Reaching with the sixth sense: Vestibular contributions to voluntary motor control in the human right parietal cortex

Reichenbach, Alexandra ; Bresciani, Jean-Pierre ; Bülthoff, Heinrich H. ; Thielscher, Axel

In: NeuroImage, 2016, vol. 124, Part A, p. 869–875

The vestibular system constitutes the silent sixth sense: It automatically triggers a variety of vital reflexes to maintain postural and visual stability. Beyond their role in reflexive behavior, vestibular afferents contribute to several perceptual and cognitive functions and also support voluntary control of movements by complementing the other senses to accomplish the movement goal....

A key region in the human parietal cortex for processing proprioceptive hand feedback during reaching movements

Reichenbach, Alexandra ; Thielscher, Axel ; Peer, Angelika ; Bülthoff, Heinrich H. ; Bresciani, Jean-Pierre

In: NeuroImage, 2014, vol. 84, p. 615–625

Seemingly effortless, we adjust our movements to continuously changing environments. After initiation of a goal-directed movement, the motor command is under constant control of sensory feedback loops. The main sensory signals contributing to movement control are vision and proprioception. Recent neuroimaging studies have focused mainly on identifying the parts of the posterior parietal cortex...
