Biologically inspired computing which is a branch of natural computing is the field of investigation that draws upon metaphors or theoretical models of biological systems in order to design computational tools or systems for solving complex problems. Spiking neural P systems [2] (shortly called SN P systems) are parallel and distributed computing models inspired by the neurobiological behaviour...

We propose two control strategies for achieving desired firing patterns in a physiologically realistic model neuron. The techniques are powerful, efficient, and robust, and we have applied them successfully to obtain a range of targeted spiking behaviors. The methods complement each other: one involves the manipulation of only a parameter, the applied soma current, and the other involves the ma...

IT IS WELL-ESTABLISHED THAT the vast majority of information is carried through the brain by action potentials. Exactly how this information is embedded within the spike train, however, has been a topic of some debate. Potential codes fall roughly into three categories: rate, timing, and synergy. In a rate code, the only thing that matters is the number of spikes that occur in a particular inte...

We present a minimal spiking network that can polychronize, that is, exhibit reproducible time-locked but not synchronous firing patterns with millisecond precision, as in synfire braids. The network consists of cortical spiking neurons with axonal conduction delays and spike-timing-dependent plasticity (STDP); a ready-to-use MATLAB code is included. It exhibits sleeplike oscillations, gamma (4...

Sterile and fertile flowers are an important evolutionary developmental (evo-devo) phenotype in angiosperm flowers, playing important roles in pollinator attraction and sexual reproductive success. However, the gene regulatory mechanisms underlying fertile and sterile flower differentiation and development remain largely unknown. Viburnum macrocephalum f. keteleeri, which possesses fertile and ...

Cerebellar Purkinje cells produce two distinct forms of action potential output: simple and complex spikes. Simple spikes occur spontaneously or are driven by parallel fibre input, while complex spikes are activated by climbing fibre input. Previous studies indicate that both simple and complex spikes originate in the axon of Purkinje cells, but the precise location where they are initiated is ...
