Physical or Cognitive Exertion Does Not Influence Cortical Movement Preparation for Rapid Arm Movements

Foreign accent does not influence cognitive judgments

A recent paper by Lev-Ari and Keysar (2010) reported that the processing fluency associated with non-native speech causes non-native speakers to sound less credible. The authors found that the same trivia statements were rated as less truthful when spoken by a non-native speaker of English. The present paper reports the results of three studies that attempted to replicate the findings of Lev-Ar...

Adaptation in Cortical Control of Arm Movement

By simultaneously recording multi-neuronal activities through chronically implanted electrode arrays in motor and sensory cortices, arm movement trajectory, and muscle activities, we observed both spatial and temporal differences in neuronal activities during different phases of a reaching task. We also discovered that when developing an effective control strategy to overcome an externally appl...

Volatile anesthesia does not satisfy rapid eye movement sleep debt.

A common statement made to patients before they undergo a general anesthetic is, “We will watch you very carefully while you are asleep.” The relationship between states of sleep and anesthesia raises clinically relevant questions. For example, sleep deprivation enhances pain, worsens obstructive sleep apnea, impairs immune function, and contributes to cognitive decline. If a patient is sleep d...

To ARM or not to ARM?

Purposeful heading during a season does not influence cognitive function or balance in female soccer players.

Soccer participation, especially among females, is growing in popularity in the United States. Purposeful heading, an important soccer skill, has recently been scrutinized for safety reasons. The purpose of this study was to determine whether there was a relationship between purposeful heading and scores on cognitive function and balance in high school and collegiate female soccer players. Prio...
