Hippocampal Reactivation Trades Episodic Detail for Semantic Gist in Human Memory

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractMemory must balance preserving episode-specific details with extracting generalizable structure. Here, we test whether spontaneous hippocampal reactivation during postencoding rest actively transforms memories by strengthening semantic gist at the expense of...

Distinct Patterns of Directed Brain Connectivity in Focused Attention, Open Monitoring, and Loving Kindness Meditation: An Electroencephalographic Granger Causality Study with Long-term Meditators

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractThe present study applied spectral Granger causality (GC) analysis to EEG recordings obtained during focused attention meditation (FAM), open monitoring meditation (OMM), and loving kindness meditation (LKM) in highly experienced meditators. The aim of the...

Endogenous Theta as a Function of Task Load and Working Memory Capacity: Revisiting the Role of Slower Frequencies in Theta–Gamma Coupling

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractRecent findings have shown the influential role of theta–gamma cross-frequency coupling in the maintenance of items in working memory (WM). Specifically, it has been proposed that individual items are represented within gamma oscillations that are nested...

Spatial Grouping Modulates the Link between Individual Alpha Frequency and Temporal Integration Windows in Crowding

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractPrevious research has linked endogenous alpha oscillations (∼7–13 Hz) to temporal integration windows in visual perception, with higher individual alpha frequency predicting improved temporal segregation. Here, we investigated whether alpha-rhythmic temporal...

Synergistic Short-Term Synaptic Plasticity Mechanisms for Working Memory

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractWorking memory (WM) is essential for almost every cognitive task. The neural and synaptic mechanisms supporting the rapid encoding and maintenance of memories in diverse tasks are the subject of an ongoing debate. The traditional view of WM as stationary...

Neural Correlates of Local and Global Prediction Errors Show Similar Linear Age-related Decline But Differential Associations with Working Memory

by Clinical Neuropsychologist Online | Saturday, August 1, 2026 | Cognitive Neuropsychology

AbstractSenescence is accompanied by decreased weighting of sensory inputs and increased reliance on predictions, resulting in the attenuation of prediction errors in older age. However, little is known about how the attenuation develops across adulthood. To delineate...
