Neuroscience, from the past many years, had tried to understand the complexities of human brain and its working. They are often entangled in challenges posed by mood disorders, learning problems, insomnia, obesity and many more sufferings caused by brain dysfunctions.
In this very quest, Scientists at UC Irvine, led by Gary Lynch, professor of psychiatry and human behavior, have taken a major step - for the first time in the history of neurosciences in successfully visualizing the memory in its physical substrate.
Working with advanced microscopic techniques called restorative deconvolution microscopy, the team studied the changes associated with synapses in the hippocampus and appearance of LTP-related markers.
Long -term potentiation (LTP) is a physiological phenomenon closely related to memory storage. The UC Irvine team found that LTP marker appears during learning and there is change in synaptic structure.
UC Irvine team found that synaptic junctions in rats changed their shape on exposure to complex environment and learning to find a path. When these changes blocked by injecting drugs, rats found it difficult to learn.
This study and outcomes will pave a way for one of the great objective of life sciences: mapping the distribution of memory across the brain. Until today, researchers were facing obstacles in locating memory trances or ‘engrams‘ because there was no technique to tag the synapses and the changes related to their shape.
Now, the contents inside your brain and experiences of your daily life can be encoded in terms of synaptic connections as their physical substrate.
