This paper presents a robust place recognition algorithm for mobile robots. The framework pro-posed combines nonlinear dimensionality reduction, nonlinear regression under noise, and variationalBayesian learning to create consistent probabilistic representations of places from images. These gener-ative models are learnt from a few images and used for multi-class place recognition wh...

williams, watts, macleod and mathews' (1988) model of anxiety and depression leads to the prediction that anxious patients will show mood – congreuent implicit memory bias, while depressed patients will show mood-congruent explicit memory bias.although this prediction has been supported by some researchers (denny & hunt, 1992 mathews, moog, et al , 1989 watkins, et al, 1992), the reliabili...

introduction: the brain renin-angiotensin system (ras) has been reported having a pathological role in age-related impairment in learning and memory. therefore, angiotensin converting enzyme inhibitors (acei) are expected to have positive effects on memory. longtime treatment with captopril (an angiotensin converting enzyme inhibitor) significantly attenuates the age-related impairment in learn...

objective : in this study, the effects of estradiol valerate and raloxifenea selective estrogen receptor modulator; (serm) on morphine induced sensitization were examined in mice memory, according to the step-down passive avoidance task. method: the mice received morphine or estradiol and raloxifene for three days alone or in combination with morphine. after a drug free period of 5 days, the su...

memory impairment is one of the main features of post-traumatic stress disorder (ptsd),there are multiple studies in memory impairment and cognitive function such as memory in a variety of explicit memory, implicit, procedural, active, declarative, revermid ,working, visual, false and autobiographical. the methodology of systematic review were, meta-analyzes and controlled studies of sites med ...

Electroconvulsive therapy (ECT) is an efficient treatment for several neuropsychiatric disorders however a large number of patients develop memory impairment after ECT. Different studies both on animals and human suggest that vasopressin has positive effects on memory and improves cognitive functions. In this randomized, double-blind controlled clinical trial, 50 patients with psychiatric d...

background: the involvement of water-soluble carotenoids, crocins, as the main and active components of crocus sativus l. extract in learning and memory processes has been proposed. in the present study, the effect of crocins on sporadic alzheimer's disease induced by intracerebroventricular (icv) streptozocin (stz) in male rats was investigated. methods: male adult wistar rats (n = 90 and...

according to reports about 30-thousand people spent watching television had the impact on their memory and recall that the results showed no differences between men and women. the people who watched less than an hour a day did better at every memory function. as these contributors watched negative political ads, physiological responses indicated that their body was reflexively preparing to move...

memory is the cognitive ability that allows acquiring, store and recalling information. anterior thalamic dysfunction creates memory deficits in rats and humans. anterior thalamus forms a memory network in connection with the hippocampus. this connectivity profile proposes that ventrolateral and anterior thalamus may display a nexus between reminder and control functions, such as action or atte...

early life stress during fetal development has been hypothesized to predispose several neurological and psychiatric disorders in adulthood. the purpose of this study was to investigate the effect of maternal stress on the volume of granular cells, total number of dark neurons and also the distribution of glycol-conjugates and changes of terminal sugars in the dentate gyrus. pregnant sprague-daw...
