Distinct causal influences of parietal versus frontal areas on human visual cortex: evidence from concurrent TMS-fMRI [PDF]

open access: yes, 2010
It has often been proposed that regions of the human parietal and/or frontal lobe may modulate activity in visual cortex, for example, during selective attention or saccade preparation.

Post stroke othello syndrome: A rare clinical presentation of right parietal lobe infarct

open access: yesTelangana Journal of Psychiatry, 2015
Background: Delusional jealousy also known as Othello syndrome has been described as a part of various neurological and psychiatric conditions. Case Description: Here, we present a case of a 65 year old male patient who developed a delusion of infidelity

The continuous Wagon wheel illusion and the 'when' pathway of the right parietal lobe: a repetitive transcranial magnetic stimulation study. [PDF]

open access: yesPLoS ONE, 2008
A continuous periodic motion stimulus can sometimes be perceived moving in the wrong direction. These illusory reversals have been taken as evidence that part of the motion perception system samples its inputs as a series of discrete snapshots -although ...

Assembly and use of new task rules in fronto-parietal cortex [PDF]

open access: yes, 2011
Severe capacity limits, closely associated with fluid intelligence, arise in learning and use of new task rules. We used fMRI to investigate these limits in a series of multirule tasks involving different stimuli, rules, and response keys.

Effects of rTMS conditioning over the fronto-parietal network on motor versus visual attention [PDF]

open access: yes, 2007
Many studies have shown that visuospatial orienting attention depends on a network of frontal and parietal areas in the right hemisphere. Rushworth et al. [Rushworth, M. F., Krams, M., & Passingham, R. E. The attentional role of the left parietal cortex:

Neural correlates of attentional capture in visual search [PDF]

open access: yes, 2004
Much behavioral research has shown that the presence of a unique singleton distractor during a task of visual search will typically capture attention and thus disrupt search.

Fronto-parietal cortex activation during walking in patients with Parkinson's disease adopting different postural strategies

open access: yesFrontiers in Neurology, 2022
BackgroundCortical activation patterns in patients with Parkinson's disease (PD) may be influenced by postural strategies, but the underlying neural mechanisms remain unclear.

Studying the Role of Human Parietal Cortex in Visuospatial Attention with Concurrent TMS-fMRI [PDF]

open access: yes, 2010
Combining transcranial magnetic stimulation (TMS) with concurrent functional magnetic resonance imaging (fMRI) allows study of how local brain stimulation may causally affect activity in remote brain regions.
