One leading hypothesis suggests that memories are stored in ensembles of neurons (or
'engram cells') and that successful recall involves reactivation of these ensembles. A logical …

Abstract Development of central nervous system (CNS) is regulated by both intrinsic and
peripheral signals. Previous studies have suggested that environmental factors affect …

Tremendous strides have been made in our understanding of the neurobiological substrates
of memory–the so-called memory “engram”. Here, we integrate recent progress in the …

Adult neurogenesis in the dentate gyrus of the hippocampus is highly regulated by a number
of environmental and cell-intrinsic factors to adapt to environmental changes. Accumulating …

Adult hippocampal neurogenesis has been implicated in cognitive processes, such as
pattern separation, and in the behavioural effects of stress and antidepressants. Young adult …

Sex differences are reported in hippocampal plasticity, cognition, and in a number of
disorders that target the integrity of the hippocampus. For example, meta-analyses reveal …

The predominant focus in the neurobiological study of memory has been on remembering
(persistence). However, recent studies have considered the neurobiology of forgetting …

Adult hippocampal neurogenesis is the process by which new functional neurons are added
to the adult dentate gyrus of the hippocampus. Animal studies have shown that the degree of …

While memories are often thought of as flashbacks to a previous experience, they do not
simply conserve veridical representations of the past but must continually integrate new …

Biological differences between males and females are found at multiple levels. However,
females have too often been under-represented in behavioral neuroscience research, which …
