by Advancements in technology have led to the emergence of numerous apps and devices claiming to manipulate brain states and brain waves. The concept of changing one’s mental state might seem intriguing, but it raises questions about the plausibility and efficacy of such interventions. While the evidence surrounding this topic is still inconclusive, our understanding of the brain is expanding rapidly, thanks to the continuous improvement of investigative methods.
In the 1980s, magnetic resonance imaging (MRI) revolutionized our knowledge of brain activity. The development of functional MRI further allowed us to link brain function and behavior by measuring the brain’s use of oxygenated blood in real-time during specific tasks. Additionally, electroencephalography (EEG) enables the measurement of electrical activity, providing accurate timing information on brain waves. However, it lacks precision in identifying the specific brain regions involved in this activity. On the other hand, measuring the brain’s response to magnetic stimulation offers precise information regarding both timing and location, but only for superficial regions. These various methods of measurement each have their trade-offs and limitations.
Brain activity, or neural activity, serves as the foundation for all our thoughts and behaviors. Neurons, the nerve cells of the brain, communicate through a series of electrical impulses and chemical signals called neurotransmitters. To measure brain activity accurately, it is necessary to monitor electrical activity, neurotransmitter levels, or blood flow. Measurement can be performed at different levels, including single-cell, network, or whole-brain activity.
At the single-cell level, measuring individual neuron communication is challenging and provides a limited perspective. Network-level measurements capture the activity of multiple neurons or networks, while whole-brain activity patterns encompass various brain states. A brain state refers to recurring activity patterns distributed across the brain, emerging from physiological or cognitive processes and related to behavior. These states involve the synchronization of different brain regions, primarily observed in animal models.
The most extensively studied brain states in both animals and humans are arousal and resting states, representing different levels of alertness. Environmental factors and activities influence these states. Tasks demanding high cognitive engagement induce attentional brain states with increased connectivity. On the other hand, mind-wandering is a state dissociated from the external world and tasks, characterized by a lack of connection to reality.
Can we deliberately and intentionally influence our brain states? The current understanding suggests that it might be too simplistic to assume that we can control brain states effectively, given the complexity of the mechanisms involved. However, researchers are exploring various approaches, including the use of drugs, environmental cues, mindfulness practices, meditation, and sensory manipulation.
One controversial technique is neurofeedback therapy, which utilizes brain wave patterns. In this therapy, individuals receive feedback based on their brain wave activity and are encouraged to maintain or alter it by controlling their thoughts, relaxing, or adopting specific breathing techniques. This approach has been predominantly applied in mental health settings, particularly for individuals who have experienced trauma or struggle with self-regulation.
Despite the intuitive appeal of neurofeedback therapy, the issue of multiple brain states coexisting simultaneously remains unaddressed. Clinical studies on its effectiveness have yielded inconclusive results, and proponents of this therapy are frustrated by the lack of mainstream support. Other neurofeedback methods involve using MRI-generated data to provide signals to participants during mental tasks, aiming to activate brain regions associated with positive emotions. However, the evidence supporting these techniques remains mixed.
It is important to note that treatments like neurofeedback therapy can be costly, and their success may depend not only on the therapy itself but also on the therapeutic relationship between the practitioner and the individual. While there is no evidence to suggest that these treatments pose any harm, they may potentially delay the implementation of proven beneficial interventions.
In conclusion, the field of brain states and brain waves continues to be a topic of exploration and debate. While there is still much to learn and understand, advancements in technology and research methodologies provide hope for deciphering the complex mechanisms underlying brain activity and potentially harnessing its power for therapeutic purposes.
