A Dynamic Efficient Sensory Encoding Approach to Adaptive Tuning in Neural Models of Optic Flow Processing
Autor: Scott T. Steinmetz, Oliver W. Layton, Nathaniel V. Powell, Brett R. Fajen
Publikováno v: Frontiers in Computational Neuroscience, Vol 16 (2022)
This paper introduces a self-tuning mechanism for capturing rapid adaptation to changing visual stimuli by a population of neurons. Building upon the principles of efficient sensory encoding, we show how neural tuning curve parameters can be continua

Decoding Estimates of Curvilinear Self-Motion from Neural Signals in a Model of Primate MSTd
Autor: Nathaniel V. Powell, Oliver W. Layton, Scott Steinmetz, Brett R. Fajen
Self-motion produces characteristic patterns of optic flow on the eye of the mobile observer. Movement along linear, straight paths without eye movements yields motion that radiates from the direction of travel (heading). The observer experiences mor

Affordance-based versus current-future accounts of choosing whether to pursue or abandon the chase of a moving target
Autor: Oliver W. Layton, Scott Steinmetz, Nathaniel V. Powell, Brett R. Fajen
Publikováno v: Journal of Vision
Affordance-based control and current-future control offer competing theoretical accounts of the visual control of locomotion. The aim of this study was to test predictions derived from these accounts about the necessity of self-motion (Experiment 1)

Exploring Uncertainty and Movement in Categorical Perception Using Robots
Autor: Nathaniel V. Powell, Josh C. Bongard
Publikováno v: Parallel Problem Solving from Nature – PPSN XIV ISBN: 9783319458229
PPSN
Cognitive agents are able to perform categorical perception through physical interaction (active categorical perception; ACP), or passively at a distance (distal categorical perception; DCP). It is possible that the former scaffolds the learning of t
