Arousal and memory

Arousal-Biased Competition in Perception and Memory.

Our everyday surroundings besiege us with information. The battle is for a share of our limited attention and memory, with the brain selecting the winners and discarding the losers. Previous research shows that both bottom-up and top-down factors bias competition in favor of high priority stimuli. We propose that arousal during an event increases this bias both in perception and in long-term me...

Remembering pictures: pleasure and arousal in memory.

Incidental memory performance for pictures that varied along the affective dimensions of pleasantness and arousal was assessed. For both an immediate and delayed (1 year later) free-recall task, only the arousal dimension had a stable effect on memory performance: Pictures rated as highly arousing were remembered better than low-arousal stimuli. This effect was corroborated in a speeded recogni...

Effects of gabaergic and morphinergic systems in CA1 nucleus on anxiety and arousal memory based on test-retest paradigm

Hippocampus is a key structure in anxiety processing and memory storage. The purpose of this study was to investigate the interaction between GABAergic systems in CA1 area of hippocampus with morphinergic system in modulating of these behaviors. In this study, male wistar rats were cannulated with stereotaxic surgery in CA1 site. After a recovery period, morphine (µ opioid receptor agonist) was...

Emotional memory: From affective relevance to arousal.

Arousal is typically conceived as a key component of emotional response. We describe here the psychological processes thought to elicit arousal - in particular, the processes involved in the appraisal of affective relevance. The key role of relevance in attentional and memory processing, and its links with arousal, is discussed with respect to the GANE (glutamate amplifies noradrenergic effects...
