Consolidation of an extinction memory depends on the unconditioned stimulus magnitude previously experienced during training.

27 Jul 2009 Here, we examine the role of the magnitude of the unconditioned stimulus (US) during classical conditioning in consolidation processes after memory retrieval. We varied the US durations during training and we test the impact of these variations on ...

Tonically active neurons in the striatum differentiate between delivery and omission of expected reward in a probabilistic task context.

26 Jul 2009 Tonically active neurons (TANs) in the primate striatum are responsive to rewarding stimuli and they are thought to be involved in the storage of stimulus-reward associations or habits. However, it is unclear whether these neurons may signal the ...

Reconsolidation: maintaining memory relevance.

25 Jul 2009 The retrieval of a memory places it into a plastic state, the result of which is that the memory can be disrupted or even enhanced by experimental treatment. This phenomenon has been conceptualised within a framework of memories being reactivated ...

Direct comparisons of the size and persistence of anisomycin-induced consolidation and reconsolidation deficits.

22 Jul 2009 An issue of increasing theoretical interest in the study of learning is to compare the processes that follow an initial learning experience (such as learning an association between a context and a shock; memory consolidation processes) with those ...

Reciprocal patterns of c-Fos expression in the medial prefrontal cortex and amygdala after extinction and renewal of conditioned fear.

22 Jul 2009 After extinction of conditioned fear, memory for the conditioning and extinction experiences becomes context dependent. Fear is suppressed in the extinction context, but renews in other contexts. This study characterizes the neural circuitry ...

Morphine-induced suppression of conditioned stimulus intake: effects of stimulus type and insular cortex lesions.

21 Jul 2009 Intake of an unconditionally preferred taste stimulus (e.g., saccharin) is reduced by contingent administration of a drug of abuse (e.g., morphine). We examined the influence of insular cortex (IC) lesions on morphine-induced suppression of an ...

Pheromone-induced olfactory memory in newborn rabbits: Involvement of consolidation and reconsolidation processes.

20 Jul 2009 Mammary pheromone (MP)-induced odor memory is a new model of appetitive memory functioning early in a mammal, the newborn rabbit. Some properties of this associative memory are analyzed by the use of anisomycin as an amnesic agent. Long-term memory ...

Tyrosine phosphorylation of the 2B subunit of the NMDA receptor is necessary for taste memory formation.

20 Jul 2009 We aimed to test whether tyrosine phosphorylation of the NMDA receptor (NMDAR) in the insular cortex is necessary for novel taste learning. We found that in rats, novel taste learning leads to elevated phosphorylation of tyrosine 1472 of the NR2B ...

A neural computational model of incentive salience.

15 Jul 2009 Incentive salience is a motivational property with 'magnet-like' qualities. When attributed to reward-predicting stimuli (cues), incentive salience triggers a pulse of 'wanting' and an individual is pulled toward the cues and reward. A key ...
