Circadian Biology: Clocks within Clocks
A small cluster of approximately 20,000 neurons in the ventral hypothalamus provide the body with key time-keeping signals and drive circadian rhythms. This circadian clock exhibits surprisingly complex substructures, with inputs from the retina, and outputs to other brain structures. Rather little is known of the neurotransmitters involved, or their regulation.
متن کاملClocks within clocks: timing by coincidence detection
The many existent models of timing rely on vastly different mechanisms to track temporal information. Here we examine these differences, and identify coincidence detection in its most general form as a common mechanism that many apparently different timing models share, as well as a common mechanism of biological circadian, millisecond and interval timing. This view predicts that timing by coin...
متن کاملThe Hourglass of Emotions
Human emotions and their modelling are increasingly understood to be a crucial aspect in the development of intelligent systems. Over the past years, in fact, the adoption of psychological models of emotions has become a common trend among researchers and engineers working in the sphere of affective computing. Because of the elusive nature of emotions and the ambiguity of natural language, howe...
متن کاملOn the Hourglass Model
The Hourglass Model The hourglass model of layered systems architecture [1] is a visual and conceptual representation of an approach to achieving a design that supports a great diversity of applications and admits a great diversity of implementations. At the center of the hourglass model is a distinguished layer in a stack of abstractions that is chosen as the sole means of accessing the resour...
متن کاملNeural networks through the hourglass.
The effect of the synaptic plasticity on the dynamics of a large neural network is studied. Our approach is analytic but inspired by the data, both simulated and experimental. We explain formation of the small strongly connected assemblies within a dynamical network following Hebb's rule. Also, we find the conditions for the synchrony effect in the stochastic network in the absence of large syn...
