Visual neglect after right posterior cerebral artery infarction (2006)
Bird, C.M., Malhotra, P., Parton, A., Coulthard, E., Rushworth, M.F., Husain, M.
OBJECTIVES: To investigate the characteristics and neuroanatomical correlates of visual neglect after right-sided posterior cerebral artery (PCA) infarction. METHODS: 15 patients with acute PCA...
Hemispatial neglect, balance and eye-movement control (2006)
Malhotra, P., Coulthard, E., Husain, M.
Purpose of review: Disorders of spatial awareness and balance following stroke are common but often under-diagnosed. They lead to poor outcome and frequently coexist. Here we focus on recent progress...
Noradrenergic modulation of space exploration in visual neglect (2006)
Malhotra, P., Parton, A., Greenwood, R., Husain, M.
Visual neglect after stroke is often associated with a failure to explore contralesional space. Here, we show that guanfacine, a noradrenergic agonist that modulates dorsolateral prefrontal cortex,...
Space re-exploration in hemispatial neglect (2006)
Parton, A., Malhotra, P., Nachev, P., Ames, D., Ball, J., Chataway, J., ...
Exploration of the space around us is a fundamental part of human behaviour. When it breaks down there is an important opportunity to understand its underlying mechanisms. Here we show that many...
Spatial working memory capacity in unilateral neglect (2005)
Malhotra, P., Jager, R., Parton, A., Greenwood, R., Playford, D.T., Brown, M.M., ...
It has been proposed recently that a deficit in keeping track of spatial locations may contribute to the severity of unilateral neglect in some right hemisphere stroke patients. However, performance...
Priming of colour and position during visual search in unilateral spatial neglect (2005)
Kristjansson, A., Vuilleumier, P., Husain, M., Malhotra, P., Driver, J.
We examined priming of visual search by repeated target location or color in two patients with left visual neglect and extinction, following strokes centered on the right inferior parietal lobe. Both...
Attention modulates the visual field in healthy observers and parietal patients (2004)
Russell, C., Malhotra, P., Husain, M.
Recent attention research suggests that factors other than low-level sensory processes modulate perception across the visual field, with right parieto-temporal cortex playing a critical role in...
Impaired spatial working memory: One component of the visual neglect syndrome? (2004)
Malhotra, P., Mannan, S., Driver, J., Husain, M.
Both impaired spatial working memory (SWM) and unilateral neglect may follow damage to the right parietal lobe. We propose that impaired SWM can exacerbate visual neglect, due to failures in...
Impaired spatial working memory: One component of the visual neglect syndrome? (2004)
Malhotra, P., Mannan, S., Driver, J., Husain, M.
Both impaired spatial working memory (SWM) and unilateral neglect may follow damage to the right parietal lobe. We propose that impaired SWM can exacerbate visual neglect, due to failures in...
Reply to: Using SPM normalization for lesion analysis in spatial neglect (2004)
Mort, D.J., Malhotra, P., Mannan, S.K., Rorden, C., Pambakian, A., Kennard, C., ...
Parton, A., Malhotra, P., Husain, M.
The syndrome of hemispatial neglect is characterised by reduced awareness of stimuli on one side of space, even though there may be no sensory loss. Although it is extremely common, it has proven to...
The anatomy of visual neglect (2003)
Mort, D.J., Malhotra, P., Mannan, S.K., Rorden, C., Pambakian, A., Kennard, C., ...
The brain regions that are critically associated with visual neglect have become intensely disputed. In particular, one study of middle cerebral artery (MCA) stroke patients has claimed that the key...
Prism adaptation can improve contralesional tactile perception in neglect (2003)
McNeil, J., Malhotra, P., Greenwood, R., Hussain, M., Driver, J.
The authors show that prismatic adaptation can reduce tactile inattention in stroke patients with unilateral neglect. Four patients with visuospatial neglect and tactile extinction underwent...
Prism adaptation can improve contralesional tactile perception in neglect (2003)
Maravita, A., McNeil, J., Malhotra, P., Greenwood, R., Husain, M., Driver, J.
he authors show that prismatic adaptation can reduce tactile inattention in stroke patients with unilateral neglect. Four patients with visuospatial neglect and tactile extinction underwent 10-minute...

Effect of single-base substitutions in the central domain of virus-associated RNA I on its function.
Rahman, A, Malhotra, P, Dhar, R, Kewalramani, T, Thimmapaya, B
Adenoviruses use virus-associated RNA I (VAI RNA) to counteract the cellular antiviral response mediated by the interferon-induced, double-stranded-RNA-activated protein kinase PKR. VAI RNA is a...
Ghadge, G D, Malhotra, P, Furtado, M R, Dhar, R, Thimmapaya, B
Adenoviruses use the virus-encoded virus-associated RNA (VAI RNA) as a defense against cellular antiviral response by blocking the activation of the interferon-induced, double-stranded RNA-activated...
Swaminathan, S, Malhotra, P, Manohar, C F, Dhar, R, Thimmapaya, B
The role of TATA elements in the expression of a mammalian promoter was investigated in the fission yeast Schizosaccharomyces pombe, by studying the human adenovirus E2-early promoter. This is a...
