Olfactory learning in the honeybee was investigated using the conditioned proboscis extension reflex on restrained individuals. We compared, under the same experimental conditions, the most commonly used conditioning procedures, i.e. 1 trial, 3…

The transcription factor CREB (cAMP response element binding protein) is required for the switch from short-term to long-term synaptic plasticity and from short-term to long-term memory. Its activity is regulated by the cAMP-dependent signalling…

Long-term potentiation (LTP) is generally divided into two phases, early (E-) and late (L-) LTP, of which only L-LTP is thought to depend on protein synthesis. Here we report that E-LTP can also be dependent on protein synthesis at higher levels of…

Animals learn not only about stimuli that predict reward but also about those that signal the omission of an expected reward. We used a conditioned inhibition paradigm derived from animal learning theory to train a discrimination between a visual…

Neural connections between the mushroom body (MB) and other protocerebral areas of the honeybee's brain were studied with the help of cobalt chloride and Golgi staining methods. Focal injections of cobalt ions into the alpha-lobe neuropil of the MB…
-
Learning of new information is transformed into long-lasting memory through a process known as consolidation, which requires protein synthesis. Classical theory held that once consolidated, memory was insensitive to disruption. However, old memories…

Translation of eukaryotic mRNAs is generally initiated by the scanning ribosome mechanism. This can be downregulated by high affinity protein binding to cap-proximal RNA motifs. Translation can also be regulated by short open reading frames within…

The morphological basis of the persistent synaptic plasticity that underlies long-term habituation and sensitization of the gill withdrawal reflex in Aplysia californica was explored by examining the fine structure of sensory neuron presynaptic…
-
Many computer graphics applications require high-intensity numerical simulation. We show that such computations can be performed efficiently on the GPU, which we regard as a full function streaming processor with high floating-point performance. We…

It has recently been pointed out that current density functionals are inaccurate for computing stereoelectronic effects and energy differences of isomerization reactions and isodesmic reactions involving alkanes; this has been interpreted as an…
-
Changes in the patterns of gene expression are widely believed to underlie many of the phenotypic differences within and between species. Although much emphasis has been placed on changes in transcriptional regulation, gene expression is regulated…
-
The persistence of synaptic potentiation in the hippocampus is known to depend on transcription and protein synthesis. We report here that, under regimes of reduced protein synthesis, competition between synapses for the relevant intracellular…

When A+ B+ training was conducted in the absence of CD+ trials. A further failure to observe abnormally strong responding during AB was found in Experiment 3 for which the training trials with A+ B+ CD+ were accompanied by trials in which C and D…
-
A new density functional (DF) of the generalized gradient approximation (GGA) type for general chemistry applications termed B97-D is proposed. It is based on Becke's power-series ansatz from 1997 and is explicitly parameterized by including damped…

The phosphorylation and the binding to DNA of the nuclear transcription factor, cyclic adenosine 3',5'-monophosphate (cAMP) response element-binding protein (CREB) are conserved key steps in the molecular cascade leading to the formation of…
