Hand anthropometry and the limits of aperture separation determine the utility of Weber's law in grasping and manual estimation.
Ayala N, Binsted G, Heath M. Ayala N, et al. Exp Brain Res. 2018 Aug;236(8):2439-2446. doi: 10.1007/s00221-018-5311-6. Epub 2018 Jun 19. Exp Brain Res. 2018. PMID: 29923096
Recent work proposed that biomechanical constraints in aperture separation limit the utility of Weber's law in determining whether dissociable visual codes support grasping and manual estimation. We tested this assertion by having participants precision grasp, manually …

Assessing Foveal Structure in Individuals with TYR R402Q and S192Y Hypomorphic Alleles.
Ayala GD, Linderman RE, Valenzuela RK, Woertz EN, Brilliant M, Tarima S, Carroll J. Ayala GD, et al. Ophthalmol Sci. 2021 Nov 17;1(4):100077. doi: 10.1016/j.xops.2021.100077. eCollection 2021 Dec. Ophthalmol Sci. 2021. PMID: 36246950 Free PMC article.
Volumetric scans of the macula were obtained for each participant using OCT, and retinal thickness maps were analyzed using custom software. OCT angiography was used to image the FAZ, which was manually segmented and measured. Linear mixed model analysis was used to assess …

Concurrent adaptation to opposing visuomotor rotations by varying hand and body postures.
Ayala MN, 't Hart BM, Henriques DY. Ayala MN, et al. Exp Brain Res. 2015 Dec;233(12):3433-45. doi: 10.1007/s00221-015-4411-9. Epub 2015 Aug 20. Exp Brain Res. 2015. PMID: 26289481
For the hand posture experiment, we also look at the role of extended training. Participants reached manually to visual targets with their unseen hand represented by a cursor that was rotated either 30 clockwise or counterclockwise, determined randomly on each reach. ...
