A probabilistic atlas of the human thalamic nuclei combining ex vivo MRI and histology
(NeuroImage, 2018)The human thalamus is a brain structure that comprises numerous, highly specific nuclei. Since these nuclei are known to have different functions and to be connected to different areas of the cerebral cortex, it is of great ... -
Accurate Bayesian segmentation of thalamic nuclei using diffusion MRI and an improved histological atlas
(ELSEVIER, 2023)The human thalamus is a highly connected brain structure, which is key for the control of numerous functions and is involved in several neurological disorders. Recently, neuroimaging studies have increasingly focused ... -
Automated Segmentation of the Human Hippocampus Along Its Longitudinal Axis
(Human Brain Mapping, 2016)The human hippocampal formation is a crucial brain structure for memory and cognitive function that is closely related to other subcortical and cortical brain regions. Recent neuroimaging studies have revealed differences ... -
Brain structure, phenotypic and genetic correlates of reading performance
(NATURE RESEARCH, 2023)Reading is an evolutionarily recent development that recruits and tunes brain circuitry connecting primary- and language-processing regions. We investigated whether metrics of the brain’s physical structure correlate with ... -
Connectivity of Frontoparietal Regions Reveals Executive Attention and Consciousness Interactions
(Cerebral Cortex, 2019)The executive control network is involved in the voluntary control of novel and complex situations. Solving conflict situations or detecting errors have demonstrated to impair conscious perception of near-threshold stimuli. ... -
Converging Evidence for Differential Specialization and Plasticity of Language Systems
(The Journal of Neuroscience, 2020)Functional specialization and plasticity are fundamental organizing principles of the brain. Since the mid-1800s, certain cognitive functions have been known to be lateralized, but the provenance and flexibility of ... -
Converging evidence for functional and structural segregation within the left ventral occipitotemporal cortex in reading
(Proceedings of the National Academy of Sciences of the United States of America (PNAS), 2018)The ventral occipitotemporal cortex (vOTC) is crucial for recognizing visual patterns, and previous evidence suggests that there may be different subregions within the vOTC involved in the rapid identification of word ... -
Disrupted salience network dynamics in Parkinson's disease patients with impulse control disorders
(Parkinsonism and Related Disorders, 2020)Background: Dynamic functional network analysis may add relevant information about the temporal nature of the neurocognitive alterations in PD patients with impulse control disorders (PD-ICD). Our aim was to investigate changes ... -
Encoding and inhibition of arbitrary episodic context with abstract concepts
(SPRINGER, 2022)Context is critical for conceptual processing, but the mechanism underpinning its encoding and reinstantiation during abstract concept processing is unclear. Context may be especially important for abstract concepts—we ... -
Functional characterization of correct and incorrect feature integration
(OXFORD, 2023)Our sensory system constantly receives information from the environment and our own body. Despite our impression to the contrary, we remain largely unaware of this information and often cannot report it correctly. Although ... -
Functional correlates of response inhibition in impulse control disorders in Parkinson’s disease
Esteban-Peñalba, Teresa
; ; ; (NeuroImage: Clinical, 2021)
Impulse control disorder is a prevalent side-effect of Parkinson’s disease (PD) medication, with a strong negative impact on the quality of life of those affected. Although impulsivity has classically been associated with ... -
Functional Dynamics of Dorsal and Ventral Reading Networks in Bilinguals
(Cerebral Cortex, 2017)In today’s world, bilingualism is increasingly common. However, it is still unclear how left-lateralized dorsal and ventral reading networks are tuned to reading in proficient second-language learners. Here, we investigated ... -
Functional Inhibitory Control Dynamics in Impulse Control Disorders in Parkinson’s Disease
(Movement Disorders, 2020)ABSTRACT: Background: Impulse control disorders related to alterations in the mesocorticolimbic dopamine network occur in Parkinson’s disease (PD). Our objective was to investigate the functional neural substrates ... -
Functional plasticity associated with language learning in adults
(NeuroImage, 2019)Learning a new language in adulthood is increasingly common and among the most difficult tasks attempted by adults. Adult language learners thus offer an excellent window into the nature of learning-dependent plasticity. ... -
Functional underpinnings of feedback-enhanced test-potentiated encoding
(OXFORD, 2023)The testing effect describes the finding that retrieval practice enhances memory performance compared to restudy practice. Prior evidence demonstrates that this effect can be boosted by providing feedback after retrieval ... -
High-Resolution Tractography Protocol to Investigate the Pathways between Human Mediodorsal Thalamic Nucleus and Prefrontal Cortex
(Jneurosci, 2023)Animal studies have established that the mediodorsal nucleus (MD) of the thalamus is heavily and reciprocally connected with all areas of the prefrontal cortex (PFC). In humans, however, these connections are difficult to ... -
How the human brain introspects about one's own episodes of cognitive control
Soto, David; Theodoraki, Mona; Paz-Alonso, Pedro M. (cortex, 2018)
Metacognition refers to our capacity to reflect upon our experiences, thoughts and actions. Metacognition processes are linked to cognitive control functions that allow keeping our actions on-task. But it is unclear how ... -
Interactions between functional networks in Parkinson's disease mild cognitive impairment
(NATURE, 2023)The study of mild cognitive impairment (MCI) is critical to understand the underlying processes of cognitive decline in Parkinson’s disease (PD). Functional connectivity (FC) disruptions in PD-MCI patients have been observed ... -
Interactions between phasic alerting and consciousness in the fronto-striatal network
(Scientific Reports, 2016)Only a small fraction of all the information reaching our senses can be the object of conscious report or voluntary action. Although some models propose that different attentional states (top-down amplification and ... -
Metacognitive scaffolding boosts cognitive and neural benefits following executive attention training in children
(Developmental Science, 2019)Interventions including social scaffolding and metacognitive strategies have been used in educational settings to promote cognition. In addition, increasing evidence shows that computerized process-based training enhances ...
