Formation Of Branching Angles At Bifurcations Of Ant Trail Networks, Subash Kusum Ray
Theses
Ants form dendritic trail networks around the nest to search for and exploit food sources located at the periphery of the network. Studies found these trail networks to be very efficient for the ants in terms of time and energy, which later was found stored in the bifurcation angle (θ) of the branches of these trail networks. It has been observed, that bifurcations are symmetrical when moving from the nest to the food source, while are asymmetrical when moving back towards the nest. The mean bifurcation angles have been found to be 50° - 80° for networks radiating out from …

Translation And Transcription Are Required For Endogenous Bursting After Long Term Removal Of Neuromodulators, Stefanie Eisenbach
Theses
Motor pattern-generating networks depend on neuromodulatory inputs to regulate the network activity. The pyloric network of the Cancer borealis stomatogastric ganglion (STG), a rhythmic motor pattern-generating network, requires modulatory inputs to generate this activity. When neuromodulatory inputs are removed, the pyloric network falls silent. However, patterned pyloric activity recovers spontaneously in about 24 hours in organ culture. To determine if synthesis of new proteins are involved in the recovery of pyloric activity after prolonged elimination of neuromodulators, translation inhibitors are tested on the recovery process of pyloric activity in C. borealis. In vitro experiments are conducted; the STG is …
