Exploring the Effects of Breathing Exercises with a Humanoid Robot on Cognitive Functioning
… focusing on the theta, alpha, beta, and gamma bands. EDA (Electrodermal Activity) data was collected to see the physiological responsiveness. Additionally, cognitive assessments were conducted before and after the interventions, including memory, digit-span, and n-back tasks. The results …

Spectroscopic measurement of nitric oxide in a diffusion flame
… procedures. Ultraviolet absorption of the (1,0) gamma bands of nitric oxide near 214.8 nm were used for the spectroscopy. Spectroscopic measurements were possible only when the air stream was seeded with ca. 100 ppm NO. A conventional sampling system was operated at a probe pressure of 0.3 …

Efeitos dos estímulos elétricos senoidais na resposta induzida cerebral: estudo da seletividade das fibras sensitivas
… and ERD/ERS profiles of the alpha, beta, gamma and high-gamma bands were evaluated 3 kHz and 5 Hz, at intensities 1,2xLS, 2xLS and 3xLS. Results indicate habituation in the contralateral parietal region for the 3 kHz stimulus, as opposed to 5 Hz’s, at 1.2xLS in the alpha band. Results show …

Keep calm and age well: Behavioural and electrophysiological investigations into the effects of cumulative stress exposure on ageing cognition
… high stress individuals’ delta, theta, alpha and gamma bands and are thus the first to demonstrate that cumulative stress affects the underlying neural processes related to successful task execution. As such, from a methodological standpoint, the current research strongly advocates the use of …

Exploring the neural mechanisms underlying the speech processing and phonological deficits that characterise individuals with dyslexia
… phase entrainment (delta, theta, beta, low gamma), cerebro-acoustic coherence (delta and theta), band power (delta, theta, beta, low gamma), event-related potentials (ERPs), and cross-frequency coupling, including phase-amplitude coupling (PAC) and phase-phase coupling (PPC). PAC and PPC …

Brain computer interface using detection of movement intention
… relative power of the EEG in the alpha, beta and gamma bands during the time preceding movement initiation related to movement in different directions. Classification of single pre-movement EEG epochs based on Euclidean Distance, K-nearest neighbour and binary decision tree techniques resulted in …

Investigation of the Clinical Utility of the Spatio-Spectral Dynamics of Sensorimotor ECoG in Response to Different Somatosensory Stimulation Modalities in Human Subjects
… also investigated power modulations in ECoG sub-bands in response to mechanical tactile stimulation at the periphery during anesthetized (unconscious) and awake(conscious) states. Firstly, we show that by investigating the Spatio-temporal characteristics of the SSEP waveforms through an …

Nonuniform Power Changes and Spatial, Temporal and Spectral Diversity in High Gamma Band (>60 Hz) Signals in Human Electrocorticography
High-gamma band: >60Hz) power changes in cortical electrophysiology are a reliable indicator of focal, event-related cortical activity. In spite of discoveries of oscillatory subthreshold and synchronous suprathreshold activity at the cellular level, there is an increasingly popular view that …

Modulations of Electroencephalography signals in Response to experimental pain During Single Leg Cycling exercise
… stimuli on the dynamics of alpha, beta, and gamma frequency bands EEG signals. Methods: Twenty-one healthy, recreationally active participants underwent two testing sessions. In the first visit, participants were familiarized with experimental protocol and performed a ramp incremental cycling …

Search for Collective Strutures in the 186Os And 150Gd Nuclei
… underlying nature of such states, the excited bands in186Os and150Gd nuclei were investigated at iThemba laboratory for accelerator based sciences(iThemba LABS) using the186W(4He, 4n)186Os and150Sm(4He, 4n)150Gd reactions.The AFRODITEγ-ray spectrometer was used for detection ofγ-ray energies …
