Mirror Neurons System Engagement in Late Adolescents and Adults While Viewing Emotional Gestures [PDF]

, 2016
International audienceObserving others' actions enhances muscle-specific cortico-spinal excitability, reflecting putative mirror neurons activity. The exposure to emotional stimuli also modulates cortico-spinal excitability. We investigated how those two

fMRI Investigation of Cortical and Subcortical Networks in the Learning of Abstract and Effector-Specific Representations of Motor Sequences [PDF]

, 2006
A visuomotor sequence can be learned as a series of visuo-spatial cues or as a sequence of effector movements. Earlier imaging studies have revealed that a network of brain areas is activated in the course of motor sequence learning.

Observing Without Acting: A Balance of Excitation and Suppression in the Human Corticospinal Pathway?

Frontiers in Neuroscience, 2018
Transcranial magnetic stimulation (TMS) studies of human primary motor cortex (M1) indicate an increase corticospinal excitability during the observation of another's action.

Motor resonance in monkey parietal and premotor cortex during action observation: Influence of viewing perspective and effector identity

NeuroImage, 2021
Observing others performing motor acts like grasping has been shown to elicit neural responses in the observer`s parieto-frontal motor network, which typically becomes active when the observer would perform these actions him/herself.

Hitting is male, giving is female. Automatic imitation and complementarity during action observation [PDF]

, 2016
Is somebody going to hurt us? We draw back. The present study investigates using behavioral measures the interplay between imitative and complementary actions activated while observing female/male hands performing different ...

Motor resonance is modulated by an object's weight distribution [PDF]

Neuropsychologia, 2020
AbstractTranscranial magnetic stimulation (TMS) studies showed that corticospinal excitability (CSE) is modulated during observation of object lifting, an effect termed ‘motor resonance’. Specifically, motor resonance is driven by movement features indicating object weight, such as object size or observed movement kinematics.

Step size of the rotary proton motor in single FoF1-ATP synthase from a thermoalkaliphilic bacterium by DCO-ALEX FRET

, 2012
Thermophilic enzymes can operate at higher temperatures but show reduced activities at room temperature. They are in general more stable during preparation and, accordingly, are considered to be more rigid in structure.

Ready ... Go: Amplitude of the fMRI Signal Encodes Expectation of Cue Arrival Time [PDF]

, 2009
What happens when the brain awaits a signal of uncertain arrival time, as when a sprinter waits for the starting pistol? And what happens just after the starting pistol fires? Using functional magnetic resonance imaging (fMRI), we have discovered a novel

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Vitality Forms Expressed by Others Modulate Our Own Motor Response: A Kinematic Study

Frontiers in Human Neuroscience, 2017
During social interaction, actions, and words may be expressed in different ways, for example, gently or rudely. A handshake can be gentle or vigorous and, similarly, tone of voice can be pleasant or rude.
