As we observed, this neuron type can fire tonically and persistently after the termination of a strong inhibition (DC pulse).
Outside this interval, for values of (frac{m_{G}^{P}}{m_{G}^{I}} < I_{1}), the frequency of neural activity decreases and may enter quiescence while for values of (frac {m_{G}^{P}}{m_{G}^{I}} > I_{2}), neural firing drastically and persistently increases leading to epileptiform activity in agreement with experiment [48].
In addition to these persistently elevated firing rate patterns, neurons which presumably are constituent members of working memory networks exhibit analogous inhibited (below baseline rate) firing patterns.
According to the learning rule introduced by Hebb [2], the synaptic connection between two neurons is strengthened if the firing of the presynaptic neuron is repeatedly and persistently paired with firing of the postsynaptic neuron.
If the United States, despite our warning, persistently lights the fire of a new war in Korea, it will meet with an irrecoverable, bitter, miserable defeat.
Citation: A drummer boy, 14 years of age, and severely wounded and exposed to a heavy fire from the enemy, he persistently remained upon the field of battle until he had reported to Gen. W. T. Sherman the necessity of supplying cartridges for the use of troops under command of Colonel Malmborg.
Fund managers rarely got fired, even if they performed persistently worse than their peers.
Fans have persistently called for the firing of the team's top management.
The origin of this assumption can be dated back to 1949 when Donald Hebb proposed his famous Hebbian learning rule: 'When an axon of cell A is near enough to excite cell B and repeatedly or persistently takes part in firing it, some growth process or metabolic changes take place in one or both cells such that A's efficiency as one of the cells firing B, is increased' [60].
Hebb proposed that connections between two neurons are strengthened when one neuron repeatedly or persistently takes part in firing the other neuron (presynaptic and postsynaptic activity being the two factors) [ 36], a proposition now known as Hebb's rule.
