Reinstatement of Item-Specific Contextual Details During Retrieval Supports Recombination-Related False Memories.

Neuroimage 2021 Apr 6:118033. Epub 2021 Apr 6.

Department of Psychology and Center for Brain Science, Harvard University.

Flexible retrieval mechanisms that allow us to infer relationships across events may also lead to memory errors or distortion when details of one event are misattributed to the related event. Here, we tested how making successful inferences alters representation of overlapping events, leading to false memories. Participants encoded overlapping associations ('AB' and 'BC'), each of which was superimposed on different indoor and outdoor scenes that were pre-exposed prior to associative learning. Read More

Stairway to memory: left-hemispheric alpha dynamics index the progressive loading of items into a short-term store.

Neuroimage 2021 Apr 6:118024. Epub 2021 Apr 6.

College of Medicine, University of Nebraska Medical Center, Omaha, NE; Institute for Human Neuroscience, Boys Town National Research Hospital, Omaha, NE.

The encoding, maintenance, and subsequent retrieval of memories over short time intervals is an essential cognitive function. Load effects on the neural dynamics supporting the maintenance of short-term memories have been well studied, but experimental design limitations have hindered the study of similar effects during the encoding of information into online memory stores. Theoretically, the active encoding of complex visual stimuli into memory must also recruit neural resources in a manner that scales with memory load. Read More

Unmasking the coronary-subclavian steal syndrome: the culprit lies in the subclavian artery. A report of a case and review of the literature.

Ann Vasc Surg 2021 Apr 6. Epub 2021 Apr 6.

Departments of Vascular Surgery. Electronic address:

The coronary-subclavian steal syndrome (CSSS) is a hemodynamic phenomenon in which a subclavian artery stenosis or occlusion impairs blood flow at the origin of the left internal mammary artery (LIMA) used for coronary artery bypass grafting (CABG), causing retrograde blood flow and thus provoking symptoms of cardiac ischemia and its complications. Once considered the gold-standard operation of choice, open revascularization has now been abandoned as a first line treatment and replaced by endovascular techniques. In all cases, detailed and oriented physical examination in combination with further imaging in high clinical suspicion for CSSS remains the sine qua non of the preoperative examination of the patient.
