The human brain is a complex network of billions of neurons and non-neuronal cells. These cells communicate with each other through electrical impulses and chemical signals, which are carried by ions. This process of electrochemical signalling is what gives rise to our thoughts, feelings, and actions. While it is not possible to control a person's mind with electrical impulses, it is possible to influence brain function and behaviour using electromagnetic waves and electrical stimulation. For example, studies have shown that electromagnetic radiation from cell phones can affect brainwave activity and behaviour. Additionally, techniques such as transcranial direct current stimulation (tDCS) can be used to stimulate specific regions of the brain, leading to enhanced cognitive functions and improved mood regulation. However, the idea of directly controlling someone's actions or thoughts through electrical impulses alone is purely speculative and not supported by scientific evidence.

The human brain's electrical impulses
The human brain is a complex network of billions of neurons and non-neuronal cells that communicate with each other through electrical impulses. These electrical impulses are the foundation of our thoughts, feelings, perceptions, and understanding of the world. As you read this, billions of electrical impulses are firing across your brain, encoding information and facilitating your comprehension.
Each neuron has a unique structure, with dendrites at the front and a cell body at the centre. The cell body performs vital functions to keep the neuron alive and carries out various cellular and genetic processes. Attached to the cell body is the axon, through which electrical impulses travel until they reach the synaptic terminals. At the synapses, the electrical signal is converted into a chemical message, triggering new electrical impulses in the downstream neurons. This intricate process allows for the simultaneous propagation of billions of signals across the brain.
The complexity of the human brain and its electrical impulses is astonishing. There are about 85 billion neurons in an adult human brain, each capable of forming connections with thousands of other neurons. This creates an incredibly dense network of information processing and transmission. To put it into perspective, the number of connections between neurons is a staggering 10 quadrillion, or a '1' followed by 16 zeros!
While the brain's electrical impulses are not fully understood, researchers have made significant progress in visualizing and studying them. For example, scientists from Boston University and the Massachusetts Institute of Technology developed a voltage-sensing molecule that fluoresces when brain cells are electrically active. This technique provides a clearer picture of brain cell activity and allows for the observation of individual neurons firing within the brains of mice. Additionally, optogenetics, a technique pioneered by Han and Boyden, enables researchers to turn brain cells on and off with laser light, offering further insights into the brain's electrical activity.
The brain's electrical impulses also play a crucial role in insulating brain cells and speeding up communication between them. Neurons coated with an insulating material called myelin conduct electrical impulses more efficiently. Mental activity appears to influence myelination, as stimulating environments and learning activities promote the production of myelin. On the other hand, certain mental disorders, such as schizophrenia and bipolar disorder, are associated with decreased myelin levels.
While the idea of mind control through electrical impulses has captured the imagination of many, it is important to recognize the complexities involved. Some sources suggest that a deep understanding of the brain's intricate workings and the ability to precisely manipulate specific impulses may lead to some form of influence over another person's actions or thoughts. However, the human brain is highly complex and unique to each individual, making accurate and safe manipulation incredibly challenging. Furthermore, disrupting the electrical functioning of the brain, as seen in the case of electric shocks, can lead to uncontrolled seizures and a loss of consciousness rather than controlled mind influence.

Mind control through magic
Mind control is a power that is often associated with magic and the supernatural. In popular culture, mind control or mental manipulation is depicted as the ability to control the minds of others, influencing their thoughts and actions, and even taking away their free will.
While the idea of mind control through magic may seem far-fetched, it is a concept that has been explored in various forms of media, including books, TV shows, and games. For example, in the "Witches of East End" universe, characters like Frederick use mind-related spells and incantations to control the actions of others. Similarly, in "Fairy Tail," Zash Caine uses his mind control magic to control a target's mind via eye contact.
The concept of magical mind control is also present in card and video games, where players can use "mind control" cards or spells to take control of their opponent's creatures or characters. These games often involve strategic manipulation and the ability to bend the minds of opponents to one's will.
In reality, the idea of controlling someone's mind by manipulating their electrical impulses is a topic of scientific discussion and speculation. Some people believe that a magic user, with an intimate understanding of the human brain, could theoretically manipulate another person's actions by controlling the electricity within their brain. However, this raises ethical concerns and is considered a morally dubious form of magic due to its potential to dispossess individuals of their free will.
While it may be theoretically possible, the human brain is incredibly complex, and the process would require a deep understanding of the intricate workings of synapses and electrical impulses. Any errors in attempting such a feat could potentially be harmful, and the energy required for this process may not be feasible.
In conclusion, while mind control through magic and electrical impulse manipulation may capture our imaginations, it is important to approach these concepts with caution and a critical eye, weighing the ethical implications and the potential risks involved.

