How brain waves shape our experience of mindfulness – Part 2

Welcome back to the second part of our exploration into the fascinating world of brain waves and mindfulness. In this continuation of our series, we delve deeper into the intricate relationship between brain waves and the practice of mindfulness. Understanding how our brain waves shape our experience of mindfulness can offer profound insights into our mental and emotional well-being.

Join us as we uncover the secrets behind harnessing harmony through the power of brain waves in this enlightening blog post.

Brain wave frequencies

THETA(3.5-7.5 Hz)

The subsequent frequency of brainwaves is theta, with a range of 3.5 to 7.5 Hz, characterized as “slow” activity.

This type of activity is often associated with creativity, intuition, daydreaming, and fantasizing, and serves as a storage space for memories, emotions, and sensations. During internal focus, meditation, prayer, and spiritual awareness, theta waves exhibit a prominent presence. It represents the bridge between wakefulness and sleep, and is closely linked to the subconscious mind. 

While it is abnormal in awake adults, it is considered a natural state in children under the age of 13 and during sleep.

Scientists believe that theta reflects activity from the limbic system and hippocampal regions. In instances of anxiety, behavioral activation, and behavioral inhibition, theta rhythm can be observed. 

When functioning properly, theta waves play a vital role in mediating and promoting adaptive and complex behaviors, such as learning and memory. However, during times of extreme emotional distress, like stress or disease, an imbalance in three major transmitter systems may result in abnormal behavior. 

Using our car analogy, theta can be compared to 2nd gear – not as slow as 1st gear (delta), but still not very fast.

In terms of distribution, theta activity is usually regional and can involve multiple lobes, with the potential to be lateralized or diffuse. It can induce a variety of subjective feelings, such as intuition, creativity, recall, fantasy, imagery, and a dreamy state. 

It is also linked to the ability to switch thoughts and drowsiness, and can trigger a sense of “oneness” and “knowing.” Some associated tasks and behaviors include creativity and intuition, but it can also lead to distraction and a lack of focus. 

On the physiological level, theta waves have been linked to healing and the integration of mind and body. Through training, theta waves can be enhanced, inducing a drifting, trance-like state, or suppressed, improving concentration and the ability to focus attention.

ALPHA (8-12 Hz)

The frequency of alpha waves falls between 8 Hz to 12 Hz and reaches its peak around 10 Hz. The production of alpha waves promotes mental resourcefulness, enhances the ability to coordinate mentally, and induces a sense of overall relaxation and reduced fatigue. 

This state enables one to move quickly and efficiently to complete any given task. Most people experience a feeling of ease and calmness when alpha waves predominate. It is believed that alpha waves bridge the conscious and subconscious mind together. They are commonly seen in relaxed adults and continue to stay present throughout life after the age of thirteen, where they dominate the resting tracing. 

Alpha rhythms originate from the white matter of the brain, which acts as a connector between different parts of the brain. Alpha waves are strong over the occipital cortex (back of the head) and the frontal cortex. Introverts tend to show lower levels of alpha, whereas extroverts exhibit higher levels. 

Alpha has also been linked to creativity, as creative individuals show increased alpha activity when solving creative problems. 

It is also associated with mental work and can be considered as a marker for alertness and sleep. When alpha waves are within normal ranges, individuals tend to experience positive moods, perceive the world accurately, and feel a sense of calmness. 

It is one of the most important frequencies for the brain to learn and process information, both in the classroom and on the job. 

Alpha can be strengthened through activities such as closing one’s eyes or practicing deep breathing, while thinking or calculating can reduce it. Training in alpha-theta can lead to improved sensation, abstract thinking, and self-control. Relating this to our car scenario, alpha can be considered as the neutral or idle state that enables smooth transitions between different tasks.

BETA (13-35 Hz)

Beta brain waves is considered “fast” activity and reflects a desynchronized, active brain. It is typically seen evenly on both sides and most prominently in the frontal lobe. In areas of cortical damage, beta may be absent or reduced.

This rhythm is widely accepted as normal and is the dominant rhythm in individuals who are alert, anxious, or have their eyes open. When we are actively engaged in analytical problem solving, judgment, decision making, or processing information about the world around us, our brain is predominantly in a beta state. Comparatively, beta can be likened to overdrive or hyperdrive in terms of a car’s capabilities.

The beta band encompasses a wide range and can be divided into low, midrange, and high subcategories.

Low beta (12-15Hz)

Low beta, with a frequency of 12-15Hz, is localized by side and lobe (frontal, occipital, etc.). This state is associated with a relaxed yet focused feeling and integrated thinking. Lack of focused attention or “ADD” can be reflected by low SMR. Inhibiting movement can decrease SMR, while actively restraining the body may increase it. Through training, increasing SMR can lead to relaxed focus and improved attentive abilities.

