Functional reorganization of memory processing in the hippocampus is associated with neuroprotector GLP-1 levels in type 2 diabetes
Autor: Nádia S. Canário, Joana Crisóstomo, Carolina Moreno, João V. Duarte, Isabel C. Duarte, Mário J. Ribeiro, Beatriz Caramelo, Leonor V. Gomes, Paulo Matafome, Francisco P. Oliveira, Miguel Castelo-Branco
Publikováno v: Heliyon, Vol 10, Iss 6, Pp e27412- (2024)
Type 2 diabetes (T2D) often impairs memory functions, suggesting specific vulnerability of the hippocampus. In vivo neuroimaging studies relating encoding and retrieval of memory information with endogenous neuroprotection are lacking. The neuroprote

A neural network underlying cognitive strategies related to eating, weight and body image concerns
Autor: Cristiana C. Marques, Alexandre Sayal, Joana Crisóstomo, João V. Duarte, Paula Castilho, Kenneth Goss, Ana T. Pereira, Miguel Castelo-Branco
Publikováno v: Frontiers in Human Neuroscience, Vol 17 (2024)
Concerns about food intake, weight and body shape can trigger negatively loaded emotions, which may prompt the use of cognitive strategies to regulate these emotional states. A novel fMRI task was developed to assess the neurobehavioral correlates of

A human cortical adaptive mutual inhibition circuit underlying competition for perceptual decision and repetition suppression reversal
Autor: Teresa Sousa, Alexandre Sayal, João V. Duarte, Gabriel N. Costa, Miguel Castelo-Branco
Publikováno v: NeuroImage, Vol 285, Iss , Pp 120488- (2024)
A model based on inhibitory coupling has been proposed to explain perceptual oscillations. This 'adapting reciprocal inhibition' model postulates that it is the strength of inhibitory coupling that determines the fate of competition between percepts.

The hemodynamic response function as a type 2 diabetes biomarker: a data-driven approach
Autor: Pedro Guimarães, Pedro Serranho, João V. Duarte, Joana Crisóstomo, Carolina Moreno, Leonor Gomes, Rui Bernardes, Miguel Castelo-Branco
Publikováno v: Frontiers in Neuroinformatics, Vol 17 (2024)
IntroductionThere is a need to better understand the neurophysiological changes associated with early brain dysfunction in Type 2 diabetes mellitus (T2DM) before vascular or structural lesions. Our aim was to use a novel unbiased data-driven approach

The role of early functional neuroimaging in predicting neurodevelopmental outcomes in neonatal encephalopathy
Autor: Carla R. Pinto, João V. Duarte, Carla Marques, Inês N. Vicente, Catarina Paiva, João Éloi, Daniela J. Pereira, Bárbara R. Correia, Miguel Castelo-Branco, Guiomar Oliveira
Publikováno v: European Journal of Pediatrics. 182:1191-1200
Reliably assessing the early neurodevelopmental outcomes in infants with neonatal encephalopathy (NE) is of utmost importance to advise parents and implement early and personalized interventions. We aimed to evaluate the accuracy of neuroimaging moda

Identification of competing neural mechanisms underlying positive and negative perceptual hysteresis in the human visual system

Publikováno v: NeuroImage, Vol 221, Iss , Pp 117153- (2020)
Hysteresis is a well-known phenomenon in physics that relates changes in a system with its prior history. It is also part of human visual experience (perceptual hysteresis), and two different neural mechanisms might explain it: persistence (a cause o

Neuroimaging studies have suggested that hMT+ encodes global motion interpretation, but this contradicts the notion that BOLD activity mainly reflects neuronal input. While measuring fMRI responses at 7 Tesla, we used an ambiguous moving stimulus, yi

A novel morphometric signature of brain alterations in type 2 diabetes: Patterns of changed cortical gyrification
Autor: Carolina Moreno, Leonor Gomes, Miguel Castelo-Branco, João V. Duarte, Joana Crisóstomo
Publikováno v: The European journal of neuroscience. 54(6)
Type 2 diabetes is a chronic disease that creates atrophic signatures in the brain, including decreases of total and regional volume of grey matter, white matter, and cortical thickness. However, there is a lack of studies assessing cortical gyrifica

Optimizing EEG source reconstruction with concurrent fMRI-derived spatial priors
Autor: João V. Duarte, Rodolfo Abreu, Ana Lima, Júlia F. Soares, Sónia Batista, Lívia Sousa, Miguel Castelo-Branco
Reconstructing EEG sources involves a complex pipeline, with the inverse problem being the most challenging. Multiple inversion algorithms are being continuously developed, aiming to tackle the non-uniqueness of this problem, which has been shown to
