Nitric oxide affects short-term olfactory memory in the antennal lobe of Manduca sexta.

Nitric oxide (NO) is thought to play an important neuromodulatory role in olfaction. We are using the hawkmoth Manduca sexta to investigate the function of NO signaling in the antennal lobe (AL; the primary olfactory network in invertebrates). We have found previously that NO is present at baseline levels, dramatically increases in response to odor stimulation, and alters the electrophysiology ...

Contribution of different taste cells and signaling pathways to the discrimination of "bitter" taste stimuli by an insect.

Animals can discriminate among many different types of foods. This discrimination process involves multiple sensory systems, but the sense of taste is known to play a central role. We asked how the taste system contributes to the discrimination of different "bitter" taste stimuli in Manduca sexta caterpillars. This insect has approximately eight bilateral pairs of taste cells that respond selec...

Discrimination Training with Multimodal Stimuli Changes Activity in the Mushroom Body of the Hawkmoth Manduca sexta

BACKGROUND The mushroom bodies of the insect brain play an important role in olfactory processing, associative learning and memory. The mushroom bodies show odor-specific spatial patterns of activity and are also influenced by visual stimuli. METHODOLOGY/PRINCIPAL FINDINGS Functional imaging was used to investigate changes in the in vivo responses of the mushroom body of the hawkmoth Manduca ...

Insect cardioactive peptides. I. Distribution and molecular characteristics of two cardioacceleratory peptides in the tobacco hawkmoth, Manduca sexta.

Using an in vitro heart bioassay, the pharmacological and biochemical properties of two cardioactive peptides derived from neural tissues of the moth, Manduca sexta, were analysed. Gel filtration of ventral nerve cords (VNC) from pharate adults identified two cardioacceleratory peptides (CAP1 and CAP2) with apparent molecular weights of 1000 and 500 Da, respectively. Both CAPs were localized to...

Characterizing psychophysical measures of discrimination thresholds and the effects of concentration on discrimination learning in the moth Manduca sexta.

What is the spatial and temporal nature of odor representations within primary olfactory networks at the threshold of an animal's ability to discriminate? Although this question is of central importance to olfactory neuroscience, it can only be answered in model systems where neural representations can be measured and discrimination thresholds between odors can be characterized. Here, we establ...
