Forward Prediction in the Posterior Parietal Cortex and Dynamic Brain-Machine Interface
While remarkable progress has been made in brain-machine interfaces (BMIs) over the past two decades, it is still difficult to utilize neural signals to drive artificial actuators to produce predictive movements in response to dynamic stimuli. In contrast to naturalistic limb movements largely based on forward planning, brain-controlled neuroprosthetics mainly rely on feedback without prior tra...
متن کاملTHE EFFECT OF POSTERIOR CEREBRAL PULMONARY DIRECT ELECTRICAL STIMULATION (TDCS) ON IMPROVING SPATIAL, VISUAL, AND VERBAL PERCEPTUAL ABILITIES
Background & Aims: Direct electrical stimulation of the brain is a therapeutic technique that can be effective in improving visual, verbal, and spatial perception. The present study investigated the effect of direct electrical stimulation (tDCS) of the posterior parietal cortex on improving spatial, visual, and verbal perceptual abilities. Materials & Methods: In this quasi-experimental study,...
متن کاملAltered Error Processing following Vascular Thalamic Damage: Evidence from an Antisaccade Task
Event-related potentials (ERP) research has identified a negative deflection within about 100 to 150 ms after an erroneous response--the error-related negativity (ERN)--as a correlate of awareness-independent error processing. The short latency suggests an internal error monitoring system acting rapidly based on central information such as an efference copy signal. Studies on monkeys and humans...

Abstract The aim of the present study was to investigate the relationship between perfectionism, as a personality trait, and the brain structure. A total of 49 volunteers (23 women, 26 men) participated in this study by filling a Farsi version of the Positive and Negative Perfectionism Scale (FPANPS) and attending an MRI session. Voxel-based morphometry (VBM) method was used to analyze the MRI...
متن کاملDifferential Cortical Oscillatory Patterns in Amputees with and Without Phantom Limb Pain
Objective: Phantom limb pain (PLP) as neuropathic pain affects the life of amputees. It is believed an efficient PLP treatment should consider the underlying neurological mechanisms. Hereby, we investigated brain activity in PLP’s and relations to the psychological and cognitive dimension of chronic pain. We investigate differences in resting brain activities between amputees with and without p...
