Bogunovic, Hrvoje (Date of defense: 2012-09-28)

Los derrames cerebrales son una de las causas principales de morbilidad y mortalidad en los países desarrollados. Esto ha motivado una búsqueda de configuraciones del sistema vascular que se cree que están asociadas con ...

Geometrical room acoustics: ray based simulation for room acoustics

Durany Vendrell, Jaume (Date of defense: 2016-09-14)

L’acústica de sales és la ciència encarregada d’estudiar la propagació del so en entorns tancats. La informació acústica de qualsevol entorn, coneguda com la resposta impulsional, s’expressa en termes del camp acústic ...

Giving centre stage to top-down inhibitory mechanisms for selective attention

Low, Sock Ching (Date of defense: 2020-12-15)

Selective attention determines the sensory signals that are processed at higher levels at the expense of others and is biased by higher-order brain regions which anticipate task-relevant stimuli and increase neural sensitivity ...

Grounding body ownership and language in action: evidence from healthy and damaged brains

Grechuta, Klaudia (Date of defense: 2019-07-05)

Contrary to the classical theory of mind, largely inspired by dualism, the theoretical framework of embodiment emphasizes the constitutive role of the body in the process of cognition. This view also referred to as the ...

Grounding brain mechanisms in the spatiotemporal properties of cerebral and behavioral networks

Ulysse, Laura (Date of defense: 2022-11-04)

The spatiotemporal properties of the cerebral and behavioral networks are key elements to understand normal brain functioning and their breakdowns. This dissertation focuses on the cerebral networks of the brain regions’ ...

Hemodynamic modeling of cerebral aneurysms

Geers, Adrianus Johannes (Date of defense: 2015-01-12)

Cerebral aneurysms are localized, pathological dilatations of cerebral arteries. Their rupture causes a subarachnoid hemorrhage and is associated with high rates of morbidity and mortality. Over the last decade, the ...

How do infants represent others?: biases towards native language and rational agents

Colomer Canyelles, Marc (Date of defense: 2019-10-02)

Much of the information infants acquire they learn it by observing and interacting with others. However, not all individuals provide information that is functionally and/or culturally relevant. Infants’ capacity of identifying ...

Human-centered learning design with technology

Garreta Domingo, Muriel (Date of defense: 2018-07-25)

To improve and innovate education, a novel conception of the role of design in this realm is needed. Human-centered design (HCD), a problem-solving framework underpinned by the user perspective in all stages of the ...

Human-centered machine learning for music emotion recognition

Gómez Cañón, Juan sebastián (Date of defense: 2022-10-26)
