From synchronous neuronal discharges to subjective awareness?
For practical clinical purposes, as well as because of their deep philosophical implications, it becomes increasingly important to be aware of contemporary studies of the brain mechanisms that generate subjective experiences. Current research has progressed to the point where plausible theoretical proposals can be made about the neurophysiological and neurochemical processes which mediate perce...
متن کاملNeuronal communication within synchronous gamma oscillations.
The gamma-band oscillatory activity notably appears in the primary sensory and motor cortical areas. Because both sensory and motor responses are characterized by many static and dynamic variables, questions are raised regarding how cortical neurons manage to transmit analog information within the gammaoscillatory activity. Here, a possible way of communication among pyramidal neurons in the ga...
متن کاملEmergent Synchronous Bursting of Oxytocin Neuronal Network
When young suckle, they are rewarded intermittently with a let-down of milk that results from reflex secretion of the hormone oxytocin; without oxytocin, newly born young will die unless they are fostered. Oxytocin is made by magnocellular hypothalamic neurons, and is secreted from their nerve endings in the pituitary in response to action potentials (spikes) that are generated in the cell bodi...
متن کاملControlling neuronal sensitivity to synchronous input
Neurons in vivo are continuously bombarded by synaptic input—so how can they detect particular inputs against this background of synaptic activity? We study how modulating background synaptic input can change neuronal sensitivity to a subset of synchronized inputs. We 3nd that changes in net excitation or inhibition vary both the probability of detecting synchronous input and also the probabili...
متن کاملFast Graph Generation for Synchronous Processes
The automated analysis of concurrent systems requires that they are translated from a syntactic presentation into some semantic space. One common space of interpretation is transition systems[2, 4]. In particular situations it is possible to produce these transformations piecewise, but in general we need to produce the complete system graph in order to analyse it. Performing this task efficient...
