Cognitive Deficits and Associated ERP N400 Abnormalities in FXTAS With Parkinsonism
2018
Objective: To examine cognitive deficits and associated brain activity in fragile X-associated tremor/ataxia syndrome (FXTAS) patients with parkinsonism (FXTp+), in relation to FXTAS patients without parkinsonism (FXTp-), and normal elderly controls (NC). Methods: Retrospective reviews were performed in 65 FXTAS patients who participated in the event-related brain potential (ERP) study and also had either a videotaped neurological examination or a neurological examination for extrapyramidal signs. Parkinsonism was defined as having bradykinesia with at least one of the following: rest tremor, postural instability, hypermyotonia, or rigidity. Eleven FXTp+ patients were identified and compare…
How Literacy Shapes Orthographic Processing
2022
La lectura es una habilidad indispensable en nuestra sociedad. Sin ella, no podríamos acceder a la historia, o aprender de nuestros avances y retrocesos. Resulta casi milagroso que el Homo sapiens hiciera unas marcas en una piedra para aumentar drásticamente su capacidad de memoria. Estas marcas en la piedra, que serían lo que ahora llamamos letras, se convirtieron en herramientas. Herramientas que alteran la maquinaria cerebral para conectar las formas visuales con un significado, es decir, para sustentar la lectura. Hoy en día, la lectura es parte de nuestra vida cotidiana hasta tal punto que no nos damos cuenta de su complejidad. Cuando leemos, nuestros ojos saltan de palabra a palabra, …
Stroke Cognitive Medical Assistant (StrokeCMA)
2018
Stroke is the number two killer after heart disease since it is responsible for almost 10% of all deaths worldwide. The main problem with a stroke is a significant delay in treatment that happened mainly due to inappropriate detection of stroke symptoms or inability of a person to perform further necessary actions, and might cause death, permanent disabilities, as well as more expensive treatment and rehabilitation. Nowadays assessment of a stroke is done by human, following widely adopted FAST approach of stroke assessment. Since a human factor become one of the causes of treatment delay, offered solution will try to minimize this factor. Artificial Intelligence, Cognitive Computing, Machi…
The Contribution of Event-Related Potentials to the Understanding of Sign Language Processing and Production in the Brain : Experimental Evidence and…
2022
Functional neuroimaging allows investigation of the timing properties of the brain mechanisms underlying covert language processing. This paper presents a review of the use of the neuroimaging technique called Event-Related Potentials (ERPs) in sign language (SL) research. In the field of neurolinguistics, ERPs have been widely used in the study of spoken language, but their use in SL is still rare. Studying the neurocognitive aspects of SL could lead to a better understanding of the specific processing of SL in the brain. This review outlines the basic theoretical and methodological principles of ERPs. We focus on three groups of ERPs that are particularly relevant to SL processing and pro…
BALANCE PROPERTIES AND DISTRIBUTION OF SQUARES IN CIRCULAR WORDS
2010
We study balance properties of circular words over alphabets of size greater than two. We give some new characterizations of balanced words connected to the Kawasaki-Ising model and to the notion of derivative of a word. Moreover we consider two different generalizations of the notion of balance, and we find some relations between them. Some of our results can be generalized to non periodic infinite words as well.

Shift-Invariant Canonical Polyadic Decomposition of Complex-Valued Multi-Subject fMRI Data with a Phase Sparsity Constraint
2020
Canonical polyadic decomposition (CPD) of multi-subject complex-valued fMRI data can be used to provide spatially and temporally shared components among groups with both magnitude and phase information. However, the CPD model is not well formulated due to the large subject variability in the spatial and temporal modalities, as well as the high noise level in complex-valued fMRI data. Considering that the shift-invariant CPD can model temporal variability across subjects, we propose to further impose a phase sparsity constraint on the shared spatial maps to denoise the complex-valued components and to model the inter-subject spatial variability as well. More precisely, subject-specific time …
Waste Usage as Secondary Resource
2021
The current state of waste management in Poltava region is summarized in this article. In this article were determined places of accumulation and the influence of population size on the volumes of domestic solid wastes formation. Here also was analyzed dynamics of changes in the production of domestic solid wastes in rural areas and in cities. The morphological composition of domestic solid wastes was determined due to researches during 2017-2019. In the article was conducted comparative analysis of the data of changes in the percentage of components, which are part of domestic solid wastes depending on the time of year. It is determined that about 55% of the waste is the organic part of do…
A dynamic adjustment model of saccade lengths in reading for word-spaced orthographies : evidence from simulations and invisible boundary experiments
2021
Contemporary models of eye movement control in reading assume a discrete target word selection process preceding saccade length computation, while the selection itself is assumed to be driven by word identification processes. However, a potentially more parsimonious, dynamic adjustment view allows both next word length and its content (e.g. orthographic) to modulate saccade length in a continuous manner. Based on a recently proposed center-based saccade length account (a new regression model of forward saccade length is introduced and validated in a simulation study. Further, additional simulations and gaze-contingent invisible boundary experiments were used to study the cognitive mechanism…
