Episodic Memory Involves Transient And Sparse Connectivity Aligned To Both Internal And External Events, Adam J. O. Dede, Peter Brunner, Jarod L. Roland, Et Al.

2020-Current year OA Pubs

Episodic memory depends on the coordination of local processing, indexed by high-frequency broadband (HFB) activity, with global organization, indexed by theta oscillations. However, theta and HFB exhibit asynchronous timing, raising the question of how results of local processing are communicated. Using intracranial EEG in patients performing a recognition memory task, we examined this coordination across medial temporal (MTL) and prefrontal (PFC) regions. HFB peaks occurred earlier in the MTL than in the PFC. Contrasting analyses were anchored either to these internally driven HFB peaks or to the external event of stimulus presentation. We discovered three key results. First, the role …

Understanding The Effects Of Real-Time Head Position Feedback On Postural Sway In Terms Of Changes In Underlying Deterministic And Stochastic Dynamical Processes, Steven J. Harrison, Benjamin De Bari, Ryan Poutre, Jeffrey M. Kinsella-Shaw

College of Humanities and Sciences Faculty Papers

Our perceptual systems detect information about how our body is moving relative to the surrounding environment. Such information is essential to our ability to maintain upright standing balance. Real-time postural feedback systems are technologies that appear to enhance our ability to detect information about the movements of our body, and as a consequence improve our capacity to control the posture of our body. Here we examine a system in which real-time measurements of head position were "felt" as changes in the intensity of vibration of tactors in a headband. Using this system, participants were able to stabilize their body posture, …

Stereoelectroencephalography Reveals Neural Signatures Of Multisensory Integration In The Human Superior Temporal Sulcus During Audiovisual Speech Perception, Yue Zhang, John F Magnotti, Xiang Zhang, Zhengjia Wang, Yingjia Yu, Kathryn A Davis, Sameer A Sheth, H Isaac Chen, Daniel Yoshor, Michael S Beauchamp

Faculty, Staff and Students Publications

Human speech perception is multisensory, integrating auditory information from the talker's voice with visual information from the talker's face. BOLD fMRI studies have implicated the superior temporal gyrus (STG) in processing auditory speech and the superior temporal sulcus (STS) in integrating auditory and visual speech, but as an indirect hemodynamic measure, fMRI is limited in its ability to track the rapid neural computations underlying speech perception. Using stereoelectroencephalography (sEEG) electrodes, we directly recorded from the STG and STS in 42 epilepsy patients (25F, 17M). Participants identified single words presented in auditory, visual, and audiovisual formats with and without added auditory …

When operating on gliomas near critical language regions, surgeons risk either leaving residual tumor or inducing permanent postoperative language deficits (PLDs). Despite the advent of intraoperative mapping techniques, subjective judgments frequently determine important surgical decisions. We aim to inform data-driven surgery by constructing a non-invasive mapping approach that quantitatively predicts the impact of individual surgical decisions on long-term language function. This study included 79 consecutive patients undergoing resection of language-eloquent gliomas. Patients underwent preoperative navigated transcranial magnetic stimulation (TMS) language mapping to identify language-positive sites ("TMS points") and their associated white matter tracts ("TMS tracts") as well as formal language …

Effect Of Age On Isth-Bat Scores And Low Vwf Diagnosis In The Zimmerman Program, Ferdows Atiq, Jorge Di Paola, Et Al.

2020-Current year OA Pubs

An essential component of low von Willebrand factor (VWF)/type 1 von Willebrand disease (VWD) diagnosis is to identify patients with an increased bleeding phenotype, as most individuals with VWF levels in the 30 to 50 IU/dL range do not bleed. The International Society on Thrombosis and Haemostasis-bleeding assessment tool (ISTH-BAT), widely used for assessing bleeding severity, has recently been shown to be age dependent. Although age may also influence ISTH-BAT scores in individuals with VWF levels between 30 and 50 IU/dL, and subsequently affect low VWF diagnosis, this relationship has not been investigated. Therefore, we analyzed 325 participants from the …

Transfer Learning Via Distributed Brain Recordings Enables Reliable Speech Decoding, Aditya Singh, Tessy Thomas, Jinlong Li, Greg Hickok, Xaq Pitkow, Nitin Tandon

Faculty, Staff and Student Publications

Speech brain-computer interfaces (BCIs) combine neural recordings with large language models to achieve real-time intelligible speech. However, these decoders rely on dense, intact cortical coverage and are challenging to scale across individuals with heterogeneous brain organization. To derive scalable transfer learning strategies for neural speech decoding, we used minimally invasive stereo-electroencephalography recordings in a large cohort performing a demanding speech motor task. A sequence-to-sequence model enabled decoding of variable-length phonemic sequences prior to and during articulation. This enabled development of a cross-subject transfer learning framework to isolate shared latent manifolds while enabling individual model initialization. The group-derived decoder significantly outperformed …
