Right Temporoparietal Cortex Activation during Visuo-proprioceptive Conflict

Right temporoparietal cortex activation during visuo-proprioceptive conflict.

The conflict between vision and proprioception has been proposed to explain why healthy subjects perform worse than proprioceptively deafferented patients in conditions with optical displacement, e.g. novel mirror drawing. It is not known which brain processes depend upon the successful integration of visual and proprioceptive information and are therefore impaired when these modalities disagre...

Hypofunction of right temporoparietal cortex during emotional arousal in depression.

CONTEXT Neuropsychological models of depression highlight temporoparietal hypofunction associated with low emotional arousal in major depressive disorder (MDD). These models were derived from indirect measures such as neuropsychological tests and electroencephalography alpha band power. OBJECTIVE To determine if high-arousing stimuli directly modulated activity in attention and arousal-relate...

Visuo-proprioceptive interactions during adaptation of the human reach.

We examined whether visual and proprioceptive estimates of transient (midreach) target capture errors contribute to motor adaptation according to the probabilistic rules of information integration used for perception. Healthy adult humans grasped and moved a robotic handle between targets in the horizontal plane while the robot generated springlike loads that varied unpredictably from trial to ...

Running Head : Intersensory conflict and the rTPJ The role of the right temporoparietal junction in intersensory conflict : Detection or resolution ?

Right temporoparietal junction and attentional reorienting.

The interaction between goal-directed and stimulus-driven attentional control allows humans to rapidly reorient to relevant objects outside the focus of attention--a phenomenon termed contingent reorienting. Neuroimaging studies have observed activation of the ventral and dorsal attentional networks, but specific involvement of each network remains unclear. The present study aimed to determine ...
