GPSS (General Purpose Simulation System) is celebrating its 40 birthday this year. We recognize this notable birthday by assembling a panel of discussants consisting of some of the folks who have contributed significantly to GPSS and its use over the years. The panelists are Springer Cox (GPSS/PC and GPSS World), Jim Henriksen (GPSS/H and Proof Animation), Peter Lorenz (promoter of GPSS in Euro...

Steven Dakin and colleagues present a detailed analysis of the stimuli used in our study [1] revealing that our method of interpolation is associated with certain changes in the statistical properties of interpolated images. They argue that these changes might represent a possible source of the BOLD signal non-monotonicity that we observed in the primary visual cortex (V1). This finding is inte...

Previous research has provided evidence for a neural system underlying the observation of another person's hand actions. Is the neural system involved in this capacity also important in inferring another person's motor intentions toward an object from their eye gaze? In real-life situations, humans use eye movements to catch and direct the attention of others, often without any accompanying han...

BACKGROUND Conventionally, the pregnancy duration is accepted to be 280-282 days. Fetuses determined by ultrasound biometry to be small in early pregnancy, have an increased risk of premature birth. We speculate that the higher rate of preterm delivery in such small fetuses represents a pathological outcome not applicable to physiological pregnancies. Here we test the hypothesis that in low-ris...
