Gap junction plasticity can lead to spindle oscillations [PDF]
arXiv, 2017 Patterns of waxing and waning oscillations, called spindles, are observed in multiple brain regions during sleep. Spindle are thought to be involved in memory consolidation. The origin of spindle oscillations is ongoing work but experimental results point towards the thalamic reticular nucleus (TRN) as a likely candidate.

Using synchrosqueezing transform to discover breathing dynamics from ECG signals [PDF]
arXiv, 2011 The acquisition of breathing dynamics without directly recording the respiratory signals is beneficial in many clinical settings. The electrocardiography (ECG)-derived respiration (EDR) algorithm enables data acquisition in this manner. However, the EDR algorithm fails in analyzing such data for patients with atrial fibrillation (AF) because of their ...

Nursing Open, Volume 10, Issue 2, Page 469-478, February 2023., 2023 Abstract Aim One of the challenges of robotic‐assisted surgery is related to positioning of the patient on the operating table. Technological developments place increased demands on operating room nurses' competence to prevent positioning injuries and ensuring care quality.

Using Branch Predictors to Monitor Brain Activity [PDF]
arXiv, 2017 A key problem with neuroprostheses and brain monitoring interfaces is that they need extreme energy efficiency. One way of lowering energy is to use the low power modes avail- able on the processors embedded in these devices. We present a technique to predict when neuronal activity of interest is likely to occur, so that the processor can run at ...

Fisher-Rao Regularized Transport Analysis of the Glymphatic System and Waste Drainage [PDF]
arXiv, 2019 In this work, a unified representation of all the time-varying dynamics is accomplished with a Lagrangian framework for analyzing Fisher-Rao regularized dynamical optimal mass transport (OMT) derived flows. While formally equivalent to the Eulerian based Schr\"odinger bridge OMT regularization scheme, the Fisher-Rao approach allows a simple and ...

Neuropsychopharmacology Reports, Volume 42, Issue 4, Page 492-501, December 2022., 2022 Abstract Aim We previously reported that oxytocin, a peptide hormone, can reverse the β‐amyloid peptide (25–35) (Aβ25–35)‐induced impairments of the murine hippocampal synaptic plasticity. In this study, we examined the effects of oxytocin on the Aβ25–35‐induced impairment of cognitive behavior in murine in order to investigate the potential of ...

Limited but consistent gains in adversarial robustness by co-training object recognition models with human EEG [PDF]
arXivIn contrast to human vision, artificial neural networks (ANNs) remain relatively susceptible to adversarial attacks. To address this vulnerability, efforts have been made to transfer inductive bias from human brains to ANNs, often by training the ANN representations to match their biological counterparts. Previous works relied on brain data acquired in

Optimisation and validation of a co‐manipulated robot for brachytherapy procedure
The International Journal of Medical Robotics and Computer Assisted Surgery, Volume 19, Issue 1, February 2023., 2023 Abstract Background Low‐dose rate brachytherapy is the referent treatment for early‐stage prostate cancer and consists in manually inserting radioactive seeds within the organ to destroy tumorous cells. This treatment is inaccurate leading to side effects. Researchers developed robots to improve this technique.
