Associative learning and the genetics of schizophrenia.

4 May 2009 Several well-validated susceptibility genes for schizophrenia have now been identified. We suggest that these genes can be divided into two broad classes. Those in the first class have direct effects on synaptic plasticity mediated through actions ...

Identification and integration of sensory modalities: neural basis and relation to consciousness.

3 May 2009 A key question in studying consciousness is how neural operations in the brain can identify streams of sensory input as belonging to distinct modalities, which contributes to the representation of qualitatively different experiences. The basis for ...

Effect of cerebellar reversible inactivations on the acquisition of trace conditioned eyeblink responses in guinea pigs: comparison of short and long trace intervals.

May 2009 The cerebellum has been proved to be essential for the acquisition of delay eyeblink conditioning, but its contribution to the acquisition of trace eyeblink conditioning (TEBC) has not been fully determined. In the present study, using chemically ...

Increasing memory capacity and reducing spurious states in neural networks by introducing coherent and collective firing.

29 Apr 2009 It is well known that higher-order Hopfield nets called multispin models can increase memory capacity to some extent by extending the direct product of spin states to more than second order. However, a group of neurons can then respond degenerately ...

Forgetting the unforgettable through conversation: socially shared retrieval-induced forgetting of September 11 memories.

29 Apr 2009 A speaker's selective recounting of memories shared with a listener will induce both the speaker and the listener to forget unmentioned, related material more than unmentioned, unrelated material. We extended this finding of within-individual and ...

[Reversible and irreversible stages of amnesia development after disruption of associative memory reactivation in snail]

29 Apr 2009 We found previously that the inhibition of NMDA glutamate receptors during food aversion conditioning reactivation initiated disruption of long-term memory. In this work the dynamics of amnesia development was investigated. MK-801 (NMDA receptor ...

Olfactory association learning and brain-derived neurotrophic factor in an animal model of early deprivation.

29 Apr 2009 Animal models can serve to explore neural mechanisms underlying the effects of stressful early experiences on behaviors supporting attachment. Neonatal rats primarily use olfaction for attachment, and Brain-Derived Neurotrophic Factor (BDNF) may be ...

Contextual memory and encoding strategies in young and older adults with and without depressive symptoms.

29 Apr 2009 OBJECTIVES: This study examines the role of depressive symptoms associated with age on contextual memory and how this association could impair the use of strategic instructions during encoding. METHOD: Young and older controls and older adults with ...

A landmark blocks searching for a hidden platform in an environment with a distinctive shape after extended pretraining.

29 Apr 2009 In the blocking phase of three experiments, rats had to find a submerged platform beneath a spherical landmark in one corner of a triangular pool. Prior to this treatment, they were required to find the platform relative to either a sphere above it ...

The search for symmetry: 25 years in review.

29 Apr 2009 It has been 25 years since the publication of Sidman et al.'s (1982) report on the search for symmetry in nonhuman animals. They attributed their nonhuman subjects' failure to the absence of some critical experiences (e.g., exemplar training, ...
