The dorsolateral prefrontal cortex in idiom interpretation: An rTMS study

Brain Research Bulletin, 2007
Neuropsychological studies have suggested that a prefrontal lesion can impair idiom comprehension. We tested the role of the dorsolateral prefrontal cortex (DLPFC) in idiom processing by using repetitive transcranial magnetic stimulation (rTMS) in normal participants. Each subject was presented with a written (idiomatic or literal) sentence followed by

The role of the mid-dorsolateral prefrontal cortex in working memory

Experimental Brain Research, 2000
Recent studies with nonhuman primates have shown that lesions of the mid-dorsolateral prefrontal cortex, which extends from the lip of the dorsal bank of the sulcus principalis to the midline (i.e., dorsal area 46 and 9/46 and area 9), give rise to severe and long-lasting impairments on self-ordered and externally ordered tasks designed to tax ...

Discourse production following injury to the dorsolateral prefrontal cortex

Neuropsychologia, 2012
Individuals with damage to the prefrontal cortex, and the dorsolateral prefrontal cortex (DLPFC) in particular, often demonstrate difficulties with the formulation of complex language not attributable to aphasia. The present study employed a discourse analysis procedure to characterize the language of individuals with left (L) or right (R) DLPFC ...

Molecular and cellular evolution of the primate dorsolateral prefrontal cortex

Science, 2022
The granular dorsolateral prefrontal cortex (dlPFC) is an evolutionary specialization of primates that is centrally involved in cognition. We assessed more than 600,000 single-nucleus transcriptomes from adult human, chimpanzee, macaque, and marmoset dlPFC.

Mapping cortical excitability in the human dorsolateral prefrontal cortex

Clinical Neurophysiology, 2023
ABSTRACT Objective To characterize early TEPs anatomically and temporally (20-50 ms) close to the TMS pulse (EL-TEPs), as well as associated muscle artifacts (<20 ms), across the dlPFC. We hypothesized that TMS location and angle influence EL-TEPs, and that EL-TEP amplitude is inversely related to

Dorsolateral prefrontal cortex sensitivity to rTMS

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
This paper presents the preliminary results of a study to determine dorsolateral prefrontal cortex sensitivity to rTMS stimulation presented at clinically accepted amplitudes, frequencies and locations. A specially developed EEG system with 10-20 electrode locations was used to record the short latency magnetically evoked potentials.

A subsequent-memory effect in dorsolateral prefrontal cortex

Cognitive Brain Research, 2003
The importance of brain regions for long-term memory encoding has been examined by comparison of encoding-related neural activity on trials in which successful recollection subsequently occurred to the encoding-related activity on trials in which successful recollection did not occur.

Auditory memory cells in dorsolateral prefrontal cortex

NeuroReport, 1996
The activity of single neurons was recorded extracellularly from dorsolateral prefrontal cortex (DPC) of monkeys during the performance of a cross-modal audio-visual short-term memory task. Cells in DPC show sustained elevated firing levels (higher than spontaneous discharge) during the retention of the auditory stimulus.

A dorsolateral prefrontal cortex semi-automatic segmenter

SPIE Proceedings, 2006
Structural, functional, and clinical studies in schizophr enia have, for several decades, consistently implicateddysfunction of the prefrontal cortex in the etiology of the disease. Functional and structural imaging stud-ies, combined with clinical, psychometric, and genetic analyses in schizophrenia have con“rmed the key rolesplayed by the prefrontal ...

Reliability of the TMS-evoked potential in dorsolateral prefrontal cortex

Cerebral Cortex, 2023
Abstract Background We currently lack a robust and reliable method to probe cortical excitability noninvasively from the human dorsolateral prefrontal cortex (dlPFC), a region heavily implicated in psychiatric disorders.
