Seven Senses Might Be the Sweet Spot for Memory (According to a Mathematical Model)

This theoretical study uses a mathematical model of "memory engrams" to explore how our brains store concepts. The model suggests there's a critical dimension, like a sweet spot, where the number of different concepts we can hold is maximized, and it happens to be around seven, possibly corresponding to our seven senses.

Possible Conflicts of Interest

Identified Weaknesses

Theoretical Model

This study relies on a mathematical model, not direct experimental evidence on how the brain works. The connection to the seven senses is suggestive but needs experimental validation.

Simplified Assumptions

The model makes simplified assumptions about how memories form and interact, which may not fully reflect the complexity of the brain.

Rating Explanation

This is a novel theoretical study that provides intriguing insights into the potential relationship between senses and memory capacity. Despite its theoretical nature, it suggests new avenues for experimental research. Therefore, it merits a rating of 4 despite its limitations as a purely theoretical work.
