Summary:
It has been shown in vivo that the changes in the average excitatory synaptic conductance are balanced with those of inhibitory ones in cortical and spinal cord neurons. Additionally, time-constant firing irregularity is achieved when the ratio of the excitatory and inhibitory activities is constant. In this paper, we show that such ratio may fluctuate with time under the condition of neural balances. Time-changeable neural balance enables neuron to assign wide range of statistical values, and may have a possible relationship with robust neural computation in the cortex.
