Limits on the neutron-antineutron oscillation time from the stability of nuclei [PDF]

open access: yes, 1994
We refute a recent claim by Nazaruk that the limits placed on the free--space neutron--antineutron oscillation time $\tau_{{n\bar n}}$ can be improved by many orders of magnitude with respect to the estimate $\tau_{{n\bar n}}>2(T_0/\Gamma)^{1/2}$, where $

Optogenetically evoked gamma oscillations are disturbed by cocaine administration

open access: yesFrontiers in Cellular Neuroscience, 2013
Drugs of abuse have enormous societal impact by degrading the cognitive abilities, emotional state and social behavior of addicted individuals. Among other events involved in the addiction cycle, the study of a single exposure to cocaine, and the ...

Gamma oscillation plasticity is mediated via parvalbumin interneurons. [PDF]

open access: yesSci Adv, 2023
Understanding the plasticity of neuronal networks is an emerging field of (patho-) physiological research, yet the underlying cellular mechanisms remain poorly understood. Gamma oscillations (30 to 80 hertz), a biomarker of cognitive performance, require and potentiate glutamatergic transmission onto parvalbumin-positive interneurons (PVIs)

Neutrino Oscillation in Magnetized Gamma-Ray Burst Fireball [PDF]

open access: yes, 2009
Neutrinos of energy about 5-20 MeV are produced due to the stellar collapse or merger events that trigger the Gamma-Ray Burst. Also low energy MeV neutrinos are produced within the fireball due to electron positron annihilation and nucleonic ...

Parametric computation predicts a multiplicative interaction between synaptic strength parameters that controls properties of gamma oscillations

open access: yesFrontiers in Computational Neuroscience, 2012
Gamma oscillations are thought to be critical for a number of behavioural functions, they occur in many regions of the brain and through a variety of mechanisms.

Sensory gamma entrainment: Impact on amyloid protein and therapeutic mechanism

open access: yesBrain Research Bulletin, 2023
The deposition of amyloid β peptide (Aβ) is one of the main pathological features of AD. The much-talked sensory gamma entrainment may be a new treatment for Aβ load.

Gamma-oscillations from bench to bed [PDF]

open access: yesClinical Neurophysiology, 2012
In the presurgical evaluation of patients with pharmacoresistant epilepsies, the borders between disciplines tend to oscillate. In particular, the necessity to evaluate the functional capacity of a cortical area that has been shown to be epileptogenic and is thus being considered for resection often makes it impossible not to trespass between ...

Establishing communication between neuronal populations through competitive entrainment

open access: yesFrontiers in Computational Neuroscience, 2012
The role of gamma frequency oscillation in neuronal interaction, and the relationship between oscillation and information transfer between neurons, has been the focus of much recent research.

Gamma Oscillations and Emotional Memory [PDF]

open access: yes, 2022
Abstract Increased visual gamma band activity is known to relate to memory and encoding in cognitive tasks and has been shown to be present during arousing compared to neutral stimulus processing. Here, we set out to investigate whether gamma activity is stronger for later remembered compared to later forgotten emotional pictures ...

Suppression of Low-Frequency Gamma Oscillations by Activation of 40-Hz Oscillation [PDF]

open access: yesCerebral Cortex, 2021
Abstract Gamma oscillations have received considerable attention owing to their association with cognitive function and various neuropsychiatric disorders. However, interactions of gamma oscillations at different frequency bands in humans remain unclear. In the present magnetoencephalographic study, brain oscillations in a wide frequency
