Category-Specific Visual Responses: An Intracranial Study Comparing Gamma, Beta, Alpha, and ERP Response Selectivity. Frontiers in Human Neuroscience 4.score: 870.1
    The specificity of neural responses to visual objects is a major topic in visual neuroscience. In humans, functional magnetic resonance imaging (fMRI) studies have identified several regions of the occipital and temporal lobe that appear specific to faces, letter-strings, scenes, or tools. Direct electrophysiological recordings in the visual cortical areas of epileptic patients have largely confirmed this modular organization, using either single-neuron peri-stimulus time-histogram or intracerebral event-related potentials (iERP). In parallel, a new research stream has emerged using high-frequency gamma-band activity (...)

    Adrian G. Guggisberg, Sarang S. Dalal, Armin Schnider & Srikantan S. Nagarajan (2011). The Neural Basis of Event-Time Introspection. Consciousness and Cognition 20 (4):1899-1915.score: 870.0
    We explored the neural mechanisms allowing humans to report the subjective onset times of conscious events. Magnetoencephalographic recordings of neural oscillations were obtained while human subjects introspected the timing of sensory, intentional, and motor events during a forced choice task. Brain activity was reconstructed with high spatio-temporal resolution. Event-time introspection was associated with specific neural activity at the time of subjective event onset which was spatially distinct from activity induced by the event itself. Different brain regions were selectively recruited for (...)

    Neil Dalal (forthcoming). Contemplative Grammars: Śaṅkara's Distinction of Upāsana and Nididhyāsana. Journal of Indian Philosophy:1-28.score: 420.1
    Śaṅkara’s Advaita Vedānta is largely dismissive of ritual action, in part because the metaphysical position of non-duality erodes any independent existence of the individual as a ritual agent, and because knowledge of non-duality is thought to be independent of action. However, a close reading of Śaṅkara shows that he does accept forms of devotional practice that have remained largely marginalized in studies of Advaita Vedānta. This article compares and contrasts contemplative devotion, in the form of visualized meditations (upāsanas) on īśvara, (...)

    [deleted]A. G. Guggisberg, S. S. Dalal, A. M. Findlay & S. S. Nagarajan (2006). High-Frequency Oscillations in Distributed Neural Networks Reveal the Dynamics of Human Decision Making. Frontiers in Human Neuroscience 1:14-14.score: 240.0
    We examine the relative timing of numerous brain regions involved in human decisions that are based on external criteria, learned information, personal preferences, or unconstrained internal considerations. Using magnetoencephalography (MEG) and advanced signal analysis techniques, we were able to non-invasively reconstruct oscillations of distributed neural networks in the high-gamma frequency band (60–150 Hz). The time course of the observed neural activity suggested that two-alternative forced choice tasks are processed in four overlapping stages: processing of sensory input, option evaluation, intention formation, (...)
