Involvement of the human medial temporal lobe in a visual discrimination task
Recent imaging and lesion studies suggest that the human medial temporal lobe (including the hippocampus and the perirhinal cortex), which is traditionally believed to be of central importance for memory processing, is also involved in processing and discrimination of complex visual stimuli. The aim of this study was to use functional magnetic resonance imaging in healthy subjects to further el...
متن کاملVisual discrimination performance, memory, and medial temporal lobe function.
We evaluated recent proposals that structures in the medial temporal lobe (MTL)--in particular, perirhinal cortex--support not just memory but certain kinds of perceptual abilities as well. Specifically, it has been suggested that the perirhinal cortex supports the perceptual abilities needed to accomplish visual discrimination performance when the stimuli have complex features and overlapping ...
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 کاملA pencil rescues impaired performance on a visual discrimination task in patients with medial temporal lobe lesions.
We tested proposals that medial temporal lobe (MTL) structures support not just memory but certain kinds of visual perception as well. Patients with hippocampal lesions or larger MTL lesions attempted to identify the unique object among twin pairs of objects that had a high degree of feature overlap. Patients were markedly impaired under the more difficult task conditions. However, the deficit ...
متن کاملCan Complex Visual Discrimination Deficits in Amnesia Be Attributed to the Medial Temporal Lobe? An Investigation Into the Effects of Medial Temporal Lobe Damage on Brain Connectivity
It has been suggested that complex visual discrimination deficits in patients with medial temporal lobe (MTL) damage may be explained by damage or dysfunction beyond the MTL. We examined the resting functional networks and white matter connectivity of two amnesic patients who have consistently demonstrated discrimination impairments for complex object and/or spatial stimuli across a number of s...
