How arousal modulates memory: Disentangling the effects of attention and retention

The results indicate that arousal supports slower forgetting even when the difference in attentional resources allocated to stimuli is minimized.

Amygdala volume in major depressive disorder: a meta-analysis of magnetic resonance imaging studies

Findings are consistent with a formulation in which an antidepressant-mediated increase in levels of brain-derived neurotrophic factor promotes neurogenesis and protects against glucocorticoid toxicity in the amygdala in medicated but not in unmedicated depression.

Event-related potentials of emotional memory: Encoding pleasant, unpleasant, and neutral pictures

The subsequent memory effect at centroparietal electrodes was greater for emotional pictures than for neutral pictures during an early epoch, which suggests that emotional information has privileged access to processing resources, possibly leading to better memory formation.

Opiate Withdrawal and Conditioned Withdrawal Enhance Consolidation of Object Memory in Male Sprague-Dawley Rats

It was demonstrated that 3 mg/kg naltrexone enhanced memory in morphine-maintained rats when administered immediately but not 6 h post-sample, and conditioned withdrawal could also alter memory.

Direct electrical stimulation of the amygdala enhances declarative memory in humans

It is shown that brief electrical stimulation to the human amygdala can enhance declarative memory for specific images of neutral objects without eliciting a subjective emotional response, and that the amygdala can initiate endogenous memory prioritization processes in the absence of emotional input.

Preserved and Impaired Emotional Memory in Alzheimer’s Disease

It is argued that the EEE could be a useful paradigm to reduce impairment in episodic memory tasks, according to which a compensatory mechanism in patients with AD solicits greater amygdala functioning or additional networks, even when amygdala atrophy is present.

Noradrenergic–glucocorticoid mechanisms in emotion-induced amnesia: from adaptation to disease

Immediate pharmacological blockade of noradrenergic–glucocorticoid signaling might prove effective in the secondary prevention of PTA and PTSD.

Affective Tasks Elicit Material-Specific Memory Effects in Temporal Lobectomy Patients

A strong interpretaion of the present data is made difficult by task differences and the low average IQ and possible reorganization of function that may have occurred in the patient sample.

Olfaction, Emotion & the Amygdala: arousal-dependent modulation of long-term autobiographical memory and its association with olfaction: beginning to unravel the Proust phenomenon?

Current understanding of higher olfactory information processing as it relates to the ability of odours to spontaneously cue highly vivid, affectively toned, and often very old autobiographical memories (episodes known anecdotally as Proust phenomena) is analyzed.



Double dissociation of conditioning and declarative knowledge relative to the amygdala and hippocampus in humans

A patient with selective bilateral damage to the amygdala did not acquire conditioned autonomic responses to visual or auditory stimuli but did acquire the declarative facts about which visual or

Face processing impairments after amygdalotomy

We report an investigation of face processing impairments in D.R., a 51-year-old woman with a partial bilateral amygdalotomy. D.R. was able to recognize pre-operatively familiar faces, but she showed

The amygdala's contribution to memory—a study on two patients with Urbach-Wiethe disease

The results suggest that the amygdaloid region is a bottle-neck structure that confers an affective flavour to memories, thereby enhancing the probability of their long term storage.

Neuropsychological correlates of bilateral amygdala damage.

An extensive neuropsychological investigation in a patient with bilateral amygdala damage due to Urbach-Wiethe disease showed that she had normal electrodermal activity, an important finding in view of the role that has been attributed to the amygdala in the central control of autonomic responses.

Impaired recognition of emotion in facial expressions following bilateral damage to the human amygdala

Findings suggest the human amygdala may be indispensable to recognize fear in facial expressions, but is not required to recognize personal identity from faces, and constrains the broad notion that the amygdala is involved in emotion.

β-Adrenergic activation and memory for emotional events

The impairment of propranolol on memory of the emotional story was not due either to reduced emotional responsiveness or to nonspecific sedative or attentional effects, which support the hypothesis that enhanced memory associated with emotional experiences involves activation of the β-adrenergic system.
