Grasping the semantic of actions: a combined behavioral and MEG study
Frontiers in Human Neuroscience, 2022 There is experimental evidence that the brain systems involved in action execution also play a role in action observation and understanding. Recently, it has been suggested that the sensorimotor system is also involved in language processing.

Brain Stimulation, 2022 Background: Neural oscillations in the primary motor cortex (M1) shape corticospinal excitability. Power and phase of ongoing mu (8–13 Hz) and beta (14–30 Hz) activity may mediate motor cortical output.

Cortical processing during robot and functional electrical stimulation
Frontiers in Systems Neuroscience, 2023 IntroductionLike alpha rhythm, the somatosensory mu rhythm is suppressed in the presence of somatosensory inputs by implying cortical excitation. Sensorimotor rhythm (SMR) can be classified into two oscillatory frequency components: mu rhythm (8–13 Hz ...

Alpha, beta: The rhythm of the attentional blink [PDF]
Psychonomic Bulletin & Review, 2017 Extant theories of the attentional blink propose that the most critical factor in determining second target accuracy is the time that elapses between the first and second targets. We report that this conclusion has overlooked an equally important determinant, namely, the frequency of the entraining stream in which these targets are embedded ...

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.

Dopaminergic drugs alter beta coherence during motor imagery and motor execution in healthy adults [PDF]
Arquivos de Neuro-Psiquiatria, 2020 Background: Motor Imagery (MI) represents the cognitive component of the movement and recruits dopaminergic systems. Objective: To investigate the role of dopaminergic system through the action of methylphenidate and risperidone over beta coherence ...

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.

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.

Translation of EEG spatial filters from resting to motor imagery using independent component analysis. [PDF]
, 2012 Electroencephalogram (EEG)-based brain-computer interfaces (BCIs) often use spatial filters to improve signal-to-noise ratio of task-related EEG activities.
