In our previous studies, we identified that exploratory eye movement (EEM) dysfunction appears to be specific to schizophrenia. The availability of a biological marker specific to schizophrenia would be useful for clinical diagnosis of schizophrenia.

This study examined the effects of subsequent, subchronic, treatment with choline uptake enhancer MKC-231 on the behavioral and cellular deficits induced by repeated PCP exposure in rats. Prior subchronic PCP exposure resulted in increased locomotion

A couple of papers indicate that patients with depression show a decrease in serum neuropeptide Y (NPY). To study the role of NPY in depression, we examined the effects of infusion of NPY into the hippocampus of learned helplessness (LH) rats (an ani

The goal of this study was to evaluate the utility of using plasma levels of amino acids as an indicator of the severity of depression. The samples were collected from 23 depressed patients receiving antidepressant medication, and were compared to 31

Learned helplessness rats are thought to be an animal model of depression. To study the role of synapse plasticity in depression, we examined the effects of learned helplessness and antidepressant treatments on synapsin I (a marker of presynaptic ter

Neurosteroids administered during the neonatal period affect the development of several brain systems. We examined the effects of neonatal treatment with pregnenolone and dehydroepiandrosterone (DHEA) on a marker of neuronal dendrites, microtubule-as

Plasma levels of ACTH, cortisol and monoamines were examined in 23 depressed patients and 31 healthy subjects. Patients showed increased plasma cortisol levels, but not plasma adrenocorticotropic hormone (ACTH) levels. The plasma levels of a dopamine

Narp (neuronal activity-regulated pentraxin) is a secreted immediate early gene product functioning as a cluster factor for the AMPA receptor subtype of glutamate receptors. This study was designed to examine the effects of acute administration of me

Learned helplessness, but not immobilization stress, decreased the numbers of neuropeptide Y (NPY)-positive cells (interneuron), but not calcitonin gene-related peptide (CGRP)-positive cells (mossy cell), in the hilus of the hippocampus. Subchronic t

It is well documented that neurosteroids administered during the neonatal period influence the development of several brain systems. In our previous study, pregnenolone administered to rats during the neonatal period altered adenosinergic and dopamin
