EEG signals index a global signature of arousal embedded in neuronal population recordings.

eNeuro 2022 May 19. Epub 2022 May 19.

Department of Biomedical Engineering, Carnegie Mellon University, Pittsburgh, USA

Electroencephalography (EEG) has long been used to index brain states, from early studies describing activity in the presence and absence of visual stimulation to modern work employing complex perceptual tasks. These studies have shed light on brain-wide signals but often lack explanatory power at the single neuron level. Similarly, single neuron recordings can suffer from an inability to measure brain-wide signals accessible using EEG. Read More

Equipoise, standard of care and consent: responding to the authorisation of new COVID-19 treatments in randomised controlled trials.

J Med Ethics 2022 May 23. Epub 2022 May 23.

Health Research Institute-Fundación Jiménez Díaz University Hospital, Universidad Autonoma de Madrid, Madrid, Spain.

In response to the COVID-19 pandemic, large-scale research and pharmaceutical regulatory processes have proceeded at a dramatically increased pace with new and effective, evidence-based COVID-19 interventions rapidly making their way into the clinic. However, the swift generation of high-quality evidence and the efficient processing of regulatory authorisation have given rise to more specific and complex versions of well-known research ethics issues. In this paper, we identify three such issues by focusing on the authorisation of molnupiravir, a novel antiviral medicine aimed at reducing the ability of SARS-CoV-2 to multiply in the body, for clinical use by the National Health Service in England and the concomitant testing of molnupiravir through the large-scale Platform Adaptive trial of Novel antiviRals for eArly treatMent of COVID-19 In the Community randomised control trial.

Thalamic activity during scalp slow waves in humans.

Neuroimage 2022 May 20:119325. Epub 2022 May 20.

Institute of Behavioural Sciences, Semmelweis University, Budapest, Hungary; National Institute of Clinical Neuroscience, Budapest, Hungary.

Slow waves are major pacemakers of NREM sleep oscillations. While slow waves themselves are mainly generated by cortical neurons, it is not clear what role thalamic activity plays in the generation of some oscillations grouped by slow waves, and to what extent thalamic activity during slow waves is itself driven by corticothalamic inputs. To address this question, we simultaneously recorded both scalp EEG and local field potentials from six thalamic nuclei (bilateral anterior, mediodorsal and ventral anterior) in fifteen epileptic patients (age-range: 17-64 years, 7 females) undergoing Deep Brain Stimulation Protocol and assessed the temporal evolution of thalamic activity relative to scalp slow waves using time-frequency analysis.
