This cortical stimulation mapping study investigates the neural representation of action and object naming. Data from 13 neurosurgical subjects undergoing awake cortical mapping is presented. Our findings indicate clear evidence of differential disruption of noun and verb naming in the context of this naming task. At the individual level, evidence was found for punctuate regions of perisylvian cortex subserving noun and verb function. Across subjects, however, the location of these sites varied. This finding may help explain discrepancies between lesion and functional imaging studies of noun and verb naming. In addition, an alternative coding of these data served to highlight the grammatical class vulnerability of the target response. The use of this coding scheme implicates a role for the supramarginal gyrus in verb-naming behavior. These data are discussed with respect to a functional-anatomical pathway underlying verb naming.

Background: There is growing evidence that discourse (i.e., connected speech) could serve as a cost-effective and ecologically valid means of identifying individuals with prodromal Alzheimer's disease.

Purpose: Following the Rehabilitation Treatment Specification System (RTSS) framework, the current study investigated the active ingredients in the modified semantic feature analysis (mSFA) targeting either noun or verb retrieval in Mandarin-English bilingual adults with aphasia (BWA).

Method: Twelve Mandarin-English BWA completed mSFA treatment for nouns and verbs. Eight of them completed both noun and verb treatment, while four completed either type of treatment.

Uncovering language deficits in focal epilepsy: Beyond the limits of noun naming and verbal fluency.

Background: A range of language impairments have been reported in people with epilepsy both pre- and post-surgically, however language is not routinely comprehensively assessed in epilepsy clinics. When language is assessed, this is typically as part of a broader neuropsychological battery of assessment, often limited to tests of noun naming and/or verbal fluency, despite evidence to suggest these tests are not sufficiently sensitive to detect the often-subtle deficits present in chronic focal epilepsy. Many areas of language function, including the production of connected speech, have also not been adequately explored in this population, and research relating to subjective report of language and communication difficulties is limited.

Purpose: The current study aimed to examine the linguistic characteristics of Korean-speaking individuals diagnosed with primary progressive aphasia(PPA).

Methods: Two individuals with agrammatic/non-fluent variants of nfvPPA and two with semantic variants of svPPA participated in this study. Picture description tasks were used to collect connected speech samples.

Comprehenders generate expectations about upcoming lexical items in language processing using various types of contextual information. However, a number of studies have shown that argument roles do not impact neural and behavioral prediction measures. Despite these robust findings, some prior studies have suggested that lexical prediction might be sensitive to argument roles in production tasks such as the cloze task or in comprehension tasks when additional time is available for prediction.
