1. Evolution and Development of the Onychophoran Head and Nervous System
Sammanfattning : Onychophorans are closely allied to the arthropods and possess a body organisation more similar to Middle Cambrian fossils than to recent arthropods. This means that onychophorans in some respects can be regarded as a model for the last common ancestor to both the Arthropoda and the Onychophora. LÄS MER
2. Neurons against Noise : Neural adaptations for dim light vision in hawkmoths
Sammanfattning : All animals perceive the world through their senses, which form the basis for their decisions and motor actions. However, when these all-important senses reach their limit and cease to provide reliable information, the animal’s survival is threatened. LÄS MER
3. Chemical signalling in the Drosophila brain : GABA, short neuropeptide F and their receptors
Sammanfattning : Gamma-aminobutyric acid (GABA) and short neuropeptide F (sNPF) are widespread signalling molecules in the brain of insects. In order to understand more about the signalling and to some extent start to unravel the functional roles of these two substances, this study has examined the locations of the transmitters and their receptors in the brain of the fruit fly Drosophila melanogaster using immunocytochemistry in combination with Gal4/UAS technique.

4. Neuropeptides Related to Tachykinins and Leucokinins in the Developing Nervous System of Insects
Sammanfattning : In insects more than 300 neuropeptides have been identified and these have been implicated in a vast range of functional roles. These peptides have been grouped into families based on amino acid sequence similarities. LÄS MER
5. Distribution and actions of insect tachykinin-related peptides
Sammanfattning : Tachykinin-related peptides (TRPs) have been identified in a number of invertebrates belonging to the mollusca, euchiurdea, crustacea and insecta. The TRPs are named after their sequence similarities and possible common evolutionary relationship to the vertebrate tachykinins. LÄS MER
