Neurons in the rat hippocampus signal current location by firing in restricted areas called place fields. During goal-directed tasks in mazes, place fields can also encode past and future positions through journey-dependent activity, which could guide hippocampus-dependent behavior and underlie other temporally extended memories, such as autobiographical recollections. The relevance of journey-...

Diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. Therefore, this research study was conducted to evaluate time-dependent changes in passive avoidance and Y-maze performance in male diabetic rats. For this purpose, male Wistar rats were randomly divided into control and diabetic groups. For induction of di...

Substance dependency has been related to an impairment in executive functions and to a dysfunction of the frontal cortex. In this study we developed two experimental tasks, which are physically identical, to analyze whether substance-dependent individuals are impaired in shifting response patterns (stimulus response links) or preferences (stimulus outcome links). To increase the specificity of ...

abstract the present study examined the effect of genre-based tasks on efl learners' speaking performance and probed whether genre-based tasks may empower efl learners to perform better on speaking tests. a further concern of the study was to explore whether the effect of genre-based tasks on speaking ability of efl learners varied across different age groups, i.e. teenagers (13-16 years o...

the present study adopts the perspective that metacognitive strategy instruction is bound to occur inside the classroom especially on oral tasks. accordingly, the researchers investigated whether metacognitive strategy instruction prior to oral tasks was more successful than conventional ways in improving efl learners’ oral proficiency. to this end, 56 participants studying in a language school...

Gravicentric visual alignments become less precise when the head is roll-tilted relative to gravity, which is most likely due to decreasing otolith sensitivity. To align a luminous line with the perceived gravity vector (gravicentric task) or the perceived body-longitudinal axis (egocentric task), the roll orientation of the line on the retina and the torsional position of the eyes relative to ...

Language-induced asymmetry to single word reading has been well investigated in past research. Less known are the complex processes and related asymmetries occurring when a is compared with previous one, according specific tasks. To this end, we used paradigm based on 80 sequential pair comparisons three blocked tasks: phonological, semantic orthographical matching judgment. Participants had de...

Vehicular cloud (VC) is a promising technology for processing computation-intensive applications (CI-Apps) on smart vehicles. Implementing VCs over the network edge faces two key challenges: (C1) On-board computing resources of single vehicle are often insufficient to process CI-App; (C2) The dynamics available resources, caused by vehicles’ mobility, hinder reliable CI-App processing. This wor...
