Full-body illusions and minimal phenomenal selfhood

Olaf Blanke

We highlight the latest research on body perception and self-consciousness, but argue that despite these achievements, central aspects have remained unexplored, namely, global aspects of bodily self-consciousness. Researchers investigated central represent ...

The mental time line: an analogue of the mental number line in the mapping of life events

Olaf Blanke

A crucial aspect of the human mind is the ability to project the self along the time line to past and future. It has been argued that such self-projection is essential to re-experience past experiences and predict future events. In-depth analysis of a nove ...

Non-retinotopic feature integration decreases response-locked brain activity as revealed by electrical neuroimaging

Michael Herzog, Olaf Blanke, Thomas Otto, Manuel Mercier, Gijs Plomp

When presented with dynamic scenes, the brain integrates visual elements across space and time. Such non-retinotopic processing has been intensively studied from a psychophysical point of view, but little is known about the underlying neural processes. Her ...

Subjective mental time: the functional architecture of projecting the self to past and future

Olaf Blanke, Silvio Ionta

Human experience takes place in the line of mental time (MT) created through 'self-projection' of oneself to different time-points in the past or future. Here we manipulated self-projection in MT not only with respect to one's life events but also with res ...

A putative implication for fronto-parietal connectivity in out-of-body experiences

Olaf Blanke, Christine Mohr

Self-processing has been related to the prefrontal cortex (PFC) and the temporo-parietal junction (TPJ) as well as to their connectivity. So far, out-of-body experiences (OBEs), impressive transient deviations of intact bodily self-integration, could be as ...

Gravity and observer's body orientation influence the visual perception of human body postures

Christelle Bachofner, Olaf Blanke, Manuel Mercier, Christophe Lopez

Since human behavior and perception have evolved within the Earth's gravitational field, humans possess an internal model of gravity. Although gravity is known to influence the visual perception of moving objects, the evidence is less clear concerning the ...

The timing of temporoparietal and frontal activations during mental own body transformations from different visuospatial perspectives

Olaf Blanke, Bigna Lenggenhager

The perspective from where the world is perceived is an important aspect of the bodily self and may break down in neurological conditions such as out-of-body experiences (OBEs). These striking disturbances are characterized by disembodiment, an external pe ...

Seeing the phantom: a functional magnetic resonance imaging study of a supernumerary phantom limb

François Lazeyras, Olaf Blanke, Sebastian Dieguez Falcon

OBJECTIVE: Supernumerary phantom limb (SPL) is a rare neurological manifestation where patients with a severe stroke-induced sensorimotor deficit experience the illusory presence of an extra limb that duplicates a real one. The illusion is most often exper ...

Preliminary evidence for a fronto-parietal dysfunction in able-bodied participants with a desire for limb amputation

Olaf Blanke, Peter Andreas Brugger

BACKGROUND: Reports of able-bodied participants with the persisting desire for limb amputation raise legal and ethical questions that are partly due to insufficient empirical knowledge about the condition. Here, we searched for potential neurological mecha ...

Differential influence of hands posture on mental rotation of hands and feet in left and right handers

Olaf Blanke, Silvio Ionta

The representation of the body in the brain is continuously updated with regard to peripheral factors such as position or movement of body parts. In the present study, we investigated the effects of arm posture on the mental rotation of hands and feet. Six ...

Three sequential brain activations encode mental transformations of upright and inverted human bodies: a high resolution evoked potential study

Ravi Tej Sai Giridhar Tadi, Olaf Blanke

Human bodies provide a particularly rich source of visual information. Whereas most previous studies have focused on the neural mechanisms during the perception and recognition of human bodies, the aim of the present study was to investigate the time cours ...

Motion direction tuning in human visual cortex

Olaf Blanke, Manuel Mercier

A number of electrophysiological studies have been conducted in recent years in order to clarify the dynamics of visual motion processing in the human brain. Using a variety of event-related potential (ERP) measures, several parameters such as onset, offse ...

Brain technologies raise unprecedented ethical challenges

Embodiment, ego-space and action

Dorsal-ventral integration in the recognition of motion-defined unfamiliar faces

Olaf Blanke

The primate visual system is organized into two parallel anatomical pathways, both originating in early visual areas but terminating in posterior parietal or inferior temporal regions. Classically, these two pathways have been thought to subserve spatial v ...

Common Mechanisms For Locating The Self In Space And Time: Evidence From Intracranially Recorded Evoked Potentials

The vestibular component in out-of-body experiences: a computational approach

Olaf Blanke

Neurological evidence suggests that disturbed vestibular processing may play a key role in triggering out-of-body experiences (OBEs). Little is known about the brain mechanisms during such pathological conditions, despite recent experimental evidence that ...

Out-of-body experiences: false climbs in a supine position?

Olaf Blanke

Out-of-body experiences (OBEs) are illusions, where people experience themselves as being located outside their physical body and often flying or floating at an elevated location. Here, we propose that the flying and floating in OBEs can be explained as th ...

Mental perspective transformations: ERP analyses and single trial EEG classification

Influence of galvanic vestibular stimulation on egocentric and object-based mental transformations

Olaf Blanke, Bigna Lenggenhager, Christophe Lopez

The vestibular system analyses angular and linear accelerations of the head that are important information for perceiving the location of one's own body in space. Vestibular stimulation and in particular galvanic vestibular stimulation (GVS) that allow a s ...
