New Neurons in Adult Brains Remodel Memory

New Neurons in Adult Brains Remodel Memory | Social Neuroscience Advances | Scoop.it
The brain is extremely dynamic, building and pruning connections in milliseconds with many different types of neuroplasticity simultaneously arising in large circuits all over the brain. The holy grail of neuroplasticity has been the creation of new brain cells in adults. Research looking for one cell in a region of the brain is much more difficult than a needle in a haystack. Despite, overwhelming odds, study shows new neurons arising in at least three, and possibly more, places in the adult brain—both humans and other animals.

Recent research shows that new neurons at least in the critical memory center of the hippocampus, are critical to learning and memory and rapidly become part of existing circuits. In fact, they remodel the circuit to take in new material in new ways. A previous post described that more than a thousand different types of neurons exist. Neurogenesis research shows that these new adult born neurons may be completely new types of cells with increased excitability, more widespread connections, a new window of opportunity, and increased neuroplasticity. New neurons in adult brains remodel memory circuits to make information more specific.

Shedding new light on the formation of emotional fear memories | RIKEN

Shedding new light on the formation of emotional fear memories | RIKEN | Social Neuroscience Advances | Scoop.it
Everyday events are easy to forget, but unpleasant ones can remain engraved in the brain. A new study published in the Proceedings of the National Academy of Sciences identifies a neural mechanism through which unpleasant experiences are translated into signals that trigger fear memories by changing neural connections in a part of the brain called the amygdala. The findings show that a long-standing theory on how the brain forms memories, called Hebbian plasticity, is partially correct, but not as simple as was originally proposed.

Shedding new light on the formation of emotional fear memories

Everyday events are easy to forget, but unpleasant ones can remain engraved in the brain. A new study published in the Proceedings of the National Academy of Sciences identifies a neural mechanism through which unpleasant experiences are translated into signals that trigger fear memories by changing neural connections in a part of the brain called the amygdala. The findings show that a long-standing theory on how the brain forms memories, called Hebbian plasticity, is partially correct, but not as simple as was originally proposed.
