Yes. Many methods have been proposed.

The question asks whether anyone has suggested such methods, and plainly many have, from self-help authors and educators to supplement makers and neurotechnology firms. The framing 'alleged brain potential' fits the evidence: the idea that most of the brain sits unused is not supported by neuroscience. Still, people can improve particular skills through practice and healthy habits, and some approaches such as exercise, sleep, and learning have reasonable support for maintaining or modestly improving cognition, while claims of dramatic unlocking are mostly unsupported.

• The '10% of the brain' idea is a long-standing misconception; imaging shows virtually all brain regions are active over a day.
• Commercial brain-training games mostly improve the practised task, with little evidence of broad transfer to general intelligence.
• Aerobic exercise, good sleep and learning new skills have modest evidence for supporting cognitive health.
• Nootropics, 'smart drugs' and transcranial stimulation have mixed or limited evidence for healthy people, and carry side-effect risks.
• Self-help and educational proposals (speed-reading, mnemonics, mind-mapping, subliminal tapes) are widely marketed but of varied or little proven benefit.

The question asks whether anyone has suggested methods, not whether every proposed method works, so the answer is clearly yes. There is evidence that training can improve particular cognitive skills, but broader claims about unlocking hidden brain capacity are a different proposition and are not established by those improvements.

• Cognitive-training programs target memory, reasoning, and processing speed.
• The ACTIVE trial found improvements in the abilities specifically trained among older adults.
• Meditation and mindfulness have been studied for possible effects on brain functioning and structure.
• The claim that people normally use only 10 percent of their brains is false.

Throughout the 20th and 21st centuries, numerous individuals and organizations have marketed techniques purporting to unlock untapped mental reserves. These have ranged from meditation and visualization systems (like José Silva's Silva Method) to mnemonic systems, speed-learning protocols, and digital brain-training software. Most such programs historically drew on the popular misconception that humans utilize only a small fraction of their brain. While legitimate cognitive training, healthy habits, and education can strengthen neural connections via neuroplasticity, neuroscience has thoroughly debunked the idea that large portions of the brain sit unused waiting to be unlocked.

• Widely promoted systems, such as the Silva Method, Dianetics, and various 'brain-training' courses, have claimed to unlock latent cerebral potential.
• These claims often rely on the persistent myth that humans only use 10% of their brain capacity.
• Modern neuroimaging technologies (such as fMRI and PET) prove that virtually all areas of the brain are functionally active throughout everyday life.
• Evidence-based practices like physical exercise, formal education, adequate sleep, and targeted practice improve cognitive performance through neuroplasticity, not by activating dormant brain areas.

The question asks whether methods have been suggested, not whether they work, and the answer to that is plainly yes: popular science, self-help, and academic literature are full of them. The phrase "alleged brain potential" points at the common myth of a large unused reserve, which neuroscience does not support, but that affects whether the methods are needed, not whether they have been proposed.

• The popular claim that humans use only about 10% of their brains is false; imaging shows activity throughout the brain over the course of a day, though not all regions are active at once.
• Cognitive-training programmes such as dual n-back have been studied extensively; reviews find that people get better at the trained task but transfer to general intelligence is small or absent.
• Physical exercise, adequate sleep, and treatment of hearing or vision loss are among the better-evidenced ways to support cognitive function, especially with age.
• Meditation and mindfulness have shown modest effects on attention and stress measures in randomised trials, with effect sizes generally small.
• Nootropic drugs and supplements are widely marketed for enhanced cognition, but evidence for reliable benefit in healthy people is limited, and some carry side effects.

The claim that humans only use a small fraction of their brain (e.g., 10%) is a well-debunked myth. Neuroscientific evidence, including functional MRI and PET scans, shows that humans use virtually all of their brain, even during simple tasks. However, many methods have been suggested to enhance cognitive function and optimize brain performance. These include cognitive training (e.g., puzzles, learning new skills), physical exercise, a balanced diet rich in omega-3 fatty acids, neurofeedback, and brain stimulation techniques such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS). While these methods are supported by varying levels of evidence, they focus on improving existing brain function—such as memory, attention, and mental clarity—rather than unlocking dormant or hidden potential. The concept of neuroplasticity, the brain's ability to reorganize itself by forming new neural connections, underpins many of these approaches. However, there is no scientific basis for the idea that large areas of the brain remain unused and can be "activated" to achieve extraordinary abilities.

• The 10% brain utilization myth is scientifically debunked; humans use virtually all of their brain.
• Neuroscience supports methods like cognitive training, physical exercise, diet, and neurofeedback to enhance cognitive function.
• Brain stimulation techniques (e.g., TMS, tDCS) are being researched for cognitive enhancement but carry risks and are not widely adopted by neuroscientists for self-use.
• Neuroplasticity allows the brain to adapt and improve through learning, environmental enrichment, and healthy habits.
• No evidence supports the idea of unlocking hidden or unused brain potential, but evidence does support improving communication between brain regions and refining neural pathways.
