1. Comunicação olfatória no roedor social Trinomys yonenagae (Caviomorpha: Echimyidae) / Olfactory communication in the social rodent Trinomys yonenagae (Caviomorpha: Echimyidae)
Vários aspectos do relacionamento entre mamíferos, como pareamento sexual e relações de grupo, requerem o reconhecimento de indivíduos. Sinais químicos são fundamentais nesse contexto, pois permitem a identificação individual e sexual. Roedores são animais que apresentam um senso olfatório muito desenvolvido e o empregam em sua comunicação socia

2. A imagem do cheiro: o paradoxo na publicidade de perfume
The current research approaches the comunicative modality we name: olfactory communication. We understand the perfume as a media form. We have investigated the history of the perfume in several civilizations and its use in the rituals. We have inserted some discoveries regarding the smell in the communication of the human being since their early age. As the

3. Analysis of chemical signals by nervous systems.
Intraspecific and interspecific communication and recognition depend on olfaction in widely diverse species of animals. Olfaction, an ancient sensory modality, is based on principles of neural organization and function that appear to be remarkably similar throughout the zoosphere. Thus, the "primitives" of olfactory stimuli that determine the input informati

4. Histamine directly gates a chloride channel in lobster olfactory receptor neurons.
Biogenic amines mediate many types of intercellular communication in multicellular organisms. Heretofore, little direct evidence has indicated that biogenic amines produce intracellular responses other than by triggering the enzymatic production of second messengers. Our electrophysiological studies of lobster olfactory receptor neurons now reveal that one b

5. Olfactory Receptor Database: a database of the largest eukaryotic gene family.
The Olfactory Receptor Database (ORDB) is a WWW-accessible database that stores data on Olfactory Receptor-like molecules (ORs) and has been open to the public since June 1996. It contains a public and a private area. The public area includes published DNA and protein sequence data for ORs, links to OR models and data on their expression, chromosomal localiz

6. Prediction of structure and function of G protein-coupled receptors
G protein-coupled receptors (GPCRs) mediate our sense of vision, smell, taste, and pain. They are also involved in cell recognition and communication processes, and hence have emerged as a prominent superfamily for drug targets. Unfortunately, the atomic-level structure is available for only one GPCR (bovine rhodopsin), making it difficult to use structure-b

7. Pannexins, a family of gap junction proteins expressed in brain
Database search has led to the identification of a family of proteins, the pannexins, which share some structural features with the gap junction forming proteins of invertebrates and vertebrates. The function of these proteins has remained unclear so far. To test the possibility that pannexins underlie electrical communication in the brain, we have investiga

8. Chemistry of sex attraction.
The chemical communication system used to attract mates involves not only the overt chemical signals but also indirectly a great deal of chemistry in the emitter and receiver. As an example, in emitting female moths, this includes enzymes (and cofactors, mRNA, genes) of the pheromone biosynthetic pathways, hormones (and genes) involved in controlling pheromo

9. Synaptic organization in the adult honey bee brain is influenced by brood-temperature control during pupal development
Recent studies have shown that the behavioral performance of adult honey bees is influenced by the temperature experienced during pupal development. Here we explore whether there are temperature-mediated effects on the brain. We raised pupae at different constant temperatures between 29 and 37°C and performed neuroanatomical analyses of the adult brains. An

10. Otx2 Induction of the Gonadotropin-releasing Hormone Promoter Is Modulated by Direct Interactions with Grg Co-repressors*
Hormonal communication between the hypothalamus, pituitary, and gonads orchestrates the development and regulation of mammalian reproductive function. In mice, gonadotropin-releasing hormone (GnRH) expression is limited to ∼1000 neurons that originate in the olfactory placode then migrate to specific positions scattered throughout the hypothalamus.
