Journal ArticleDOI
The Enigmatic temporal pole: a review of findings on social and emotional processing.
TL;DR: It is proposed that the temporal pole binds complex, highly processed perceptual inputs to visceral emotional responses, which means that the integration of emotion with perception is channel specific.
Journal ArticleDOI
What Constitutes an Episode in Episodic Memory
Youssef Ezzyat,Lila Davachi +1 more
TL;DR: Functional imaging data revealed that, across participants, brain activity consistent with the ongoing integration of information within events correlated with this pattern of mnemonic segmentation, the first to address the mechanisms that support the organization of experiences into episodes in long-term memory.
Journal ArticleDOI
Similarity breeds proximity: pattern similarity within and across contexts is related to later mnemonic judgments of temporal proximity.
TL;DR: It is found that hippocampal pattern similarity in the BOLD response across trials predicted later temporal memory decisions when context changed, providing evidence in humans that representational stability in hippocampus across time may be a mechanism for temporal memory organization.
Journal ArticleDOI
Closed-loop stimulation of temporal cortex rescues functional networks and improves memory.

TL;DR: A closed-loop system is used to decode and stimulate periods of ineffective encoding, showing that stimulation of lateral temporal cortex can enhance memory and suggesting that such systems may provide a therapeutic approach for treating memory dysfunction.
Journal ArticleDOI
Episodic sequence memory is supported by a theta–gamma phase code
TL;DR: The results provide compelling evidence that memory for order, a core component of an episodic memory, capitalizes on the ubiquitous physiological mechanism of theta–gamma phase–amplitude coupling.
