Aging and the Spectral Properties of Brain Hemodynamics
Advanced Science, EarlyView.As the brain ages, its metabolic demands decline—but not uniformly. Here, spectral slope flattening of resting‐state fMRI signals is proposed as a potential biomarker of pathologic brain aging. A subset of older adults diverges from youthful spectral and metabolic patterns, with changes linked to frontal white matter pathology and regional loss of ...

Advanced Science, EarlyView.Lynch et al., identified novel targets on the wake‐promoting pathways that can effectively treat pain‐induced sleep disturbances. The authors demonstrated that Calcitonin gene‐related peptide‐expressing neurons (CGRP) in the external lateral parabrachial nucleus (PBelCGRP) serve as the primary relay node for pain stimuli that cause sleep disruption ...

Multi-Class SVM Based on Sleep Stage Identification Using EEG Signal [PDF]
, 2015 Currently, sleep disorders are considered as one of the major human life issues. Human sleep is a regular state of rest for the body in which the eyes are not only usually closed, but also have several nervous centers being inactive; hence, rendering the

Intestinal Clock Promotes Cognitive Memory Through Adenosine Signaling
Advanced Science, EarlyView.The intestinal clock controls the expression of an adenosine enzyme that modulates systemic adenosine level and A1R signaling in the hippocampus, and in turn, cognitive function involving long‐term potentiation and BDNF‐dependent synaptic changes.

The efficacy of transcranial current stimulation techniques to modulate resting-state EEG, to affect vigilance and to promote sleepiness [PDF]
, 2018 Transcranial Current Stimulations (tCSs) are non-invasive brain stimulation techniques which modulate cortical excitability and spontaneous brain activity by the application of weak electric currents through the scalp, in a safe, economic, and well ...

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.ABSTRACT Women with the FMR1 premutation (FXpm) are at heightened genetic vulnerability for depression, with risk compounded by the stressors of parenting a disabled child. Although risk factors persist as FXpm women age, depression in FXpm mothers during midlife and old age is poorly characterized. This study used an accelerated longitudinal design to

The sleep cycle: a mathematical analysis from a global workspace perspective [PDF]
, 2005 Dretske's technique of invoking necessary conditions from information theory to describe mental process can be used to derive a version of Hobson's AIM treatment of the sleep/wake cycle from a mathematical formulation of Baars' Global Workspace model of ...
