Distinct oscillatory patterns differentiate between segregation and integration...
Costa, Gabriel Nascimento; Schaum, Michael; Duarte, João Valente; Martins, Ricardo; Duarte, Isabel Catarina; Castelhano, João; Wibral, MichaelRecently, there has been a resurgence in experimental and conceptual efforts to understand how brain rhythms can serve to organize visual information. Oscillations can provide temporal structure for neuronal processing and form a basis for integrating information across brain areas. Here, we use a bistable paradigm and a data-driven approach to test the hypothesis that oscillatory modulations associate with the...
Mental health and post-traumatic stress disorder in firefighters: an integrated...
Oliveira, Joana; Aires Dias, Joana; Duarte, Isabel Catarina; Caldeira, Salomé; Marques, António Reis; Rodrigues, Vítor; Redondo, JoãoIntroduction: The presence of post-traumatic stress disorder (PTSD) symptomatology in firefighters is an ever-pressing issue that requires close attention for adequate interventions. The present study investigated PTSD and global psychopathology prevalence in a sample of highly risk-exposed Portuguese firefighters, collected after the widespread deadly wildfires in 2017 that ravaged the country. Following an ac...
A 3D-Printed Ceramics Innovative Firing Technique: A Numerical and Experimental...
Santos, Tiago; Ramani, Melinda; Devesa, Susana; Batista, Catarina; Franco, Margarida; Duarte, Isabel Catarina; Costa, Luís; Ferreira, NelsonAdditive manufacturing (AM), also known as three-dimensional (3D) printing, allows the fabrication of complex parts, which are impossible or very expensive to produce using traditional processes. That is the case for dinnerware and artworks (stoneware, porcelain and clay-based products). After the piece is formed, the greenware is fired at high temperatures so that these pieces gain its mechanical strength and ...
Parahippocampal deactivation and hyperactivation of central executive, saliency...
Mouga, Susana; Duarte, Isabel Catarina; Café, Cátia; Sousa, Daniela; Duque, Frederico; Oliveira, Guiomar; Castelo-Branco, MiguelThe concomitant role of the Central Executive, the Saliency and the Social Cognition networks in autism spectrum disorder (ASD) in demanding ecological tasks remains unanswered. We addressed this question using a novel task-based fMRI virtual-reality task mimicking a challenging daily-life chore that may present some difficulties to individuals with ASD: the EcoSupermarketX.; This research was supported by the ...
The Role of Continuous Theta Burst TMS in the Neurorehabilitation of Subacute S...
Dionísio, Ana; Gouveia, Rita; Castelhano, João; Duarte, Isabel Catarina; Santo, Gustavo C.; Sargento-Freitas, João; Duecker, FelixObjectives: Transcranial magnetic stimulation, in particular continuous theta burst (cTBS), has been proposed for stroke rehabilitation, based on the concept that inhibition of the healthy hemisphere helps promote the recovery of the lesioned one. We aimed to study its effects on cortical excitability, oscillatory patterns, and motor function, the main aim being to identify potentially beneficial neurophysiolog...
Attentional Cueing and Executive Deficits Revealed by a Virtual Supermarket Tas...
Mouga, Susana; Duarte, Isabel Catarina; Café, Cátia; Sousa, Daniela; Duque, Frederico; Oliveira, Guiomar; Castelo-Branco, MiguelExecutive functioning (EF) impairments in Autism Spectrum Disorder (ASD) impact on complex functions, such as social cognition. We assessed this link between EF, attentional cueing, and social cognition with a novel ecological task, "EcoSupermarketX." Our task had three blocks of increasing executive load and incorporated social and non-social cues, with different degrees of saliency. Performance of ASD and typ...
Ventral Caudate and Anterior Insula Recruitment During Value Estimation of Pass...
Duarte, Isabel Catarina; Coelho, Gonçalo; Brito-Costa, Sónia; Cayolla, Ricardo; Afonso, Sónia; Castelo-Branco, Miguel"Wanting", a component of reward processing, is a motivational property that guides decision making in goal-oriented behavior. This includes behavior aiming at supporting relational bonds, even at the group level. Accordingly, group belongingness works as this motivational property, which is fundamentally different from romantic or maternal love. While primary rewards (or learned associations, such as money) ha...
Mechanical, Thermal, and Acoustic Properties of Aluminum Foams Impregnated with...
Pinto, Susana C.; Marques, Paula A. A. P.; Vesenjak, Matej; Vicente, Romeu; Godinho, Luís; Krstulović-Opara, Lovre; Duarte, Isabel CatarinaHybrid structures with epoxy embedded in open-cell aluminum foam were developed by combining open-cell aluminum foam specimens with unreinforced and reinforced epoxy resin using graphene oxide. These new hybrid structures were fabricated by infiltrating an open-cell aluminum foam specimen with pure epoxy or mixtures of epoxy and graphene oxide, completely filling the pores. The e ects of graphene oxide on the m...
Evidence for impaired olfactory function and structural brain integrity in a di...
Ramos, João Nuno Pinto; Ribeiro, João Carlos; Pereira, Andreia Carvalho; Ferreira, Sónia; Duarte, Isabel Catarina; Castelo-Branco, MiguelDiseases involving cilia dysfunction, such as Usher Syndrome (USH), often involve visual and auditory loss. Psychophysical evidence has suggested that this may also hold true for the peripheral olfactory domain. Here we aimed to go a step further by attempting to establish relations between the integrity of cortical structures and olfactory function in this condition. We investigated olfactory function for USH ...
Impulsivity across reactive, proactive and cognitive domains in Parkinson's dis...
Canário, Nádia; Sousa, Mário; Moreira, Fradique; Duarte, Isabel Catarina; Oliveira, Francisco; Januário, Cristina; Castelo-Branco, MiguelImpulse control disorders (ICD) may occur in Parkinson's disease (PD) although it remains to be understood if such deficits may occur even in the absence of a formal ICD diagnosis. Moreover, studies addressing simultaneously distinct neurobehavioral domains, such as cognitive, proactive and reactive motor impulsivity, are still lacking. Here, we aimed to investigate if reactive, proactive and cognitive impulsiv...
