New Study Uncovers Surprising Truth About Brain Speed Limitations

In a groundbreaking study, researchers have measured how swiftly the human brain is capable of processing information, and the findings may not be as commendable as previously thought. According to the scientists, humans are only able to handle information at a rate of merely 10 bits per second, despite absorbing billions of bits from their sensory inputs, which include the eyes, ears, skin, and nose.

To clarify, a bit is recognized as the fundamental unit of data in computing, with a standard Wi-Fi connection typically managing around 50 million bits per second. The study found that during activities such as reading, writing, engaging in video games, and solving a Rubik’s cube, the brain operates at a sluggish pace of merely 10 bits per second, a pace deemed “exceptionally slow”.

Researchers from the California Institute of Technology embarked on this investigation to uncover the reasons behind this seeming contradiction, with their results published in the journal Neuron last week.

“This is an exceedingly low figure. At every moment, we are extracting just 10 bits from the trillion that our senses collect, utilizing these 10 to interpret our surroundings and make choices. This presents a paradox: What is the brain accomplishing as it filters through all this data?” stated neurobiologist Markus Meister, who contributed to the study.

What’s the explanation?

While there is no definitive answer, the researchers suggested that the slow processing speed of our brains could be attributed to necessity, or more accurately, the absence of it.

“Our ancestors selected an ecological niche where the pace of the world allowed for survival,” the study asserted. “In fact, the 10 bits per second are usually only necessary in extreme situations, while most of the time our environment transforms at a much slower tempo.”

The study indicated that further investigation into why our brains seem to focus on one line of thought at a time, rather than utilizing the vast amount of information gathered every second, is essential.

“Current knowledge does not align with the significant cognitive resources available, and no plausible explanation has been put forward to account for a neural bottleneck that necessitates single-threaded functioning,” the researchers further commented.

Additional research is warranted as over 85 billion neurons exist, with one-third specialized in high-level cognition and located in the cortex.
