Olfaction: diverse species, conserved principles.

TL;DR: The author states that the present manuscript aims to provide a history of the field and some of the techniques used in its development, as well as some suggestions for further study, which are suggested by the authors.

TL;DR: A robotic platform designed for implementing and testing spiking neural network control architectures and a neuromorphic real-time approach to sensory processing, reward-based associative plasticity and behavioral control are presented.

TL;DR: Chemical ecology of sea cucumber reproduction focuses on the chemical communication and reproductive success of sea cucumbers. The chapter explores the role of chemical communication in various aspects of sea cucumber reproduction, including fertilization, aggregation, and synchrony.

TL;DR: Recent studies demonstrate that brain regions throughout the olfactory system are critically involved in forming and representing learned knowledge, and the role of olfactory areas in learning and memory, and their susceptibility to dysfunction in neurodegenerative diseases, necessitate further research.

TL;DR: This work has cloned and characterized 18 different members of an extremely large multigene family that encodes seven transmembrane domain proteins whose expression is restricted to the olfactory epithelium and is likely to encode a diverse family of odorant receptors.

TL;DR: Using a combination of calcium imaging and single-cell RT-PCR to identify odorant receptors (ORs) for odorants with related structures but varied odors, it is found that one OR recognizes multiple odorants and that one odorant is recognized by multiple ORs, but that different odorants are recognized by different combinations of ORs.

TL;DR: This first comprehensive analysis of the genome sequence of the Brown Norway (BN) rat strain is reported, which is the third complete mammalian genome to be deciphered, and three-way comparisons with the human and mouse genomes resolve details of mammalian evolution.

TL;DR: A genetic approach is developed to visualize axons from olfactory sensory neurons expressing a given odorant receptor, as they project to the Olfactory bulb, which provides direct support for a model in which a topographic map of receptor activation encodes odor quality in the ofactory bulb.
