In particular, the history-dependence of ion channel dynamics has long been recognized as a single-cell substrate for transient memory [34] [38].
This property can be considered as a single-cell substrate for transient memory, or context-dependent information processing: depending upon the current context that the neuron "sees" through the subset of the network impinging on it in the immediate past, the same synaptic event can evoke a postsynaptic spike or just a subthreshold depolarization.
Molecular basis of such transient memory of a cold period during plant development has been recently described in other species.
Cholinergic blockade by scopolamine, a central muscarinic receptor antagonist, may produce transient memory impairment in healthy subjects, and it has been used as a neurochemical model of cognitive degeneration in aged individuals.
We unveil the relevance of transient memory that underlines the utility of the above mechanisms for intelligent knowledge management in artificial sensorimotor systems.
The capability of controlling reaction kinetics, making some reactions faster or slower than the others, gives rise to complex behaviors in diverse chemical and biological systems, for example as seen in the transient memory in bacterial chemotaxis29 and the oscillations in cell cycles30.
Loss of consciousness, headaches, transient memory loss, slowed cognition, ringing in the ears and nausea are just a few of the symptoms that may or may not be present at the time of an injury.
However, the total asymptotic memory is still somewhat less than the total transient memory (1.57 vs. 1.96 bits).
Short term, or transient, memory is stored by the system for some time, and then 'forgotten' (see Fig. 4a,d).
Likewise, the three-dimensional readout (Spo, AprE, OD600) shows no more transient memory than is found in the sporulation pathway (1.96 bits), its most retentive member.
In this case, the transient memory trace induced by the external stimulus would gradually wane as the neuron trajectory converges to the stochastic attractor corresponding to a given noise realization.
