Investigating secondary white matter degeneration following ischemic stroke by modelling affected fiber tracts
Autor: Ivana Kancheva, Floor Buma, Gert Kwakkel, Angelina Kancheva, Nick Ramsey, Mathijs Raemaekers
Publikováno v: NeuroImage: Clinical, Vol 33, Iss , Pp 102945- (2022)
Secondary white matter degeneration is a common occurrence after ischemic stroke, as identified by Diffusion Tensor Imaging (DTI). However, despite recent advances, the time course of the process is not completely understood. The primary aim of this

Size of the spatial correlation between ECoG and fMRI activity
Autor: Giovanni Piantoni, Dora Hermes, Nick Ramsey, Natalia Petridou
Publikováno v: NeuroImage, Vol 242, Iss , Pp 118459- (2021)
Electrocorticography (ECoG) is typically employed to accurately identify the seizure focus as well as the location of brain functions to be spared during surgical resection in participants with drug-resistant epilepsy. Increasingly, this technique ha

Entropy bounds for multi-word perturbations of subshifts
Autor: NICK RAMSEY
Publikováno v: Ergodic Theory and Dynamical Systems. :1-9
Given a subshift $\Sigma $ of finite type and a finite set S of finite words, let $\Sigma \langle S\rangle $ denote the subshift of $\Sigma $ that avoids S. We establish a general criterion under which we can bound the entropy perturbation $h(\Sigma

Temporal Dynamics of Neural Responses in Human Visual Cortex
Autor: Iris I.A. Groen, Giovanni Piantoni, Stephanie Montenegro, Adeen Flinker, Sasha Devore, Orrin Devinsky, Werner Doyle, Patricia Dugan, Daniel Friedman, Nick Ramsey, Natalia Petridou, Jonathan Winawer
Publikováno v: J Neurosci
Neural responses to visual stimuli exhibit complex temporal dynamics, including sub-additive temporal summation, response reduction with repeated or sustained stimuli (adaptation), and slower dynamics at low contrast. These phenomena are often studie

Precise Spatial Tuning of Visually Driven Alpha Oscillations in Human Visual Cortex
Autor: Kenichi Yuasa, Iris I.A. Groen, Giovanni Piantoni, Stephanie Montenegro, Adeen Flinker, Sasha Devore, Orrin Devinsky, Werner Doyle, Patricia Dugan, Daniel Friedman, Nick Ramsey, Natalia Petridou, Jonathan Winawer
Neuronal oscillations at about 10 Hz, called alpha oscillations, are often thought to arise from synchronous activity across occipital cortex, reflecting general cognitive states such as arousal and alertness. However, there is also evidence that mod

Lattices over cyclic groups and Noether settings
Autor: Esther Beneish, Nick Ramsey
Publikováno v: Journal of Algebra. 452:212-226
For each positive integer m, let ω m be a primitive mth root of 1. Given a prime p, let a be an integer which is a primitive root of 1 mod p . Let I p , m be the ideal in Z [ ω m ] generated by p and ω m − a . Let G be a cyclic group of order n
