Word Recall in Schizophrenia: A Connectionist Model
(American Psychiatric Publishing, 1998)
Objective:The authors examined word recall of patients with schizophrenia by using an experimental paradigm generated from connectionist models of memory.Method:Schizophrenic patients and normal comparison subjects first ...
Schizotypal personality disorder and MRI abnormalities of temporal lobe gray matter
(Elsevier BV, 1999)
Background: Structural MRI data indicate schizophrenics have reduced left-sided temporal lobe gray matter volumes, especially in the superior temporal gyrus (STG) and medial temporal lobe. Our data further suggest a ...
MRI anatomy of schizophrenia
(Elsevier BV, 1999)
Structural magnetic resonance imaging (MRI) data have provided much evidence in support of our current view that schizophrenia is a brain disorder with altered brain structure, and consequently involving more than a simple ...
Aberrant semantic activation in schizophrenia: a neurophysiological study
(American Psychiatric Publishing, 1997)
OBJECTIVE: Schizophrenia has long been thought to be characterized by a fundamental disturbance in semantic associations, which has often been presumed to be of neurobiological origin. The authors examined the neurophysiological ...
Superior Temporal Gyrus Volume Abnormalities and Thought Disorder in Left-Handed Schizophrenic Men
(American Psychiatric Publishing, 1999)
Objective: Studies of schizophrenia have not clearly defined handedness as a differentiating variable. Moreover, the relationship between thought disorder and anatomical anomalies has not been studied extensively in ...
Subgenual Cingulate Cortex Volume in First-Episode Psychosis
(American Psychiatric Publishing, 1999)
Objective: Gray matter volume and glucose utilization have been reported to be reduced in the left subgenual cingulate of subjects with familial bipolar or unipolar depression. It is unclear whether these findings are ...
Magnetic resonance imaging study of hippocampal volume in chronic, combat-related posttraumatic stress disorder
(Elsevier BV, 1996)
This study used quantitative volumetric magnetic resonance imaging techniques to explore the neuroanatomic correlates of chronic, combat-related posttraumatic stress disorder (PTSD) in seven Vietnam veterans with PTSD ...
ERP abnormalities during semantic processing in schizophrenia
(Elsevier BV, 1993)
To examine the neurophysiological and cognitive characteristics of thought disturbance in schizophrenic patients, we examined the amplitude, latency, and topography of a specific event-related brain potential (ERP), the ...
Cognitive dysfunction in schizophrenia: unifying basic research and clinical aspects
(Springer Science + Business Media, 1999)
Seeking to unite psychological and biological approaches, this paper links cognitive and cellular hypotheses and data about thought and language abnormalities in schizophrenia. The common thread, it is proposed, is a ...
Gamma Frequency–Range Abnormalities to Auditory Stimulation in Schizophrenia
(American Medical Association (AMA), 1999)
Background: Basic science studies at the neuronal systems level have indicated that gamma-range (30–50 Hz) neural synchronization may be a key mechanism of information processing in neural networks, reflecting integration ...
