Constructive perception of self-motionJan E Holly
Department of Mathematics, Colby College, Waterville, ME, USA
J Vestib Res 18:249-66. 2008..Such analysis will lead to perceptual rules analogous to those recognized in visual perception...
Sensory conflict compared in microgravity, artificial gravity, motion sickness, and vestibular disordersJan E Holly
Department of Mathematics and Statistics, Colby College, Waterville, ME 04901, USA
J Vestib Res 22:81-94. 2012..3 Hz for OVAR, solving a mystery of this experimentally observed discrepancy. Finally, we determined that certain sensory conflict perceptions reported by vestibular patients could be explained via mathematical simulation...
Differences between perception and eye movements during complex motionsJan E Holly
Department of Mathematics and Statistics, Colby College, Waterville, ME, USA
J Vestib Res 21:193-208. 2011..In addition, while eye movements are consistent with linear filtering processes, perceived motion has dynamics that cannot be explained by basic differences in time constants, filtering, or standard GIF-resolution processes...
Phase-linking and the perceived motion during off-vertical axis rotationJan E Holly
Department of Mathematics, Colby College, 5845 Mayflower Hill, Waterville, ME, 04901, USA
Biol Cybern 102:9-29. 2010..In addition, the competing "standard" model was mathematically proved to be unable to predict the bottom-pivot cone regardless of the values used for parameters in the model...
Whole-motion model of perception during forward- and backward-facing centrifuge runsJan E Holly
Department of Mathematics, Colby College, Waterville, ME 04901, USA
J Vestib Res 18:171-86. 2008..This model is based upon many of the same principles as the standard model, but includes an additional concept of familiarity of motions as a whole...
Spatial disorientation in gondola centrifuges predicted by the form of motion as a whole in 3-DJan E Holly
Department of Mathematics, Colby College, 5845 Mayflower Hill, Waterville, ME 04901, USA
Aviat Space Environ Med 80:125-34. 2009....
Effect of radius versus rotation speed in artificial gravityJan E Holly
Department of Mathematics, Colby College, 5845 Mayflower Hill, Waterville, ME 04901, USA
J Vestib Res 17:333-46. 2007..Also predicted is that head-movement direction makes a difference, with rotation outward relative to the centrifuge axis causing the least disturbance...
Head tilt-translation combinations distinguished at the level of neuronsJan E Holly
Department of Mathematics, Colby College, Waterville, ME 04901, USA
Biol Cybern 95:311-26. 2006..Combinations of other neurons, as well, are shown to distinguish motions. Relative response phases and in-phase firing-rate modulation are the key to identifying specific motions from within this infinite set of combined motions...
Vestibular coriolis effect differences modeled with three-dimensional linear-angular interactionsJan E Holly
Department of Mathematics, Colby College, Mayflower Hill Drive, Waterville, ME 04901, USA
J Vestib Res 14:443-60. 2004..Three-dimensional graphics were used to highlight the manner in which linear-angular interaction causes perceptual disturbance, and a crucial component is the Stretch Factor, which measures the "unexpected" linear component...
Perceptual disturbances predicted in zero-g through three-dimensional modelingJan E Holly
Department of Mathematics, Colby College, Mayflower Hill Drive, Waterville, ME 04901, USA
J Vestib Res 13:173-86. 2003..In addition, clockwise-counterclockwise differences did not appear in zero-g, in contrast to the differences that appear in 1-g...
Baselines for three-dimensional perception of combined linear and angular self-motion with changing rotational axisJ E Holly
Department of Mathematics, Colby College, Waterville, ME 04901, USA
J Vestib Res 10:163-78. 2000..The present analysis is consistent with, and expands upon, previous analyses of individual components of motion...
Identification of head motions by central vestibular neurons receiving linear and angular inputJ E Holly
Department of Mathematics, Colby College, Waterville, ME 04901, USA
Biol Cybern 81:177-88. 1999..However, a pair of neurons can code for a motion by the relative phases of firing-rate modulation. In this way, information about motion is enhanced by neurons combining information about linear and angular motion...
Timing of secondary vestibular neuron responses to a range of rotational head movementsJ E Holly
Department of Mathematics and Computer Science, Colby College, Waterville, ME 04901, USA
Biol Cybern 79:39-48. 1998..On the other hand, an in-phase response of three neurons can identify a single motion, for certain patterns of primary afferent convergence...
Three-dimensional baselines for perceived self-motion during acceleration and deceleration in a centrifugeJ E Holly
Department of Mathematics and Computer Science, Colby College, Waterville, ME 04901, USA
J Vestib Res 7:45-61. 1997..The results lead to several experimental questions...

- Human Spatial Disorientation and Misperception of Self-Motion in Three DimensionsJAN HOLLY; Fiscal Year: 2006..Measures of misperceived motion or orientation provide a promising arena for diagnostic testing for vestibular disorders. This project will provide tools and analyses for complex self-motion perception. ..
