2020 Frontiers in Systems Neuroscience  
The present study showed for the first time the successful prediction with high accuracy of subsequent memory outcome using single-trial functional connectivity.  ...  However, as multiple brain regions work collaboratively to process memory, it could be a better option to use functional connectivity within the memory-related brain network to predict subsequent memory  ...  ACKNOWLEDGMENTS We thank Hong Jun Kim for assistance with the EEG experiments.  ...

Altered alpha/beta desynchronization during item–context binding contributes to the associative deficit in older age

Anna E Karlsson, Myriam C Sander
2022 Cerebral Cortex  
Single-trial theta power could not predict subsequent item memory, but predicted pair memory in an age-invariant manner, in line with a mechanism supporting associative memory.  ...  In contrast, single-trial alpha/beta power predicted both item and pair memory, in line with a mechanism reflecting the depth of information processing, and predicted pair memory less well in the older  ...  Acknowledgements Data collection and analysis was conducted within the projects Lifespan Age Differences in Memory Representations (LIME) (PI: MCS) and Lifespan Rhythms of Memory and Cognition (RHYME)  ...

Intracranial EEG Correlates of Expectancy and Memory Formation in the Human Hippocampus and Nucleus Accumbens

Nikolai Axmacher, Michael X. Cohen, Juergen Fell, Sven Haupt, Matthias Dümpelmann, Christian E. Elger, Thomas E. Schlaepfer, Doris Lenartz, Volker Sturm, Charan Ranganath
2010 Neuron  
Recordings from the nucleus accumbens revealed a late potential (peak at 475 ms), which increases in magnitude during unexpected items, but no subsequent memory effect and no early component.  ...  Unexpected events are more likely to be remembered than predictable events, but the underlying neural mechanisms for these effects remain unclear.  ...  Participants were subsequently tested on memory for the expected and unexpected items from each list, allowing us to examine encoding activity as a function of subsequent memory performance.  ...

The Role of Meaning in Visual Memory: Face-Selective Brain Activity Predicts Memory for Ambiguous Face Stimuli

Timothy F. Brady, George A. Alvarez, Viola S. Störmer
2018 Journal of Neuroscience  
In particular, we use single-trial EEG activity to predict whether an image will be subsequently remembered, and show that the main driver of this prediction ability is whether or not an image is seen  ...  We show in adult humans of either sex that single trial EEG activity can predict whether participants will subsequently remember an ambiguous Mooney face image (e.g., an image that will sometimes be seen  ...  Thus, a classifier trying only to predict whether a stimulus is a face or non-face predicts subsequent memory for ambiguous faces even using only single-trial EEG data.  ...

Cerebellar theta and beta noninvasive stimulation rhythms differentially influence episodic memory versus language [article]

Shruti Dave, Stephen VanHaerents, Joel Voss
2020 biorxiv/medrxiv   pre-print
The cerebellum is thought to interact with distributed brain networks to support cognitive abilities such as episodic memory and language.  ...  Episodic memory and language networks have been associated with distinct endogenous oscillatory activity frequency bands: theta (~3-8 Hz) versus beta (~13-30 Hz), respectively.  ...  To ensure roughly equal trials across stimulation conditions, we analyzed late-positive ERP amplitude for all single-word encoding trials regardless of subsequent recognition performance (Fig. 5) .  ...

Oscillatory Mechanisms of Successful Memory Formation in Younger and Older Adults Are Related to Structural Integrity

2019 Cerebral Cortex  
While older adults showed lower memory performance than young adults, we found subsequent memory effects (SME) in alpha/beta and theta frequency bands in both age groups.  ...  Thus, our results suggest that differences in the structural integrity of the IFG contribute not only to interindividual, but also to age differences in memory formation.  ...  We are also grateful to Julia Delius for editorial assistance. Conflict of Interest: The authors declare no conflicts of interests.  ...

2007 Journal of Neuroscience  
Here, we exploit intracranial EEG to identify WM-specific sustained activity patterns with the highest temporal and spatial resolution currently available in humans.  ...  Using a serial Sternberg paradigm, we found a positive shift of the direct current (DC) potential and a long-lasting decrease in MTL gamma-band activity during maintenance of a single item, reflective  ...  Encoding of multiple items (trials with four faces) To verify whether the memory-load dependent DC potentials already build up during the presentation of subsequent stimuli, we analyzed mean values and  ...
