    The neural basis of event-time introspection.Adrian G. Guggisberg, Sarang S. Dalal, Armin Schnider & Srikantan S. Nagarajan - 2011 - Consciousness and Cognition 20 (4):1899-1915.
    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 (...)

Owen, Coleman Garrett, Danielle Mizuiri, Pratik Mukherjee, Srikantan S. Nagarajan & Steven W. Cheung - 2018 - Frontiers in Human Neuroscience 12:410138.
    Single-sided deafness (SSD) or profound unilateral hearing loss obligates the only serviceable ear to capture all acoustic information. This loss of binaural function taxes cognitive resources for accurate listening performance, especially under adverse environments or challenging tasks. We hypothesized that adults with SSD would manifest both functional and structural brain plasticity compared to controls with normal binaural hearing. We evaluated functional alterations using magnetoencephalographic imaging (MEGI) of brain activation during performance of a moderately difficult auditory syllable sequence reproduction task and (...)

    Clinical Validation of the Champagne Algorithm for Epilepsy Spike Localization.Chang Cai, Jessie Chen, Anne M. Findlay, Danielle Mizuiri, Kensuke Sekihara, Heidi E. Kirsch & Srikantan S. Nagarajan - 2021 - Frontiers in Human Neuroscience 15.
    Magnetoencephalography is increasingly used for presurgical planning in people with medically refractory focal epilepsy. Localization of interictal epileptiform activity, a surrogate for the seizure onset zone whose removal may prevent seizures, is challenging and depends on the use of multiple complementary techniques. Accurate and reliable localization of epileptiform activity from spontaneous MEG data has been an elusive goal. One approach toward this goal is to use a novel Bayesian inference algorithm—the Champagne algorithm with noise learning—which has shown tremendous success in (...)

    Auditory Verb Generation Performance Patterns Dissociate Variants of Primary Progressive Aphasia.Sladjana Lukic, Abigail E. Licata, Elizabeth Weis, Rian Bogley, Buddhika Ratnasiri, Ariane E. Welch, Leighton B. N. Hinkley, Z. Miller, Adolfo M. Garcia, John F. Houde, Srikantan S. Nagarajan, Maria Luisa Gorno-Tempini & Valentina Borghesani - 2022 - Frontiers in Psychology 13.
    Primary progressive aphasia is a clinical syndrome in which patients progressively lose speech and language abilities. Three variants are recognized: logopenic, associated with phonology and/or short-term verbal memory deficits accompanied by left temporo-parietal atrophy; semantic, associated with semantic deficits and anterior temporal lobe atrophy; non-fluent associated with grammar and/or speech-motor deficits and inferior frontal gyrus atrophy. Here, we set out to investigate whether the three variants of PPA can be dissociated based on error patterns in a single language task. We (...)
