Emotiv Epoc. Neural oscillation. Neural oscillation is rhythmic or repetitive neural activity in the central nervous system.
Neural tissue can generate oscillatory activity in many ways, driven either by mechanisms within individual neurons or by interactions between neurons. In individual neurons, oscillations can appear either as oscillations in membrane potential or as rhythmic patterns of action potentials, which then produce oscillatory activation of post-synaptic neurons. At the level of neural ensembles, synchronized activity of large numbers of neurons can give rise to macroscopic oscillations, which can be observed in the electroencephalogram (EEG).
Oscillatory activity in groups of neurons generally arises from feedback connections between the neurons that result in the synchronization of their firing patterns. The interaction between neurons can give rise to oscillations at a different frequency than the firing frequency of individual neurons. Simulation of neural oscillations at 10 Hz. Overview[edit] Evoked potential. Evoked potential amplitudes tend to be low, ranging from less than a microvolt to several microvolts, compared to tens of microvolts for EEG, millivolts for EMG, and often close to a volt for ECG.
To resolve these low-amplitude potentials against the background of ongoing EEG, ECG, EMG, and other biological signals and ambient noise, signal averaging is usually required. The signal is time-locked to the stimulus and most of the noise occurs randomly, allowing the noise to be averaged out with averaging of repeated responses.[1] Signals can be recorded from cerebral cortex, brain stem, spinal cord and peripheral nerves. Usually the term "evoked potential" is reserved for responses involving either recording from, or stimulation of, central nervous system structures. Sensory evoked potentials[edit] Long and Allen [3] reported the abnormal brainstem auditory evoked potentials (BAEP) in an alcoholic woman who recovered from Ondine's curse.

Research on meditation. Scenes of Inner Taksang, temple hall, built just above the cave where Padmasambhava is thought to have meditated Research on the processes and effects of meditation is a growing subfield of neurological research.[1][2][3][4][5][6] Modern scientific techniques and instruments, such as fMRI and EEG, have been used to see what happens in the body of people when they meditate, and how their bodies and brain change after meditating regularly.[2][7][8][9][10] Since the 1950s hundreds of studies on meditation have been conducted, though many of the early studies were flawed and thus yielded unreliable results.[11][12] More recent reviews have pointed out many of these flaws with the hope of guiding current research into a more fruitful path.[13] More reports assessed that further research needs to be directed towards the theoretical grounding and definition of meditation.[11][14] Meditation within Western psychology[edit] The relaxation response[edit] Dr.
