Nestor PG, O’Donnell BF, McCarley RW, Niznikiewicz M, Barnard J, Jen Shen Z, Bookstein FL, Shenton ME Schizophr. Res. 2002 Jan;53(1-2):57-66 PMID: 11728838 Abstract We applied partial least squares (PLS) as a novel multivariate statistical technique to examine neuropsychological correlates of magnetic resonance imaging (MRI) measures of brain volumes in… read more →
Nestor PG, Han SD, Niznikiewicz M, Salisbury D, Spencer K, Shenton ME, McCarley RW Biol Psychol 2001 Jul-Aug;57(1-3):23-46 PMID: 11454433 Abstract We view schizophrenia as producing a failure of attentional modulation that leads to a breakdown in the selective enhancement or inhibition of semantic/lexical representations whose biological substrata are widely… read more →
Salisbury DF, Shenton ME, Nestor PG, McCarley RW Clin Neurophysiol 2002 Mar;113(3):383-95 PMID: 11897539 Abstract OBJECTIVES: It is controversial whether a semantic processing bias for strong associates is present in schizophrenia, and unknown whether the language abnormalities observed in schizophrenia can be attributed to dysfunctions early or late in cognitive… read more →
Wible CG, Anderson J, Shenton ME, Kricun A, Hirayasu Y, Tanaka S, Levitt JJ, O’Donnell BF, Kikinis R, Jolesz FA, McCarley RW Psychiatry Res 2001 Nov;108(2):65-78 PMID: 11738541 Abstract The present study measured prefrontal cortical gray and white matter volume in chronic, male schizophrenic subjects who were characterized by a… read more →
Kubicki M, Westin CF, Maier SE, Frumin M, Nestor PG, Salisbury DF, Kikinis R, Jolesz FA, McCarley RW, Shenton ME Am J Psychiatry 2002 May;159(5):813-20 PMID: 11986136 Abstract OBJECTIVE: Disruptions in connectivity between the frontal and temporal lobes may explain some of the symptoms observed in schizophrenia. Conventional magnetic resonance… read more →
Anderson JE, Wible CG, McCarley RW, Jakab M, Kasai K, Shenton ME Schizophr. Res. 2002 Dec;58(2-3):123-34 PMID: 12409152 Abstract Previous magnetic resonance imaging (MRI) studies have reported various subtle brain abnormalities in schizophrenic patients, including temporal lobe abnormalities, which are of particular interest given the role of this brain region… read more →
Salisbury DF, Shenton ME, Griggs CB, Bonner-Jackson A, McCarley RW Arch. Gen. Psychiatry 2002 Aug;59(8):686-94 PMID: 12150644 Abstract BACKGROUND: Mismatch negativity (MMN) is an event-related brain potential that is sensitive to stimulus deviation from a repetitive pattern. The MMN is thought primarily to reflect the activity of sensory memory, with,… read more →
Anderson JE, O’Donnell BF, McCarley RW, Shenton ME Restor. Neurol. Neurosci. 1998 Jun;12(2-3):175-84 PMID: 12671313 Abstract Schizophrenia is a disorder characterized by multiple symptoms, with a varied course and outcome. The etiology is yet unknown, but multiple pathological processes or, equally likely, a unique pathophysiological process, may be involved. Here,… read more →
O’Donnell BF, Potts GF, Nestor PG, Stylianopoulos KC, Shenton ME, McCarley RW J Abnorm Psychol 2002 Nov;111(4):620-5 PMID: 12428775 Abstract Pathways within the visual system can be distinguished on the basis of selectivity for low or high spatial frequencies. Spatial frequency discrimination was evaluated in 17 medicated male patients with… read more →
Han SD, Nestor PG, Shenton ME, Niznikiewicz M, Hannah G, McCarley RW Schizophr. Res. 2003 Jun;61(2-3):255-63 PMID: 12729877 Abstract We developed a computer model to simulate associative memory recall of patients with chronic schizophrenia. Model inputs consisted of words derived from normative data that differed in terms of connectivity and… read more →
