Frequency specificity of aberrant triple networks in major depressive disorder: a resting-state effective connectivity study

open access: yesFrontiers in Neuroscience, 2023
Major depressive disorder (MDD) has been associated with aberrant effective connectivity (EC) among the default mode network (DMN), salience network (SN), and central executive network (CEN)—collectively referred to as triple networks. However, prior research has predominantly concentrated on broad frequency bands (0.01–0.08 Hz or 0.01–0.15 Hz ...

Performance and Detection of M-ary Frequency Shift Keying in Triple Layer Wireless Sensor Network

open access: yesInternational journal of Computer Networks & Communications, 2012
This paper proposes an innovative triple layer Wireless Sensor Network (WSN) system, which monitors M-ary events like temperature, pressure, humidity, etc. with the help of geographically distributed sensors. The sensors convey signals to the fusion centre using M-ary Frequency Shift Keying (MFSK)modulation scheme over independent Rayleigh fading ...

Chiropractic Care Is Associated with Frequency-Specific Reorganisation of Triple-Network Brain Dynamics: A Source-Localised EEG Study

open access: yesBrain Sciences
Background/Objectives: Large-scale dysfunction in the default mode (DMN), salience (SN), and central executive (CEN) networks characterises conditions affecting affective, cognitive, and autonomic regulation. Chronic low back pain (CLBP) shows hyperactive salience signalling, disrupted DMN processing, and impaired executive regulation.
