On the physiological modulation and potential mechanisms underlying parieto-occipital alpha oscillations
(Frontiers in Computational Neuroscience, 2018)The parieto-occipital alpha (8–13 Hz) rhythm is by far the strongest spectral fingerprint in the human brain. Almost 90 years later, its physiological origin is still far from clear. In this Research ... -
The hidden spatial dimension of alpha: 10-Hz perceptual Echoes propagate as periodic traveling waves in the human brain
(Cell Reports, 2019)EEG reverse-correlation techniques have revealed that visual information processing entails a ∼10-Hz (alpha) occipital response that reverberates sensory inputs up to 1 s. However, the spatial distribution ... -
Pinging the brain with visual impulses reveals electrically active, not activity-silent, working memories
(PLOS Biology, 2021)Persistently active neurons during mnemonic periods have been regarded as the mechanism underlying working memory maintenance. Alternatively, neuronal networks could instead store memories in fast ... -
A ventromedial prefrontal dysrhythmia in obsessive-compulsive disorder is attenuated by nucleus accumbens deep brain stimulation
(Brain Stimulation, 2021)Background: Obsessive-compulsive disorder (OCD) has consistently been linked to abnormal frontostriatal activity. The electrophysiological disruption in this circuit, however, remains to be characterized. ... -
A personalizable autonomous neural mass model of epileptic seizures
(Journal of Neural Engineering, 2022)Work in the last two decades has shown that neural mass models (NMM) can realistically reproduce and explain epileptic seizure transitions as recorded by electrophysiological methods (EEG, SEEG). In ... -
LSD-induced increase of Ising temperature and algorithmic complexity of brain dynamics
(PLOS Computational Biology, 2023)A topic of growing interest in computational neuroscience is the discovery of fundamental principles underlying global dynamics and the self-organization of the brain. In particular, the notion that the ... -
Gamma amplitude is coupled to opposed hippocampal theta-phase states during the encoding and retrieval of episodic memories in humans
(Current Biology, 2023)Computational models and in vivo studies in rodents suggest that the emergence of gamma activity (40–140 Hz) during memory encoding and retrieval is coupled to opposed-phase states of the underlying ... -
Aversive memory formation in humans involves an amygdala-hippocampus phase code
(Nature Communications, 2022)Memory for aversive events is central to survival but can become maladaptive in psychiatric disorders. Memory enhancement for emotional events is thought to depend on amygdala modulation of hippocampal ... -
Neural signatures of reduced serial dependence in anti-NMDAR encephalitis and schizophrenia
(2024)Serial dependence, a behavioral phenomenon where information from previous trials biases current trial reports, is pervasive in working memory tasks. There is growing interest in its mechanisms, and ... -
Experiences and needs of nursing students during pandemic outbreaks: A systematic overview of the literature
(Journal of Professional Nursing, 2021)Background: Recent epidemics have placed overwhelming demands on health systems, leading at times to the deployment of nursing students during the crisis. Little is known about the impact this experience ... -
Development of a guide to multidimensional needs assessment in the palliative care initial encounter (MAP)
(Journal of Pain and Symptom Management, 2023)Context: Ensuring patient-centered palliative care requires a comprehensive assessment of needs beginning in the initial encounter. However, there is no generally accepted guide for carrying out this ... -
What defines the comprehensive assessment of needs in palliative care? An integrative systematic review
(Palliative Medicine, 2021)Background: The comprehensive assessment of needs in palliative care identifies where patients most want attention to guide clinical decisions that tailor care provision from their first encounters. ... -
Aspectos éticos relacionados con el uso de información tecnológica en nuevas aplicaciones quirúrgicas: tele-cirugía y tele-tutoría
(Acta Bioethica, 2018)Background: The surgical telementoring is a technology that involves surgical procedures guided by an expert or mentor, performed by other surgeons from a distance, using information and knowledge ... -
Ethical issues in surgical tele mentoring: challenges and dilemmas of an innovative technology

Usefulness of the holistic context of frailty as a prognostic factor for the outcome of geriatric patients undergoing emergency abdominal surgery
(European Surgery, 2019)Background: This study aims to assess frailty in a holistic context as a prognostic factor for the outcomes of a group of geriatric patients undergoing emergency abdominal surgery, identifying the ... -
Is the precautionary principle adaptable to emergency scenarios to speed up research, risking the individual informed consent?
(American Journal of Bioethics, 2013) -
Opportunity cost in the economic evaluation of da Vinci robotic assisted surgery
(The European Journal of Health Economics, 2016)Objective: This study aims to demonstrate the importance of the opportunity cost in using da Vinci robotic surgery, assisted by a comprehensive review of the literature to determine the differences in ... -
Opportunity cost of the dermatologist's consulting time in the economic evaluation of teledermatology
(Journal of Telemedicine and Telecare, 2016)Introduction: This study, through a systematic review and meta-analysis, has sought to demonstrate that the opportunity cost is a value to take into account in studies of economic cost in telemedicine, ... -
The impact of frailty on the economic evaluation of geriatric surgery: hospital costs and opportunity costs based on meta-analysis
(Journal of Medical Economics, 2020)Objectives: We used a systematic review and meta-analysis to analyze the difference in costs between surgery for frail and non-frail elderly patients. The opportunity cost of frailty in geriatric surgery ...
