Stability of Neuronal Networks with Homeostatic Regulation
Neurons are equipped with homeostatic mechanisms that counteract long-term perturbations of their average activity and thereby keep neurons in a healthy and information-rich operating regime. While homeostasis is believed to be crucial for neural function, a systematic analysis of homeostatic control has largely been lacking. The analysis presented here analyses the necessary conditions for sta...
متن کاملSupplementary Information: Stability of neuronal networks with homeostatic regulation
Here we 1) derive stability conditions for the network with a non-linear f/I curve, and 2) the tighter stability criterion which be obtained by considering only the slowest mode of the system. Qualitatively, for the 3-dimensional system a criterion exists based on the envelope of the non-linearity. For the full network, the criterion is based on the maximum slope of the non-linearity and this i...
متن کاملProblems with neuronal models in temperature regulation.
Neuronal models in temperature regulation are primarily considered explicit statements of assumptions and premises used in design of experiments and development of descriptive equations concerning the relationships between thermal inputs and control actions. Some of the premises of current multiplicative models are discussed in relation to presently available experimental evidence. The results ...
متن کاملCuriosity-driven reinforcement learning with homeostatic regulation
We propose a curiosity reward based on information theory principles and consistent with the animal instinct to maintain certain critical parameters within a bounded range. Our experimental validation shows the added value of the additional homeostatic drive to enhance the overall information gain of a reinforcement learning agent interacting with a complex environment using continuous actions....
متن کاملRegulation of dendritic development by neuronal activity.
Proper development of dendrites is essential for the establishment of neuronal circuitry. The elaboration of the dendritic tree is a highly dynamic and regulated process, which involves the formation of new branches as well as the maintenance or elimination of pre-existing branches. This review describes recent advances in our understanding of the molecular mechanisms of activity-dependent dend...
