This study examines the electrophysiological correlates of dyadic interaction in 14-month-old infants. Infants were presented with three conditions of live stimuli. A baseline condition involved the observation of moving geometric shapes. In a second condition the infant observed an adult performing movements that were not in reference to the infant and were not within the infant's proficient m...

Perceived density was examined as two architectural design features were varied: wider wall location in trapezoid-shaped apartments and window size. Subjects rated perceived positive affect following presentation of apartment units with these changed but the same amount space. Two electroencephalogram (EEG) measures examined: event-related desynchronization modulation (Mu-Rhythm) Theta power – ...

Motor involvement in speech perception has been recently studied using a variety of techniques. In the current study, EEG measurements from Cz, C3 and C4 electrodes were used to examine the relative power of the mu rhythm (i.e., 8-13 Hz) in response to various audio-visual speech and non-speech stimuli, as suppression of these rhythms is considered an index of 'mirror neuron' (i.e., motor) acti...

BACKGROUND Event related desynchronization (ERD) of mu waves, or mu suppression, over sensorimotor cortex has been observed in response to self-generated movement, viewing movement, or imaging movement. Mu suppression is especially pronounced when the movement has social relevance and is being generated by a biological entity indicating successful social adaptation. And since social adaptation ...

Background: Electroencephalogram (EEG)-based brain-computer interfaces (BCI) represent a promising component of restorative motor therapies in individuals with partial paralysis. However, in those patients, sensory functions such as proprioception are at least partly preserved. The aim of this study was to investigate whether afferent feedback interferes with the BCI-based detection of efferent...

The influence of morphine dosing time on analgesic effect after acute or chronic treatment, recovery of analgesic effect after once developed tolerance, and their pharmacological mechanisms were investigated in ICR male mice under a 12-h light/dark cycle (light on from 7:00 AM to 7:00 PM). There was a significant 24-h rhythm in the latency of thermal response at 30 min after morphine injection....

Cortical rhythms in the alpha/mu frequency range (7-12 Hz) have been variously related to "idling," anticipation, seizure, and short-term or working memory. This overabundance of interpretations suggests that sensory cortex may be able to produce more than one (and even more than two) distinct alpha/mu rhythms. Here we describe simultaneous local field potential and single-neuron recordings mad...
