Although pathological gambling is a prevalent disease, its neurobiological and psychological underpinnings are not well characterized. Various lines of research suggest aberrant dopaminergic function may lead to pathological gambling. For example, human imaging studies have revealed dopaminergic activation coinciding with the performance of gambling-related tasks. Furthermore, dopamine D2-type receptor deficiency facilitates gambling behaviors and dopamine receptor agonist treatments for Parkinson’s disease have been shown to increase patient vulnerability to gambling. Pathological gambling is often co-morbid with drug addictions, and exposure to drugs of abuse has been shown to enhance motivation to gamble. The |

activation of midbrain dopamine neurons, as well as their terminal projection fields, is involved with the development and maintenance of various addictions. Importantly, recent articles have demonstrated that repeated exposure to conditions of gambling-like uncertain reinforcement lead to enhanced drive to seek reward, potentially through increasing the incentive motivational value of conditioned cues. Signaling molecules other than dopamine may also influence reward-seeking behaviors in pathological gamblers. For example, stress-related alterations in glucocorticoid signaling may effect decision making and influence gambling behavior. Together, these findings suggest common pathways exist that mediate gambling, drug dependence, stress, and movement disorders, and that cross-reactivity between these ailments may potentiate disease symptomology. The goal of this Research Topic is to further our understanding of the neurobiological mechanisms underlying the development of pathological gambling. |

Sommario/riassunto |

Lithium ion batteries (LIBs) are efficient storage systems for portable electronic devices, electrical power grids, and electrified transportation due to their high-energy density and low maintenance requirements. After their launch into the market in 1990s, they immediately became |

the dominant technology for portable systems. The development of LiBs for electric drive vehicles has been, in contrast, rather incremental. There are several critical issues, such as an energy density, system safety, cost, and environmental impact of the battery production processes, that remain challenges in the automotive field. In order to strengthen the LiB's competitiveness and affordability in vehicle technology, the necessity of game-changer batteries is urgent. Recently, a novel approach going beyond Li batteries has become rapidly established. Several new chemistries have been proposed, leading to better performances in terms of energy density, long-life storage capability, safety, and sustainability. However, several challenges, such as a thorough understanding of mechanisms, cell design, long-term durability, and safety issues, have not yet been fully addressed. This book collects some recent developments and emerging trends in the field of "post-lithium" batteries, covering both fundamental and applied aspects of next-generation batteries |
