D’Amour et al. 2015. “Bodily illusions disrupt tactile sensations”

Abstract. To accurately interpret tactile information, the brain needs to have an accurate representation of the body to which to refer the sensations. Despite this, body representation has only recently been incorporated into the study of tactile perception. Here, we investigate whether distortions of body representation affect tactile sensations. We perceptually altered the length of the arm and the width of […]

Dokka et al. 2010. “Self versus environment motion in postural control”

Abstract. To stabilize our position in space we use visual information as well as non-visual physical motion cues. However, visual cues can be ambiguous: visually perceived motion may be caused by self-movement, movement of the environment, or both. The nervous system must combine the ambiguous visual cues with noisy physical motion cues to resolve this ambiguity and control our body posture. […]

Jörntell et al. 2014. “Segregation of tactile input features in neurons of the cuneate nucleus”

Abstract. Our tactile perception of external objects depends on skin-object interactions. The mechanics of contact dictates the existence of fundamental spatiotemporal input features—contact initiation and cessation, slip, and rolling contact—that originate from the fact that solid objects do not interpenetrate. However, it is unknown whether these features are represented within the brain. We used a novel haptic interface to deliver […]

Adrian. 1931. “Croonian lecture: the messages in sensory nerve fibers and their interpretation”

Abstract. The nervous apparatus which intervenes between stimulus and sensation has been the subject of more than one Croonian lecture. It may claim to be a suitable topic for a discourse on the “Causes  and reasons of the phenomena of local motion,” but it is a dangerous topic as well, since it forces us to consider the mind as well as […]

Shea et al. 2014. “Supra-personal cognitive control and metacognition”

Abstract. The human mind is extraordinary in its ability not merely to respond to events as they unfold but also to adapt its own operation in pursuit of its agenda. This ‘cognitive control’ can be achieved through simple interactions among sensorimotor processes, and through interactions in which one sensorimotor process represents a property of another in an implicit, unconscious way. So […]

Vetter et al. 2014. “Decoding Sound and Imagery Content in Early Visual Cortex”

Abstract. Human early visual cortex was traditionally thought to process simple visual features such as orientation, contrast, and spatial frequency via feedforward input from the lateral geniculate nucleus. However, the role of nonretinal influence on early visual cortex is so far insufficiently investigated despite much evidence that feedback connections greatly outnumber feedforward connections. Here, we explored in five fMRI experiments how […]
