it could not be extended in duration by flickering the cue, nor did it require a local sensory transient o trigger its onset. Neither the variation in retinal eccentricity nor changing the paradigm to a vernier acuity task altered the basic pattern of results. Our findings indicate the existence of a

Mutations in genes affecting endocrine signaling, stress responses, metabolism, and telomeres can all increase the life spans of model organisms. These mutations have revealed evolutionarily conserved pathways for aging, some of which appear to extend life span in response to sensory cues, caloric

and hallucinatory phenomena, to position codes for mo~or control, to pattern discrimination, to influences of novel events on storage of redundant relevant cues, and to the construction of a sensory-drive heterarchy are mentioned, along with possible anatomical substrates in neocortex, hypothalamus, and hippocampus

The left parietal lobe has been proposed as a major language area. However, parietal cortical function is more usually considered in terms of the control of actions, contributing both to attention and cross-modal integration of external and reafferent sensory cues. We used positron emission

■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories

The vestibular sensory apparatus and associated vestibular nuclei are generally thought to encode head-in-space motion. Angular head-in-space velocity is detected by vestibular hair cells that are located within the semicircular canals of the inner ear. In turn, the afferent fibers

•Acoustic packaging makes use of the synchrony between the visual and audio modality in order to detect temporal structure in actions that are demonstrated to children and robots [1]. •Support for action and language learning in robots •Acoustic packages form early units for further learning processes. • Feedback generation during tutoring. Figure: A test subject showing how to stack cups to an infant. System Overview •Modular and decoupled approach •Modules communicate through a central memory: the Active Memory [2]. • The Active Memory notifies components about event types they have subscribed to. •All modules are able to incrementally update their hypotheses based on the events they receive.

When a part of the body moves, the sensation evoked by a probe stimulus to that body part is attenuated. Two mechanisms have been proposed to explain this robust and general effect. First, feedforward motor signals may modulate activity evoked by incoming sensory signals. Second, reafferent

Elasmobranch fishes have an electroreceptive system which they use for prey detection and orientation. Sensory inputs in this system are corrupted by a form of reafference generated by the animal's own ventilation. However, we show here that in the carpet shark, Cephaloscylium Isabella

Abstract Nervous systems distinguish between self-and other-generated movements by monitoring discrepancies between planned and performed actions. To do so, corollary discharges are conveyed to sensory areas and gate expected reafference. Such gating is observed in neonatal rats during wake
