Spread of activity in thick cortical slices
Brain Research, 1984Slices of the hamster cerebral cortex 700-800 micron thick have been demonstrated to be viable when maintained in a bath perfused with oxygenated CSF at 30 ml/min. In such thick slices activity has been shown to spread over both hemispheres following stimulation of the corpus callosum; and seizure activity, suggestive of epilepsy, can be induced by the

Abnormalities of cortical thickness in postictal psychosis
Epilepsy & Behavior, 2011Postictal psychosis (PIP), the occurrence of psychotic episodes following a seizure, is a common and serious comorbidity in patients with epilepsy. Yet, the anatomical correlates remain poorly defined. Here, we used quantitative MRI morphometry to identify structural abnormalities in the cortex of patients with PIP relative to patients with epilepsy ...

Cortical surface area and cortical thickness in the precuneus of adult humans
Neuroscience, 2015The precuneus has received considerable attention in the last decade, because of its cognitive functions, its role as a central node of the brain networks, and its involvement in neurodegenerative processes. Paleoneurological studies suggested that form changes in the deep parietal areas represent a major character associated with the origin of the ...

Extraction of the cerebral cortical boundaries from MRI for measurement of cortical thickness
SPIE Proceedings, 2005Several neurodegenerative diseases, such as Alzheimer's disease, cause atrophy of the cerebral cortex. Measurements of cerebral cortical thickness and volume are used in the quantification and localization of atrophy. It is possible to measure the thickness of the cerebral cortex manually from magnetic resonance imaging, but partial volume effects ...

Cognitive Predictors of Cortical Thickness in Healthy Aging
2018This study seeks to define the role of predictive values of the motor speed, inhibition control, and fluid and crystallized intelligence in estimating the cortical thickness in healthy elderly. Forty-six older healthy subjects (37 women, 9 men) over 60 years of age were included in the study. The participants were examined on 3.0 T MRI scanners.

Musical deficits and cortical thickness in people with schizophrenia
Schizophrenia Research, 2018Investigation of acquired amusia caused by brain damage suggested that cortical lesions of the right hemisphere contributed to musical deficits. We previously reported reduced musical ability in schizophrenia; these deficits were correlated with clinical manifestations such as cognitive dysfunction and negative symptoms.

Cortical thickness abnormality in juvenile myoclonic epilepsy
Journal of Neurology, 2008Previous studies on gray matter concentration changes in patients with juvenile myoclonic epilepsy (JME) are inconsistent. To investigate cortical abnormality in JME differently, we measured the cortical thickness in 19 JME patients and 18 normal controls. Results showed that the cortical thicknesses of superior/middle/medial frontal gyri, and superior/
