However, the nature of its contribution is unknown. One possibility is that the somatosensory cortex is transiently engaged during movement. Alternatively, there may be durable learning-related changes which would indicate sensory participation in the encoding of learned movements. These possibilities are dissociated by disrupting the somatosensory cortex following learning, thus targeting learning-related changes which may have occurred. If changes to the somatosensory cortex contribute to retention, which, in effect, means aspects of newly learned movements are encoded there, disruption of this area once learning is complete should lead to an impairment. Participants were trained to make movements while receiving rotated visual feedback. The primary motor cortex (M1) and the primary somatosensory cortex (S1) were targeted for continuous theta-burst stimulation, while stimulation over the occipital cortex served as a control. Retention was assessed using active movement reproduction, or recognition testing, which involved passive movements produced by a robot. Disruption of the somatosensory cortex resulted in impaired motor memory in both tests. Suppression of the motor cortex had no impact on retention as indicated by comparable retention levels in control and motor cortex conditions. The effects were learning specific. When stimulation was applied to S1 following training with unrotated feedback, movement direction, the main dependent variable, was unaltered. Thus, the somatosensory cortex is part of a circuit that contributes to retention, consistent with the idea that aspects of newly learned movements, possibly learning-updated sensory states (new sensory targets) which serve to guide movement, may be encoded there.<\/jats:p>","DOI":"10.1073\/pnas.2316294121","type":"journal-article","created":{"date-parts":[[2024,1,29]],"date-time":"2024-01-29T15:00:21Z","timestamp":1706540421000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":42,"title":["The human somatosensory cortex contributes to the encoding of newly learned movements"],"prefix":"10.1073","volume":"121","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7539-1286","authenticated-orcid":false,"given":"Shahryar","family":"Ebrahimi","sequence":"first","affiliation":[{"name":"Department of Psychology, McGill University, Montreal, QC H3A1G1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7427-6526","authenticated-orcid":false,"given":"David J.","family":"Ostry","sequence":"additional","affiliation":[{"name":"Department of Psychology, McGill University, Montreal, QC H3A1G1, Canada"},{"name":"Yale Child Study Center, Yale School of Medicine, New Haven, CT 06519"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2024,1,29]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1080\/00222895.2012.659232"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tins.2015.12.006"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.7554\/eLife.76639"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cub.2021.01.097"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pbio.3000469"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2017.02.049"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1152\/jn.00231.2023"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1344-15.2015"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1152\/jn.00383.2019"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.2570-07.2007"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.3916-16.2017"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhq192"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1139-06.2006"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(82)90781-8"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(87)90815-8"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.1152\/jn.1980.43.4.1090"},{"key":"e_1_3_4_17_2","first-page":"4244","article-title":"Representations of fine digit movements in posterior and anterior parietal cortex revealed using long-train intracortical microstimulation in macaque monkeys","volume":"28","author":"Baldwin M.
