Ways To Boost Your Neurogenesis

You can grow new brain cells. Here’s how | Sandrine Thuret

It was long thought that the brain cells you were born with, were your only stock for your whole life. Any changes in your brain were down solely to neuroplasticity â neural networks adapting through new connections or neural pruning. However, a relatively modern finding in neuroscience is that you grow new brain cells, a process called neurogenesis. This even occurs into old age.

Like with neural pruning, if new neurons arenât put to use theyâll likely die off. But if they are involved in some kind of effortful learning, or activities which demand concentration over an extended period of time, then they can be kept long term. This emphasizes the importance of learning in the growth of our brains throughout our lives.

Something few people are aware of, is that new neurons in adult brains are actually more plastic and have increased excitability. For this reason itâs thought they can play a special role in improving cognitive rehabilitation outcomes for conditions such as brain injury or stroke.

More recent science is showing that rates of neurogenesis are affected by our lifestyles. In fact there are many ways being discovered to boost the growth rates of new neurons, so letâs take a look at 5 of them here.ââ

What Is Nerve Growth Factor

Nerve Growth Factor was the first neurotrophin to be isolated and studied, and its discovery has opened the door to new understanding of neurogenesis.

NGF was first identified by Italian scientist Rita Levi-Montalcini, who was awarded the 1986 Nobel Prize for Medicine for her research.

NGF has been extensively studied and it is now known to play a crucial role in both encouraging neurogenesis and in maintaining the health and efficiency of the human neural network as a whole.

It;promotes the differentiation of neural stem cells and promotes their development into neurons and improves memory;and cognition thanks to its;neuroprotective and repair capabilities.

NGF has been shown to enhance both spatial memory and recent memory, and it also promotes;long-term memory formation.

Growing New Neurons In Adulthood

Its now generally accepted that adult neurogenesis takes place in two specific areas of the brain. New neuron growth occurs in the dentate gyrus, a substructure within the hippocampus, and in the subventricular zone, which is located within the walls of the lateral ventricle in the forebrain.

New neurons are produced by the division of neural precursor cells, sometimes referred to as neural stem cells. These early stage cells have the potential to become either neurons or support cells.

The exact stimulation that makes neural precursor cells become neurons is still being studied, but the discovery of Nerve Growth Factor; established widespread acceptance that neurotrophins, proteins secreted by support cells called astrocytes, are a primary factor in encouraging precursor cells to proliferate and mature into neurons.

  • Taurine is a free amino acid that is vital in slowing key age-accelerating processes, particularly in the central nervous and cardiovascular systems.
  • Laboratory studies show that taurine can achieve what was once thought to be impossiblestimulate new growth and connections of brain cells, which raises the real possibility for restoration of youthful brain function in older adults.
  • Taurine levels decrease with age and with metabolic and neurological disease.
  • Supplementation with taurine, in both animal and human studies, demonstrates the age-decelerating effects of this amino acid.
  • Laboratory studies reveal dramatic improvements in cognition and memory in taurine-supplemented animals, and suggest that human supplementation might slow or reverse changes seen in Parkinsons disease.
  • Taurine supplementation boosts cardiac function and reduces arterial stiffness, both contributors to early death from heart disease and stroke.
  • Those with metabolic syndrome also stand to gain from taurine supplements, which substantially reduce that syndromes negative impacts on cardiovascular risk.

Scientists used to think that your brain stopped growing new cells once you reached adulthood. Happily, current research shows that this conventional wisdom simply isnt true! As you get older, you can continue to grow new brain cells and even reverse some of the natural brain cell loss that occurs with age. To encourage your brain to grow new cells, try adopting healthy habits like exercising regularly and doing stress-relieving activities. You can also protect your old brain cells by staying away from tobacco, limiting alcohol use, and managing health conditions such as high blood pressure and mood disorders.

Habits That Help You Regrow Brain Cells

Its no secret that our brains tend to slow down as we age. After the age of 25, we start to naturally lose brain cells. The good news is, scientists have discovered that you can grow new brain cells throughout your life. There are several habits you can adopt to promote the growth of new cells and keep your brain as sharp as ever.

Here are nine habits that help you regrow brain cells:

When Damaged The Adult Brain Repairs Itself By Going Back To The Beginning

University of California – San Diego
When adult brain cells are injured, they revert to an embryonic state, say researchers. In their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.

When adult brain cells are injured, they revert to an embryonic state, according to new findings published in the April 15, 2020 issue of Nature by researchers at University of California San Diego School of Medicine, with colleagues elsewhere. The scientists report that in their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.

Repairing damage to the brain and spinal cord may be medical science’s most daunting challenge. Until relatively recently, it seemed an impossible task. The new study lays out a “transcriptional roadmap of regeneration in the adult brain.”

