Methods and systems that provide enhanced personal video recorder (“PVR”) and interactive television program guide (“IPG”) functionality are provided. An interactive television application (“application”) may be implemented to provide such functionality. The application may be used to display a list of PVR recordings, to schedule recordings to a PVR, to configure recordings, to view a list of scheduled recordings, to configure recording settings, or to select delete priority settings for recordings. The application may integrate pay-per-view and PVR functionality. The application may send user notifications for changes that are to be made to the recording content of a PVR. Live programming may be buffered by the application using a straight buffers that are created for each new program. Parallel buffers for concurrent programs may be implemented using multiple tuners. Straight buffers may be used in managing or controlling the flow of programming. Television content may be automatically paused when a user is engaged in using the application. Multiple IPGs for different users of a PVR may be implemented. Other PVR related features are also provided.

Intracranial recordings, lesion studies, and the combination of functional imaging with source analysis have produced a solid body of evidence about the generators of the P300 event-related potential. Although it is impossible to square all findings obtained across and within methodologies, a consistent pattern of generators has emerged, with target-related responses in the parietal cortex and the cingulate and novelty-related activations mainly in the inferior parietal and prefrontal regions. Stimulus modality-specific contributions come from the inferior temporal and superior parietal cortex for the visual and from the superior temporal cortex for the auditory modality. The P300 continues to be an important signature of cognitive processes such as attention and working memory and of its dysfunction in neurologic and mental disorders. It is increasingly being investigated as a potential genetic marker of mental disorders. Knowledge about the generators of the P300 will be crucial for a better understanding of its cognitive significance and its continuing clinical application.

The P300: Where in the Brain Is It Produced and What Does It Tell Us?

Mechanisms of human attention: event-related potentials and oscillations.

Constraints from functional magnetic resonance imaging (fMRI) were used to identify the sources of the visual P300 event-related potential (ERP). Healthy subjects performed a visual three-stimulus oddball paradigm with a difficult discrimination task while fMRI and high-density ERP data were acquired in separate sessions. This paradigm allowed us to differentiate the P3b component of the P300, which has been implicated in the detection of rare events in general (target and distractor), from the P3a component, which is mainly evoked by distractor events. The fMRI-constrained source model explained >99% of the variance of the scalp ERP for both components. The P3b was mainly produced by parietal and inferior temporal areas, whereas frontal areas and the insula contributed mainly to the P3a. This source model reveals that both higher visual and supramodal association areas contribute to the visual P3b and that the P3a has a strong frontal contribution, which is compatible with its more anterior distribution on the scalp. The results point to the involvement of distinct attentional subsystems in target and distractor processing.

Event-related potentials (ERPs) during a visual oddball paradigm with button-pressing responses were recorded in 12 right-handed subjects from 32 scalp electrodes. The single equivalent current dipole (ECD) of the target C1 (weak occipito-parietal negativity from 30-80ms) was consistently located at the primary visual cortex. From the 4-ECD localization of the target P1/N1 (temporally coincident frontal positivity and occipito-temporal negativity), it was suggested that this complex reflected activities from distributed sources along both dorsal occipito-parietal and ventral occipito-temporal areas. The stable multiple ECD solutions for the target P3b were chosen as those including the left primary motor and/or sensorimotor dipole and satisfying goodness-of-fit (GOF) of more than 98% and confidence limit (CL) of less than 1mm. The obtained frontal dipoles were discussed in terms of visual working memory and sustained attention in reference to the previous PET, fMRI and MEG studies. The distributed multiple ECDs may suggest that P3 should be interpreted as being the embodiment of the cortico-limbic-thalamic network which involves Halgren and Marinkovic's emotional and behavioral model and Mesulam's attentional circuit.

To contribute to physiology and pathophysiology of the glomerulus of human kidney, we have launched a proteomic study of human glomerulus, and compiled a profile of proteins expressed in the glomerulus of normal human kidney by two-dimensional gel electrophoresis (2-DE) and identification with matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) and/or liquid chromatography-tandem mass spectrometry (LC-MS/MS) Kidney cortices with normal appearance were obtained from patients under surgical nephrectomy due to renal tumor, and glomeruli were highly purified by a standard sieving method followed by picking-up under a phase-contrast microscope The glomerular proteins were separated by 2-DE with 24 cm immobilized pH gradient strips in the 3-10 range in the first dimension and 26 x 20 cm sodium dodecyl sulfate polyacrylamide electrophoresis gels of 125% in the second dimension Gels were silver-stained, and valid spots were processed for identification through an integrated robotic system that consisted of a spot picker, an in-gel digester, and a MALDI-TOF MS and / or a LC-MS/MS From 2-DE gel images of glomeruli of four subjects with no apparent pathologic manifestations, a synthetic gel image of normal glomerular proteins was created The synthetic gel image contained 1713 valid spots, of which 1559 spots were commonly observed in the respective 2-DE gels Among the 1559 spots, 347 protein spots, representing 212 proteins, have so far been identified, and used for the construction of an extensible markup language (XML)-based database The database is deposited on a web site (http://wwwswneccojp/bio/rd/hgldb/indexhtml) in a form accessible to researchers to contribute to proteomic studies of human glomerulus in health and disease

A broadcast storage system is disclosed which is easily controllable by the user for setting programs for timer recording and playing back recorded programs. The broadcast storage system has one or more slave apparatus and a master apparatus. The master apparatus grasps programs set for timer recording by each of the slave apparatus. When a program to be recorded is determined by the user or an automatic timer recording process, the master apparatus selects an apparatus to record the program such that a plurality of timer recording settings are not made at one time in one apparatus, and instructs the selected apparatus to set the program for timer recording. When instructed to set the program for timer recording, a slave apparatus sets the program for timer recording, and records the program at the time when the program is broadcast.
