Identification of different antennal-lobe neuron categories;: a morphological and physiological study of second order neurons in the primary olfactory brain centre of the moth Heliothis virescens
Stav, Ingrid Vaagland (Master thesis, 2014)Olfaction is the sense of smell, first mediated by specialized sensory cells in the sensilla hair covering the moth antennae, projecting to the primary olfactory centre the antennal lobe. From this first synaptic level the ... -
Individual neurons confined to distinct antennal-lobe tracts in the heliothine moth: Morphological characteristics and global projection patterns
Ian, Elena; Zhao, Xin Cheng; Lande, Andreas; Berg, Bente Gunnveig (Journal article; Peer reviewed, 2016)To explore fundamental principles characterizing chemosensory information processing, we have identified antennal-lobe projection neurons in the heliothine moth, including several neuron types not previously described. ... -
Investigative anatomical mapping of the Helicoverpa armigera antennal lobe via anterograde labeling of olfactory sensory neurons from different antennal sections
Combs, Michael Joseph (Master thesis, 2022)Det kjemosensoriske systemet regnes som det eldste systemet fra et evolusjonært perspektiv, og det er godt representert i hele dyreriket. I de fleste organismer består den kjemosensoriske sansen av to systemer – henholdsvis ... -
Mapping CO2 sensitive neurons in a model preparation
Arnesen, Mari Reitstøen (Master thesis, 2017)The ability of animals to detect volatile molecules in their environment is universal, and in an evolutionary perceptive, ancient. In many species a contact with the chemical world through the sense of smell is crucial for ... -
Mapping neural networks linked to a higher olfactory center in a model brain
Kjos, Ida Camilla (Master thesis, 2016)The sense of smell provides important information about the surrounding environment, affecting a diverse set of behaviors in a wide range of animals. As a vital sense being importantly interconnected with learning and ... -
Mapping of Central Pathways for CO2 Information in the Brain of the Moth Heliothis virescens
Dahl, Ingrid Moe (Master thesis, 2013)The olfactory system is vital for insects in their ability to seek food, reproduce, and orientate. Information about different odors, produced by plants or conspecifics, elicits behavioral responses in the insects. Knowledge ... -
Mapping of contralateral projections in the central olfactory pathway in the moth species helicoverpa armigera and heliothosis virescens
Auran, Ola (Master thesis, 2016)Olfaction is phylogenetically the most primitive sense. It is also a sense that evokes a lot of feelings in us humans, from disgust to nostalgic childhood memories. Olfaction is primarily an ipsilaterally organized system ... -
Mapping of second order olfactory neurons and ventral-cord neurons; double-fluorescence labeling performed from the noctuid moth, Heliothis virescens
KC, Pramod (Master thesis, 2014)Detection of chemical stimuli from the external environment is performed by all living organisms. Of all senses, the chemical sense is the evolutionary oldest. Also, the neural system devoted to process chemosensory ... -
Mapping projection neurons originating from male-specific versus ordinary antennal lobe glomeruli in the central olfactory pathway of the moth Heliothis virescens
Lillevoll, Siri Corneliussen (Master thesis, 2013)Fylogenetisk sett, er de kjemiske sansene de eldste, og alle organismer har utviklet en evne til å detektere kjemisk stimuli fra det eksterne miljøet. Insekter har lange antenner med sensoriske luktenevroner som kan detektere ... -
Neural Organization of Olfactory Signal Pathways in a Small Model Brain
Fjærli, Hilde Hoel (Master thesis, 2010)The chemical sense is regarded as the oldest sense, and all organisms have evolved a mechanism in order to detect molecules in the environment. Among many other creatures, the moth depends fundamentally on chemical ... -

Neuronal architecture of the second-order CO2 pathway in the brain of a noctuid moth
Chu, Xi; KC, Pramod; Ian, Elena; Kvello, Pål; Liu, Yand; Wang, Guirong; Berg, Bente Gunnveig (Peer reviewed; Journal article, 2020)Many insects possess the ability to detect fine fluctuations in the environmental CO2 concentration. In herbivorous species, plant-emitted CO2, in combination with other sensory cues, affect many behaviors including foraging ... -
A novel major output target for pheromone-sensitive projection neurons in male moths
Chu, Xi; Heinze, Stanley; Ian, Elena; Berg, Bente Gunnveig (Peer reviewed; Journal article, 2020)Even though insects have comparably small brains, they achieve astoundingly complex behaviors. One example is flying moths tracking minute amounts of pheromones using olfactory circuits. The tracking distance can be up to ... -
Organization of the parallel antennal-lobe tracts in the moth
Kymre, Jonas Hansen; Chu, Xi; Ian, Elena; Berg, Bente Gunnveig (Peer reviewed; Journal article, 2022)The olfactory pathways of the insect brain have been studied comprehensively for more than 40 years, yet the last decade has included a particularly large accumulation of new information relating to this system’s structure. ... -
Processing of pheromone information in related species of Heliothine moths
Berg, Bente Gunnveig; Zhao, Xin-Cheng; Wang, Guirong (Journal article; Peer reviewed, 2014)In heliothine moths, the male-specific olfactory system is activated by a few odor molecules, each of which is associated with an easily identifiable glomerulus in the primary olfactory center of the brain. This arrangement ... -
