What is Learned Determines How Pavlovian Conditioned Fear is Consolidated in the Brain

Author(s): Leake J; Leidl DM; Lay BPP; Fam JP; Giles MC; Qureshi OA; Westbrook RF; Holmes NM;

Activity in the basolateral amygdala complex (BLA) is needed to encode fears acquired through contact with both innate sources of danger (i.e., things that are painful) and learned sources of danger (e.g., being threatened with a gun). However, within the B ...

Slow oscillation-spindle cross-frequency coupling predicts overnight declarative memory consolidation in older adults

Author(s): Oren M Weiner

Cross-frequency coupling (CFC) between brain oscillations during non-rapid-eye-movement (NREM) sleep (e.g. slow oscillations [SO] and spindles) may be a neural mechanism of overnight memory consolidation. Declines in CFC across the lifespan might accompany ...

Danger Changes the Way the Brain Consolidates Neutral Information; and Does So by Interacting with Processes Involved in the Encoding of That Information

Author(s): Omar A Qureshi

This study examined the effect of danger on consolidation of neutral information in two regions of the rat (male and female) medial temporal lobe: the perirhinal cortex (PRh) and basolateral amygdala complex (BLA). The neutral information was the associatio ...

Sleep affects higher-level categorization of speech sounds, but not frequency encoding

Author(s): Chapelle A; Savard MA; Restani R; Ghaemmaghami P; Thillou N; Zardoui K; Chandrasekaran B; Coffey EBJ; ...

Sleep can increase consolidation of new knowledge and skills. It is less clear whether sleep plays a role in other aspects of experience-dependent neuroplasticity, which underlie important human ca ...

Sigma oscillations protect or reinstate motor memory depending on their temporal coordination with slow waves

Author(s): Nicolas J; King BR; Levesque D; Lazzouni L; Coffey EBJ; Swinnen S; Doyon J; Carrier J; Albouy G; ...

Targeted memory reactivation (TMR) during post-learning sleep is known to enhance motor memory consolidation but the underlying neurophysiological processes remain unclear. Here, we confirm the ben ...
