Scientists Find Seven Senses Maximize Memory

Scientists Find Seven Senses Maximize Memory

A new Skoltech study suggests memory works best with seven sensory dimensions, not five, boosting potential for AI and neuroscience.

New Model Challenges Five-Sense Norm

A team from Skoltech has produced evidence that the brain's memory capacity may be optimized with seven distinct sensory features—not five. Published in Scientific Reports, their mathematical model shows a sharp peak in possible memory storage when concepts are represented with seven sensory dimensions.

Engrams and Memory Encoding

  • Memory engrams, clusters of firing neurons, are central to the research.

  • Each memory—like a banana—gets encoded as a point in a sensory space. Traditionally, these are the classic five senses.

  • Skoltech's model finds memory storage soars with seven features. Less or more, and capacity drops.

This finding was confirmed through mathematical simulations and theoretical analysis (Skoltech news).

Broader Impact: Humans and AI

The model has implications beyond human biology. While it's speculative that humans could evolve new senses, the finding could shape the engineering of artificial intelligence and robotics, where input features can be custom-designed.

Implications for Technology

  • AI and robots could be built with seven distinct input streams for optimal memory and learning (ScienceDaily).

  • Extra senses in humans—such as magnetic or radiation detection—could, in theory, follow this architecture.

Memory Dynamics

The model simulates how memories sharpen or fade with use or neglect, mirroring biological learning and forgetting patterns. Over time, these representations reach a steady state, balancing reinforcement and decay (ScitechDaily).

Expert Views and Ongoing Questions

This research reframes the 'magic number seven' in memory theory, suggesting it's not just a short-term limit but rooted in sensory encoding dimensions. Skepticism remains on biological feasibility, but the model could quickly influence AI system design.

Key Sources and Debates

  • Read the Skoltech release for diagrams and author interviews.

  • Science forums and social media are debating practical uses and the possibility of new human senses.

How does the seven-dimensional conceptual space enhance memory capacity?

The model shows that encoding information across seven distinct sensory features maximizes the number of unique memories that can be stored, outpacing five or six dimensions.
