Your brain needs 7 senses, not 5, to learn better, say scientists

Memory, proposes a recent study, works best in a seven-dimensional space. According to research, humans and AI might benefit from having seven senses rather than five. This new mathematical model could transform how you understand memory, perception, and learning in both biological and artificial systems.

It’s long been drummed into us that humans have five senses – sight, smell, taste, touch, and hearing. But what if we’re missing two? Scientists at Skoltech in Russia believe the brain might actually work more efficiently with seven. Their new memory model suggests that learning and recall hit peak performance when concepts are processed through seven sensory-like dimensions. It’s a revelation that could shake up neuroscience and AI development.

The Math behind Memory's Superpower:

Published in Scientific Reports, the research introduces a model where memory is shaped by "engrams" — neural fingerprints of concepts. These engrams live in a multi-dimensional mental space, each one defined by sensory input.

Currently, we think of this space as five-dimensional, aligned with our five senses. But Skoltech researchers say memory performs best when this mental map is built using seven features or “senses.” In this seven-dimensional space, the brain can store and recall more distinct concepts than with five or even eight.

Not just humans, AI could use a seventh sense too:

Though the idea of adding two more senses might sound like science fiction, the researchers are quick to clarify this isn't about humans growing antennae or X-ray vision. Rather, it’s about how our brains – and potentially artificial ones – could use broader or additional channels of information.

For AI, this means designing smarter systems that “sense” beyond our current human capabilities. Think of machines that learn and recall with richer, more complex understanding than ever before.

How this mind model actually works

Memory engrams: Represent specific concepts stored in the brain; they evolve over time.

Conceptual space: Like a brain map where each concept sits in a space defined by sensory features.

Seven dimensions equals maximum memory: The model finds that seven features allow the highest memory capacity.

Learning and forgetting: Concepts strengthen or fade depending on repeated exposure, much like real life.

AI and robotics use: This model might inspire new ways of building artificial minds with more adaptive memory.

Professor Brilliantov, co-author of the study, reveals this is speculative for humans – saying "we’re not about to grow a magnetism sense overnight. But evolution and tech could bring surprising changes. It’s more likely, in the near future, that AI systems could simulate this seventh sense first, helping us build more humanlike, or even superhuman, intelligence."

FAQs on How To Boost Memory

1. What are the best techniques to improve memory?

Engage in regular mental exercises, maintain a healthy diet, get sufficient sleep, and practice mindfulness to enhance memory.

2. Does physical exercise help with memory improvement?

Yes, regular physical exercise increases blood flow to the brain, improving cognitive functions and memory.

3. Can memory be enhanced by using all senses?

Yes, incorporating multiple senses when learning new information can strengthen memory retention.

4. How does adequate sleep contribute to better memory?

During sleep, the brain consolidates memories, making proper sleep essential for effective memory retention.

5. Are there specific foods that boost memory?

Foods rich in antioxidants, omega-3 fatty acids, and vitamins, such as berries, fish, and nuts, can support brain health and memory function.
