Beta Electroencephalographic Oscillation Is a Potential GABAergic Biomarker of Chronic Peripheral Neuropathic Pain [PDF]
Frontiers in Neuroscience, 2021 This preliminary investigation aimed to assess beta (β) oscillation, a marker of the brain GABAergic signaling, as a potential objective pain marker, hence contributing at the same time to the mechanistic approach of pain management.

Synchronously pumped optical parametric oscillation in beta-barium borate
Optics Communications, 1988 Optical parametric oscillation in beta-barium borate has been demonstrated using synchronous pumping by the frequency doubled output train from an actively mode-locked and Q-switched Nd:YAG laser. The parametric oscillator converts up to ~30% of the pump

Beta-gamma oscillation reveals learning from unexpected reward in learners versus non-learners [PDF]
Neuropsychologia, 2019 Beta-gamma oscillation has been demonstrated to be sensitive to unexpected reward feedback. However, it remains unclear whether beta-gamma activity manifests individual differences in reinforcement learning processing.

Primate beta oscillations and rhythmic behaviors
Journal of Neural Transmission, 2017The study of non-human primates in complex behaviors such as rhythm perception and entrainment is critical to understand the neurophysiological basis of human cognition. Next to reviewing the role of beta oscillations in human beat perception, here we discuss the role of primate putaminal oscillatory activity in the control of rhythmic movements that ...

Gamma/beta oscillation and sensory gating deficit in schizophrenia
NeuroReport, 2004Sensory gating can be measured by the suppression of auditory evoked potentials in a paired-click paradigm. The normal gating of the P50 response to the second stimulus (S2) is impaired in many schizophrenic patients. Various in vitro and in vivo evoked potential paradigms have shown that a stimulus evokes early gamma frequency oscillation, which is ...

Sensitivity of frontal beta oscillations to reward valence but not probability
Neuroscience Letters, 2015Reward feedback elicits a brief increase in power in the high-beta frequency range of the human electroencephalogram (EEG) over frontal areas of the scalp, but the functional role of this oscillatory activity remains unclear. An observed sensitivity to reward expectation (HajiHosseini, Rodríguez-Fornells, and Marco-Pallarés, 2012; [2]) suggests that ...

Transistor Beta-phase-shift Oscillator†
Journal of Electronics and Control, 1960ABSTRACT A new junction-transistor oscillator circuit is described. It makes use of the internal phase-shift of a transistor and only a single C-R section as the external phase-shifting network—advantage being taken of the low-input impedance of a common emitter junction transistor.

Synchrony of Cortical Alpha and Beta Oscillations
2017We analyzed behavior of cortical alpha and beta oscillations during preparation of self-paced finger movement. Magnetic field patterns around the head were complex during rhythmic events, implying several simultaneously active sources. Oscillations in the cortical sites separated by a few centimeters were highly synchronized.
