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. Expand
The emotional power of music: How music enhances the feeling of affective pictures
It is suggested that emotional pictures evoke a more cognitive mode of emotion perception, whereas congruent presentations of emotional visual and musical stimuli rather automatically evoke strong emotional feelings and experiences. Expand
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. Expand
Cortisol has different effects on human memory for emotional and neutral stimuli
In all memory tests, subjects who viewed the emotional story scored better for the emotionally arousing story parts, indicating that arousal enhances memory, and confirms a non-linear interaction between cortisol and arousal on memory formation. Expand
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. Expand
A whole-brain imaging-based systems approach to understand origin of addiction in binge-like drinking model
This work developed a dedicated image computational workflow to identify c-Fos-positive cells in three-dimensional images obtained after optical tissue clearing and whole-brain imaging in the light-sheet microscope and analyzed functional networks and brain modularity following reexposure to alcohol.

Altered intrinsic brain activity in patients with hepatic encephalopathy
This study suggests that alterations in the fronto‐striato‐cerebellar and visuo‐sensorimotor networks may be the potential pathophysiological mechanisms underlying HE, and deficits in the default mode network (DMN) may indicate the progression of HE. Expand
Memory and comprehension of narrative versus expository texts: A meta-analysis
A meta-analysis of experiments in which memory and/or comprehension of narrative and expository texts was investigated found that stories were more easily understood and better recalled than essays. Expand
Multiple-region grey matter atrophy as a predictor for the development of dementia in a community: the Hisayama Study
Objective To assess the association of regional grey matter atrophy with dementia risk in a general older Japanese population. Methods We followed 1158 dementia-free Japanese residents aged ≥65 yearsExpand


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 orExpand
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 showedExpand
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. Expand
The amygdala's contribution to memory—a study on two patients with Urbach-Wiethe disease
The consequences of primary amygdaloid damage on memory performance are described in terms of neuropsychological, CT, MRI and PET results of two patients, a brother and a sister. Both hadExpand
β-Adrenergic activation and memory for emotional events
SUBSTANTIAL evidence from animal studies suggests that enhanced memory associated with emotional arousal results from an activation of β-adrenergic stress hormone systems during and after anExpand
Neuromodulatory systems and memory storage: Role of the amygdala
Findings suggest that the amygdala integrates the memory-modulating effects of neuromodulatory systems activated by learning experiences, and appears to involve activation of a cholinergic system. Expand
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.

Galvanic skin response conditioning deficit in amygdalectomized monkeys.
Amygdalectomized monkeys have depressed galvanic skin responses during tests of the orienting reaction to repeated presentation of simple tones, despite normal GSR to skin stimulation. Expand
