First-pass selectivity for semantic categories in human anteroventral temporal lobe.
How the brain encodes the semantic concepts represented by words is a fundamental question in cognitive neuroscience. Hemodynamic neuroimaging studies have robustly shown that different areas of posteroventral temporal lobe are selectively activated by images of animals versus manmade objects. Selective responses in these areas to words representing animals versus objects are sometimes also see...
متن کاملProcessing stages underlying word recognition in the anteroventral temporal lobe.
The anteroventral temporal lobe integrates visual, lexical, semantic and mnestic aspects of word processing, through its reciprocal connections with the ventral visual stream, language areas, and the hippocampal formation. We used linear microelectrode arrays to probe population synaptic currents and neuronal firing in different cortical layers of the anteroventral temporal lobe, during semanti...
متن کاملDisrupted temporal lobe connections in semantic dementia.
Semantic dementia refers to the variant of frontotemporal dementia in which there is progressive semantic deterioration and anomia in the face of relative preservation of other language and cognitive functions. Structural imaging and SPECT studies of such patients have suggested that the site of damage, and by inference the region critical to semantic processing, is the anterolateral temporal l...
متن کاملSemantic memory is impaired in patients with unilateral anterior temporal lobe resection for temporal lobe epilepsy.
Contemporary clinical and basic neuroscience studies have increasingly implicated the anterior temporal lobe regions, bilaterally, in the formation of coherent concepts. Mounting convergent evidence for the importance of the anterior temporal lobe in semantic memory is found in patients with bilateral anterior temporal lobe damage (e.g. semantic dementia), functional neuroimaging and repetitive...
متن کاملComparison of temporal lobe epilepsy with hippocampal sclerosis and temporal lobe epilepsies due to other etiologies
Background: This study compares the clinical characteristics of patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) with those who have temporal lobe epilepsy (TLE) due to other etiologies. Methods : In this retrospective study all patients with a clinical diagnosis of TLE were recruited in a referral outpatient epilepsy clinic at Shiraz University of Medical Sc...
