Brain Speed:  The Basics

What is brain speed? 

The time it takes to:

Capture information.

Process the information.

Respond to the information.

Brain HQ describes it as how effectively one can react to and remember events.  (Brain Speed Exercises, 20010)  Neuroscientist Geoffrey Kerchner defines it as the rate at which a human can take in a bit of new information, reach some judgment on it, and then formulate a response (Walker, 2014). Most experts, though, will agree that it is the speed of processing information.

This is a common activity used to assess brain trauma.  Give it a try and reflect on what is needed to do well on it.  


When you read the word, see how fst can you say the color it is written.

Try it again in Spanish.  Is it easier or more difficult?


Note: It could be easier to perceive the color of the word faster in a language you do not know because you are avoiding the extra step of trying to make sence of the word and then to say the color.

Brain HQ Exercises include Speeeeeed.

Improving the brain’s ability to see details in what is seen, heard, and felt is important in improving brain speed.

BrainHQ exercises are designed to increase the quantity of sensory information that the brain takes in and improves the quality of brain processing and recording of information. This creates a ripple effect in the brain, improving the higher functions of the brain (Brain HQ's Scientific Design Principles, 2010).

There are five exercises in the brain speed category. Let’s discuss why three of them might help (Merzenich, 2014): 

Hawk Eye:   Trains our visual precision and exercises our field of view, both of which help to determine how much information we can quickly capture.

Eye for Detail: Works out our working memory—our ability to hold what we see in mind long enough to move it to long-term memory for better recall later.

Sound Sweeps: By infusing sound into frequency sweeps, the exercise retrains our brains to recognize sounds quickly and accurately, helping us to understand what is said in the moment and create clear memories of what we hear.

Visual Sweeps:  A sight-based version of sound sweeps. We perceive and judge inward and outward motions that get faster and faster. Different types of sweeps activate different sets of brain cells (one group might respond to horizontal motion, while a different group responds to vertical motion). Parameters change in the activities to utilize the highest possible number of neurons.

Fine Tuning: This activity allows us to hear distinctions better. It uses sounds that can be confused to train the brain to hear the differences more quickly and clearly. It may mean that we don’t have to ask people to repeat themselves as often, and may help us to better remember what we have heard.

The BHQ Connection: Now explore the Brain Speed exercises on the BrainHQ website: Since you are a beginner in the BHQ class, you may not have seen all of the brain speed exercises yet. That’s fine, but go ahead and read about them all when you have time. It will help you to understand the exercises better when you do start them.

Let's Look at Brain Speed and How we Can Increase It

Why does brain speed slow?


White Matter & Neurons

Neurotransmitters Connect & Transmitters Released

A decrease in processing speed can result from decreased sensory input (associated with hearing loss and reduced visual acuity which can also be associated with aging). 

There can be a number of other reasons for a slower processing speed. They can include:

Diseases such as diabetes, smoking, high blood pressure or other vascular conditions which wear away affect the blood vessels which feed the white blood cells;

A neurogenetive illness, such as Alzheimer’s; 

Head trauma, such as a concussion; (Walker, 2014);

Fatigue;

Emotional struggles;

Depression and/or anxiety.

Characteristics of Challenges with Brain Speed


A person who has a slower brain processing speed will take longer to respond to questions and complete tasks.

A person might lose track of information and task requirements, and not be able to process complex information (such as following lengthy instructions and conversations). (What is processing Speed, 2010)

There can be problems in attention, memory, organization, language or executive functions.  For example, as brain processing speed decreases, a person may have difficulty controlling attention, unable to access stored knowledge and skills, and may develop unorganized thinking and processing.

A person may notice difficulties in shifting attention, memory tasks, and problem solving.

What can we do to improve our brain speed?

According to Psychology Today, there are habits that can improve cognitive function include (Bergland, 2014, Gehrke, 2021):

o      [Bacopa Monnieri (Brahmi plant extract)

o      L-theanine

o      Racetams

o      Artichoke extract

o      Ginseng

Mindfulness is a simple concept with powerful results. It has been tied to a  decrease in stress, an improvement in mood, better sleep and more.  Meditation is a technique that encourages mindfulness, working to increase calmness and relaxation, improving psychological balance and improving well-being.  Mindfulness is the ability to be fully present, aware of where we are and what we are doing, and not particularly reactive or overwhelmed by what is going on around us.

Although it is a natural process, it can also be cultivated in various ways, such as walking, seated, laying down and moving meditation. We can also add it in short pauses of our everyday life, or by merging meditation practice with other activities (like Yoga or sports).

Meditating takes no special skills.  It requires just to be aware and in the moment. It is done without judgment and uses curiosity, warmth and kindness. Meditation has been used for many years to help increase calmness, physical relaxation, cope with illness and more.

There are many types of meditation, but most have four elements in common:

Attention:

Attention involves turning the experiences to focus on what is happening in the moment. It directs awareness to your breath, your thoughts, the physical sensations in your body and the feelings that you are experiencing

Acceptance:

Acceptance involves observing the feelings and sensations without judgment. You merely note them and let them go.

How fast do we process information?

100 billion neurons X 200 firings per second X 1000 connections per firing

= 20 million billion calculations per second

The brain can make about 2 conscious calculations per second.

How accurate are these calculations?  New research suggests that the brain is actually much quicker than this.

The Transformative Power of Classical Music

Benjamin Zander has two infectious passions: classical music, and helping us all realize our untapped love for it - - and by extension, our untapped love for all new possibilities, new experiences, new connections.


Combine several things at once: Learning Line Dancing is a great way to learn new skills that will engage the body, the mind and improve processing speed in the brain.  Click on this fun video (left), or check out any of the many others on YouTube, to get started.



If you prefer something less strenuous, how about a game of bridge?  This is another Balboa Park activity, currently meeting virtually online.   For more information about virtual games visit the San Diego Bridge Academy website. 



Besides BrainHQ, there are other things you can try. For example, this is a yoga exercise which is used in schools to help children with learning disabilities focus. It is very simple, and takes less than 3 minutes. View this short video.

That's Fast!

A study, conducted by MIT researchers (Potter, 2014) used rapid serial visual presentation to determine the minimum time needed to view an image.  Researchers presented a series of six or 12 pictures at between 13 and 80 ms per picture to each person in the study.  Although the study was looking at the effectiveness of cuing (naming the picture just prior to or after viewing), the study confirmed that images could be processed in as low as 13 ms.

A YouTube video was created in 2006 which demonstrates rapid serial visual presentation with words.  Can you follow?  Click here:  https://www.youtube.com/watch?v=7i9fZvWyLfI

The study was important because it involved giving subjects faster and faster views of the images for shorter periods of time.  Researchers expected that there would be a rapid decline in performance as while the length of time that the subject saw each image approached 1/20 of a second, but it didn’t happen.  Researchers saw recognition at the quickest level (13 ms).  The results made the scientist theorize that the images continued to be processed even after they had been seen.  If the images had disappeared from memory after the 13 ms, people would not have been successful in remembering the image.   The brain needs to retain the information for at least 13 ms to be remembered (13 Milliseconds: The Incredible Speed at Which Your Brain Can Identify an Image, 2014).

This evidence suggests that training can improve the efficiency and speed of processing.  By doing the BrainHQ exercisers, and particularly the brain speed exercises, we can potentially improve our processing speed.
