Neural correlates of memory impairment and rescue in a mouse model of Down syndrome
Understanding the neural correlates of intellectual disability is still a central and unresolved problem in neuroscience. Here we have unravelled several candidate neural substrates of memory impairment and rescue using a ...
Neural correlates of word learning and meaning acquisition
The series of studies that comprise this dissertation are aimed at simulating vocabulary learning and meaning acquisition of different types of words, namely words which differ in imageability. For this purpose, the human ...
Neural efficiency of a specific cognitive training in working memory in multiple sclerosis patients
Multiple sclerosis is an autoimmune degenerative disease that produces cognitive impairment secondary to white and gray matter disruption of the central nervous system. The main objectives of this doctoral thesis were: ...
Neural entrainment to languages of different rhythms in adults and infants
In this thesis, we explored neural entrainment as a potential mechanism to underline the behavioral evidence that certain phonological properties of listeners’ native language affects speech segmentation. In two experimental ...
Neural Information Extraction from Semi-structured Documents
Sectors com la informació i tecnologia d'assegurances, finances i legal, processen un continu de factures, justificants, reclamacions o similar diàriament. L'èxit en l'automatització d'aquestes transaccions es basa en ...
Neural inhibitory mechanisms regulating colonic mechanical activity: role of adenosine triphosphate, nitric oxide and hydrogen sulphide
La neurotransmissió inhibitòria participa en el control de l’activitat motora del còlon. Els neurotransmissors inhibitoris hiperpolaritzen la membrana del múscul llis, generant un potencial d'unió inhibitori (”Inhibitory ...
Neural machine translation evaluation & error analysis in a Spanish-Korean translation
From RBMT to SMT and NMT, the MT field witnessed, first, a conceptual turn —from rule-based to data-base— and now, a technological turn —from MT algorithm to ML algorithm. Now that NMT became a new state of the art, this ...
Neural map organization and development in the lateral-line system
Les neurones sensorials projecten al sistema nerviós central seguint una distribució espacial ordenada, formant mapes neuronals que representen propietats dels estímuls sensorials i que són considerats essencials per a ...
Neural mechanisms of abstract rule changes in speech : exploring phonologic and attentional constraints
L’extracció de regles de la parla és crucial per a l’adquisició del llenguatge. La present dissertació estudia el mecanisme d’aprenentatge de regles explorant com el cervell detecta regularitats rellevants dins del senyal ...
Neural mechanisms of willingness to fight and die for sacred values in the context of intercultural conflict
Los conflictos interculturales a menudo se propagan y se mantienen en base a una defensa apasionada de puntos de vista opuestos, tanto de tipo religioso como nacionalista, por parte de miembros de una comunidad moral ...
Neural network mechanisms of working memory interference
Our ability to memorize is at the core of our cognitive abilities. How could we effectively make decisions without considering memories of previous experiences? Broadly, our memories can be divided in two categories: ...
Neural networks connecting emotion and cognition assessed in psychopaths, cocaine users and obsessive-compulsive disorder using MRI
Emotional processing is fundamental for normal socialization, interpersonal interactions, successful decision-making and overall to self-regulate behavior according to each context. Adequate emotional processing relies ...
Neural networks for singing voice extraction in monaural polyphonic music signals
This thesis dissertation focuses on singing voice extraction from polyphonic musical signals. In particular, we focus on two cases; contemporary popular music, which typically has a processed singing voice with instrumental ...
Neural signatures of semantic anticipation in sentence comprehension
It has been proposed that the human brain is a proactive processor. Rather than passively receiving information, it is seen as continuously attempting to predict what will happen next. In the domain of language, ...
Neural signatures of word learning in adults and children: a multi-methodological approach
Language is one of the main traits of humans. Language is used to transmit information about thoughts, knowledge, and feelings in a very flexible way. Since childhood, humans show an innate ability to acquire language and ...
Neural Stem Cell Factors as Important Players in Glioblastoma Pathogenesis
The main goal of this PhD thesis was to understand the mechanisms underlying GBM tumor formation and progression, with a special emphasis on the study of factors that have a role in normal NSC biology, which might be ...
Neural stochastic dynamics of perceptual decision making
Models computacionals basats en xarxes a gran escala d'inspiració neurobiològica permeten descriure els correlats neurals de la decisió observats en certes àrees corticals com una transició entre atractors de la xarxa ...
Neural substrates of psychotic-like states and cognitive impairment in a mouse model of schizophrenia and subsequent rescue by antipsychotic drugs
Disruption of communication in brain circuits involving the prefrontal cortex (PFC) and the hippocampus (HPC) has been suggested to be a hallmark characteristic of schizophrenia. Therefore, a better understanding of the ...
Neuregulin reduces glycaemia by targeting liver metabolism
Neuregulin (NRG), which structurally belongs to an EGF family of growth factors, activated in acute manner signaling cascades that lead to changes in whole-body glucose metabolism in fasted mice. Besides previously observed ...
Neuroanatomical and neurofunctional brain basis of cognitive deficits in adolescent subjects who were born preterm. Structural and functional magnetic resonance study
The general aim of this thesis is to study the cerebral basis of cognitive disturbances in adolescents with history of premature birth (PB). As previous manual volumetric investigations in PB samples, we quantitatively ...
