There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement- guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation (...) of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making. (shrink)

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

There is an increasing interest in the possibility of using nudges to promote people's health. Following the advances in developmental biology and epigenetics, it is clear that one's health is not always the result of one's own choices. In the period surrounding pregnancy, maternal choice behaviour has a significant influence on perinatal morbidity and mortality as well as the development of chronic diseases later in life. One's health is thus a matter of one's own as well as one's maternal choices. (...) Therefore, self-regarding and other-regarding nudges should be considered as viable strategies to promote health. In this article, we introduce the concept of other-regarding nudges. We use the harm principle and the principle of beneficence to justify these other-regarding nudges. We conclude by stressing the importance of a fair assessment of expectations towards the nudgee, when determining whether a nudge is aimed at preventing harm or promoting a good. (shrink)

Nielsen's model presents a new isomorphic brain-mind viewpoint, according to which the sole dream generator is found in a REM-on (explicit or covert REM) mechanism. Such a model cannot explain the dreamlike activity during SWS (slow wave sleep), SO (sleep onset) and in the last period of sleep. Moreover the hypothesis contrasts with Solms's data, which show that dreaming is present also in case of destruction of the REM generator. [Nielsen; Solms].

The author clarifies the existential philosophy that is implicit in Kurt Goldstein's philosophy of organism (Goldstein, 1963; 1995). Situated in response to the growing trend that psychological phenomena are reducible to the nervous system, the author argues for the reverse: that the significance of nervous system activity can only be understood by viewing it as background to foreground performances. Like the organization of perception into meaningful figure-- ground Gestalts, the existential modes of embodiment, sociality, temporality, spatiality, and attunement are organized (...) together to accomplish foreground performances. It is only within this context that the activity of the nervous system may be understood as significant or insignificant. Speech is given as an example. The article concludes with a commentary on how the trend of reducing psychological phenomena to neurological phenomena has impaired our understanding of brain disorders and psychological disorders.

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates. BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observations our ’learner’ discovers an optimal evaporation ramp for BEC production. In contrast to previous work, our learner uses a Gaussian process to develop a statistical model of the (...) relationship between the parameters it controls and the quality of the BEC produced. We demonstrate that the Gaussian process machine learner is able to discover a ramp that produces high quality BECs in 10 times fewer iterations than a previously used online optimization technique. Furthermore, we show the internal model developed can be used to determine which parameters are essential in BEC creation and which are unimportant, providing insight into the optimization process of the system.

The purpose of this essay is to investigate and critically analyse some of the formative factors which led to the spiritual maturation of a leading Vīraśaiva saint, Basava. This inquiry focuses on a single event in the life of this great reformer of medieval times, i.e. his spiritual conflict leading to his rejection of the upanayana ceremony. The study will proceed through an investigation of the earliest and subsequent sources which veil the personality of Basava. The traditional view will be (...) challenged as one-sided. By critically comparing the sources, a more comprehensive and plausible account will be suggested. (shrink)

This dialogue is on the nature of thought and thinking. The five disputants are Socrates, an imaginary neuroscientist from California, an Oxford don from the 1950s, a Scottish post-doctoral student, and John Locke. The discussion takes place in Elysium in the late afternoon. They examine the idea that thinking is an activity of the mind or the brain, whether the medium of thought consists of words or ideas, whether thoughtful speech is speech accompanied by thought, whether thinking, i.e. reasoning and (...) inferring, is a process, and what is meant by the claim that ‘thinking is the last interpretation’. The dialogue ends when the protagonists go to dinner, but will be resumed after the meal. (shrink)
