In the present study, the effects of intra-dorsal hippocampal (intra-CA1) injections of nitric oxide (NO) agents on muscimol state-dependent memory were examined in mice. A single-trial step-down passive avoidance task was used for the assessment of memory retrieval in adult male NMRI mice. Post-training intra-CA1 administration of a GABAA receptor agonist, muscimol (0.05 and 0.1 μg/mouse) dose...

this paper presents a hybrid technique for simultaneous estimation of parameter and function in inverse heat conduction problems. no prior information is used for the functional form of the heat flux in the present study. the scheme presented here is a combination of two different classical methods: the variable metric method (vmm) and gauss method (gm). the determination of the unknown thermal...

We investigate the retrieval phase diagrams of an asynchronous fully-connected attractor network with non-monotonic transfer function by means of a mean-field approximation. We find for the noiseless zero-temperature case that this non-monotonic Hopfield network can store more patterns than a network with monotonic transfer function investigated by Amit et al. Properties of retrieval phase diag...

Cognitive functions such as memory retrieval involve a combination of state- and item-related processes. State-related processes are sustained throughout a task (e.g., "retrieval mode" associated with ongoing goals), whereas item-related processes are transient and allied to individual stimuli (e.g., "retrieval success" associated with the recovery of information from memory). The present study...

the capability of sand constitutive models is remarkably improved by taking into account the effect of soil state in their formulations. in this study, it has been shown that considering the effect of soil state leads to better simulation of soil instability of shear banding type. to this aim, constitutive equations of a state dependent sand model are explained first. consequently, the general ...

In the context of irreversible dynamics, associating to a physical process its intuitive reverse can result be quite ambiguous task. It is standard choice define using Bayes' theorem, but, in general, this not optimal. work we explore whether it possible characterise an optimal map building from concept state retrieval maps. doing so, propose set principles that maps should satisfy. We find out...
