Conditional deletion of α-CaMKII impairs integration of adult-generated granule cells into dentate gyrus circuits and hippocampus-dependent learning.

New granule cells are continuously integrated into hippocampal circuits throughout adulthood, and the fine-tuning of this process is likely important for efficient hippocampal function. During development, this integration process is critically regulated by the α-calcium/calmodulin-dependent protein kinase II (α-CaMKII), and here we ask whether this role is conserved in the adult brain. To do t...

Functional convergence of developmentally and adult-generated granule cells in dentate gyrus circuits supporting hippocampus-dependent memory.

In the hippocampus, the production of dentate granule cells (DGCs) persists into adulthood. As adult-generated neurons are thought to contribute to hippocampal memory processing, promoting adult neurogenesis therefore offers the potential for restoring mnemonic function in the aged or diseased brain. Within this regenerative context, one key issue is whether developmentally generated and adult-...

Delayed development of adult-generated granule cells in dentate gyrus.

A substantial fraction of adult-generated granule cells in the dentate gyrus survive and integrate into the existing neuronal network. These newborn neurons must navigate the environment of the adult brain, a setting that is presumably less optimized for neuronal maturation compared with that in the developing brain. We used EGFP (enhanced green fluorescent protein) expression in newborn granul...

LIS1 deficiency promotes dysfunctional synaptic integration of granule cells generated in the developing and adult dentate gyrus.

Type I lissencephaly, a neuronal migration disorder characterized by cognitive disability and refractory epilepsy, is often caused by heterozygous mutations in the LIS1 gene. Histopathologies of malformation-associated epilepsies have been well described, but it remains unclear whether hyperexcitability is attributable to disruptions in neuronal organization or abnormal circuit function. Here, ...

Dendritic integration in hippocampal dentate gyrus granule cells

Hippocampal granule cells are critical relay stations to transfer spatial information from the entorhinal cortex into the hippocampus proper. Therefore, the integrative properties of the small-caliber granule cell dendrites were examined in this thesis, using a combination of dual somato-dendritic patch-clamp recordings and two-photon glutamate uncaging. These experiments revealed unusual integ...
