In the late 18th century, an Italian scientist named Luigi Galvani conducted fascinating experiments involving dead frog legs. He discovered that these legs would twitch when exposed to an electric spark, revealing the electrical nature of nerve impulses. Fast forward to today, and similar techniques using direct current are being explored to enhance brain function. Galvani’s contemporary, Alessandro Volta, engaged in a scientific debate with him, questioning whether direct current was the essence of life or simply a trigger for muscle movement in dead tissue. The scientific consensus leaned towards Volta’s view, suggesting that electricity merely caused movement in dead muscles rather than being a life source. This debate even found its way into literature, inspiring Mary Shelley’s “Frankenstein,” which delved into the concept of reanimating life.
Direct current stimulation has evolved and is now used for therapeutic purposes, such as addressing sleep disorders and mental health issues. A contemporary technique, Transcranial Direct Current Stimulation (tDCS), is employed to enhance cognitive functions like working memory and to alleviate depression. This method involves a steady, low electrical current—comparable to that of a 9-volt battery—passing through electrodes to stimulate neurons in targeted brain areas, thereby facilitating neuronal firing and boosting cognitive capabilities.
Research has demonstrated the potential benefits of tDCS. In one study, stroke patients with speech difficulties showed significant improvement in naming common nouns after receiving tDCS, with effects lasting even a week later. Another study revealed that applying tDCS to the motor cortex increased participants’ pain thresholds. PET scans showed that electrical stimulation led to increased opioid release in the brain, acting as natural painkillers.
We are on the brink of a new era in understanding the mind, reminiscent of the time when Mary Shelley wrote “Frankenstein” and we were just beginning to comprehend the interplay between electricity and the human body. The potential clinical benefits of tDCS are impressive, prompting some individuals to create DIY brain stimulation kits at home. While this practice does not equate to reanimating life, it involves using electrical currents to alter cognitive states. However, it is crucial to approach this with caution, as expertise is required to target the correct brain areas; stimulating certain regions can inadvertently inhibit others. The long-term risks of such practices remain uncertain.
In a recent study, participants were left alone in a room and asked to entertain themselves with their thoughts, with the option to administer an electric shock to themselves. Surprisingly, over two-thirds of the male participants chose to shock themselves rather than remain alone with their thoughts, offering intriguing insights into human behavior.

Back in the 1780s, Italian scientist Luigi Galvani conducted experiments with dead frog legs and observed that they twitched when struck by an electric spark. He demonstrated the electrical basis of nerve impulses. Now, hundreds of years later, similar direct current techniques are being used to enhance brain function. Galvani and another Italian scientist, Alessandro Volta, debated whether direct current was the spark of life or merely triggered the movement of dead muscles. The scientific community leaned towards Volta’s perspective, believing that electricity caused movement in dead muscles rather than being a source of life itself. This scientific discourse was reflected in fiction, notably in Mary Shelley’s “Frankenstein,” where the reanimation of a creature was explored.
Direct current stimulation has continued to be used for therapeutic purposes, such as treating sleep disorders and mental health issues. Recently, Transcranial Direct Current Stimulation (tDCS) has been employed to enhance working memory and alleviate depression. This technique involves a constant, low current—similar to a 9-volt battery—traveling through electrodes to stimulate neurons in specific brain regions. It facilitates neuronal firing and boosts cognitive abilities.
In one study, tDCS was applied to stroke patients with speech difficulties, resulting in significant improvements in their ability to name common nouns, even after a follow-up test a week later. Another study found that applying tDCS to the motor cortex increased participants’ pain thresholds. PET scans indicated that following electrical stimulation, there was an increase in opioid release in the brain, acting as natural painkillers.
We are on the verge of a new understanding of the mind, reminiscent of the era when Mary Shelley wrote “Frankenstein” and we were beginning to grasp the complexities of electricity and the human body. The potential clinical benefits of tDCS are remarkable, leading some individuals to create their own kits at home for brain stimulation. While this may not be akin to reanimating life, it does involve using electrical currents to alter one’s cognitive state. However, it is important to note that this practice is complex and requires expertise to target the correct brain areas, as stimulating certain regions can inhibit others. The long-term risks of such practices remain unknown.
In a recent study, participants were left alone in a room and asked to entertain themselves with their thoughts, with the option to administer an electric shock to themselves during this time. Over two-thirds of the male participants chose to give themselves electric shocks rather than remain alone with their thoughts, suggesting a deeper psychological insight into human behavior.
Speaking of Mary Shelley’s work, a modern adaptation titled “Frankenstein MD” offers an intriguing look at science through the experiments of Victoria Frankenstein, MD in training.
