Adult-born neurons grow more than their infancy-born counterparts

Neurons created as a result of adult neurogenesis mature for longer and grow larger than those created during infancy. Findings suggest adult-born neurons may have a more powerful function than those created during infancy and may play a critical role in neuroplasticity.

Alzheimer’s drug reverses brain damage from adolescent alcohol exposure

Donepezil, a drug routinely administered to slow cognitive decline in Alzheimer's disease, shows promise in treating damage caused to the brain by adolescent alcohol exposure. The drug reverses neuroinflammation and neuron damage in rats exposed to alcohol during adolescence.

Amygdala Neurons Increase as Children Become Adults; Except in Autism

A new PNAS study reveals typically developing children experience neurogenesis in the amygdala as they become adults. However, for those with autism, the amygdala loses neurons as they age.

An Ion Channel Differentiates Newborn and Mature Neurons in the Adult Brain

Researchers report newborn granule cells in the dentate gyrus become less excitable after three weeks. The loss of excitability is crucial for the functioning of mature neurons.

Astrocytes Control the Generation of New Neurons from Neural Stem Cells

Neuroscience researchers show how astrocytes control the generation of new neurons in the brain. “In the brain, astrocytes control how many new neurons are formed from neural stem cells and survive to integrate into the existing neuronal networks. Astrocytes do this by secreting specific molecules but also by much less understood direct cell-cell interactions with stem cells”, says Prof. Milos Pekny.
