Dissociating intentional learning from relative novelty responses in the medial temporal lobe.
The establishment of a role for medial temporal lobe (MTL) structures in episodic memory has led to an investigative focus on the specific contributions and interactions between constituent MTL regions, including the hippocampus and surrounding medial temporal cortices. By dissociating an intentional stimulus-category learning condition from a passive viewing condition, we demonstrate, using fM...
متن کاملDissociating retrieval success from incidental encoding activity during emotional memory retrieval, in the medial temporal lobe
The memory-enhancing effect of emotion has been linked to the engagement of emotion- and memory-related medial temporal lobe (MTL) regions (amygdala-AMY; hippocampus-HC; parahippocampus-PHC), during both encoding and retrieval. However, recognition tasks used to investigate the neural correlates of retrieval make it difficult to distinguish MTL engagement linked to retrieval success (RS) from t...
متن کاملThe medial temporal lobe.
The medial temporal lobe includes a system of anatomically related structures that are essential for declarative memory (conscious memory for facts and events). The system consists of the hippocampal region (CA fields, dentate gyrus, and subicular complex) and the adjacent perirhinal, entorhinal, and parahippocampal cortices. Here, we review findings from humans, monkeys, and rodents that illum...
متن کاملEndoscopic Transsphenoidal Resection of a Medial Temporal Arachnoid Cyst in a Patient with Temporal Lobe Epilepsy
Abstract Introduction: Arachnoid cysts are developmental cystic lesions which may be found as an incidental finding on neuroimaging or present with symptoms of headache, seizure and neurologic deficit. Presentation with seizure is more common with larger sizes and temporal location. Presentation with TLE is rare, and fenestration of cysts had variable results for seizure control. Here in, we r...
متن کاملPET activation of the medial temporal lobe in learning.
Regional cerebral blood flow was examined during multiple-trial learning in healthy volunteers. On the basis that incremental learning from trial to trial is severely impaired in neuropsychological studies of patients with medial temporal lesions, we predicted that medial temporal activation might be particularly associated with incremental gains in learning. On the other hand, we predicted tha...
