We examined the involvement of the hippocampus in short-term changes in exploratory behaviour in an open field (Experiment 1) and experimental contexts (Experiment 2). In Experiment 1, rats with excitotoxic lesions of the hippocampus were more likely to revisit recently visited zones within the open field than were control rats. Similarly, in Experiment 2 rats with hippocampal lesions showed gr...

This study investigates the use of short-term memory for pitch recognition in a Western (12-tone) vs. a 10-tone equal temperament context. 10 subjects with at least one year of formal music and theory training participated in an experiment that consisted of two identical music listening tests (one per tuning system) in which they were trained to recall a reference tone and count the number of t...

Reconsolidation studies have led to the hypothesis that memory, when labile, would be modified in order to incorporate new information. This view has reinstated original propositions suggesting that short-term memory provides the organism with an opportunity to evaluate and rearrange information before storing it, since it is concurrent with the labile state of consolidation. The Chasmagnathus ...

Visual short-term memory plays a key role in guiding behavior, and individual differences in visual short-term memory capacity are strongly predictive of higher cognitive abilities. To provide a broader evolutionary context for understanding this memory system, we directly compared the behavior of pigeons and humans on a change detection task. Although pigeons had a lower storage capacity and a...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...

Introduction: The effects of cannabinoids (CBs) on synaptic plasticity of hippocampal dentate gyrus neurons have been shown in numerous studies. However, the effect of repeated exposure to cannabinoids on hippocampal function is not fully understood. In this study, using field potential recording, we investigated the effect of repeated administration of the nonselective CB receptor agonist WIN5...

considering the importance of the agriculture sector in iran, this study investigated factors affecting economic growth and development of the agriculture sector in iran over the period of 1967-2009 for short term and long term, using ardl model. the results showed that the ratios of public investment expenditure to the gdp for short-term and long term have positive impacts on the economic grow...

the short term imprisonments have been eliminated from the sentence system of many countries. it is said that since the objectives of sentences have not been met, the short term imprisonments have been eliminated. many of lawyers argue that lack of adequate opportunity for recognizing the personality of criminal (observation) and subsequently lack of enough time for reform and resocializing the...
