Those with anxiety traits were found to have larger peripersonal space.

New findings have allowed scientists to define the limit of the 'peripersonal space' surrounding the face as 20-40cm away.

Peripersonal space: The space within reach of any limb of an individual.

The study of peripersonal space representation in monkey premotor cortex (Science, 1997).

An automobile is automatically absorbed into peripersonal space.

Tactile and visual informations can also b integrated in other peripersonal space regions, such as around the face.

Thus, to be "within arm's length" is to be within one's peripersonal space.

These neurons are especially sensitive to objects in the space immediately surrounding the body, in so-called peripersonal space.

Effects of prismatic adaptation on judgements of spatial extent in peripersonal and extrapersonal space.

The neurons that encode peripersonal space may also provide a neuronal basis for the psychological phenomenon of personal space.

Sounds from far-flung places are projected through instruments to the visitor's peripersonal space through motion detecting sensors.

In the current research, which is published in the Journal of Neuroscience, 15 volunteers aged between 20 and 37 had their peripersonal space assessed.

And when they use a tool, a rake, a joystick or an automobile, their body schema and peripersonal space expand to include it.

This so-called peripersonal space extends to arm's length; people with longer arms have a bigger peripersonal space.

Researchers classified those who reacted more strongly to further away stimuli as having a large 'defensive peripersonal space' (DPPS).

Subsequently, dissociations between left neglect in peripersonal, extrapersonal space, and more recently back space (Viaud-Delmon, Brugger, & Landis, 2007) have been reported.

The peripersonal neurons may also play a central role in the body schema an internally computed model of the body first proposed to exist by Head and Holmes in 1911.

In a second study, again published in Nature, Halligan and Marshall (1991) showed the first convincing evidence in humans for a dissociation between extrapersonal space and peripersonal space.

Patients with neglect for peripersonal space (space within reach), are likely to recover most during the first 10 days after a stroke, but further improvements from 6 months to 1 year post onset are unlikely.

I had this sensation regardless of the size of the airplane I was in, and I now see that it was probably a manifestation of the "peripersonal space" described in the article.

Graziano has made contributions in three areas of neuroscience: how neurons in the primate brain encode peripersonal space, how the motor cortex controls complex movement, and the possible neuronal basis of consciousness.

The space surrounding the body - known by scientists as "peripersonal space" - has previously been thought of as having a gradual boundary, but has been given physical limits by new research into the relationship between anxiety and personal space.

Numerous studies involving peripersonal and extrapersonal neglect have shown that peripersonal space is located dorsally in the parietal lobe whereas extrapersonal space is housed ventrally in the temporal lobe.

He said: "These findings indicate that the defensive peri-personal space has a clear boundary.

This differentiation is significant because the majority of assessment measures test only for neglect within the reaching, or peri-personal, range.

The next range of neglect is "allocentric" neglect, where individuals neglect either their peri-personal or extrapersonal space.

Peri-personal space refers to the space within the patient's normal reach, whereas extrapersonal space refers to the objects/environment beyond the body's current contact or reaching ability.

The behavior of the patient is, in a sense, obligatorily linked to the affordance (using terminology introduced by the American ecological psychologist, J.J. Gibson) presented by objects that are located within the immediate peri-personal environment.
