Scientists have transplanted memory from one cochlea to another – what does this mean for people


These are some kind of fantastic dreams, put into practice:
a team of neuroscientists at UCLA “transplanted” memory from the nervous system to one
snails in the nervous system is different, reports DEITA.RU with reference to CNN.

To do this, the team repeatedly “trained” the snail
with an electric shock.

“We induced a very simple kind of memory in snails,
called sensitization, “said David Glantzman, a member of the Integrative
biology and physiology UCLA and lead author of the study.

He compares the sensitization and experience of an earthquake or
another physically sharp, dissonant event. “After that, you will be very
to be nervous, “he said.

Glanzmann and his team used a series of blows to the snails
with an electric shock. “As a result, their reflexes have improved significantly. If we
touch their skin, they will be very much reduced. ”

When the snails were in the right condition, the team extracted the RNA from
their nervous systems and transferred it to “untrained” snails.

“Twenty-four hours later we checked the reflexes of these
snails, and they showed the same reflexes as those who underwent
electric shocks, “Glantzman said.

Why snails?

It is no accident that this breakthrough was made with the help of
snails. Glentzman says that neuroscientists are studying the machinations of the snail’s brain on
for decades.

“I’m a reductionist in the approach to studying memory,” he said.
“The human brains are so complex … so the snails have many advantages.
Because they have relatively simple nervous systems. ”

And what belongs to the cochlea, evolutionarily, probably in
some kind refers to a person.

“Science is moving forward by first clarifying the simple
things, and then building something more complex, based on them, “- said
Glanzmann. “Many of the cellular mechanisms of cognition and memory that we
identify in all animals, were first observed in the cochlea. ”

What does this mean for people?

Memory transfer and transplantation are fascinating. But the fact that
it works on snails, does not mean that we will soon live in the realm of “Eternal
the radiance of pure reason. ” In fact, the application of this knowledge to people can
be much more practical and useful.

“We were able to transfer memory with the help of RNA,” – said
Glanzmann. “Therefore, think about human memory violations, such as
dementia, Alzheimer’s disease and PTSD; if we can identify
a certain part of the RNA, perhaps we can use this knowledge to
creation of new and more effective methods of treatment.

In other words, a better understanding of how memories
physically formed in the components of the nervous system (including the brain), can
lead to a better understanding of memory-related diseases and disorders. ”

Conclusions also challenge some popular
representations of how the memory is stored.