“Using the incredible tools of modern neuroscience, molecular genetics, virology and computational power, we were able for the first time to identify how the entire set of genes in an adult brain cell resets itself in order to regenerate. This gives us fundamental insight into how, at a transcriptional level, regeneration happens,” said senior author Mark Tuszynski, MD, PhD, professor of neuroscience and director of the Translational Neuroscience Institute at UC San Diego School of Medicine.

Use Mitochondrial Support Nutrients

For optimal brain health, I also recommend that you support your mitochondrial health. Mito Support was designed to support the function of the mitochondria, which is the powerhouse of your cell and the key cellular health.

It is a blend of nutrients, nutraceuticals, botanicals, and Krebs cycle intermediates designed to support efficient mitochondrial metabolism and energy production for increased vitality. It supports brain health, cognition, mental health, and healthy energy levels.; Supporting your mitochondria is a key principle for brain regeneration.;;

Getting Into Ketosis From Time To Time

Under the regular circumstances, most peoples body creates energy by breaking down glucose from dietary carbohydrates. However, when your body doesnt receive enough glucose supply, it turns to dietary or stored body fat for energy. These fats are converted in the liver into ketones that enter your mitochondria inside your cells to be turned into energy.

This process of ketosis helps to enhance autophagy, reduce inflammation, improve mitochondrial biogenesis, improve brain health, and increase mental sharpness. The best way to experience ketosis is through the combination of the keto diet and intermittent fasting.;

I am not saying you have to follow a ketogenic diet all the time, you can vary your nutrition, but actively working to get into ketosis from time to time is extremely beneficial for brain regeneration.;To learn more about ketosis, I recommend this article, and to learn more about how the keto diet improves brain health, read this one.

How To Increase Brain Cell Production With Your Diet

Researchers have discovered some unexpected ways that diet affects brain cell regeneration.

Its not just what you eat, but how much you eat and how often you eat that matters as well.

Eating fewer calories and/or eating less often can help grow new brain cells.

Calorie restriction has been linked to;increased neurogenesis.

This seems to work by decreasing inflammation and increasing BDNF.

Intermittent Fasting

Another trick for increasing neurogenesis with food is to practice intermittent fasting.

This involves increasing the time between meals, up to 16 hours.

Its not as hard as it sounds since you can be asleep half of those hours.

So, having dinner at 6:00 pm and breakfast the next day at 10:00 am qualifies as intermittent fasting.

Harder-to-Chew Foods

Strangely, eating foods you must chew vigorously increases brain cell formation.

This makes a crunchy salad better for brain cell growth than juicing or making a smoothie with those same vegetables.

And while healthy fats are essential for brain health, a diet containing excessive amounts of saturated fat can slow down neurogenesis.

The Formation Of New Brain Cells

How To Regenerate Brain Cells

So what are some things that you can do to promote the formation of new brain cells? One of the best and most highly recommended ways is to exercise: more specifically, adding more aerobic exercises into your regimen. Aerobic exercises have been found not only to lead to an increase in cell production in the hippocampus but also to increase the amount of genetic information that is being encoded in the brain. As a result, the brain has seen improved functionality and the individual cells have been able to store information for learning and memory much better than before. Some types of aerobic exercises include jogging, power walking, and swimming.

Surprisingly, sex has also been found to enhance the number of newly generated neurons. However, it is not so much due to the physical act itself, but rather the fact that it is an incredible stress reliever. Chronic stress blocks the process of neurogenesis, so an activity that is both rewarding and lowers stress can have positive effects on the brain.

Another way to promote the production of new brain cells is, of course, by exercising your brain. Xen by Neuvana was designed to stimulate the vagus nerve, promoting wellness and relaxation throughout the body. The more glimpses of relaxation your brain gets, the more time youll be able to spend in that state. And the easier itll be to get there, thats thanks to neuroplasticity – your brains ability to create and strengthen pathways between neurons.

Impact Of Exercise On Neurogenesis

In a study from 2011, researchers compared a group of mice that were allowed to exercise by having a running wheel in their housing, with another group that didnt have access to a running wheel.When Neurogenesis Encounters Aging and Disease, Trends Neurosci. 2010 December ; 33: 569579. doi:10.1016/j.tins.2010.09.003,Orly Lazarov, Mark P. Mattson, Daniel A. Peterson, Sanjay W. Pimplikar, and Henriette van Praag

They found that aerobic exercise training increased the size of the hippocampus by 2% within just one year.

This reversed the age-related loss in volume by 1 to 2 years and led to improvements in memory.

Usually, the exact opposite happens when we age, where the hippocampus shrinks in late adulthood, which leads to impaired memory and increased risk for dementia.

After the study duration of one year, the aerobic exercise group demonstrated an increase in the volume of the hippocampus by 2%, while the control group displayed a 1.40% decline.

