Comparison of the effect of electromyogram activity during emergence on anesthetic depth monitoring between phase lag entropy and bispectral index: a prospective observational study.

Ann Palliat Med 2021 Jul 14. Epub 2021 Jul 14.

Department of Anesthesia and Pain Medicine, Pusan National University Yangsan Hospital, Yangsan, Republic of Korea.

Background: The bispectral index (BIS) is the most widely used algorithm for measuring anesthetic depth. The BIS has been demonstrated as inaccurate when neuromuscular blocking drugs (NMBDs) are used. Compared with BIS, phase lag entropy (PLE), which measures the anesthetic depth based on a 4-channel EEG signal, is less affected by EMG. Read More

Neural attentional-filter mechanisms of listening success in middle-aged and older individuals.

Nat Commun 2021 07 26;12(1):4533. Epub 2021 Jul 26.

Department of Psychology, University of Lübeck, Lübeck, Germany.

Successful listening crucially depends on intact attentional filters that separate relevant from irrelevant information. Research into their neurobiological implementation has focused on two potential auditory filter strategies: the lateralization of alpha power and selective neural speech tracking. However, the functional interplay of the two neural filter strategies and their potency to index listening success in an ageing population remains unclear. Read More

Electrophysiological Proxy of Cognitive Reserve Index.

Front Hum Neurosci 2021 8;15:690856. Epub 2021 Jul 8.

Laboratory for Neuro- and Psychophysiology, Department of Neurosciences, KU Leuven, Leuven, Belgium.

Cognitive reserve (CR) postulates that individual differences in task performance can be attributed to differences in the brain's ability to recruit additional networks or adopt alternative cognitive strategies. Variables that are descriptive of lifetime experience such as socioeconomic status, educational attainment, and leisure activity are common proxies of CR. CR is mostly studied using neuroimaging techniques such as functional MRI (fMRI) in which case individuals with a higher CR were observed to activate a smaller brain network compared to individuals with a lower CR, when performing a task equally effectively (higher efficiency), and electroencephalography (EEG) where a particular EEG component (P300) that reflects the attention and working memory load, has been targeted.

Modulation of Frontal Oscillatory Power during Blink Suppression in Children: Effects of Premonitory Urge and Reward.

Cereb Cortex Commun 2020 6;1(1):tgaa046. Epub 2020 Aug 6.

Semel Institute for Neuroscience and Human Behavior, University of California Los Angeles, Los Angeles, CA 90095, USA.

There is a dearth of studies examining the underlying mechanisms of blink suppression and the effects of urge and reward, particularly those measuring subsecond electroencephalogram (EEG) brain dynamics. To address these issues, we designed an EEG study to ask 3 questions: 1) How does urge develop? 2) What are EEG-correlates of blink suppression? 3) How does reward change brain dynamics related to urge suppression? This study examined healthy children ( = 26, age 8-12 years) during blink suppression under 3 conditions: blink freely (i.e. Read More

Using different methods for calculating frontal alpha asymmetry to study its development from infancy to 3 years of age in a large longitudinal sample.

Dev Psychobiol 2021 Jul 22. Epub 2021 Jul 22.

Laboratories of Cognitive Neuroscience, Division of Developmental Medicine, Boston Children's Hospital, Boston, Massachusetts, USA.

Frontal electroencephalography (EEG) alpha asymmetry (FAA), defined as the difference in frontal alpha power observed over the right and left frontal scalp regions, has been widely used in developmental research as a measure of multiple aspects of child behavior, such as temperament. Studies have used different equations to calculate FAA, which renders comparison of results across studies challenging. Furthermore, few studies have examined FAA's longitudinal stability across infancy and early childhood, which is a desirable feature of a temperament measure. Read More

Clin Neurophysiol 2021 Jun 20;132(9):2136-2145. Epub 2021 Jun 20.

Aston Institute of Health and Neurodevelopment, College of Health and Life Sciences, Aston University, Birmingham, UK; Children's Epilepsy Surgery Program, The Birmingham Women's and Children's NHS Foundation Trust, Birmingham, UK.

Objective: To assess the feasibility of automatically detecting high frequency oscillations (HFOs) in magnetoencephalography (MEG) recordings in a group of ten paediatric epilepsy surgery patients who had undergone intracranial electroencephalography (iEEG).

Methods: A beamforming source-analysis method was used to construct virtual sensors and an automatic algorithm was applied to detect HFOs (80-250 Hz). We evaluated the concordance of MEG findings with the sources of iEEG HFOs, the clinically defined seizure onset zone (SOZ), the location of resected brain structures, and with post-operative outcome.

Front Psychiatry 2021 25;12:574482. Epub 2021 Jun 25.

Cumulus Neuroscience Ltd, Belfast, United Kingdom.

Access to affordable, objective and scalable biomarkers of brain function is needed to transform the healthcare burden of neuropsychiatric and neurodegenerative disease. Electroencephalography (EEG) recordings, both resting and in combination with targeted cognitive tasks, have demonstrated utility in tracking disease state and therapy response in a range of conditions from schizophrenia to Alzheimer's disease. But conventional methods of recording this data involve burdensome clinic visits, and behavioural tasks that are not effective in frequent repeated use. Read More

Connectivity Measures Differentiate Cortical and Subcortical Sub-Acute Ischemic Stroke Patients.

Front Hum Neurosci 2021 1;15:669915. Epub 2021 Jul 1.

Unit of Neurorehabilitation, Department of Medical Specialties, University Hospital of Pisa, Pisa, Italy.

Brain lesions caused by cerebral ischemia lead to network disturbances in both hemispheres, causing a subsequent reorganization of functional connectivity both locally and remotely with respect to the injury. Quantitative electroencephalography (qEEG) methods have long been used for exploring brain electrical activity and functional connectivity modifications after stroke. However, results obtained so far are not univocal. Read More
