Sommario/riassunto |

NASA maintains a planetary protection policy to avoid the forward biological contamination of other worlds by terrestrial organisms, and back biological contamination of Earth from the return of extraterrestrial materials by spaceflight missions. Forward-contamination issues related to Mars missions were addressed in a 2006 National Research Council (NRC) book, Preventing the Forward Contamination of Mars. However, it has been more than 10 years since back-contamination issues were last examined. Driven by a renewed interest in Mars sample return missions, this book reviews, updates, and replaces the planetary protection conclusions and |

recommendations contained in the NRC's 1997 report Mars Sample Return: Issues and Recommendations. The specific issues addressed in this book include the following: the potential for living entities to be included in samples returned from Mars; scientific investigations that should be conducted to reduce uncertainty in the above assessment; the potential for large-scale effects on Earth's environment by any returned entity released to the environment; criteria for intentional sample release, taking note of current and anticipated regulatory frameworks; and the status of technological measures that could be taken on a mission to prevent the inadvertent release of a returned sample into Earth's biosphere. |

Sommario/riassunto |
|
In the last decade Neuroscience has made a huge jump in experimental techniques as well as in developing theoretical concepts and analytic tools for studying emergent properties in large neuronal networks. These potentially bring us closer to understanding, in biological terms, the unique and fantastic capabilities of the Human brain to both create art and to enjoy it. The goal of the aforementioned Research Topic is to |
|
|
|

|
|
|
|
bring together the key experimental and theoretical research linking state-of-the-art knowledge about the Brain with the phenomena of Art. We plan a broad scope of topics for this unique volume, by inviting experts in vision, audition, movement/dance and cinema, and to also ask a few artists to contribute insights on their creative process. We are certain that such a volume is highly timely and is presently missing, and that it will be highly attractive to a wide community of brain researchers and for the community at large. Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review. |
