Almost all tests of spatial memory have been conducted in the laboratory, using mazes of different kinds, relying on food or escape as the motivation for performance. The main brain region involved in processing spatial information (in vertebrates) is the hippocampus, which varies in size in ...
Just as spatial cognition is not a single phenomenon but a complex of cognitive abilities, so too is memory composed of several systems organized in hierarchical levels, all mediated by different brain structures. As with other types of memory,spatial memorycan be classified as short (i.e., mi...
This brain region is comprised of several substructures—CA1, CA2, CA3, and the dentate gyrus (DG)—each with different functions in learning and memory40,41,42,43,44,45. We performed a deconvolution of the CA1 pyramidal layer and the dentate gyrus (DG) granule cell layer using a ...
The hippocampal brain regions were extracted for gene expression and neurotransmitters analysis. Treatment with embelin at the doses of 0.3 and 0.6 mg/kg significantly reversed the spatial memory impairment induced by CCH in rats. Embelin treatment has significantly protected synaptic plasticity ...
Recently, we published a method for examining working and reference memory in mice using a spatial version of the water radial-arm maze. Here we describe a... Lynn A Hyde a,Gordon F Sherman c,Victor H Denenberg a b - 《Brain Research》 被引量: 47发表: 2000年 Persistent spatial working...
Following killing, tissue samples were obtained from various brain regions known to contribute to learning and memory, and monoamine and metabolite levels were measured. Several changes were observed in response to both stress and estradiol. Most noteworthy, stress treatment decreased homovanillic acid ...

Although the hippocampus is probably the most significant brain region with regard to spatial learning and memory in birds and mammals, other brain structures also play a role. One of these is theperirhinal cortex, with which the hippocampus has close anatomical links. The perirhinal cortex appear...
The impairment to deploy attention is considered here as a bilateral covert attention deficit. Disorganized ocular exploration appears to be independent and is hypothesized to result from processes maintaining a salience map over time (spatial working memory) and especially across saccades. 展开 ...
For edema, improvements were 12.8% over the Spatial GNN and 7.3% over the Spectral GNN, highlighting its segmentation accuracy for each tumor sub-region. This superiority underscores the model’s potential in improving brain tumor segmentation accuracy, precision, and computational efficiency. Keywords...
