Early-stage visual processing and cortical amplification deficits in schizophrenia.
BACKGROUND Patients with schizophrenia show deficits in early-stage visual processing, potentially reflecting dysfunction of the magnocellular visual pathway. The magnocellular system operatesExpand

Subcortical visual dysfunction in schizophrenia drives secondary cortical impairments.
Visual processing deficits are an integral component of schizophrenia and are sensitive predictors of schizophrenic decompensation in healthy adults. The primate visual system consists of discreteExpand

Growth and development in preterm infants fed long-chain polyunsaturated fatty acids: a prospective, randomized controlled trial.
OBJECTIVES A randomized, masked, controlled trial was conducted to assess effects of supplementing premature infant formulas with oils containing the long-chain polyunsaturated fatty acids,Expand

Dysfunction of early-stage visual processing in schizophrenia.
OBJECTIVE Schizophrenia is associated with deficits in higher-order processing of visual information. This study evaluated the integrity of early visual processing in order to evaluate the overallExpand

The Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19)
The purpose of the present study was to develop a reliable and valid self-report questionnaire to assess the perceived influence of Multiple Sclerosis (MS) symptoms on sexual activity andExpand

Impairments in generation of early-stage transient visual evoked potentials to magno- and parvocellular-selective stimuli in schizophrenia
OBJECTIVE Patients with schizophrenia demonstrate significant impairments of early visual processing, potentially implicating dysfunction of the magnocellular visual pathway. The present studyExpand

Intermodulation components of the visual evoked potential: Responses to lateral and superimposed stimuli
Nonlinear interactions in the human visual system were studied using visual evoked potentials (VEPs). In one experiment (superimposed condition), all segments of a dartboard pattern were contrastExpand

Asymmetries in ON and OFF visual pathways of humans revealed using contrast-evoked cortical potentials.
Positive- and negative-contrast stimuli yield the perceptions of brightness and darkness, respectively, and are processed separately by ON and OFF neural pathways. The properties of theseExpand

Rehabilitation of intimacy and sexual dysfunction in couples with multiple sclerosis
Sexual dysfunction is a highly prevalent symptom of multiple sclerosis (MS), with little published research on effective treatments. This pilot study tested the efficacy of a counseling interventionExpand
