This study aimed to continue our characterization of finger strength and multi-finger interactions across the lifespan to include those in their 60s and older. Building on our previous study of children, we examined young and elderly adults during isometric finger flexion and extension tasks. Sixteen young and 16 elderly, gender-matched participants produced maximum force using either a single finger or all four fingers in flexion and extension.

BACKGROUND: Health-related Habits (HrH) are a major priority in healthcare. However there is little agreement on whether exercise, diet, smoking or dental hygiene are better described as lifestyles, habits or behaviors, and on what is their hierarchical relationship. This research is aimed at representing the basic concepts which are assumed to constitute the conceptual framework enabling us to interpret and organize the field of HrH.
Recent evidence suggests that DNA methylation changes may underlie numerous complex traits and diseases. The advent of commercial, array-based methods to interrogate DNA methylation has led to a profusion of epigenetic studies in the literature. Array-based methods, such as the popular Illumina GoldenGate and Infinium platforms, estimate the proportion of DNA methylated at single-base resolution for thousands of CpG sites across the genome. These arrays generate enormous amounts of data, but few software resources exist for efficient and flexible analysis of these data.
Humans excel at reciprocal altruism in which two individuals exchange altruistic acts to their mutual advantage. The evolutionary stability of this system depends on recognition of and discrimination against non-reciprocators, and the human mind is apparently specialized for detecting non-reciprocators. Here we investigate the neural response to non-reciprocation of cooperation by imaging human subjects with fMRI as they play an iterated Prisoner's dilemma game with two assumed human partners.
It has been claimed that (1) computer professionals should be held responsible for an undisclosed list of "undesirable events" associated with their work and (2) most if not all computer disasters can be avoided by truly understanding responsibility. Programmers, software developers, and other computer professionals should be defended against such vague, counterproductive, and impossible ideals because these imply the mandatory satisfaction of social needs and the equation of ethics with a kind of altruism.
Tag-based ethnocentric cooperation is a highly robust behavior which can evolve and prevail under a wide variety of conditions. Recent studies have demonstrated, however, that ethnocentrism can temporarily be suppressed by other competing strategies, especially in its early evolutionary stages.

EEG was registered in healthy volunteers before and after their entry into modeling (hypnotic) catalepsy. The brain activity recorded under standard electrode placement (the 10-20 international classification) was processed using a special computer program. The data obtained were digitally represented as sets of standard parameters of EEG patterns in 0,5-32 Hz diapason (alpha-, beta1-, beta2,-, theta-, delta-rythms). These parameters were compared under different functional tests particularly connected with the control of sensomotor brain activity.

The study investigated hypnosis-related electroencephalographic (EEG) coherence and power spectra changes in high and low hypnotizables (Stanford Hypnotic Clinical Scale) induced by a virtual reality hypnosis (VRH) induction system. In this study, the EEG from 17 participants (Mean age = 21.35, SD = 1.58) were compared based on their hypnotizability score. The EEG recording associated with a 2-minute, eyes-closed baseline state was compared to the EEG during a hypnosis-related state. This novel induction system was able to produce EEG findings consistent with previous hypnosis literature.
