AhnAllen CG, Nestor PG, Shenton ME, McCarley RW, Niznikiewicz MA Schizophr. Res. 2008 Mar;100(1-3):261-9 PMID: 17884348 Abstract As cigarette smoking prevalence rates approach 90% in schizophrenia, an important emerging question is the role of nicotine in the disease-related disturbance in cognition. We therefore tested a total of 38 male cigarette… read more →
Nestor PG, Kubicki M, Kuroki N, Gurrera RJ, Niznikiewicz M, Shenton ME, McCarley RW Psychiatry Res 2007 May;155(1):21-8 PMID: 17395435 Abstract A group of 44 patients with schizophrenia and 43 age-matched controls completed psychometrically-matched tasks of recall and recognition.

AhnAllen CG, Nestor PG, McCarley RW, Shenton ME Psychiatry Res 2007 Feb;150(1):43-50 PMID: 17188366 Abstract To examine retrieval-induced forgetting (RIF) in schizophrenia, subjects studied category-exemplar words taken from either strong or weak categories, and then practiced retrieval by completing category word-stems on half of the word pairs. Patients had reduced… read more →
Walder DJ, Seidman LJ, Makris N, Tsuang MT, Kennedy DN, Goldstein JM Schizophr. Res. 2007 Feb;90(1-3):295-301 PMID: 17150336 Abstract OBJECTIVE: This pilot study investigated whether our previous findings of disrupted normal sexual brain dimorphisms in language-associated regions in schizophrenia were linked with our previously reported sex differences in language dysfunction… read more →
Nestor PG, Kubicki M, Spencer KM, Niznikiewicz M, McCarley RW, Shenton ME Schizophr. Res. 2007 Feb;90(1-3):308-15 PMID: 17150337 Abstract Thirty patients with chronic schizophrenia and 30 age-matched controls performed the Attention Network Test (ANT). A subset of the patient group (n=18) also had available magnetic resonance diffusion tensor imaging (DTI)… read more →
Goldstein JM, Seidman LJ, Makris N, Ahern T, O’Brien LM, Caviness VS, Kennedy DN, Faraone SV, Tsuang MT Biol. Psychiatry 2007 Apr;61(8):935-45 PMID: 17046727 Abstract BACKGROUND: This is a unique hypothalamic magnetic resonance imaging (MRI) study in schizophrenia, an important region in the limbic system. We hypothesized abnormal volumetric increases,… read more →
Makris N, Goldstein JM, Kennedy D, Hodge SM, Caviness VS, Faraone SV, Tsuang MT, Seidman LJ Schizophr. Res. 2006 Apr;83(2-3):155-71 PMID: 16448806 Abstract The insula is anatomically situated to be critically involved in many bio-behavioral functions impaired in schizophrenia. Furthermore, its total volume has been shown to be reduced in… read more →

Nestor PG, Valdman O, Niznikiewicz M, Spencer K, McCarley RW, Shenton ME Schizophr. Res. 2006 Feb;82(2-3):139-42 PMID: 16325376 Abstract We examined semantic vs. associational influences on word priming in schizophrenia. Tested on three occasions, subjects made speeded lexical decisions to three kinds of prime-word relationships: semantic-only (e.g., Deer-Pony), associated-only (e.g.,… read more →
Kubicki M, McCarley R, Westin CF, Park HJ, Maier S, Kikinis R, Jolesz FA, Shenton ME J Psychiatr Res 2007 Jan-Feb;41(1-2):15-30 PMID: 16023676 Abstract Both post-mortem and neuroimaging studies have contributed significantly to what we know about the brain and schizophrenia. MRI studies of volumetric reduction in several brain regions… read more →
