Supervenience and Basic Christian Beliefs

A field-oriented interpretation of Whiteheadian societies of actual occasions, when used to explain the notion of "strong supervenience" as applied to the mind-brain problem, allows one to claim that not only higher-level properties such as consciousness but even higher-level entities such as the mind or soul are emergent from lower-level systems of neuronal interaction. Moreover, it also explains the preexistence of God to the world and Christian belief in eternal life with the triune God in a way that is impossible within the limits of a theory of strong supervenience.     

Antiaggressive and motor effects of the DA release inhibitor CGS 10746B

In the present study the effects of a wide range of doses of the dopamine release inhibitor CGS 10746B were evaluated in spontaneous activity and in aggressive behaviour using the paradigm of isolation‐induced aggression. The two higher doses (8 and 16 mg/kg) produced a decrease in spontaneous motor activity. Antiaggressive effects were observed after administration of doses from 4 mg/kg upwards. At this dose, CGS 10746B diminished threat and attack, and although an increase in immobility was observed, no impairment of other motor behaviours was presented. With higher doses, aggression was practically abolished but with a concomitant effect on many other behaviours. When animals were separated depending on their latency of attack, those that showed a long attack latency (LAL) presented a stronger response to 4 mg/kg than those that had a short attack latency (SAL), which were not affected in their aggression by this dose. We can conclude that presynaptic dopamine function is necessary for the normal expression of aggressive behaviours, since CGS 10746B reduces aggression at doses that do not affect spontaneous motor activity.

The structure of and changes to the life values of Japanese consumers

As the standard of living improves and the number of choices expands, consumer behavior shifts from meeting needs to realizing the specific life values of each consumer. A structural analysis of life values was performed to increase understanding of consumer behavior as a whole, so that effective marketing strategies can be prepared. The structural analysis of life values was conducted by plotting daily activities in an evaluation space, which was defined by "necessity,""attractiveness," and "ease of achievement," and also by factor analysis of these daily activities. Using this method, we measured the structure of the daily activities of Japanese consumers, and then examined the value structure of time-consuming activities, which our research suggests will be considered highly attractive in the future. Based on the results of the surveys, we discuss the development of the market for highly attractive activities and products. However, an improvement in life infrastructure is a prerequisite to realizing a market for highly attractive activities and products.     

Marital Conflict and Risk for Child Maladjustment over Time: Skin Conductance Level Reactivity as a Vulnerability Factor

Skin conductance level reactivity (SCLR) was examined as a longitudinal mediator and moderator of relations between parental marital conflict and psychopathology among children and young adolescents. Participants were 157 boys and girls (M age at T1 = 9.31 years; SD = 1.97); there was a 2-year lag between T1 and T2 assessments. At T1, participants' SCLR was assessed in response to lab challenges. Parents completed measures of aggressive marital conflict and child adjustment at T1 and T2. Supportive of moderation effects, T1 marital conflict interacted with T1 SCLR and gender in the prediction of changes in maladjustment. The link between marital conflict and increased internalizing and externalizing symptoms was stronger for girls with higher SCLR than girls with lower SCLR. Marital conflict predicted increased externalizing behaviors for boys with lower SCLR but not higher SCLR, although levels of externalizing behaviors were similar among boys with lower and higher SCLR especially at higher levels of marital conflict. Findings build on the literature by illustrating the importance of examinations of both family risk and youth biological vulnerability for the prediction of psychopathology.     

无意识活动与静息态脑能量消耗

静息态脑活动的研究关注个体在清醒、静卧、闭眼时脑的活动情况,大量实验证明静息状态下大脑仍进行着持续不断的信息加工活动,并且消耗大量能量。本文在阐述无意识活动特性以及总结静息态脑能量消耗研究的基础上,提出用无意识活动解释静息态脑能量消耗的观点,强调在研究无意识活动的心理意义的同时,还要研究无意识活动的神经机制及其生理表现。

Neural substrates of reduced walking activity after supratentorial stroke: A voxel-based lesion symptom mapping study

BackgroundMost stroke patients exhibit low levels of walking activity, a key component of secondary stroke prevention. The predictors of walking activity may be multifactorial and are thus far partially understood. We aimed to study the neuroanatomic correlates of low levels of daily walking activity following hemispheric stroke.MethodsIn this cross-sectional study, 33 community-dwelling stroke survivors (age: 63.9 ± 12.9 years; % female: 36.4%; NIHSS at admission: 3.3 ± 4.0) were prospectively recruited at least 3 months after a first ever, unilateral, supratentorial stroke confirmed by brain magnetic resonance imaging. Walking activity was measured by daily step counts (steps∙day⁻¹), recorded using an Actigraph GT3x+ triaxial accelerometer over 7 consecutive days. Voxel-based lesion-symptom mapping was performed to identify brain areas associated with walking activity following stroke.ResultsParticipants presented 4491.9 ± 2473.7 steps∙day⁻¹. Lower levels of walking activity were related to lesions of the posterior part of the putamen, of the posterior limb of the internal capsule and of the anterior part of the corona radiata. No cortical region was associated with walking activity.ConclusionsOur preliminary results identify subcortical neuroanatomical correlates for reduced walking activity following stroke. If confirmed, these results could serve as a rationale for the development of targeted rehabilitative strategy to improve mobility after stroke.     

Effects of the axis of rotation and primordially solicited limb of high level athletes in a mental rotation task

A recent set of studies has investigated the selective effects of particular physical activities that require full-body rotations, such as gymnastics and wrestling (Moreau, Clerc, Mansy-Dannay, & Guerrien, 2012; Steggemann, Engbert, & Weigelt, 2011), and demonstrated that practicing these activities imparts a clear advantage in in-plane body rotation performance. Other athletes, such as handball and soccer players, whose activities do require body rotations may have more experience with in-depth rotations. The present study examined the effect of two components that are differently solicited in sport practices on the mental rotation ability: the rotation axis (in-plane, in-depth) and the predominantly used limb (arms, legs). Handball players, soccer players, and gymnasts were asked to rotate handball and soccer strike images mentally, which were presented in different in-plane and in-depth orientations. The results revealed that handball and soccer players performed the in-depth rotations faster than in-plane rotations; however, the two rotation axes did not differ in gymnasts. In addition, soccer players performed the mental rotations of handball strike images slower. Our findings suggest that the development of mental rotation tasks that involve the major components of a physical activity allows and is necessary for specifying the links between this activity and the mental rotation performance.     

Beyond the FN: A spatio-temporal analysis of the neural correlates of feedback processing in a virtual Blackjack game

Studies using event-related brain potentials (ERPs) to examine feedback processing in gambling tasks have focused almost exclusively on components elicited between 200 and 500 ms after feedback over the frontal-central region of the scalp (i.e., P2, feedback negativity (FN), and P3a). In contrast, studies examining the functional neuroanatomy of feedback processing reveal activation in a distributed network that includes the anterior and posterior cingulate, the lateral and medial orbitofrontal cortex, the occipital cortex, and the basal ganglia. In the current study, we used ERPs in combination with spatial principal components-massive univariate analysis and distributed source analysis to examine the time course, topography, and neural generators of ERPs elicited in a virtual Blackjack game from 0 to 2000 ms after feedback was delivered. The ERP data revealed the P2–FN–P3a complex, as well as, broadly distributed transient and slow wave activity that was sensitive to the magnitude and valence of an outcome. The ERPs reflected activation in the anterior and posterior cingulate, in addition to the occipital, temporal and medial frontal cortices. These data demonstrate that ERPs can provide valuable insight into the timing of neural recruitment within a distributed cortical network during the first two seconds of feedback processing.
