Identification of an Additional Periplanone Receptor Family Gene Preferentially Expressed in the Male Antennae of the American Cockroach Open
Periplaneta cockroaches use periplanone analogs as female sex pheromones to attract males. We previously identified two periplanone receptor genes, PameOR1 and PameOR2, in the American cockroach Periplaneta americana. Here, we report the i…

Sensory evidence for complex communication and advanced sociality in early ants Open
Advanced social behavior, or eusociality, has been evolutionarily profound, allowing colonies of ants, termites, social wasps, and bees to dominate competitively over solitary species throughout the Cenozoic. Advanced sociality requires no…

Interactive parallel sex pheromone circuits that promote and suppress courtship behaviors in the cockroach Open
Many animals use multicomponent sex pheromones for mating, but the specific function and neural processing of each pheromone component remain unclear. The cockroach Periplaneta americana is a model for studying sex pheromone communication,…

Cuticular hydrocarbon reception by sensory neurons in basiconic sensilla of the Japanese carpenter ant Open
To maintain the eusociality of a colony, ants recognize subtle differences in colony-specific sets of cuticular hydrocarbons (CHCs). The CHCs are received by female-specific antennal basiconic sensilla and processed in specific brain regio…

Single Sensillum Recording: An electrophysiological recording that directly reveal olfactory transduction mechanisms in insects Open
昆虫は,特に発達した嗅覚神経系を備えており,匂い情報を利用して種内でコミュニケーションを取り,天敵から身を守るだけでなく,匂い情報から環境状況をも適切に判断することができる。近年,昆虫の嗅覚受容関連遺伝子について解析が急速に進む中,非モデル生物でも嗅覚受容関連遺伝子の報告が盛んに行われている。このような遺伝子の機能解析には嗅感覚細胞からの電気生理学的記録が欠かせない。しかしながら,昆虫嗅覚神経系からの電気生理学実験を展開する研究室が世界的にも少なくなってきている。 本稿では…

Silencing the odorant receptor co-receptor impairs olfactory reception in a sensillum-specific manner in the cockroach Open
Summary: Insects detect odors via a large variety of odorant receptors (ORs) expressed in olfactory sensory neurons (OSNs). The insect OR is a heteromeric complex composed of a ligand-specific receptor and the co-receptor (ORco). In this s…

Magnetic Resonance Imaging as a Novel Method for Elucidating Sediment Burrow Structures and Functions Open
Burrow structures produced by various benthic animals in sediments are important components of aquatic ecosystems, allowing the circulation of interstitial water via ingress of fresh bottom water into the burrows upon feeding and intraburr…

Social behavior, neuroimmune markers and glutamic acid decarboxylase levels in a rat model of valproic acid-induced autism Open
Autism is a complex neurodevelopmental disorder characterized by impaired social communication and social interactions, and repetitive behaviors. The etiology of autism remains unknown and its molecular basis is not yet well understood. Pr…

Quantitation Error in <sup>1</sup>H MRS Caused by B<sub>1</sub> Inhomogeneity and Chemical Shift Displacement Open
CSD and inhomogeneity of reception sensitivity cause amplitude modulation along the direction of chemical shift on the spectra, resulting in a quantitation error. This error may be more significant at higher B0 field where CSD a…

Two Parallel Olfactory Pathways for Processing General Odors in a Cockroach Open
In animals, sensory processing via parallel pathways, including the olfactory system, is a common design. However, the mechanisms that parallel pathways use to encode highly complex and dynamic odor signals remain unclear. In the current s…

Investigation of defect detectability for extreme ultraviolet patterned mask using two types of high-throughput electron-beam inspection systems Open
Defect detectability using electron-beam (EB) inspection for an extreme ultraviolet (EUV) mask was investigated by comparing a projection electron microscope (PEM) and a scanning electron microscope (SEM) inspection system. The detectabili…
