Hyper memory, synaesthesia, savants Luria and Borges revisited

Area of Science:

• Neuroscience
• Psychology
• Cognitive Science

Background:

• Individuals with hyper memory often exhibit synaesthesia and autistic spectrum disorder (ASD) traits.
• Clinical and fictional cases, like Solomon Shereshevsky and Borges' Funes the Memorious, present unique memory capabilities.
• Understanding the interplay of these conditions is crucial for cognitive research.

Purpose of the Study:

• To investigate the relationship between hyper memory, synaesthesia, and autistic spectrum disorder (ASD).
• To explore how synaesthesia and ASD characteristics contribute to superior memory.
• To examine the impact of cognitive deficits in abstraction and categorization on hyper memory.

Main Methods:

• Clinical case study analysis of Solomon Shereshevsky.
• Literary analysis of J. L. Borges' fictional character Funes the Memorious.
• Review of existing literature on memory, synaesthesia, ASD, and neural connectivity.

Main Results:

• Hyper memory in synaesthetes may be linked to ASD-savant syndrome characteristics.
• Severe deficits in categorization, abstraction, and metaphorical functions significantly impair hyper memory.
• Altered neural connectivity in the medial temporal lobe and prefrontal regions is implicated.

Conclusions:

• ASD-savant syndrome may underlie hyper memory, but cognitive limitations pose challenges.
• Neural connectivity alterations are a potential factor in the observed memory and cognitive profiles.
• Further research is needed to fully elucidate the complex mechanisms of hyper memory.
