Additional evidence for intact appetitive trace conditioning in hippocampal-lesioned rats.

30 May 2009 Hippocampal lesions impair aversive trace conditioning but do not interfere with appetitive Pavlovian trace conditioning of the licking response (LR). This experiment examined whether learning to discriminate the events occurring in the home cage ...

Disruption of cerebellar cortical inhibition in the absence of learning promotes sensory-evoked eyeblink responses.

30 May 2009 Theories of cerebellar learning propose that alterations in synaptic plasticity resulting in decreases in cerebellar cortical inhibition and increases in sensory activation of interpositus nuclei underlie the development of adaptively timed ...

Mouse model of fragile X syndrome: behavioral and hormonal response to stressors.

30 May 2009 Fragile X syndrome, a form of mental retardation caused by inadequate levels of fragile X mental retardation protein (FMRP), is characterized by extreme sensitivity to sensory stimuli and increased behavioral and hormonal reactivity to stressors. ...

Delay eyeblink classical conditioning is impaired in Fragile X syndrome.

30 May 2009 The authors examined 400 ms delay eyeblink classical conditioning in 20 participants with Fragile X syndrome ages 17 to 77 years, and 20 age-matched, healthy control participants. The participants in the Fragile X group demonstrated impaired ...

Hippocampal theta-band activity and trace eyeblink conditioning in rabbits.

30 May 2009 The authors examined the relationship between hippocampal theta activity and trace eyeblink conditioning. Hippocampal electrophysiological local field potentials were recorded before, during, and after conditioning or explicitly unpaired training ...

A behavioral analysis of the role of CA3 and CA1 subcortical efferents during classical fear conditioning.

30 May 2009 It has been proposed that the hippocampus and subcortical structures interact during the processing of fear and anxiety-related information. It has been demonstrated that the subcortical efferents from CA3 and CA1 can be selectively disrupted ...

Voluntary physical exercise alters attentional orienting and social behavior in a rat model of attention-deficit/hyperactivity disorder.

30 May 2009 The effects of voluntary physical exercise on attentional function and social behavior were examined in male and female spontaneously hypertensive rats (SHR), a commonly used animal model of attention-deficit/hyperactivity disorder (ADHD). Rats in ...

Associative learning, acquired equivalence, and flexible generalization of knowledge in mild Alzheimer disease.

30 May 2009 BACKGROUND: Acquired equivalence is a phenomenon in which prior training to treat 2 stimuli as equivalent increases generalization between them. Previous studies demonstrated that the hippocampal complex might play an important role in acquired ...

Accounting for occurrences: an explanation for some novel tendencies in causal judgment from contingency information.

30 May 2009 Contingency information is information about empirical associations between possible causes and outcomes. In the present research, it is shown that, under some circumstances, there is a tendency for negative contingencies to lead to positive causal ...

Emotional valence and the functions of autobiographical memories: positive and negative memories serve different functions.

30 May 2009 Differences between positive and negative autobiographical memories are often explained with reference to hypothesized evolutionary functions. Generally, it has been proposed that autobiographical memory serves directive, self-, and social ...
