Bayesian model selection favors parametric over categorical fMRI subsequent memory models in young and older adults

open access: yesNeuroImage, 2021
Subsequent memory paradigms allow to identify neural correlates of successful encoding by separating brain responses as a function of memory performance during later retrieval.

Encoding false memories [PDF]

open access: yesScience, 2016
Brain Research A unique human ability is the use of concepts that confer meaning in an abstract way. Despite the importance of conceptual knowledge for human cognition, scientists know little about the underlying neural mechanisms and structures. To better understand this process, Chadwick et al. scanned people's brains while they performed tasks known

Large-scale network integration in the human brain tracks temporal fluctuations in memory encoding performance

open access: yeseLife, 2018
Although activation/deactivation of specific brain regions has been shown to be predictive of successful memory encoding, the relationship between time-varying large-scale brain networks and fluctuations of memory encoding performance remains unclear ...

Stairway to memory: Left-hemispheric alpha dynamics index the progressive loading of items into a short-term store

open access: yesNeuroImage, 2021
The encoding, maintenance, and subsequent retrieval of memories over short time intervals is an essential cognitive function. Load effects on the neural dynamics supporting the maintenance of short-term memories have been well studied, but experimental ...

A pathway for spatial memory encoding [PDF]

open access: yesLearning & Behavior, 2016
The medial prefrontal cortex has been shown to play a role for rodents in successful completion of tasks that require spatial memory, but the pathways responsible for the transmission of spatial information to the mPFC, and the nature and timing of such information, are unknown. Recently, Spellman, Rigotti, Ahmari, Fusi, Gogos, and Gordon (Nature, 522,

Effects of acute methamphetamine on emotional memory formation in humans: encoding vs consolidation. [PDF]

open access: yesPLoS ONE, 2015
Understanding how stimulant drugs affect memory is important for understanding their addictive potential. Here we examined the effects of acute d-methamphetamine (METH), administered either before (encoding phase) or immediately after (consolidation ...

Perceptual implicit memory requires attentional encoding [PDF]

open access: yesMemory & Cognition, 1999
Perceptual implicit memory for previously attended and unattended words was measured either in a word-stem completion task or in a perceptual fluency (perceptual identification) task. Subjects (N = 144) first engaged in a focused attention task in which they were to identify one of two words presented for 100, 200, or 300 msec. Words were classified as

Post-encoding positive emotion impairs associative memory for English vocabulary.

open access: yesPLoS ONE, 2020
There is evidence that emotion induced during encoding impairs associative memory (e.g., Bisby, Horner, Bush, & Burgess, 2018), yet the effect of post-encoding emotion (particularly positive emotion) on associative memory remains largely unclear.

Pavlovian fear conditioning activates a common pattern of neurons in the lateral amygdala of individual brains. [PDF]

open access: yesPLoS ONE, 2011
Understanding the physical encoding of a memory (the engram) is a fundamental question in neuroscience. Although it has been established that the lateral amygdala is a key site for encoding associative fear memory, it is currently unclear whether the ...

Distinct medial-tempora lobe mechanisms of encoding and amygdala-mediated memory reinstatement for disgust and fear

open access: yesNeuroImage, 2022
Current models of episodic memory posit that retrieval involves the reenactment of encoding processes. Recent evidence has shown that this reinstatement process – indexed by subsequent encoding-retrieval similarity of brain activity patterns - is related
