The present invention introduces an approach to neural tissue engineering by developing vascularized neurospheres (VNSs) through novel methods, systems, and kits. These VNSs are generated using a unique blend of neural, vascular, and supportive cells, cultured in specialized hydrogel-containing media. The VNSs feature an integrated vascular network, serving as a physiologically relevant in vitro model. The invention also offers a grafting technique for therapeutic applications in neural disorders and injuries, as well as facilitating brain-computer interfacing. Beyond therapeutics, the VNSs have broad applications in drug development, synthetic biology, disease modeling, and more. The invention also includes kits for VNS generation and methods for interfacing VNSs with probes for applications of brain-computer interfacing. Overall, this patent represents a significant leap in the field, bridging the gap between in vitro and in vivo systems and opening new avenues in research, therapeutics, and bioengineering.

A system and method relating to a brain-computer interface in which a visual stimulus overlaying one or more objects is provided, the visual stimulus having a characteristic modulation. The brain computer interface measures neural response to objects viewed by a user. The neural response to the visual stimulus is correlated to the modulation. The method allows the interface to discriminate between merely viewing of a display object and deliberate selection of that display object (for example, as a trigger to a further action).