So, the difference in hippocampal volume between the people that exercised and the ones that didnt exercise amounted to 3.4% within just one year, which I think is astounding!

What kind of influence might this have on the chances of keeping our brain healthy if, as adults, we dont just exercise for one year, but for a decade or two decades or ideally our entire lives?I think theres going to be a pretty significant impact.

Also interesting to note is that the control group was not completely inactive.

Chronic Stress And Poor Sleep Habits

When you are experiencing stress, the amygdala, the area in your brain that partakes in emotional processing, signals your hypothalamus. As a response, your hypothalamus increases your heart rate encourages deeper intake of oxygen and heavier breathing, heightens your senses, rushes adrenaline in your body, and increases your cortisol levels. When the stress is over, everything should return to normal. However, when you are under stress, this stress response is never over.

Chronic stress leads to a build-up of cortisol in the body. Among many other functions, cortisol helps your hippocampus, where your memories are stored and processed. When you are under chronic stress and there is too much cortisol, it wears your brain down, impairs brain and memory function, disrupts synapse regulation, and kills brain cells. Chronic stress has a seriously negative effect on your memory and learning .

Regular poor sleep can also have a serious impact on your brain health. It may increase chronic stress, fatigue, and chronic inflammation, which may lead to brain fog, memory troubles, mood swings, low mood, and learning difficulties. According to research, sleep deprivation may even increase the risk of dementia and Alzheimers disease .;

Neurogenesis: How To Grow New Brain Cells

Adults can still grow new brain cells neurogenesis but what are they for?

For a long time scientists believed that neurogenesis was impossible: adults had all the brain cells they were ever going to have.

Now we know thats not true.

In fact, we continue to grow new brain cells into adulthood.

The race is on to find out what these brain cells are for and how we can grow more of them.

A new review of the scientific literature, published in the journal Trends in Cognitive Sciences,;argues that the growth of new cells aids adaptation to the environment .

The authors focus on new cells growing in the hippocampus, an area of the brain linked to memory and learning.

Maya Opendak, who co-authored the study, said:

New neurons may serve as a means to fine-tune the hippocampus to the predicted environment.

In particular, seeking out rewarding experiences or avoiding stressful experiences may help each individual optimize his or her own brain.

But neuroscientists led by QBI’s founding director, Professor Perry Bartlett, discovered stem cells in the hippocampus of the adult brain in the 1990s.;Because stem cells can divide, and differentiate into many types of cells, the game-changing discovery suggested that neurogenesis could hold the key to treating;conditions such as Alzheimers disease.;;

Neurogenesis is now accepted to be a process that occurs normally in the healthy adult brain, particularly in;the hippocampus, which is;important for;a learning and spatial memory. Damage to the hippocampus can lead to difficulties with navigation, as Dr Lavinia Codd found when, at age 31, she had a stroke that;damaged her right hippocampus.;;

Earlier this year, QBI researchers made the world-first discovery that;new adult brain cells are also produced in the amygdala, a region of the brain important for processing fear and emotional memories.

The amygdala, an ancient part of the brain, is important for attaching emotional significance to memories, and also plays;a key role in fear learning, which causes us to learn that an experience or;an object is frightening.

Fear learning leads to the classic flight-or-fight response increased heart rate, dry mouth, sweaty palms but the amygdala also plays a role in producing feelings of dread and despair, in the case of phobias or PTSD, for example, says lead researcher;Dr Dhanisha Jhaveri.

You Can Grow New Brain Cells Here’s How

Can adults grow new neurons? Until relatively recently, experts believed the answer was no.

But as neuroscientist Sandrine Thuret explains in a new TED Talk, humans can indeed generate new brain cells, a process called neurogenesis. More importantly, doing so has a range of important benefits, including improving mood, increasing memory formation and preventing the decline associated with aging.

Watch Thuret’s talk for all of the details, but a few key takeaways are below.

Stress, lack of sleep, and aging all reduce the natural rate of neurogenesis. Certain medications also restrict new neuron growth. Thuret notes that some cancer patients unexpectedly develop symptoms of depression even after being told they are cured of their cancer. Unfortunately, the drugs they’ve received not only stop cancer cells from multiplying, but alsostop “new neurons from being generated in their brain,” she says, which has a negative impact on their mood.

Conversely, learning, sex, and aerobic activity all increase neurogenesis.

In one of the first studies to highlight the links between aerobics and neurogenesis, Rusty Gage of the Salk Institute examined new brain cell growth in mice. The ‘control’ mice had no running wheel in their cages, while the ‘runners’ were able to run in their cages regularly. In the snapshots below, from Gage’s experiment, the black dots are new neurons-to-be.

Thuret also explains how dietary habits are crucial to new neuron growth.
