It is uncertain whether and to what extent retinal reorganization may limit the perception of multiple phosphenes by blind prosthesis recipients. If distinct phosphenes can be perceived, these results suggest that a 3 x 3-mm2 prosthesis with 16 x 16 electrodes should allow paragraph reading. The effects of stabilizing the dot grid on the retina must be investigated further.

In this article David Barnett investigates the ways in which plays can be considered 'postdramatic'. Opening with an exploration of this new paradigm, he then seeks to examine two plays, Attempts on her Life by Martin Crimp and 4:48 Psychosis by Sarah Kane, in a bid to understand how their texts frustrate representation and the structuring of time, and concludes by considering how the restrictions imposed upon the postdramatic performance differ from the interpretive freedom of text in representational, dramatic theatre. David Barnett is senior lecturer and Head of Drama at the University of Sussex. He has published monographs on Heiner Müller (1998) and Rainer Werner Fassbinder (2005), the latter as Research Fellow of the Humboldt Foundation, Germany. He has also published articles on contemporary German, English-language, political, and postdramatic theatre.https://www.cambridge.org/core/terms. https://doi

Michael Frayn's play about quantum mechanics, memory and history, Copenhagen, has taken a lot of criticism for ‘misrepresenting’ its historical characters, primarily Werner Heisenberg. This essay analyses the dramaturgy of the play and argues for a postdramatic reading in which questions of representation are dissolved by formal strategies that ally themselves with the thematics of the work. The text is viewed as a hybrid, somewhere between the dramatic and the postdramatic, set, as it is, in a fictional afterlife where conventional human categories no longer function. The postdramatic theatre, in refusing to interpret text, becomes a viable mode for performance in that the indeterminacy of meaning on stage equates with the uncertainty principle that lies at the scientific and moral heart of Copenhagen.
