The vertebrate brain continues to produce new neurons throughout life 1 , 2 , 3 , 4 , 5 , 6 , 7 ,
8 , 9 , 10 , 11 , 12 . In the rat hippocampus, several thousand are produced each day, many …

Thousands of hippocampal neurons are born in adulthood, suggesting that new cells could
be important for hippocampal function. To determine whether hippocampus-dependent …

The hippocampal formation generates new neurons throughout adulthood. Recent studies
indicate that these cells possess the morphology and physiological properties of more …

Dendritic spines are postsynaptic sites of excitatory input in the mammalian nervous system.
Despite much information about their structure, their functional significance remains …

During the past several years, evidence has accumulated suggesting a relationship between
newly born cells in the hippocampus and various types of learning and memory. However, …

The role of the hippocampal formation in learning and memory has long been recognized.
However, despite decades of intensive research, the neurobiological basis of this process in …

A group of rats was trained to escape low-intensity shock in a shuttle-box test, while another
group of yoked controls could not escape but was exposed to the same amount and regime …

It is usually assumed that stressful life events interfere with our ability to acquire new
information. However, many studies suggest that stressful experience can enhance processes …

Dendritic spines are sources of synaptic contact that can be altered by experience and, as
such, may be involved in memories for that experience. Here we tested whether the …

Exposure to restraint and brief intermittent tailshocks facilitates associative learning of the
classical conditioned eyeblink response in male rats. Based on evidence of sex differences in …
