The effects of white matter hyperintensities on MEG power spectra in population with mild cognitive impairment

open access: yesFrontiers in Human Neuroscience, 2023
Cerebrovascular disease is responsible for up to 20% of cases of dementia worldwide, but also it is a major comorbid contributor to the progression of other neurodegenerative diseases, like Alzheimer’s disease. White matter hyperintensities (WMH) are the

Age and APOE genotype affect the relationship between objectively measured physical activity and power in the alpha band, a marker of brain disease

open access: yesAlzheimer’s Research & Therapy, 2020
Background Electrophysiological studies show that reductions in power within the alpha band are associated with the Alzheimer’s disease (AD) continuum. Physical activity (PA) is a protective factor that has proved to reduce AD risk and pathological brain

How Sequential Interactive Processing Within Frontostriatal Loops Supports a Continuum of Habitual to Controlled Processing

open access: yesFrontiers in Psychology, 2020
We address the distinction between habitual/automatic vs. goal-directed/controlled behavior, from the perspective of a computational model of the frontostriatal loops.

Understanding the effects of cortical gyrification in tACS: insights from experiments and computational models

open access: yesFrontiers in Neuroscience, 2023
The alpha rhythm is often associated with relaxed wakefulness or idling and is altered by various factors. Abnormalities in the alpha rhythm have been linked to several neurological and psychiatric disorders, including Alzheimer's disease.

Computer use in cognitive psychology [PDF]

open access: yesBehavior Research Methods, Instruments, & Computers, 1994
Some influences of computers on theory and methodology in cognitive research are discussed. Theoretical constructs that cognitive science has borrowed from computer science include processing algorithms, processing rates, information organization, and information selection.

Neuroimaging evidence for a network sampling theory of individual differences in human intelligence test performance

open access: yesNature Communications, 2021
A defining human characteristic is the ability to perform diverse cognitively challenging tasks. The authors show that this adaptability relates to a network sampling mechanism, where brain-wide network states transiently blend the unique combinations of

Recording site placement on planar silicon-based probes affects signal quality in acute neuronal recordings

open access: yesScientific Reports, 2021
Multisite, silicon-based probes are widely used tools to record the electrical activity of neuronal populations. Several physical features of these devices are designed to improve their recording performance. Here, our goal was to investigate whether the

Demonstration experiments in perception and cognitive psychology for the Macintosh computer [PDF]

open access: yesBehavior Research Methods, Instruments, & Computers, 1987
A package of programs demonstrating psychology experiments widely cited in perception and cognitive psychology textbooks is described. The programs are suitable for laboratory research projects and in-class demonstrations. An attractive feature of the programs is that they have provisions for changing experimental parameters to allow students to design

Variational Bayesian Parameter Estimation Techniques for the General Linear Model

open access: yesFrontiers in Neuroscience, 2017
Variational Bayes (VB), variational maximum likelihood (VML), restricted maximum likelihood (ReML), and maximum likelihood (ML) are cornerstone parametric statistical estimation techniques in the analysis of functional neuroimaging data.

A multi-expert ensemble system for predicting Alzheimer transition using clinical features

open access: yesBrain Informatics, 2022
Alzheimer’s disease (AD) diagnosis often requires invasive examinations (e.g., liquor analyses), expensive tools (e.g., brain imaging) and highly specialized personnel.
