The NEI Audacious Goal Initiative (AGI; see https://www.nei.nih.gov/audacious) is to restore vision through regeneration of neurons and neural connections in the eye and visual system. Recent advances have identified molecules and signaling pathways that can either promote or inhibit regeneration of neurons in the visual pathway. These advances have led to significant axon growth in mouse optic-nerve crush and other regeneration models. The purpose of this Funding Opportunity Announcement (FOA) is to invite applications proposing to use discovery-based approaches to identify unknown factors critical to the regeneration of neurons, guiding their axons to targets, and making new functional connections. Future FOAs will focus on understanding the biological mechanisms through which these factors influence regeneration.

A central goal of the BRAIN Initiative is to understand how electrical and chemical signals code information in neural circuits and give rise to sensations, thoughts, emotions and actions. Available technologies for recording and manipulating neural circuit activity in human and animal experiments are not sufficient to accomplish this goal. Non-invasive technologies are low resolution and/or provide indirect measures such as blood flow, which are imprecise. Invasive technologies can provide information at the level of single neurons producing the fundamental biophysical signals, but they can only be applied to tens or hundreds of neurons, out of a total number in the human brain estimated at 85 billion. Previous BRAIN FOAs sought to develop novel technology (RFA-NS-15-003) or to optimize existing technology ready for in-vivo proof-of-concept testing and collection of preliminary data (RFA-NS-15-004). This FOA seeks applications for technology at an even earlier stage of development. It seeks new and untested ideas that are in the very earliest stages. The support provided might enable calculations, simulations, computational models, or other mathematical approaches for demonstrating that the signal sources and/or measurement technologies are theoretically capable of meeting the demands of large-scale recording or manipulation of circuit activity. The support might also be used for building and testing phantoms, prototypes, in-vitro or other bench-top models in order to validate underlying theoretical assumptions in preparation for future FOAs aimed at testing in animal models. Invasive or non-invasive approaches are sought that will ultimately enable or reduce the current barriers to large-scale recording or manipulation of neural activity, and that would be compatible with experiments in humans or behaving animals. Applications are encouraged from any qualified individuals, including physicists, engineers, theoreticians, and scientists, especially those no

The purpose of the U.S.-China Program for Biomedical Collaborative Research is to stimulate collaborative basic, translational, and clinical research between United States (U.S.)-based researchers and Chinese researchers in the areas of cancer, environmental health, heart disease, blood disorders, diseases of the eye and visual system, mental health, and neurological disorders. Partnering U.S. and Chinese investigators must work jointly to submit identical applications to NIH and National Natural Science Foundation of China (NSFC), respectively. U.S. investigators must respond to the announcement from NIH, including the Chinese application as an attachment, and Chinese investigators must respond to a separate funding announcement from NSFC, including the NIH application as an attachment.

A central goal of the BRAIN Initiative is to understand how electrical and chemical signals code information in neural circuits and give rise to sensations, thoughts, emotions and actions. While currently available technologies can provide some understanding, they may not be sufficient to accomplish this goal. For example, non-invasive technologies are low resolution and/or provide indirect measures such as blood flow, which are imprecise; invasive technologies can provide information at the level of single neurons producing the fundamental biophysical signals, but they can only be applied to tens or hundreds of neurons, out of a total number in the human brain estimated at 85 billion. Other BRAIN FOAs seek to develop novel technology (RFA-NS-17-003) or to optimize existing technology ready for in-vivo proof-of-concept testing and collection of preliminary data (RFA-NS-17-004) for recording or manipulating neural activity on a scale that is beyond what is currently possible. This FOA seeks applications for unique and innovative technologies that are in an even earlier stage of development than that sought in other FOAs, including new and untested ideas that are in the initial stages of conceptualization.

The purpose of this FOA is to stimulate development of translation-enabling models for evaluating survival and integration of regenerated photoreceptors (PRCs) and retinal ganglion cells (RGCs) in model systems that are closer to human visual anatomy, function and/or disease than current models. The development of these models, tools, devices, novel therapies and/or other resources is expected to provide a resource to vision researchers developing cell-replacement therapies for visual system diseases and disorders. This FOA seeks to develop models that emulate critical aspects of a human blinding disease that might be amenable to regenerative therapy. The model system might involve specific defects generated by transgenic gene insertion and/or deletion, gene editing, chemical/physical means, and/or other approaches to emulate characteristics of human disease or create defects amenable to cell-replacement therapy. Model systems using non-human primates or other cone-dominant species that are more representative of the anatomy and physiology of the human retina are highly encouraged. Other biological models are acceptable provided they meet the overall objectives of the FOA.

The BrightFocus Foundation provides research funds for U.S. and international researchers pursuing high-risk studies that illuminate areas for which there currently is little understanding, helping to bring to light crucial knowledge about Alzheimer's disease, glaucoma, and macular degeneration. The organization's mission is to save mind and sight by funding innovative research worldwide and by promoting better health through education. To that end, the foundation is accepting applications for its Alzheimer's Disease Research and National Glaucoma Research programs. 1) Alzheimer's Disease Research: Grants of up to $300,000 over three years will be awarded to researchers for innovative investigator-initiated research projects. The program is designed to give scientists the opportunity to develop the preliminary data necessary to be considered competitive for larger government or corporate types of sponsorship. Applications must be received no later than October 18, 2017. 2) National Glaucoma Program: Grants of up to $150,000 over two years will be awarded to researchers for innovative investigator-initiated glaucoma-related research projects. The program is designed to give scientists the opportunity to develop the preliminary data necessary to be considered competitive for larger government or corporate types of sponsorship. Typically these awards are made to junior investigators, or to more established investigators who are proposing particularly innovative research.

The Brain Research through Advancing Innovative Neurotechnologies (BRAIN) InitiativeSM is aimed at revolutionizing our understanding of the human brain. By accelerating the development and application of innovative technologies, researchers will be able to produce a new dynamic picture of the brain that, for the first time, will show how individual cells and complex neural circuits interact in both time and space. It is expected that the application of these new tools and technologies will ultimately lead to new ways to treat, cure, and even prevent brain disorders.
