Aging induces molecular, cellular and functional changes in the adult brain that drive
cognitive decline and increase vulnerability to dementia-related neurodegenerative …

Microglia are the resident macrophages of the central nervous system. Microglia possess
varied morphologies and functions. Under normal physiological conditions, microglia mainly …

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 …

The rodent hippocampus generates new neurons throughout life. This process, named adult
hippocampal neurogenesis (AHN), is a striking form of neural plasticity that occurs in the …

Synapses between engram cells are believed to be substrates for memory storage, and the
weakening or loss of these synapses leads to the forgetting of related memories. We found …

Neural stem cells (NSCs) generate new neurons throughout life in the mammalian brain.
Adult-born neurons shape brain function, and endogenous NSCs could potentially be …

There has been an explosion of new findings recently giving us insights into the involvement
of microglia in central nervous system (CNS) disorders. A host of new molecular tools and …

Adult hippocampal neurogenesis (AHN) drops sharply during early stages of Alzheimer's
disease (AD), via unknown mechanisms, and correlates with cognitive status in AD patients …

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 …
