Patients with lesions to the intraparietal cortex show greater proprioceptive realignment after prism adaptation: Evidence from open-loop pointing and manual straight ahead.
Bultitude JH, Hollifield M, Rafal RD. Bultitude JH, et al. Neuropsychologia. 2021 Jul 30;158:107913. doi: 10.1016/j.neuropsychologia.2021.107913. Epub 2021 Jun 15. Neuropsychologia. 2021. PMID: 34139246
Common ways to measure adaptation after-effect are to ask a person to point straight ahead with their eyes closed ("manual straight ahead", MSA), or to a seen target using their unseen hand ("open-loop pointing", OLP). ...After-effects were measured with OLP …

A systematic review on functional electrical stimulation based rehabilitation systems for upper limb post-stroke recovery.
Khan MA, Fares H, Ghayvat H, Brunner IC, Puthusserypady S, Razavi B, Lansberg M, Poon A, Meador KJ. Khan MA, et al. Front Neurol. 2023 Dec 8;14:1272992. doi: 10.3389/fneur.2023.1272992. eCollection 2023. Front Neurol. 2023. PMID: 38145118 Free PMC article.
More specifically, this paper aims to review different types of FES systems, their feasibility testing, or randomized control trials (RCT) studies. METHODS: The FES systems classification is based on the involvement of patient feedback within the FES control, which …

GoCARB in the Context of an Artificial Pancreas.
Agianniotis A, Anthimopoulos M, Daskalaki E, Drapela A, Stettler C, Diem P, Mougiakakou S. Agianniotis A, et al. J Diabetes Sci Technol. 2015 May;9(3):549-55. doi: 10.1177/1932296815583333. Epub 2015 Apr 21. J Diabetes Sci Technol. 2015. PMID: 25904142 Free PMC article.
When the GoCARB is used, the corresponding percentages are 99.7% and 99.8%. In case of open loop, the time spent in severe hypoglycemic events (<50 mg/dl) is 33.6% without the GoCARB and is reduced to 0.0% when the GoCARB is used. In case of closed loop, the corr …

The perceptual dynamics of the contrast induced speed bias.
Patricio Décima A, Fernando Barraza J, López-Moliner J. Patricio Décima A, et al. Vision Res. 2022 Feb;191:107966. doi: 10.1016/j.visres.2021.107966. Epub 2021 Nov 19. Vision Res. 2022. PMID: 34808549 Free article.
We further tested these predictions using a novel experimental paradigm that allows us to measure the dynamic perceptual difference between stimuli through a series of manual pursuit open loop tasks. Results show good agreement with our model's predictions. . …

Semmlow JL, Yaramothu C, Alvarez TL. Semmlow JL, et al. J Eye Mov Res. 2019 Oct 3;12(4):10.16910/jemr.12.4.11. doi: 10.16910/jemr.12.4.11. Epub 2019 Dec 4. J Eye Mov Res. 2019. PMID: 32318253 Free PMC article.
The initial component has been well-studied and is thought to be controlled by an open-loop mechanism. Less is known about the slow, or fusion sustaining component except that it must be feedback controlled to achieve the positional precision of sustained fusion. Gi …
