Abstract

The tactile consequences of self-initiated movements are thought to be predicted by a forward model (FM), yet the precise neural implementation of these predictions remains unclear. In nonmotor contexts, expectations are thought to activate sensory neurons tuned toward the expected stimulus. This acts as a predictive template against which afferent sensory input is compared. It is unclear whether FM predictions have a similar neural instantiation. Here we employed time-resolved multivariate decoding on human electroencephalography during self-generated movements to examine the content of predictive neural activity. Human participants (males and females) performed index finger movements which were predictably paired with a vibration to either the index or ring finger of the opposite, passive hand. On some trials the tactile stimulus was unexpectedly omitted. Results revealed above-chance finger decoding in the premovement period supporting a predictive representation of expected stimulation location. As the movement approached, this predictive activity became similar to late-stage processing of a physical tactile stimulus. On omission trials, we found that despite the absence of afferent input, finger location could be decoded ∼120 ms after expected stimulus onset. This shows a stimulus-specific omission response. Together these findings indicate that self-generated movement preactivates neurons tuned toward expected tactile consequences.

Code

No file of the authors' code could be read here: it is described below, and read at its source.

The paper's code and data availability statement is in the Data section.

Tracing map

Proposed by the machine: these links were found in the paper and verified at the source, without human review. The map will receive a Zenodo DOI once one of the paper's authors has validated it with their ORCID.

What the map holds:

• 1 repository of the authors' code, each at its verified commit, with its license and how the link was found in the paper;
• 0 scripts, each with its path and the digest of its content;
• no match between paragraphs and code yet;
• neither the text of the paper nor the code itself.

Its JSON (tracing-map.json) is deposited on Zenodo with its DOI once the map is validated.

Data

No dataset and no data link were found in the paper.

Data Availability

All experiment scripts, preprocessed data, and analysis code will be made available on the Open Science Framework (https://osf.io/yw8sa/).
