Serotonin alters decisions to withdraw in ®ghting cray®sh, Astacus astacus : the motivational concept revisited
The biogenic amine serotonin is thought to play an important role in aggression in many species, including man. This paper summarizes experimental approaches which attempt to link this neuromodulator with ®ghting in a cray®sh model for which the complex agonistic behavior is well characterized. Based on a quantitative analysis of ®ghting we demonstrate that the infusion of small amounts of sero...
متن کاملAction potential and sodium current in the slowly and rapidly adapting stretch receptor neurons of the crayfish (Astacus astacus).
Action potentials (APs) and sodium current from the slowly and the rapidly adapting stretch receptor neurons in the crayfish (Astacus astacus) were recorded with a two microelectrode voltage- and current-clamp technique. In the rapidly adapting neuron the APs had a duration of 3.2 +/- 0.2 ms (means +/- SE) and an amplitude of 55.2 +/- 1.5 mV. In the slowly adapting receptor neuron APs had a dur...
متن کاملTemporal Decision Trees or the lazy ECU vindicated
The automatic generation of diagnostic decision trees from qualitative models is a reasonable compromise between the advantages of using a modelbased approach in technical domains and the constraints imposed by on-board applications. In this paper we extend the approach to deal with temporal information. We introduce a notion of temporal diagnostic decision tree, in which nodes have a temporal ...
متن کاملChemical Communication in Lobsters
Lobsters are fascinating animals that use chemicals as messages regarding their sexual status, their standing in a social hierarchy, and whether they affiliate with or avoid conspecifics. This, plus their economic importance, makes them important models for the study of intraspecific chemical communication. Our chapter is an overview of these processes, including the types of interactions betwe...
متن کاملRational theory choice: Arrow undermined, Kuhn vindicated
In a recent paper, Samir Okasha presented an argument that suggests that there is no rational way to choose among scientific theories. This would seriously undermine the view that science is a rational entreprise. In this paper I show how a suitably nuanced view of what scientific rationality requires allows us to avoid Okasha’s conclusion. I go on to argue that making further assumptions about...
