Dynamic rewiring of electrophysiological brain networks during learning

open access: yesNetwork Neuroscience, 2023
Human learning is an active and complex process. However, the brain mechanisms underlying human skill learning and the effect of learning on the communication between brain regions, at different frequency bands, are still largely unknown.

Gastrointestinal symptoms and disorders related to COVID-19. Lessons learned from gastroenterologists

open access: yesRevista Médica del Hospital General de México, 2022
COVID-19 is mainly a respiratory illness caused by the SARS-CoV-2 but can also lead to GI symptoms. The primary host receptor which mediates the mechanism as SARS-CoV-2 enters the cell is the ACE2 receptor.

Attentional capture during attentional awakening [PDF]

open access: yesAttention, Perception, & Psychophysics, 2015
We investigated whether attentional set is available at the beginning of a trial or whether it develops gradually within a trial. Thus, we manipulated the time from the onset of a trial to a target and observers' search strategy. We also observed the effect of the presence or absence of distractors as an index of the temporal development of attentional

The field of expertise modulates the time course of neural processes associated with inhibitory control in a sport decision-making task

open access: yesScientific Reports, 2022
Inhibitory control (IC), the ability to suppress inappropriate actions, can be improved by regularly facing complex and dynamic situations requiring flexible behaviors, such as in the context of intensive sport practice.

Revisiting previously searched locations in visual neglect: role of right parietal and frontal lesions in misjudging old locations as new [PDF]

open access: yes, 2005
Right-hemisphere patients with left neglect often demonstrate abnormal visual search, re-examining stimuli to the right while ignoring those to the left.

A Call for the Empirical Investigation of Tear Stimuli

open access: yesFrontiers in Psychology, 2020
Emotional crying is a uniquely human behavior, which typically elicits helping and empathic responses from observers. However, tears can also be used to deceive.

How one block of trials influences the next: persistent effects of disease prevalence and feedback on decisions about images of skin lesions in a large online study

open access: yesCognitive Research, 2022
Using an online, medical image labeling app, 803 individuals rated images of skin lesions as either "melanoma" (skin cancer) or "nevus" (a skin mole). Each block consisted of 80 images.

Spontaneous activity in the waiting brain: A marker of impulsive choice in attention-deficit/hyperactivity disorder?

open access: yesDevelopmental Cognitive Neuroscience, 2015
Background: Spontaneous very low frequency oscillations (VLFO), seen in the resting brain, are attenuated when individuals are working on attention demanding tasks or waiting for rewards (Hsu et al., 2013).
