Reward Modulation of Hippocampal Subfield Activation during Successful Associative Encoding and Retrieval
"... ■ Emerging evidence suggests that motivation enhances epi-sodic memory formation through interactions between medial-temporal lobe (MTL) structures and dopaminergic midbrain. In addition, recent theories propose that motivation specifi-cally facilitates hippocampal associative binding processes, res ..."

influenced memory. The magnitude of behavioral reward mod-ulation was associated with reward-related activation changes in dentate gyrus/CA2,3 during encoding and enhanced func-tional connectivity between dentate gyrus/CA2,3 and dopa-minergic midbrain during both the encoding and retrieval phases of the task
Elemental Spatial and Temporal Association Formation in Left Temporal Lobe Epilepsy
"... The mesial temporal lobe (MTL) is typically understood as a memory structure in clinical settings, with the sine qua non of MTL damage in epilepsy being memory impairment. Recent models, however, understand memory as one of a number of higher cognitive functions that recruit the MTL through their re ..."

Activating the medial temporal lobe during oddity judgment for faces and scenes
- Cereb. Cortex
, 2008
"... Impairments in visual discrimination beyond long-term declarative memory have been found in amnesic individuals, with hippocampal lesions resulting in deficits in scene discrimination and perirhinal cortex damage affecting object discrimination. To complement these findings, the present functional m ..."

Remote effects of hippocampal sclerosis on effective connectivity during working memory encoding: a case of connectional diaschisis? Cereb
- Cortex
, 2012
"... Accumulating evidence suggests a role for the medial temporal lobe (MTL) in working memory (WM). However, little is known concerning its functional interactions with other cortical regions in the distributed neural network subserving WM. To reveal these, we availed of subjects with MTL damage and ch ..."

and characterized changes in effective connectivity while subjects engaged in WM task. Specifically, we compared dynamic causal models, extracted from magnetoencephalographic recordings during verbal WM encoding, in temporal lobe epilepsy patients (with left hippocampal sclerosis) and controls. Bayesian model
Hemispheric Specialization During Episodic Memory Encoding in the Human Hippocampus and MTL
, 2000
"... Hemispheric specialization during episodic memory encoding was examined using three functional magnetic resonance imaging (fMRI) tasks. Stimuli for the three tasks differed in the degree to which they elicited subjects use of verbal and imagebased encoding strategies. Intentional encoding of visual ..."

Across tasks, materialspecific lateralization of neural activity was observed in the posterior mTL. In contrast, hippocampal activation did

Behavioral/Cognitive Associative Encoding and Retrieval Are Predicted by Functional Connectivity in Distinct Hippocampal Area CA1 Pathways
"... Determining how the hippocampus supports the unique demands of memory encoding and retrieval is fundamental for understanding the biological basis of episodic memory. One possibility proposed by theoretical models is that the distinct computational demands of encoding and retrieval are accommodated ..."

We found evidence for a double dissociation between the pathways supporting successful encoding and retrieval. Specifically, during the associative encoding task, but not the retrieval task, functional

"... Abstract: The brain mechanisms that enable us to form durable associations between different types of information are not completely understood. Although the hippocampus is widely thought to play a sub-stantial role in forming associations, the role of surrounding cortical regions in the medial temp ..."

Neural mechanisms of context effects on face recognition: automatic binding and context shift decrements
- Journal of Cognitive Neuroscience

"... Abstract Although people do not normally try to remember associations between faces and physical contexts, these associations are established automatically, as indicated by the difficulty of recognizing familiar faces in different contexts ("butcher-on-the-bus" phenomenon). The present fu ..."

Regionally reduced brain volume, altered serotonin neurochemistry, and abnormal behavior in mice null for the circadian rhythm output gene Magel2.

"... Magel2 belongs to the MAGE/necdin family of proteins, which have roles in cell cycle, differentiation, and apoptosis. The Magel2 gene is expressed in various brain regions, most notably the hypothalamus. Mice with a targeted deletion of Magel2 display hypoactivity, blunted circadian rhythm, decreas ..."
