Integration of adult generated neurons during epileptogenesis.
Adult generated neurons in the dentate gyrus become functionally integrated into the existing hippocampal circuit by forming synapses with mature neurons. It is now well established that seizure activity increases neural proliferation, but only recently has the fate of seizure-induced newborn neurons been examined. An emerging consensus proposes that newborn neurons are highly sensitive to thei...
متن کاملFunctional integration of newly generated neurons into striatum after cerebral ischemia in the adult rat brain.
BACKGROUND AND PURPOSE Ischemic injury can induce neurogenesis in the striatum. Those newborn neurons can express glutamic acid decarboxylase and choline acetyltransferase, markers of GABAergic and cholinergic neurons, respectively. The present study investigated whether these GABAergic and cholinergic new neurons could differentiate into functional cells. METHODS Retrovirus containing the EG...

today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
Functional Integration of Adult-Born Neurons
Over the past decade, it has become clear that neural stem cells in the adult mammalian brain continuously generate new neurons, predominantly in the hippocampus and olfactory bulb. However, the central issue of whether these new neurons participate in functional synaptic circuitry has yet to be resolved. Here, we use virus-based transsynaptic neuronal tracing and c-Fos mapping of odor-induced ...
متن کاملCapacity to maintain mental set in dementia.
Two experiments investigating the capacity to sustain mental set in dementia were conducted. Experiment 1 analyzed performance of a non-demented control group (NC), participants with Alzheimer's disease (AD) and participants with ischemic vascular dementia (IVD) on the Boston Revision of the Wechsler Memory Scale Mental Control subtest (MC). On simple tasks there were no between-group differenc...
