Method–Image Analysis section. We have clarified that segments needed to be fully
impregnated by Golgi stain to be included for analysis. Method–Image analysis section. We …

The hippocampus is critically involved in spatial learning. Spatial training in adult rats, which
improved their spatial learning ability, increased the number of excitatory hippocampal CA1 …

Increases in the number and/or the size of dendritic spines, sites of excitatory synapses,
have been linked to different types of learning as well as synaptic plasticity in several brain …

Background Changes in synaptic structure and efficacy including dendritic spine number
and morphology have been shown to underlie neuronal activity and size. Moreover, the …

Sensory experience alters neuronal circuits, which is believed to form the basis for learning
and memory. On a microscopic level, structural changes of the neuronal network are …

In previous studies, we observed a transient increase in dendritic spine frequency in the
molecular layer of the dentate gyrus at 6h following passive avoidance training [O'Malley A …

Rats were trained in four different learning tasks including the Morris-water task, a T-maze
delayed nonmatch-to-sample task, a skilled unilateral reaching task, and a skilled bilateral …

Why memory is a particular target for the pathological changes in Alzheimer's Disease (AD)
has long been a fundamental question when considering the mechanisms underlying this …

Experiences influence the development of the central nervous system. Cognitive training
promotes changes in the structure of the brain, such as in its weight and number of cells, as …

The search for cellular correlates of learning is a major challenge in neurobiology. The
hippocampal formation is important for learning spatial relations. A possible long-lasting …
