Functional Characterization of the Gustatory Sensilla of Tarsi of the Female Polyphagous Moth Spodoptera littoralis

Frontiers in Physiology, 2018
Contact chemoreception is crucial for host plant choice selection in insects and is guided by input from gustatory receptor neurons, GRNs, housed in gustatory sensilla.

Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly

Insect Molecular Biology, EarlyView.
Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

Projection patterns of gustatory neurons in the suboesophageal ganglion and tritocerebrum of mosquitoes

, 2005
Mosquitoes are heavily dependent on gustatory information when feeding. Following the recent elucidation of the molecular basis of gustation in the malaria mosquito, we present a detailed study of primary central projections of gustatory receptor neurons

Transcriptional responses of Aedes aegypti chemosensory tissues in response to volatile DEET and citronella oil

Insect Molecular Biology, EarlyView.
Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).

Postnatal developmental changes in the laryngeal chemosensory cell clusters of rats

Journal of Anatomy, EarlyView.
Chemosensory cell clusters appeared in the rat larynx 2 days after birth and were already connected to afferent nerve fibers. Their number increased until 3 weeks of age, then stabilized while continuing to grow through the addition of new cells. Because their number reached a plateau around the time of weaning, their development may be linked to ...

Avoiding DEET through Insect Gustatory Receptors

, 2010
SummaryDEET is the most widely used insect repellent worldwide. In Drosophila olfactory receptor neurons (ORNs), DEET is detected through a mechanism employing the olfactory receptor, OR83b.

The Role of Cholecystokinin in Peripheral Taste Signaling in Mice

Frontiers in Physiology, 2017
Cholecystokinin (CCK) is a gut hormone released from enteroendocrine cells. CCK functions as an anorexigenic factor by acting on CCK receptors expressed on the vagal afferent nerve and hypothalamus with a synergistic interaction between leptin.

Dreaming conundrum

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Dreaming, a common yet mysterious cognitive phenomenon, is an involuntary process experienced by individuals during sleep. Although the fascination with dreams dates back to ancient times and gained therapeutic significance through psychoanalysis in the early twentieth century, its scientific investigation only gained momentum with the ...

Exploring the Association Between Complaints of Sensory Hypersensitivity and Sleep Disturbances After Acquired Brain Injury: A Cross‐Sectional Study

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep disturbances are prevalent after acquired brain injury and negatively affect quality of life. Sensory hypersensitivity may cause or exacerbate sleep disturbances, yet evidence on this relationship after acquired brain injury is lacking. The aim of this study was to investigate the hypothesised positive relationship between the severity ...

The pharyngeal taste organ of a blood-feeding insect functions in food recognition

BMC Biology
Background Obligate blood-feeding insects obtain the nutrients and water necessary to ensure survival from the vertebrate blood. The internal taste sensilla, situated in the pharynx, evaluate the suitability of the ingested food.