Cell phones and electromagnetic radiation
While it may be theoretically possible to control a person's actions by manipulating the electrical impulses in their brain, it is not feasible in practice. This is because an extremely intimate understanding of the intricate workings of the brain, down to the synapse level, would be required to execute such a task.
Cell phones, like FM radio waves, microwaves, visible light, and heat, emit non-ionizing radiation in the form of RF waves. This is a type of electromagnetic radiation that does not have enough energy to cause cancer by directly damaging DNA or genes inside cells.
However, studies have shown that cell phone signals can alter a person's behavior during a call, and the effects of the disrupted brain-wave patterns can continue even after the phone has been switched off. This is because cell phones in talk mode are particularly well-tuned to frequencies that affect brainwave activity. These findings have sparked interest in further research to determine whether different doses, durations, or devices could have greater effects.
It is important to note that there are currently no consistent findings that indicate an increased risk of cancer or other health issues due to exposure to non-ionizing radiation from cell phones. The European Commission Scientific Committee on Emerging and Newly Identified Health Risks concluded in 2015 that epidemiologic studies on cell phone radiation exposure do not show an increased risk of brain tumors or other cancers of the head and neck region.

Deep brain stimulation
The procedure typically involves implanting small wires, known as leads or electrodes, into the brain during surgery. These leads are connected to a neurostimulator, a small electrical generator implanted under the collarbone, similar to a heart pacemaker. The neurostimulator delivers continuous electrical impulses through the leads to the targeted areas of the brain.
Proper patient selection, precise placement of the electrodes, and careful adjustment of the neurostimulator are critical for the success of DBS. The programming of the neurostimulator is a complex and individualized process that may require multiple appointments to ensure optimal symptom control while minimizing side effects.
DBS has been studied and used to treat a range of conditions beyond movement disorders, including obsessive-compulsive disorder (OCD), treatment-resistant epilepsy, and neuropsychiatric conditions. While DBS can significantly improve quality of life and reduce symptoms, it is not a cure. Long-term mortality rates with DBS are up to 17%, and there are various neurological and psychological side effects that can occur, including cognitive impairment, memory deficits, speech difficulties, and emotional disturbances.
While DBS does not involve the direct "mind control" that is often depicted in fiction, it demonstrates the potential for electrical impulses to modulate brain function and influence behaviour. The use of DBS in treating various conditions highlights the complex interplay between electrical impulses and brain function, providing valuable insights into the internal workings of the mind.

Transcranial direct current brain stimulation
Transcranial Direct Current Stimulation (tDCS) is a non-invasive brain stimulation technique that delivers a low electric current to the scalp. It is a popular method used to modulate cortical excitability, producing facilitatory or inhibitory effects on a variety of behaviours. The technique has gained prominence over the past decade, with 1,500 articles published on the topic between 2011 and 2015.
The tDCS device has two electrodes, which are placed over specific areas of a patient's head or neck, depending on individual needs. These electrodes deliver a very low-level electric current that influences the activity in the brain or spinal cord. The position of the anode and cathode electrodes on the head determines the flow of the current to specific brain regions. The current delivered by the tDCS is not strong enough to trigger an action potential in a neuron. Instead, it brings about "sub-threshold" changes in the pattern of neuronal activity.
The tDCS technique is used to enhance the benefits of physical, occupational, or speech therapy and hasten the return of lost skills, from language to movement, balance, and everyday functioning. It can be used to stimulate specific parts of the brain involved in certain activities, such as walking or speaking. tDCS can also be used to increase cortical excitability, with research showing that daily tDCS leads to greater increases in cortical excitability than second-daily tDCS.
While tDCS is generally well-tolerated, some patients may experience mild side effects such as itching, tingling, pins and needles, or a burning sensation under the electrode pads. These sensations usually dissipate within a few minutes. Other possible side effects include mild headaches, dizziness, or minor fatigue following treatment. It is important to note that tDCS should not be used for individuals with metal objects in their head, eye, or neck regions, or those with implanted electrical devices such as pumps, stimulators, or pacemakers.

Frequently asked questions
Mind control with electrical impulses is theoretically possible, but it is not feasible because one needs to know the workings of the brain intimately to execute this.
To control a person's mind, one would have to know which impulses sent where would do what. As the internal structure of the brain varies from person to person, the controller would need to understand the other person in depth.
Electrical impulses are the fundamental units of the brain's complexity and information processing. They are carried by ions, which are electrically charged chemical species.
Electrical impulses are triggered by chemical messages that cross over at the synapse to other neurons. These impulses then travel down the axon and end at the synaptic terminals, where a biochemical process passes the signal along to other neurons.
