Foreword Dear colleague, (2008)
Tonmoy Sharma, Louise Guest, Tom Burns
The past few years have seen exponential growth in the psychopharmacology of schizophrenia. Rapid expansion in the number of therapeutic agents available to the practicing psychiatrist, coupled with...

Background: Local alterations in morphological parameters are poorly characterized in several brain regions widely implicated in schizophrenia neuropathology. Methods: Surface-based anatomical...
Cognitive enhancement in schizophrenia with pharmacological interventions (2006)
No abstract available.
Halari, Rozmin, Mehrotra, Ravi, Sharma, Tonmoy, Kumari, Veena
Symptoms are known to account for a small variance in some cognitive functions in schizophrenia, but the influence of self-perceived mood remains largely unknown. The authors examined the influence...

Kumari, Veena, Ettinger, Ulrich, Crawford, Trevor J., Zachariah, Elizabeth, Sharma, Tonmoy
Individuals with schizophrenia, compared to healthy individuals, are known to exhibit deficient prepulse inhibition (PPI) of the startle response as well as reduced performance on the antisaccade...
Structural neural correlates of prosaccade and antisaccade eye movements in healthy humans. (2005)
Ettinger, Ulrich, Antonova, Elena, Crawford, Trevor J., Mitterschiffthaler, Martina T., Goswani, Sanchayita, Sharma, Tonmoy, ...
We previously reported that prosaccade amplitude gain and antisaccade error rate are correlated with cerebellar and posterior frontal grey matter volume, respectively. This study sought to replicate...
Saccadic eye movements, schizotypy, and the role of neuroticism. (2005)
Ettinger, Ulrich, Kumari, Veena, Crawford, Trevor J., Flak, Vanja, Sharma, Tonmoy, Davis, Robert E., ...
We investigated the relationships of anti- and prosaccades with psychometric schizotypy. One aim was to estimate the role of negative emotionality and general psychopathology (i.e. neuroticism) in...
Volumetric neural correlates of antisaccade eye movements in first-episode psychosis. (2004)
Ettinger, Ulrich, Kumari, Veena, Chitnis, Xavier A., Corr, Philip J., Crawford, Trevor J., Fannon, Dominic G., ...
OBJECTIVE: The authors investigated the structural brain correlates of antisaccade performance. METHOD: Magnetic resonance imaging was used to measure the volumes of the prefrontal, premotor,...
Smooth pursuit and antisaccade eye movements in siblings discordant for schizophrenia. (2004)
Ettinger, Ulrich, Kumari, Veena, Crawford, Trevor J., Corr, Philip J., Das, Mrigendra, Zachariah, Elizabeth, ...
Smooth pursuit eye movement (SPEM) and antisaccade deficits have been proposed as endophenotypes in the search for schizophrenia genes. We assessed these measures in 24 schizophrenia patients, 24 of...

Neurological soft signs (NSS) are nonspecific indicators of brain dysfunction that are found to be in excess and correlated with cognitive dysfunction and psychopathology in patients with...
Effects of Procyclidine on Eye Movements in Schizophrenia. (2003)
Ettinger, Ulrich, Kumari, Veena, Zachariah, Elizabeth, Galeas, Adrian, Crawford, Trevor J., Corr, Philip J., ...
Smooth pursuit eye movement (SPEM) and antisaccade deficits are observed in the schizophrenia spectrum and have been used to study the pathophysiology as well as the genetic basis of this condition....
Reliability of smooth pursuit, fixation, and saccadic eye movements. (2003)
Ettinger, Ulrich, Kumari, Veena, Crawford, Trevor J., Davis, Robert E., Sharma, Tonmoy, Corr, Philip J.
The present study investigated the reliability and susceptibility to practice effects of oculomotor tasks. Smooth pursuit, fixation, antisaccade, and prosaccade tasks were administered to 31 healthy...
Relationship between brain structure and saccadic eye movements in healthy humans. (2002)
Ettinger, Ulrich, Kumari, Veena, Chitnis, Xavier A., Corr, Philip J., Sumich, Alex L., Rabe-Hesketh, Sophia, ...
This study used structural magnetic resonance imaging (MRI) to investigate associations between brain structure and saccadic eye movements. Seventeen healthy subjects underwent structural MRI and...

Mapping Morphology of the Corpus Callosum in Schizophrenia (2000)
Narr, Katherine L., Thompson, Paul M., Sharma, Tonmoy, Moussai, Jacob, Cannestra, Andrew F., Toga, Arthur W.
The nature and extent of callosal morphological alterations in schizophrenia remain unresolved. A parametric surface modeling approach using magnetic resonance (MR) images was employed. This provided...

Antipsychotic drug treatment of schizophrenia may be complicated by side effects of widespread dopaminergic antagonism, including exacerbation of negative and cognitive symptoms due to frontal...
