In summary, the present experiments provided evidence that at least some of the presynaptic terminals are silent in response to stimuli, while remaining spontaneously active at the same time.
A putative transmitter acetylcholine depolarized non-specifically the silent cell membrane. It was concluded that the slow depolarization of the silent cell by H+ could not be considered to be the H+-receptor potential and seemed to be dependent upon intact synaptic connections in the slice.

Experiments with three types of keyboards and off-the-shelf smartphones demonstrate scenarios where our system can recover $94\%$ of keystrokes, which to our knowledge, is the first single-device technique that enables acoustic snooping of passwords.

Ambiguous keyboards provide efficient typing with low motor demands.
Soft keyboards, because of their ease of installation and lack of reliance on specific hardware, are a promising solution as an input device for many languages.
The data suggest that acoustic representations activated in silent reading are best characterized as inner speech rather than as abstract phonological codes.
The study indicates both keyboards strengths and weaknesses, and highlights a set of recommendations for developing a more accessible keyboard for blind people.
The SingleTapBraille keyboard was better than the QWERTY keyboard in terms of both speed and accuracy, indicating that SingleTapBraille represents an improvement over existing alternatives in making touchscreen keyboards more accessible for blind users.
Our findings are useful for developing flat keyboards with assistive information through sensory feedback.
We conclude that research on mobile keyboards benefits from observing free typing beyond the lab and discuss ideas for further studies.
