Neurophysiological research has shown that auditory and motor systems interact during movement to rhythmic auditory stimuli through a process called entrainment. This study explores the neural oscillations underlying auditory-motor entrainment using electroencephalography. Forty young adults were randomly assigned to one of two control conditions, an auditory-only condition or a motor-only condition, prior to a rhythmic auditory-motor synchronization condition (referred to as combined condition). Participants assigned to the auditory-only condition (auditory-first group) listened to 400 trials of auditory stimuli presented every 800ms, while those in the motor-only condition (motor-first group) were asked to tap rhythmically every 800ms without any external stimuli...

Nicola Power
Major emergencies are extreme team decision making environments. They are complex, dynamic, high-stakes and fast paced events, wherein successful resolution is contingent upon effective teamwork. Not only do emergency teams coordinate at the intrateam level (e.g., police team), but they are increasingly required to operate at the interteam level (e.g., police, fire and ambulance teams). This is in response to the desire for networked and cost-effective practice and due to the evolving nature of modern threats, such as extreme weather events and terrorist attacks, which require a multi- rather than single-agency response...

BACKGROUND: In parallel to the introduction of mobile communication devices with high computational power and internet connectivity, high-quality and low-cost health sensors have also become available. However, although the technology does exist, no clinical mobile system has been developed to monitor the R peaks from electrocardiogram recordings in real time with low false positive and low false negative detection. Implementation of a robust electrocardiogram R peak detector for various arrhythmogenic events has been hampered by the lack of an efficient design that will conserve battery power without reducing algorithm complexity or ease of implementation...

Ronald J Janssen, Janaina Mourão-Miranda, Hugo G Schnack
Psychiatric prognosis is a difficult problem. Making a prognosis requires looking far into the future, as opposed to making a diagnosis, which is concerned with the current state. During the follow-up period, many factors will influence the course of the disease. Combined with the usually scarcer longitudinal data and the variability in the definition of outcomes/transition, this makes prognostic predictions a challenging endeavor. Employing neuroimaging data in this endeavor introduces the additional hurdle of high dimensionality...

BACKGROUND: A stress fracture (SF) is a highly debilitating injury commonly experienced in United States Army Basic Combat Training (BCT). Body fat (BF) may be associated with this injury but previous investigations (in athletes) have largely used SF self-reports and lacked sufficient statistical power. This investigation developed an equation to estimate %BF and used that equation to examine the relationship between %BF and SF risk in BCT recruits. METHODS: Data for the %BF predictive equation involved 349 recruits with BF obtained from dual-energy X-ray absorptiometry...

Hippocampal atrophy measures from magnetic resonance imaging (MRI) are powerful tools for monitoring Alzheimer's disease (AD) progression. In this paper, we introduce a longitudinal image analysis framework based on robust registration and simultaneous hippocampal segmentation and longitudinal marker classification of brain MRI of an arbitrary number of time points. The framework comprises two innovative parts: a longitudinal segmentation and a longitudinal classification step. The results show that both steps of the longitudinal pipeline improved the reliability and the accuracy of the discrimination between clinical groups...

On a Sunday afternoon almost six months ago, we were deeply moved by the news that our Krešimir is no longer with us. The sad news spread from Sarajevo with the speed only most horrible and saddest news can achieve. And everybody who was reached by these news wondered whether it was possible and whether it was true. Because our professor Kostović left us a day before his 48th birthday. Krešimir Kostović was born on the 16th October 1969 in Zagreb, where he completed primary and secondary education. He enrolled at the University of Zagreb School of Medicine in 1988, and got his medical degree in 1995...

Severe valvular regurgitation can lead to pulmonary hypertension, atrial fibrillation and heart failure. Vena contracta width is used to estimate the severity of the regurgitation. Parameters affecting visualization of color Doppler have a significant impact on the measurement. We propose a data-driven method for automated adjustment of color gain based on the peak power of the color Doppler signal in the vicinity of the vena contracta. A linear regression model trained on the peak power was used to predict the orifice diameter...

Visual motion is an ethologically important stimulus throughout the animal kingdom. In primates, motion perception relies on specific higher-order cortical regions. Although mouse primary visual cortex (V1) and higher-order visual areas show direction-selective (DS) responses, their role in motion perception remains unknown. Here, we tested whether V1 is involved in motion perception in mice. We developed a head-fixed discrimination task in which mice must report their perceived direction of motion from random dot kinematograms (RDKs)...
