Although there is a vast clinical literature on phantom limbs, there have been no experimental studies on the effects of visual input on phantom sensations. We introduce an inexpensive new device--a 'virtual reality box'--to resurrect the phantom visually to study inter-sensory effects. A mirror is placed vertically on the table so that the mirror reflection of the patient's intact had is 'supe...

This paper presents a compact analog neuron cell incorporating an array of charge-coupled synapses connected via a common output terminal. The novel silicon synapse is based on a two stage charge-coupled device where the weighting functionality can be integrated into the first stage. A presynaptic spike to the second gate allows the charge under the first gate to drift onto the floating diffusi...

The mirror neuron hypothesis of autism is highly controversial, in part because there are conflicting reports as to whether putative indices of mirror system activity are actually deficient in autism spectrum disorder (ASD). Recent evidence suggests that a typical putative mirror system response may be seen in people with an ASD when there is a degree of social relevance to the visual stimuli u...

Humans readily perceive ownership of a limb even when it is artificially induced as in the case of using a mirror reflection. However, mirror reflections are very constrained perceptions which do not allow transformations and varied contexts as often occurs in real life. The extent to which perceived limb ownership occurs with video-mediated manipulations is not known, particularly given the pe...

Cerebral damage which renders the preferred arm useless may lead patients to use their non-preferred arm for everyday tasks including writing. In these circumstances, mirror writing and other mirror movements may occur. The present study on 10 formerly right-handed patients was carried out to determine whether similar phenomena occurred when serious damage to the right arm itself had occurred, ...

Background: Stroke is one of the major causes of disability. Therefore, it is important to introduce and develop new treatment approaches in order to improve and enhance post stroke recovery process for medical, social and economical purposes. Aim: To determine the effect of mirror therapy on motor ability of patients with stroke. Methods: This Randomized Controlled Trial was conducted on 38 pa...

The mirror puzzle related to the perception of mirror images as left-right reversed can be more fully understood by considering an extended problem that includes also the perception of mirror images that are not left-right reversed. The purpose of the present study is to clarify the physical aspect of this extended problem logically and parsimoniously. Separate use of the intrinsic frame of ref...

This paper proposes and evaluates the use of a mirror for improving the scanning process when using laser-stripe acquisition devices. We propose to exploit mirrors for two different purposes: automatizing the 3D acquisition process and allowing the scanning of hard-to-reach parts. The combined use of a flat mirror and a rotary table allows to scan, in a completely automatic and unattended manne...
