This article explores the contribution of differences in motor response initiation and execution to the biological bases of extraversion. Specifically, we examined individual differences in the lateralized readiness potential (LRP) for introverts and extraverts under conditions influencing stimulus evaluation time prior to response execution, i.e., stimulus information value and tonal complexity. The salient effects were longer stimulus-locked LRP and shorter response-locked LRP for extraverts than introverts to simple imperative stimuli to respond. The present studies (1) confirm that extraverts initiate movement faster and are less efficient than introverts in the processing of simple stimulus signals to respond and (2) endorse the view differences in sensory-motor processing are important determinants of variation in Extraversion.

Freya Bailes deals with the topic of musical imagery, and she uses embodied cognition as a framework to argue that musical imagery is a multimodal experience. Existing empirical studies of musical imagery are reviewed and Bailes points to future directions for the study of musical imagery as an embodied-cognition phenomenon. Arguing that musical imagery can never be fully disembodied, Bailes moves beyond the idea of auditory imagery as merely a simulation of auditory experience by “the mind’s ear.” Instead, she outlines how imagining sounds involves kinesthetic imagery and she concludes that sound and music are always connected to sensory motor processing.

The function of the nigro-striatal pathway on neuronal entropy in the basal ganglia (BG) output nucleus, i.e. the entopeduncular nucleus (EPN) was investigated in the unilaterally 6-hyroxydopamine (6-OHDA)-lesioned rat model of Parkinson’s disease (PD). In both control subjects and subjects with 6-OHDA lesion of dopamine (DA) the nigro-striatal pathway, a histological hallmark for parkinsonism, neuronal entropy in EPN was maximal in neurons with firing rates ranging between 15 and 25[Formula: see text]Hz. In 6-OHDA lesioned rats, neuronal entropy in the EPN was specifically higher in neurons with firing rates above 25[Formula: see text]Hz. Our data establishes that the nigro-striatal pathway controls neuronal entropy in motor circuitry and that the parkinsonian condition is associated with abnormal relationship between firing rate and neuronal entropy in BG output nuclei. The neuronal firing rates and entropy relationship provide putative relevant electrophysiological information to investigate the sensory-motor processing in normal condition and conditions such as movement disorders.

And Control

Sensory responses to stimuli that are triggered by a self-initiated motor act are suppressed when compared with the response to the same stimuli triggered externally, a phenomenon referred to as motor-induced suppression (MIS) of sensory cortical feedback. Studies in the somatosensory system suggest that such suppression might be sensitive to delays between the motor act and the stimulus onset, and a recent study in the auditory system suggests that such MIS develops rapidly. In three MEG experiments, we characterize the properties of MIS by examining the M100 response from the auditory cortex to a simple tone triggered by a button press. In Experiment 1, we found that MIS develops for zero delays but does not generalize to nonzero delays. In Experiment 2, we found that MIS developed for 100-msec delays within 300 trials and occurs in excess of auditory habituation. In Experiment 3, we found that unlike MIS for zero delays, MIS for nonzero delays does not exhibit sensitivity to sensory, delay, or motor-command changes. These results are discussed in relation to suppression to self-produced speech and a general model of sensory motor processing and control.
