<p>In this paper a novel methodology is proposed to identify and compare the frequency range of different Vedic chantings from Rig Veda, Yajur Atharva Veda Sama Veda. Nowadays in spite busy schedule hectic work, human beings are mostly stressed. To get rid stressed state, one best solutions listening chantings. The alpha brainwaves 8-12 Hz under giving relaxation being. Three selected sam...

Noradrenergic neurons in the locus ceruleus contain neuropeptide Y and galanin, which project to the hypothalamic region. We have investigated the regulatory mechanisms of these peptides on norepinephrine release in rat hypothalamic slices in vitro. Neuropeptide Y and galanin significantly inhibited the stimulation-evoked [3H]norepinephrine release in a dose-dependent manner (1 Hz: S2/S1 ratio ...

The paper summarises the results of experiments carried out to investigate the e ect of a narrow-band noise in the range 4 8 Hz and of the acoustic pressure SPL = 110 dB(HP) on the alpha waves in the EEG signal. The test group included 23 males aged 21 33. It is found out that white noise in the infrasound range 4 8Hz leads to changes of amplitudes of the spectral power density of alpha waves. ...

We investigate the extent to which functional circuits coupling cortical and subthalamic activity are multiple and segregated by frequency in untreated Parkinson's disease (PD). To this end, we recorded EEG and local field potentials (LFPs) from macroelectrodes inserted into the subthalamic nucleus area (SA) in nine awake patients following functional neurosurgery for PD. Patients were studied ...

Long-term Vipassana meditators sat in meditation vs. a control (instructed mind wandering) states for 25 min, electroencephalography (EEG) was recorded and condition order counterbalanced. For the last 4 min, a three-stimulus auditory oddball series was presented during both meditation and control periods through headphones and no task imposed. Time-frequency analysis demonstrated that meditati...

Previous findings demonstrated that haplotype B of CST3, the gene coding for cystatin C, is a recessive risk factor for late-onset Alzheimer's disease (AD; Finckh, U., von der Kammer, H., Velden, J., Michel, T., Andresen, B., Deng, A., Zhang, J., Muller-Thomsen, T., Zuchowski, K., Menzer, G., Mann, U., Papassotiropoulos, A., Heun, R., Zurdel, J., Holst, F., Benussi, L., Stoppe, G., Reiss, J., M...

We applied magnetoencephalography (MEG) to record oscillatory brain activity from human subjects engaged in planning a double-step saccade. In the experiments, subjects (n = 8) remembered the locations of 2 sequentially flashed targets (each followed by a 2-s delay), presented in either the left or right visual hemifield, and then made saccades to the 2 locations in sequence. We examined change...

An attempt was made to quantitatively analyze the alpha activity in the awake relaxed state of Amyotrophic Lateral Sclerosis (ALS) patients and was compared with normals. ALS patients showed significantly low amplitude with a corresponding alpha band (8-13 Hz) power reduction, in both hemispheres though the change was more prominent in the left hemisphere. A review of the literature revealed no...

BACKGROUND Electroencephalogram patterns observed during sedation with dexmedetomidine appear similar to those observed during general anesthesia with propofol. This is evident with the occurrence of slow (0.1 to 1 Hz), delta (1 to 4 Hz), propofol-induced alpha (8 to 12 Hz), and dexmedetomidine-induced spindle (12 to 16 Hz) oscillations. However, these drugs have different molecular mechanisms ...
