The ability to remember sounds, and manipulate them in our minds, is incredibly important to our daily lives. New research is shedding light on how sound memory works in the brain, and is even demonstrating a means to improve it.

Scientists previously knew that a neural network of the brain called the dorsal stream was responsible for aspects of auditory memory. Inside the dorsal stream were rhythmic electrical pulses called theta waves, yet the role of these waves in auditory memory were until recently a complete mystery.

Researchers applied transcranial magnetic stimulation (TMS) at the same theta frequency to the subjects while they performed specific memory related tasks, to enhance the theta waves and measure the effect on the subjects’ memory performance.

They found that when they applied TMS, subjects performed better at those memory tasks. This was only the case when the TMS matched the rhythm of natural theta waves in the brain. When the TMS was arrhythmic, there was no effect on performance, suggesting it is the manipulation of theta waves, not simply the application of TMS, which alters performance. (1)

Mapping the brain. But not your brain…

Synchronizing with the cosmos.

It seems important.

But it is actually the other way around.

Not being in sync is what requires effort.

And we are trying too hard for that every day.

Every single moment we get out of sync.

Every day we destroy our connection with the cosmos.

Memories, illusions, arrogance...

Stop trying so hard and watch the cosmos aligning with you.

You do not need any special tools to boost your memory.

The only thing you need to do is to let go.

And just remember, that you don’t need to remember…
