Depressive Disorder Recognition Based on Frontal EEG Signals and Deep Learning

open access: yesSensors, 2023
Depressive disorder (DD) has become one of the most common mental diseases, seriously endangering both the affected person’s psychological and physical health.

Beta‐blocker use and mortality among patients with systolic heart failure and pacemaker rhythm

open access: yesESC Heart Failure, 2023
Aims Beta‐blockers are proven to improve survival among patients with heart failure with reduced ejection fraction. Their efficacy in patients with heart failure with reduced ejection fraction and pacemaker devices has not been demonstrated.

Interacting rhythms enhance sensitivity of target detection in a fronto-parietal computational model of visual attention

open access: yeseLife, 2023
Even during sustained attention, enhanced processing of attended stimuli waxes and wanes rhythmically, with periods of enhanced and relatively diminished visual processing (and subsequent target detection) alternating at 4 or 8 Hz in a sustained visual ...

Grasping the semantic of actions: a combined behavioral and MEG study

open access: yesFrontiers 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.

The phase of sensorimotor mu and beta oscillations has the opposite effect on corticospinal excitability

open access: yesBrain 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

open access: yesFrontiers 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]

open access: yesPsychonomic 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]

open access: yesPLoS 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]

open access: yesArquivos 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]

open access: yesProceedings 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.
