In this paper we consider two major issues: conceptual–experimental approaches to the self, and the neuroanatomical substrate of the self. We distinguish content- and processed-based concepts of the self that entail different experimental strategies, and anatomically, we investigate the concept of midline structures in further detail and present a novel view on the anatomy of an integrated subcortical–cortical midline system. Presenting meta-analytic evidence, we show that the anterior paralimbic, e.g. midline, regions do indeed seem to be specific for self-specific stimuli. (...) We conclude that future investigation of the self need to develop novel concepts that are more empirically plausible than those currently in use. Different concepts of self will require novel experimental designs that include, for example, the brain’s resting state activity as an independent variable. Modifications of both conceptual and anatomical dimensions will allow an empirically more plausible account of the relationship between brain and self. (shrink)

Spontaneous activity levels prior to stimulus presentation can determine how that stimulus will be perceived. It has also been proposed that such spontaneous activity, particularly in the default-mode network (DMN), is involved in self-related processing. We therefore hypothesised that pre-stimulus activity levels in the DMN predict whether a stimulus is judged as self-related or not. Method: Participants were presented in the MRI scanner with a white noise stimulus that they were instructed contained their name or another. They then had to (...) respond with which name they thought they heard. Regions where there was an activity level difference between self and other response trials two seconds prior to the stimulus being presented were identified. Results: Pre-stimulus activity levels were higher in the right temporoparietal junction (RTPJ), the right temporal pole (RTP), and the left superior temporal gyrus in trials where the participant responded that they heard their own name than trials where they responded that they heard another. Conclusion: Pre-stimulus spontaneous activity levels in particular brain regions, largely overlapping with the DMN, predict the subsequent judgement of stimuli as self-related. This extends our current knowledge of self-related processing and its apparent relationship with intrinsic brain activity in what can be termed a rest-self overlap. (shrink)

Disorders of consciousness (DoC)—that is, unresponsive wakefulness syndrome/vegetative state and minimally conscious state—are debilitating conditions for which no reliable markers of consciousness recovery have yet been identified. Evidence points to the GABAergic system being altered in DoC, making it a potential target as such a marker.

Addressing the productivity challenge of climate technology (ClimTECH) firms and avoiding the “green trap” is crucial for decoupling economic growth from carbon emissions and achieving sustainable development. This study uses the establishment of green finance reform and innovation pilot zones as a quasi-natural experiment and employs a difference-in-differences model to explore the impact of green finance policies on the total factor productivity (TFP) of ClimTECH firms and its spillover effects. The results show that (1) Green finance policies significantly increase TFP, (...) especially in state-owned firms, firms that actively disclose environmental information, firms led by long-tenure CEOs, and those in regions with strong intellectual property protection. (2) The channel analysis shows that green finance policies enhance firms' TFP by easing financing constraints, encouraging green technology improvements, and improving capital allocation efficiency. (3) The spillover effect analysis shows that the TFP increase driven by green finance policies not only enhances firm value but also stimulates local green innovation and reduces regional carbon emissions. This research offers theoretical insights and policy implications for strengthening green finance frameworks and enhancing the environmental responsibility of ClimTECH firms. (shrink)
