During neurodevelopment, the brain fabricates an incredible number of neurons which then migrate to specific parts of the brain. The development of new neurons is active all the way through … Continue Reading Study identifies how adult brain circuits regulate new neuron production.
It is known that neurons in the central nervous system of higher vertebrates are formed during embryonic development and that neurogenesis does not occur postnatally, except in the hippocampus. Buried … Continue Reading Researchers sucessfully make memories stronger and more precise during aging in mice.
Exercise is well-known for its cognitive benefits because it causes neurogenesis, the creation of new neurons, in the hippocampus, which is a key brain region for learning, memory and mood … Continue Reading Research refutes famous study, shows neurons created through exercise don’t erase old memories.
A neuron is an electrically excitable cell that processes and transmits information through electrical and chemical signals in the brain. These signals between neurons occur via synapses, which connect to … Continue Reading Study maps neurogenetics of dendritic growth and formation.
Nervous system injuries affect over 90,000 people every year, with spinal cord injuries alone estimated to affect 10,000 people each year. As a result of this high incidence of neurological … Continue Reading Researchers successfully control mitochondria to regenerate damaged neurons.
Compared to other mammals, humans have the largest cerebral cortex. A sheet of brain cells that folds in on itself multiple times in order to fit inside the skull, the … Continue Reading Researchers identify and map a previously unknown gene critical for human brain development.
Brazil is in the midst of an unprecedented epidemic of Zika virus (ZIKV), a flavivirus that is transmitted by mosquitoes and sexually, which was first detected in the country in … Continue Reading New research provides mechanism and evidence of how Zika virus causes microcephaly in newborns.
Infection and inflammation during pregnancy have been associated with adverse outcomes, such as preterm birth, abortion, and postnatal cognitive disorders. Yet how microbial products circulating in the maternal bloodstream affect … Continue Reading Study shows maternal bacterial infections trigger abnormal neurogenesis in fetal brain.
The human brain is home to many different types of neurons with their own genetic signature to define their function. These neurons are derived from progenitor cells, which are specialized … Continue Reading The ‘neuronal big bang’ is visualised for the first time.
The human nervous system is made up of an astonishing diversity of neurons. And yet only a very small number of proteins are needed to generate and determine the identity … Continue Reading Researchers identify a previously unknown regulatory mechanism of neurogenesis.
Neural stem cells generate new neurons throughout life in the mammalian brain. Neural stem cells are self-renewing, multipotent cells that generate the main phenotype of the nervous system. Stem cells … Continue Reading Researchers identify neuroprotective mechanism against stem cell aging.
A new study from researchers at the Douglas Institute and McGill University, suggests that the integration of new neurons in the adult brain is a phenomenon more generally compromised in … Continue Reading Human olfactory bulb neurogenesis study sheds light on depression.
The mission of neural stem cells located in the hippocampus, one of the main regions of the brain, is to generate new neurons during the adult life of mammals, including … Continue Reading Researchers validate microglia role in reducing neurogenesis due to epileptic seizures.
Newborn neurons generated from neural progenitor cells in a brain region called the hippocampus play an important role in learning and memory in adults. However, the molecular mechanisms that control … Continue Reading Researchers map epigenetic pathway of neurogenesis in the hippocampus.
Researchers at Karolinska Institutet have succeeded in explaining how stem cells in the brain change to allow one type of stem cell to produce different cell types at different stages. … Continue Reading First known molecular signalling control for neurogenesis identified.
