On the origin of globular clusters in a hierarchical universe

Michaela Hirschmann

We present an end-to-end description of the formation of globular clusters (GCs) combining a treatment for their formation and dynamical evolution within galaxy haloes with a state-of-the-art semi-analytic simulation of galaxy formation. Our approach allow ...

Transcriptomic data meta-analysis reveals common and injury model specific gene expression changes in the regenerating zebrafish heart

Marius Alexandru Botos Rogozsan

Zebrafish have the capacity to fully regenerate the heart after an injury, which lies in sharp contrast to the irreversible loss of cardiomyocytes after a myocardial infarction in humans. Transcriptomics analysis has contributed to dissect underlying signa ...

Bodily self-consciousness as a framework to link sensory information and self-related components of episodic memory: behavioral, neuroimaging, and clinical evidence

Nathalie Heidi Meyer

The recollection of sensory information and subjective experience related to a personal past event depends on our episodic memory (EM). At the neural level, EM retrieval is linked with the reinstatement of hippocampal activity thought to recollect the sens ...

Cerebral Metabolic Dysfunction at the Acute Phase of Traumatic Brain Injury Correlates with Long-Term Tissue Loss

Ricardo Alberto Corredor Jerez

Following traumatic brain injury (TBI), cerebral metabolic dysfunction, characterized by an elevated cerebral microdialysis (CMD) lactate/pyruvate (LP) ratio, is associated with poor outcome. However, the exact pathophysiological mechanisms underlying this ...

Electrical spinal cord stimulation protocols to regulate neurological functions after spinal cord injury

Salif Axel Komi

Spinal cord injury (SCI) is a life-changing event. People who suffer from it lose their ability to move normally and are subject to life-threatening symptoms. When the insult is not too severe, partial recovery is possible. Otherwise, for severely affected ...

The perspectives of mapping and monitoring of the sense of self in neurosurgical patients

Olaf Blanke, Bruno Herbelin, Sophie Jacqueline Andrée Betka, Hyeongdong Park, Pavo Orepic, Sixto Luis Alcoba Banqueri

Surgical treatment of tumors, epileptic foci or of vascular origin, requires a detailed individual pre-surgical workup and intra-operative surveillance of brain functions to minimize the risk of post-surgical neurological deficits and decline of quality of ...

You, Cyborg ? Prosthetic Hybridation in Science-fiction Short Stories

Dominique Kunz Westerhoff

While science fiction has disseminated the Cyborg's concept in an vein of epic heroism, its literary history, from Cordwainer Smith to Martin Caitlin and Frederik Pohl, shows that it challenges constantly its ideal of continuity. From the start, the space ...

Resting-State Brain Activity for Early Prediction Outcome in Postanoxic Patients in a Coma with Indeterminate Clinical Prognosis

Dimitri Nestor Alice Van De Ville

The authors used resting-state fMRI in a prospective study to compare whole-brain functional connectivity between patients with good and poor outcomes, implementing support vector machine learning. They automatically predicted coma outcome using resting-st ...

Reactivation of Recall-Induced Neurons in the Infralimbic Cortex and the Basolateral Amygdala After Remote Fear Memory Attenuation

Johannes Gräff, Ossama Mohamed Salah El-Dien El-Sayed Ibrahim Khalaf

Whether the attenuation of traumatic memories is mediated through the suppression of the original memory trace of fear by a new memory trace of safety, or through an updating of the original fear trace towards safety has been a long-standing question at th ...

Long-term verbal memory deficit and associated hippocampal alterations in 22q11.2 deletion syndrome

Daniela Maria Zöller, Maude Schneider

Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a genetic disease associated with an increased risk for schizophrenia and a specific cognitive profile. In this paper, we challenge the current view of spared verbal memory in 22q11.2DS by investigating v ...

Mortality in Different Mountain Sports Activities Primarily Practiced in the Winter Season—A Narrative Review

Johannes Burtscher

Annually, millions of people engage in mountain sports activities all over the world. These activities are associated with health benefits, but concurrently with a risk for injury and death. Knowledge on death rates is considered important for the categori ...

Central nervous system microbleeds in the acute phase are associated with structural integrity by DTI one year after mild traumatic brain injury: A longitudinal study

Jean-Philippe Thiran, Alessandro Daducci, David Paul Roger Romascano

Introduction: Several imaging modalities are under investigation to unravel the pathophysiological mystery of delayed performance deficits in patients after mild traumatic brain injury (mTBI). Although both imaging and neuropsychological studies have been ...

Neuroprosthetics to support impaired hand functions: A multidisciplinary approach combining brain-machine interfaces and wearable exoskeletons

Luca Randazzo

Neuroprosthetics, the discipline that aims at interfacing neural systems to artificially engineered devices, has witnessed in recent years important advancements towards the ultimate goal of augmenting and restoring human functions through technology and a ...

In the pursuit of the fear engram: identification of neuronal circuits underlying the treatment of anxiety disorder

Ossama Mohamed Salah El-Dien El-Sayed Ibrahim Khalaf

Fear and other anxiety disorders are extraordinarily robust and difficult to treat. Among the most effective treatments for anxiety disorders are exposure-based therapies, during which a patient is repeatedly confronted with the originally fear-eliciting s ...

FORMINg a link between PTSD and AD

Johannes Gräff

Epidemiological evidence suggests that people suffering from post-traumatic stress disorder have a higher risk for developing Alzheimer's disease. The underlying mechanisms, however, remained thus far unexplored. In this issue of The EMBO Journal, Agis-Bal ...

Eyetracking shows the source of age-related differences in prospective memory: Older adults monitor well, but fail to take action

Michael Herzog, Marc Michael Lauffs

Older adults often perform worse than younger adults on prospective memory tasks, but the exact mechanisms remain elusive. Participants had to indicate whether a letter in the center of gaze is a vocal or a consonant (ongoing task). The prospective memory ...

EEG paradigms as a supplemental tool to behavioral assessments of DOC

José del Rocio Millán Ruiz, Andrea Serino, Serafeim Perdikis

Introduction Diagnosis and prediction of recovery in the acute phase of disorders of consciousness (DOC) are critical for subsequent medical decisions. However, reliable assessment remains elusive due to the inability of current validated clinical scales t ...

Improvement of Neuroenergetics by Hypertonic Lactate Therapy in Patients with Traumatic Brain Injury Is Dependent on Baseline Cerebral Lactate/Pyruvate Ratio

Pierre Magistretti, Reto Meuli

Energy dysfunction is associated with worse prognosis after traumatic brain injury (TBI). Recent data suggest that hypertonic sodium lactate infusion (HL) improves energy metabolism after TBI. Here, we specifically examined whether the efficacy of HL (3h i ...

Emergence in extinction of enhanced and persistent responding to ambiguous aversive cues is associated with high MAOA activity in the prelimbic cortex

Maria del Carmen Sandi Perez, Guillaume Poirier

There is a great deal of individual variability in the emotional outcomes of potentially traumatic events, and the underlying mechanisms are only beginning to be understood. In order to further our understanding of individual trajectories to trauma, its vu ...
