After the first scanning session, the experimental group was given auditory discrimination training across six sessions spread over two weeks (for training details, see Auditory Discrimination Training and Tasks).
An MCS patient was instructed to imagine playing tennis when she heard the word "tennis," or to imagine walking through her house when she heard the word "house"; she was then positioned in the scanner and given auditory prompts.
All synthesized videos were to be synchronized to the given auditory speech as a prerequisite.
In a trailer on the site, twins were given auditory tests that involved piping a different sound into each ear simultaneously.
Given the relative importance of its contribution, recovering the pitch of a signal is integral for constructing a holistic percept for a given auditory stimulus and ultimately arriving at the recognition of an auditory object.
In the same manner, a given auditory area might have several orthogonal receptive field characteristics (for example preference for species-specific vocalizations or communication calls [43], [45]); one of them appears to be, as our findings show, a cochleotopic topographical organization.
We assumed that the state of vigilance ascertained by electroencephalography (EEG) during the perception of a given auditory rhythm would influence its reproduction.
The computer gave auditory feedback with a high-pitched tone when a correct button was pressed and a lower pitched tone for an incorrect selection.
After the training, we tested the network with a view to revealing the presence and activation properties of HNCs (cell assemblies) that we predicted would emerge for the given auditory-motor pattern pairs.
Recordings started, for each penetration, 600 µm below the brain surface, at a site that gave no auditory response, and continued until 4000 µm below the brain surface, where auditory responses were no longer detectable.
