Memory Encoding Model

Huzheng Yang, James C. Gee, Jianbo Shi · arXiv (Cornell University) · 2023

We explore a new class of brain encoding model by adding memory-related information as input. Memory is an essential brain mechanism that works alongside visual stimuli. During a vision-memory cognitive task, we found the non-visual brain is largely predictable using previously seen images. Our Memory Encoding Model (Mem) won the Algonauts 2023 visual brain competition even without model ensemble (single model score 66.8, ensemble score 70.8). Our ensemble model without memory input (61.4) can also stand a 3rd place. Furthermore, we observe periodic delayed brain response correlated to 6th-7th prior image, and hippocampus also showed correlated activity timed with this periodicity. We conjuncture that the periodic replay could be related to memory mechanism to enhance the working memory.

Encoding neural memory

Gerard Marx, Chaim Gilon · Frontiers in Drug Chemistry and Clinical Research · 2021

In the interest of elucidating neural processes underlying memory, many have looked to computer information-theory and code, despite that these are inherently "demotive" i.e. lacking emotive qualities that render "meaning" or "value" to conscious experience. We review various textual coding schemes (i.e. Morse, Bar, QR) and consider their relevance to neural coding of "memory".

EEG power Memory encoding Memory retrieval

Kimberly Cuevas, Vinaya Raj, Martha Ann Bell · 2011

Research on the functional meaning of EEG frequency bands during memory processing has only examined two developmental periods: infancy and from late childhood to adulthood. The purpose of this study was to examine changes in EEG power for three toddler EEG frequency bands (3–5 Hz, 6–9 Hz, 10–12 Hz) during a verbal recall task. To this end, we asked three questions: (a) Which frequency band(s) discriminate baseline from memory processing?; (b) Which frequency band(s) differentiate between memory encoding and re-trieval processes?; (c) Which frequency band(s) distinguish toddlers with high and low verbal recall perfor-mance? Analysis of 2-year-olds ’ (n=79) power values revealed that all three frequency bands differentiated the retrieval and encoding phases from the baseline phase; however, the particular regions that exhibited this dissociation varied. Retrieval-related increases in 3–5 Hz (theta) power were widespread. Only the 3–5 Hz and 6–9 Hz bands distinguished encoding and retrieval processes; retrieval power values were higher than encoding power values. High and low verbal recall performers were discriminated by all frequency bands; high performers had greater power values than low performers. Thus, the 3–5 Hz (theta) and 6–9 Hz (alpha) bands were most informative about 2-year-olds’memory processes. Theta and alpha rhythms are critical to memory processes during late childhood and adulthood, and our findings provide initial evi-dence that these rhythms are also intricately linked to memory processing during toddlerhood. These find-ings are discussed in relation to behavioral changes in memory processes. © 2011 Elsevier B.V. All rights reserved. 1.

Semantic Encoding Memory Task

Guimond, Synthia, Lepage, Martin, Lavigne, Katie M. · OSF Preprints (OSF Preprints) · 2023

The Semantic Encoding Memory Task (SEMT) assesses verbal episodic memory and distinguishes between the use of semantic and non-semantic strategies.

Human Memory Encoding and Orchestration

Deng, Jiatai · Figshare · 2020

Given the ethical and linguistic constrains on human memory research, theoretical exploration plays an indispensable role. In this theoretical study, a novel framework for memory encoding and orchestration is developed as follows: All human memories are physically encoded by meaningful synaptic pairs, which indivisibly constitute the smallest memory unit capable of encoding memories regardless of synaptic strength and maturity state. Memories of the same category are hierarchically orchestrated into the smallest memory islet, which is a pyramid architecture dominated by a language-based abstract concept at the apex. Following encoding in situ, successful cross-indexing in hippocampus guides the integration of fresh memories into the islet and concomitantly triggers biochemical cascades characterized by alternate protein synthesis and degradation.

Response Conflict and Memory Encoding

Janina Habenicht, Eda Aylin Baytin, Lea Brosig et al. · OSF Preprints (OSF Preprints) · 2017

We investigate whether memory encoding of stimuli presented in a Simon task differs between those presented in conflict trials compared to those during congruent trials.
