Debilitating neurodegeneration due to brain injury or disease currently has limited treatment options and no cures. Endogenous repair mechanisms could provide targets for novel regenerative therapies. Drosophila melanogaster is a leading model for studies of neural development; however, this model has not been exploited to investigate the capacity of regeneration in the adult brain. This is primarily due to earlier studies demonstrating that adult Drosophila brains have limited mitotic activity and that neural progenitors undergo apoptosis during metamorphosis. We have developed and used a novel model of neural injury termed penetrating traumatic brain injury (PTBI) to investigate the capacity of neuroregeneration in adult central brains. Within 24 hours after injury, we observe a robust proliferative response and upregulation of neural progenitor genes. While there is some cell death post-PTBI, this is limited to early timepoints after injury; by 10 days, the amount of cell death is not significantly different from non-injured age-matched controls. Cell division continues out to 14 days post- injury, with the creation of new neurons and new glia. Using cell lineage-tracing techniques, we found that new neurons are generated by cells that had once expressed dpn; these dpn-expressing cells are not found in uninjured controls. Taken together, our data support the idea that there is a quiescent NB-like population of cells that is activated upon injury, specifically in young adult flies. The newly created cells are able to contribute to the overall regeneration of damaged brain tissue, particularly near the mushroom body. Indeed, while flies 2 days post-PTBI have locomotor defects and significantly different sleep profiles compared to uninjured controls, by 14 days post- PTBI, locomotor activity and sleep is restored back to normal levels. We find that other factors, including socialization and light, impact the ability of flies to recover and warrant further investigation. We anticipate that our model will allow us to further dissect the mechanisms by which this occurs and anticipate that these processes will have relevance to mammals, including humans.

The volume includes 75 papers which were presented at the Third International Conference on Intracerebral Hemorrhage, held in Rancho Mirage, California, in March 2010.

Translational Neuroscience offers a far-reaching and insightful series of perspectives on the effort to bring potentially revolutionary new classes of therapies to the clinic, thereby transforming the treatment of human nervous system disorders. Great advances in the fields of basic neuroscience, molecular biology, genomics, gene therapy, cell therapy, stem cell biology, information technology, neuro devices, rehabilitation and others over the last 20 years have generated unprecedented opportunities to treat heretofore untreatable disorders of the nervous system. This book provides a wide-ranging yet detailed sample of many of these efforts, together with the methods for pursuing clinical translation and assessing clinical outcomes. Among the topics covered are Alzheimer’s disease, Parkinson’s disease, stroke, multiple sclerosis, epilepsy, motor neuron disease, pain, inborn errors of metabolism, brain tumors, spinal cord injury, neuroprosthetics, rehabilitation and clinical trial design/consideration. Translational Neuroscience is aimed at basic neuroscientists, translational neuroscientists and clinicians who seek to gain a perspective on the nature and promise of translational therapies in the current era. Both students and established professionals will benefit from the content.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.

Brain aminergic pathways are organized in parallel and interacting systems, which support a range of functions, from homoeostatic regulations to cognitive, and motivational processes. Despite overlapping functional influences, dopamine, serotonin, noradrenaline and histamine systems provide different contributions to these processes. The histaminergic system, long ignored as a major regulator of the sleep-wake cycle, has now been fully acknowledged also as a major coordinator of attention, learning and memory, decision making. Although histaminergic neurons project widely to the whole brain, they are functionally heterogeneous, a feature which may provide the substrate for differential regulation, in a region-specific manner, of other neurotransmitter systems. Neurochemical preclinical studies have clearly shown that histamine interacts and modulates the release of neurotransmitters that are recognized as major modulators of cognitive processing and motivated behaviours. As a consequence, the histamine system has been proposed as a therapeutic target to treat sleep-wake disorders and cognitive dysfunctions that accompany neurodegenerative and neuroinflammatory pathologies. Last decades have witnessed an unexpected explosion of interest in brain histamine system, as new receptors have been discovered and selective ligands synthesised. Nevertheless, the complete picture of the histamine systems fine-tuning and its orchestration with other pathways remains rather elusive. This Research Topic is intended to offer an inter-disciplinary forum that will improve our current understanding of the role of brain histamine and provide the fundamentals necessary to drive innovation in clinical practice and to improve the management and treatment of neurological disorders.

This volume connects current ideas and concepts about sleep functions and circadian rhythms with the search for novel target-selective sleep-wake therapeutics. To do so, it provides a timely, state-of-the-art overview of sleep-wake mechanisms in health and disease, ongoing developments in drug discovery, and their prospects for the clinical treatment of sleep-disordered patients. It particularly focuses on the concept that sleep and wakefulness mutually affect each other, and the future therapeutic interventions with either sleep- or wake-promoting agents that are expected to not only improve the quality of sleep but also the waking behavior, cognition, mood and other sleep-associated physiological functions.
