background and objective: temporal lobe epilepsy (tle) usually leads to memory deficit. in this study, we tried to assess the effect of withania somnifera extract on the impaired learning and memory in the intrahippocampal kainate model of tle in the rat. materials & methods: male rats (n=32) were divided into sham, extract+sham, kainite, and kainite+extract. for induction of epilepsy, uni...

Background & Aims: Hypoxia is the most common cause of seizures in the neonatal period. Seizure induced by hypoxia cause permanent increases in excitability of neurons and by changing in activity and synaptic plasticity leads to memory impairment. Crocins (Crocus sativus L.) is a water-soluble carotenoid and is the most important active components of saffron. Most studies indicate that crocin h...

intracerebroventricular (icv) injection of streptozotocin (stz) in rats is followed by long-term and progressive deficits in learning, memory, and cognitive performance which is somewhat similar to sporadic alzheimer’s disease (sad). epidemiological studies suggest that non-steroidal anti-inflammatory drugs (nsaids) could delay or slow the clinical expression of sad. therefore, the beneficial e...

Previous research shows that people can use the cooccurrence of words and objects in ambiguous situations (i.e., containing multiple words and objects) to learn word meanings during a brief passive training period (Yu & Smith, 2007). However, learners in the world are not completely passive, but can affect how their environment is structured by moving their heads, eyes, and even objects. These ...

Active machine learning research shows that training of classifiers can be improved when the learning algorithm itself selects training data (e.g., choosing examples for which it is uncertain). Recent work with humans documents similar improvements whereby ”active” learners who can select their own training examples are faster at learning simple classification rules than ”passive” learners who ...

Background and Objective: Diabetes mellitus (DM) affects synaptic plasticity in the hippocampus, leading to impairments in learning and memory. L-carnosine, an endogenous dipeptide, is reported to exhibit anti-diabetic and antioxidant effects. Therefore, this study was designed to evaluate its effect on learning and memory in diabetic rats. Materials and Methods: In the present study, male Wis...

Background and Objective: Intracerebroventricular (ICV) injection of streptozotocin (STZ) causes cognitive impairment in rats. The beneficial effect of saffron main component, safranal was investigated on ICV STZ-induced learning, memory, and cognitive impairment in male rats. Materials and Methods: For this purpose, rats were injected with ICV STZ bilaterally, on days 1 and 3 (3 mg/kg). The ST...

  Abstract   Introduction: Diabetes mellitus accompanies with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. Considering the beneficial antidiabetic potential of Nigella sativum (NS ), this research study was conducted to evaluate the effect of chronic consumption of NS on learning and memory in diabetic rats using passive avoidance and Y-m...

gabapentin (gbp) is one of the new antiepileptic drugs (aeds) applied extensively in neurology and psychiatry. the advantage of new aeds includes newer mechanism of action, broad spectrum of anti-seizure effects, lesser drug interactions and fewer side effects. gbp is a cyclized analogue of gaba but it does not interact with gaba receptors, nor does it inhibit gaba uptake or prevent the degener...

In the passive learning paradigm, a learner learns purely through observing its environment. The environment is assumed to generate a stream of training data according to some unknown probability distribution. Passive learning techniques di er in the type of results they seek to produce, as well as in the way they generalize from observations. Common learning tasks are the clustering, classi ca...
