Abstract
Insects have sophisticated olfactory systems that enable them to detect and respond to complex exogenous chemical cues. The encoding mechanisms of these chemical signals have been studied both in their peripheral and central nervous systems (CNS). While various neuromodulators have been shown to play significant roles in olfactory processing within the antennal lobes of the brain, their roles in peripheral olfactory sensory systems, such as the antennae, are less understood. This review focuses on the role of serotonin (5-HT) receptor in the locust antenna, specifically the modulatory function of the serotonin receptor2 on odour inputs. We also review recent studies on the modulation of olfaction in the peripheral nervous systems of insects and discuss potential directions for future research on the role of neuromodulators in insect peripheral olfactory systems.
期刊介绍：
Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year.
The following 11 areas are covered by Current Opinion in Insect Science.
-Ecology
-Insect genomics
-Global Change Biology
-Molecular Physiology (Including Immunity)
-Pests and Resistance
-Parasites, Parasitoids and Biological Control
-Behavioural Ecology
-Development and Regulation
-Social Insects
-Neuroscience
-Vectors and Medical and Veterinary Entomology
There is also a section that changes every year to reflect hot topics in the field.
Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
