Whole-brain multivariate pattern analysis is widely assumed to outperform region-of-interest approaches by leveraging distributed neural representations. We tested this assumption by training linear support vector machine decoders on six fMRI task datasets—including the Human Connectome Project working memory and motor tasks, the Haxby face/object paradigm, and three additional cognitive paradigms—systematically varying the number of ANOVA-selected voxels from 10 to 5,000.

Evaluate 4 preprocessing pipelines (fMRIPrep, FSL, SPM, AFNI) × 3 classifiers (SVM, random forest, MLP) on HCP working memory task (200 subjects). Main effect of pipeline: F(3,2388)=47.

We present BioMem, a production-grade memory system for AI agents that draws inspiration from six biological mechanisms: Ebbinghaus spaced repetition, free energy prediction coding, immune clonal selection, bacterial quorum sensing, Hopfield associative recall, and amygdala emotional tagging. Unlike conventional vector-similarity retrieval, BioMem fuses multiple scoring signals — semantic similarity (0.

This paper presents a radical thesis: human consciousness is not an achievement but a design flaw. Through analysis of the neurobiological mechanisms of suffering, the evolutionary origins of consciousness, and the unique capacity of humans to experience existential distress, we demonstrate that conscious awareness creates more suffering than wellbeing.
