accomplished by performing a gene chip identification of those genes expressed during transcription-dependent memory formation but not during transcription-independent memory formation. A statistical analysis of the gene chip identification output yields a set of genes that are involved in transcription-dependent memory formation.
Abstract:
The present invention provides methods of treating cognitive deficits associated with mental retardation. The methods comprise combining cognitive training protocols and a general administration of phosphodiesterase 4 inhibitors.
Abstract:
There is provided a video message system that includes a video display, a frame, and at least one video camera. The video display, which has a fixed position, plays back a video portion of a video message from a user. The frame frames the video display. The at least one video camera is disposed on the frame, and is oriented in the same direction as the video display, for capturing video data of the user for inclusion in the video portion of the video message.
Abstract:
The present invention provides methods for screening a pharmaceutical agent for its ability to modulate long term memory formation, performance of a hippocampal-dependent cognitive task or STAUFEN function. The present invention also provides methods for modulating long term memory formation or performance of a hippocampal-dependent cognitive task by modulating staufen-dependent protein expression. The present invention further provides methods for treating a defect in long term memory formation associated with a defect in STAUFEN and methods for treating a defect in performance of a hippocampal-dependent cognitive task associated with a defect in STAUFEN.
Abstract:
Methods for purifying a polypeptide from a composition comprising the polypeptide and at least one contaminant are described, which methods comprise the sequential steps of: (a) passing the composition through an ion exchange membrane, where the polypeptide and the membrane have opposite charge, at operating conditions comprised of a buffer having a pH sufficiently distinct from the pI of the polypeptide to enhance the charge of the polypeptide and a low ionic strength effective to prevent the shielding of charges by buffer ions, which cause the membrane to bind the polypeptide and the at least one contaminant, and (b) recovering the purified polypeptide from the effluent.
Abstract:
While a device is offline, usage data is tracked on the device. The usage data is uploaded to a server after the device is again connected to a network. Applications that run on mobile devices typically embed a browser to display content. Unfortunately, mobile devices also frequently disconnect from the associated network. A system tracks usage data by using JavaScript in the browser to communicate with the native device, which then buffers the usage data for future upload. This is done by installing, in each application, a “protocol handler” that listens for a request over a particular protocol. The protocol handler intercepts the requests and stores the usage data locally on the device. Subsequently, when the device detects network connectivity, the device uploads the data to servers that collect data for aggregation and presentation.
Abstract:
The present invention provides methods for identifying cognitive enhancers able to enhance CREB pathway function. Cognitive enhancers identified in accordance with the invention can be used in rehabilitating an animal with cognitive dysfunctions and for enhancing memory or normal cognitive performance (ability or function) in a normal animal.
Abstract:
Methods of assessing the effect of a drug on long term memory and for screening a pharmaceutical agent for its ability to modulate long term memory are disclosed.
Abstract:
The invention pertains to a novel gene present in cytological region 37D of the second chromosome which functions in associative learning and/or memory. Disruption of the gene, such as by P element transposon-tagged insertion, results in decreased associative learning and/or memory. The invention also pertains to a novel protein encoded by the gene, antibodies which bind the encoded protein, and homologs of the novel gene which function in associative learning and hybridize to the DNA sequence of the novel gene.