Mid beta (15-18 Hz)

• Allocation: concentrated, spanning multiple regions. Potentially centralized around one specific electrode.
• Emotional states: contemplation, cognizant of self and surroundings.
• Related duties and actions: cerebral pursuits.
• Physiological indicators: awake, energetic, not restless.
• Consequences of Practice: potential increase in cognitive prowess, concentration, vigilance.

High beta (above 18 Hz)

• Distribution: concentrated, potentially with great intensity.
• Emotional states: heightened attentiveness, restlessness.
• Related duties and actions: mental exertion, such as problem-solving and strategizing.
• Physiological indicators: overall stimulation of mental and physical functions.
• Consequences of Practice: may induce heightened vigilance, but could also bring about restlessness.

GAMMA (above 30 Hz)

Originating from the frequency range above 30 Hz, Gamma brain waves display a highly localized distribution.

• Subjective feelings: Thought-intensive; streamlined thoughts with enhanced coherence.
• Related tasks and behaviors: Facilitates high-level processing of complex information; aids in the act of “binding” together various cognitive processes.
• Physical manifestations: Linked to the processing of information-dense tasks.
• Training effects: Yet to be determined.

Gamma waves, ranging between 30 to 44 Hz, are present across all regions of the brain. It is proposed that the 40Hz frequency aids in the simultaneous processing of information from multiple areas of the brain.

Well-regulated and effective 40Hz activity is associated with superior memory, while a deficiency in 40Hz can lead to difficulties in learning.

Exploring the mysterious phenomenon of gamma brain waves

Intricately interconnecting the different regions of the brain, scientists postulate that gamma waves possess the unique capability of integrating information.

Originating from the thalamus, these waves sweep across the brain at a frequency of 40 times per second, stimulating peak performance at both a cerebral and physical level. As a result, the state of gamma is often referred to as being “in the zone”.

Seasoned meditators, such as monks and nuns, report experiencing a “feeling of blessings” during this state – providing further evidence of its association with heightened concentration and optimal cognitive functioning.

While all individuals have some degree of gamma wave activity in their brain, the quantity produced varies. Research has linked lower levels of gamma brainwaves to difficulties in learning, poor memory retention, and impaired mental processing.

Despite its universal presence, tapping into altered states of consciousness and utilizing gamma waves to make a profound impact in the world is not a skill typically taught in human education.

The scientific examination of gamma brain waves has revealed intriguing insights. One highly acclaimed study involved Tibetan Buddhist monks and Celestine nuns, both of whom exhibited the ability to generate gamma waves during meditation.

Notably, the studies displayed a dramatic escalation in neural activity in the left prefrontal cortex, the brain region linked to self-discipline, joy, and empathy.

Additionally, reduced activity in the amygdala, the brain’s “fight or flight” center, was observed. This strongly suggests that meditation has the potential to increase happiness and compassion.

Gamma brain waves, compassion and mindfulness

However, a fascinating occurrence unfolded when the monks were instructed to focus on feelings of compassion. Their brains swiftly transitioned into the gamma frequency, displaying a rhythmic and coherent pattern.

When practicing meditation with the accompaniment of meditation music, one may begin to feel the all-encompassing warmth of unity, where the concept of self dissolves and merges with universal consciousness.

Hold on to this sensation, center your focus on it, and allow it to flourish. Embrace it. Let it become a part of you.

Channel love from within and let it radiate outwards, permeating every fiber of your being. By concentrating on love, one can experience the euphoria and contentment that comes with being in the gamma state.

But how does one access and amplify gamma brain waves? According to experts in neuroscience, it is possible to train your brain to increase its gamma frequency. In fact, by honing in on compassion and love, one can elevate their gamma output.

Elite athletes offer a prime example of how love engenders the gamma state – they love what they do and are engrossed in their passion, thereby naturally stimulating their brain’s gamma activity.

How to unlock enhanced cognitive functioning

So how can you unlock enhanced cognitive functioning, happiness, heightened perception, laser-sharp focus, robust self-discipline, and indulgent sensory experiences all tied to the gamma state? The answer is simple: meditate.

Meditation not only sharpens one’s mental acuity, but by mastering the ability to induce greater gamma brain wave activity, you can unlock your mind’s full potential.

A fourteenth century Tibetan text describes it:

(…) a state of bare, transparent awareness;
Effortless and brilliantly vivid, a state of relaxed, rootless wisdom;
Fixation free and crystal clear, a state without the slightest reference point;
Spacious empty clarity, a state wide open and unconfined;
The senses unfettered…
