BACKGROUND To investigate the long-latency activities common to all sensory modalities, electroencephalographic responses to auditory (1000 Hz pure tone), tactile (electrical stimulation to the index finger), visual (simple figure of a star), and noxious (intra-epidermal electrical stimulation to the dorsum of the hand) stimuli were recorded from 27 scalp(More)
MOTIVATION A question that often comes up after applying a motif finder to a set of co-regulated DNA sequences is whether the reported putative motif is similar to any known motif. While several tools have been designed for this task, Habib et al. pointed out that the scores that are commonly used for measuring similarity between motifs do not distinguish(More)
BACKGROUND The characterization of DNA replication origins in yeast has shed much light on the mechanisms of initiation of DNA replication. However, very little is known about the evolution of origins or the evolution of mechanisms through which origins are recognized by the initiation machinery. This lack of understanding is largely due to the vast(More)
Isolated microtubule-associated protein 2 (MAP2), tau factor, and tubulin were phosphorylated by a purified Ca2+, calmodulin-dependent protein kinase (640K enzyme) from rat brain. The phosphorylation of MAP2 and tau factor separately induced the inhibition of microtubule assembly, in accordance with the degree. Tubulin phosphorylation by the 640K enzyme(More)
The quick detection of dynamic changes in multisensory environments is essential to survive dangerous events and orient attention to informative events. Previous studies have identified multimodal cortical areas activated by changes of visual, auditory, and tactile stimuli. In the present study, we used magnetoencephalography (MEG) to examine time-varying(More)
We developed a visual 3D model of a space module and analyzed whether activity in the auditory cortex is influenced by rotating the image using magnetoencephalography. We presented 1,000 Hz pure tone as an auditory stimulus in four different visual conditions: (1) RR: a virtual image rotated around the center, (2) VR: images rotated vertically, (3) HR:(More)
X11-like (X11L) is neuronal adaptor protein that interacts with the amyloid beta-protein precursor (APP) and regulates its metabolism. The phosphotyrosine interaction/binding (PI/PTB) domain of X11L interacts with the cytoplasmic region of APP695. We found that X11L-APP interaction is enhanced in osmotically stressed cells and X11L modification is required(More)
BACKGROUND To segregate luminance-related, face-related and non-specific components involved in spatio-temporal dynamics of cortical activations to a face stimulus, we recorded cortical responses to face appearance (Onset), disappearance (Offset), and change (Change) using magnetoencephalography. RESULTS Activity in and around the primary visual cortex(More)
The neural mechanisms underlying unimodal spatial attention have long been studied, but the cortical processes underlying cross-modal links remain a matter of debate. To reveal the cortical processes underlying the cross-modal links between vision and touch in spatial attention, we recorded magnetoencephalographic (MEG) responses to electrocutaneous stimuli(More)
We have previously isolated two Ca2+, calmodulin-dependent protein kinases with molecular weights of 120,000 (120K enzyme) and 640,000 (640K enzyme), respectively, by gel filtration analysis from rat brain. Chicken gizzard myosin light-chain kinase and the 120K enzyme phosphorylated two light chains of brain myosin, whereas the 640K enzyme phosphorylated(More)
