We describe mirror manifolds in dimensions different from the familiar case of complex threefolds. We emphasize the simplifying features of dimension three and supply more robust methods that do not rely on such special characteristics and hence naturally generalize to other dimensions. The moduli spaces for Calabi–Yau d-folds are somewhat different from the “special Kähler manifolds” which had...

The discovery of mirror neurons has suggested a potential neural basis for simulation and common coding theories of action perception, theories which propose that we understand other people's actions because perceiving their actions activates some of our neurons in much the same way as when we perform the actions. We propose testing this model directly in humans with functional magnetic resonan...

This paper describes a model for Computer Support Reflective Learning (CSRL) as a conceptual framework to support the design, application and evaluation for tools supporting reflection as a learning mechanism at work. The CSRL model has been derived from theory and inspired by empirical work done in the MIRROR project. It contains necessary steps of reflection, which form a reflection cycle and...

effects of oral administration of testosterone and fluoxetine exposure on aggressive behavior of the fighting fish, betta splendens , were investigated. testosterone diluted in ethanol and sprayed on pre-weighted pellet to achieve concentrations of 0, 1, 2 and 4 mg/kg of hormone in food. two main behaviors were recorded: the time in front of mirror and duration of the gill flaring using a mirro...

background and objective: cerebro-vascular accident (cva) is considered to be one of the main causes of acquired motor disability in adults. different motor rehabilitation programs are being designed in order to improve motor difficulties of patients with cva. in the current study we aimed to assess the effect of task-based mirror therapy on upper limb functions and activities of daily living i...

Vertical External Cavity Surface Emitting Lasers (VECSELs) are a type of laser that have been found to be useful in situations requiring high output power and pulses of short duration. The typical VECSEL is composed of (at least) two mirrors: the active or gain mirror where the light is amplified and reflected and an outcoupling mirror where some laser light is allowed to exit the laser. When o...

We first give a complete, albeit brief, review of the discovery of mirror symmetry in N = 2 string/conformal field theory. In particular, we describe the naturality arguments which led to the initial mirror symmetry conjectures and the subsequent work which established the existence of mirror symmetry through direct construction. We then review a number of striking consequences of mirror symmet...

Since their discovery, mirror neurons--units in the macaque brain that discharge both during action observation and execution--have attracted considerable interest. Whether mirror neurons are an innate endowment or acquire their sensorimotor matching properties ontogenetically has been the subject of intense debate. It is widely believed that these units are an innate trait; that we are born wi...

There is strong evidence that neonates imitate previously unseen behaviours. These behaviours are predominantly used in social interactions, demonstrating neonates' ability and motivation to engage with others. Research on neonatal imitation can provide a wealth of information about the early mirror neuron system (MNS), namely its functional characteristics, its plasticity from birth and its re...

In this article we provide a unifying neural hypothesis on how individuals understand the actions and emotions of others. Our main claim is that the fundamental mechanism at the basis of the experiential understanding of others' actions is the activation of the mirror neuron system. A similar mechanism, but involving the activation of viscero-motor centers, underlies the experiential understand...
