We offer a theory of economic fluctuations based on intertemporal increasing returns: agents who have been active in the past face lower costs of action today. This specification explains the observed persistence in individual and aggregate output fluctuations even in the presence of i.i.d shocks, because individuals respond to the same shock differently(More)
The neuronal network controlling feeding behavior in the CNS of the mollusc Lymnaea stagnalis has been extensively investigated using intracellular microelectrodes. Using microelectrodes however it has not been possible to record from large numbers of neurons simultaneously and therefore little is known about the population coding properties of the feeding(More)
Oscillating neuronal circuits, known as central pattern generators (CPGs), are responsible for generating rhythmic behaviours such as walking, breathing and chewing. The CPG model alone however does not account for the ability of animals to adapt their future behaviour to changes in the sensory environment that signal reward. Here, using multi-electrode(More)
