The first equation is for the evolution of the neurons state and the second is for the growth of axon tips.
In this case, the difference in discriminability is mainly determined by the free evolution of the model neurons.
The results indicated that there was differential gene expression between adult and fetal neurons, and the gradient patterns of gene expression contributed to the understanding of the evolution of neurons in the brain [117].
The voltage traces of the neurons A and B and the evolution of the plasticity variables of neuron B obtained from simulations are shown in Figs. 5a and 5c, respectively.
Similarly, we consider the flux flowing now through a state θ as formed of the drifting flux due to the continuous evolution of the phase of the neurons due to (13), and the flux determined by the phase shifting generated by the arrival of synaptic impulses: J ( t, θ ) = f q ( t, θ ) + σ ( t ) ∫ s θ q ( t, y ) d y, (18).

Identifying the mechanism of disappearance of RB cells might produce further evidence to understand the evolution of sensory neuron architecture.
The time evolution of the voltage of a spiking neuron is modelled by a stochastic process, V, given as solution to the following stochastic differential equation (SDE): d V ( t ) = ( μ − V ( t ) τ + A sin ( ω t ) ) d t + σ d W ( t ), t 0 = 0 ; V ( t 0 ) = v 0, t n = inf { t > t n − 1 : V ( t ) = v th } for n ≥ 1, { V ( t n + ) = v 0, J n = t n − t n − 1. (1).
This suggests that regulation of axonemal motor genes is an ancestral function of Foxj1/ fd3F, whereas regulation of retrograde transport was acquired later in the Drosophila lineage, coinciding with the emergence of distinct ciliary zones in the evolution of Ch neurons.
This is also associated with the so-called epigenetic memory including learning and association with emotional experiences (Bailey et al. 1996; Si et al. 2004) as well as an effect of genetic imprints with the potential to influence sexual orientation (Mustanski et al. 2005), maternal care (Champagne 2008), and the evolution of mirror neurons (Borenstein and Ruppin 2005).
