Behavioral response is absent under the mating competition in rats (Rattus norvegicus)
Chu, Xi; Ågmo, Anders j (Journal article; Peer reviewed, 2019)Sexually receptive female rats normally copulate with several males during estrus, and multiple paternity is common. Sperm competition is therefore likely to occur. One response to competitive mating is to enhance sperm ... -
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 ... -
Revisiting the Labial Pit Organ Pathway in the Noctuid Moth, Helicoverpa armigera
KC, Pramod; Chu, Xi; Kvello, Pål; Zhao, Xin-Cheng; Wang, Gui-Rong; Berg, Bente Gunnveig (Peer reviewed; Journal article, 2020)Lepidopteran species detect CO2 via a specialized organ located on the peripheral segment of the labial palps, the labial palp pit organ (LPO). Based on tracing of LPO sensory neurons targeting one distinct antennal-lobe ... -
Spontaneous spiking activity in morphologically characterized neuron categories
Kymre, Jonas Hansen (Master thesis, 2017)Individual neurons can be characterized by their electrophysiological activity. Such characterizations have helped researchers investigate the functioning of individual neurons and neural networks consisting of distinct ... -
The Neural connections between the primary olfactory center and higher brain regions in the male moth : morphological and physiological properties of projection neurons and centrifugal neurons
Berge, Christoffer Nerland (Master thesis, 2018)In the insect brain, different types of neurons provide input and output to the primary olfactory center, the antennal lobe. The principal output neurons, projection neurons, convey odor information from the antennal lobe ...
