How the great apes (Pan troglodytes, Pongo pygmaeus, Pan paniscus, Gorilla gorilla) perform on the reversed reward contingency task II: transfer to new quantities, long-term retention, and the impact of quantity ratios.

29 Apr 2008 We tested 6 chimpanzees (Pan troglodytes), 3 orangutans (Pongo pygmaeus), 4 bonobos (Pan paniscus), and 2 gorillas (Gorilla gorilla) in the reversed reward contingency task. Individuals were presented with pairs of quantities ranging between 0 and 6 ...

Abnormal ventromedial prefrontal cortex function in children with psychopathic traits during reversal learning.

29 Apr 2008 CONTEXT: Children and adults with psychopathic traits and conduct or oppositional defiant disorder demonstrate poor decision making and are impaired in reversal learning. However, the neural basis of this impairment has not previously been ...

A comparison of backward and forward spatial spans.

29 Apr 2008 The standard Corsi blocks task is frequently used to measure the capacity of visuospatial working memory, but the implications of the use of both forward and backward recall are still unclear. In the present study, we showed that the backward Corsi ...

Rewarded associative and instrumental conditioning after neonatal ventral hippocampus lesions in rats.

4 Apr 2008 Sprague Dawley rats were submitted to bilateral ventral hippocampus lesions 7 days after birth. This corresponds to the Lipska and Weinberger's procedure for modeling schizophrenia. The aim of the present work was to test the learning capacity of ...

The temporal locus of the one-target advantage in rapid aimed movements.

30 Mar 2008 The execution of a fast aimed movement takes less time when it is performed in isolation than when it is followed by a movement to a second target. The most recent explanation of this so-called one-target advantage (OTA) is the movement integration ...

Contextual control of inhibition with reinforcement: adaptation and timing mechanisms.

30 Mar 2008 Four experiments with rats studied the effects of switching the context after Pavlovian conditioning. In three conditioned suppression experiments, a large number of conditioning trials created "inhibition with reinforcement" (IWR), in which fear of ...

Social approach and repetitive behavior in eleven inbred mouse strains.

19 Mar 2008 Core symptoms of autism include deficits in social interaction, impaired communication, and restricted, repetitive behaviors. The repetitive behavior domain encompasses abnormal motoric stereotypy, an inflexible insistence on sameness, and ...

Spontaneous recovery of motor memory during saccade adaptation.

17 Mar 2008 It is possible that motor adaptation in timescales of minutes is supported by two distinct processes: one process that learns slowly from error but has strong retention, and another that learns rapidly from error but has poor retention. This ...

Neurotoxic lesions of the medial prefrontal cortex or medial striatum impair multiple-location place learning in the water task: evidence for neural structures with complementary roles in behavioural flexibility.

9 Mar 2008 This series of experiments assessed the effects of neurotoxic damage to either the medial prefrontal cortex or the medial striatum on the acquisition of multiple-location place learning in the water task. During training, normal subjects learn to ...

Learning-dependent, transient increase of activity in noradrenergic neurons of locus coeruleus during slow wave sleep in the rat: brain stem-cortex interplay for memory consolidation?

2 Mar 2008 Memory consolidation during sleep is regaining attention due to a wave of recent reports of memory improvements after sleep or deficits after sleep disturbance. Neuromodulators have been proposed as possible players in this putative off-line memory ...
