Gamma rhythms and beta rhythms have different synchronization properties [PDF]
Proceedings of the National Academy of Sciences, 2000 Experimental and modeling efforts suggest that rhythms in the CA1 region of the hippocampus that are in the beta range (12–29 Hz) have a different dynamical structure than that of gamma (30–70 Hz). We use a simplified model to show that the different rhythms employ different dynamical mechanisms to synchronize, based on different ionic currents.

The Study of Object-Oriented Motor Imagery Based on EEG Suppression. [PDF]
PLoS ONE, 2015 Motor imagery is a conventional method for brain computer interface and motor learning. To avoid the great individual difference of the motor imagery ability, object-oriented motor imagery was applied, and the effects were studied.

Beta and Gamma Rhythms Go with the Flow [PDF]
Neuron, 2015 Information flows through visual areas in opposite directions during "bottom-up" intake of current stimuli and "top-down" processes such as attention or memory. In this issue of Neuron, Bastos et al. (2015) report that rhythms of different frequencies coordinate bottom-up and top-down information streams.

The Semantics of Natural Objects and Tools in the Brain: A Combined Behavioral and MEG Study
Brain Sciences, 2022 Current literature supports the notion that the recognition of objects, when visually presented, is sub-served by neural structures different from those responsible for the semantic processing of their nouns.

Human motor cortical activity is selectively phase-entrained on underlying rhythms.
PLoS Computational Biology, 2012 The functional significance of electrical rhythms in the mammalian brain remains uncertain. In the motor cortex, the 12-20 Hz beta rhythm is known to transiently decrease in amplitude during movement, and to be altered in many motor diseases.

The Effect of Neurofeedback Training on Dynamic Balance of Young Men [PDF]
رشد و یادگیری حرکتی ورزشی, 2015 Physical balance is one of the important factors in daily sport activities.Dynamic balance helps maintain the balance of those forces imposed on body insports and an increase in this balance improves motor and sport performance.

Spontaneous Beta Band Rhythms in the Predictive Coding of Natural Stimuli [PDF]
The Neuroscientist, 2020 The regularity of the physical world and the biomechanics of the human body movements generate distributions of highly probable states that are internalized by the brain in the course of a lifetime. In Bayesian terms, the brain exploits prior knowledge, especially under conditions when sensory input is unavailable or uncertain, to predictively ...
