Call for abstracts
We invite submission of high-quality abstracts that describe original research findings in any of the areas below:
Autonomic Nervous System - Sympathetic and parasympathetic pathways and mechanisms for control of pupil responses, effects of central and peripheral lesions
The Afferent Visual Pathway - Pupil Light Reflex components as objective biomarkers of the integrity of the afferent visual apparatus (in health and disease)
Cognitive Neuroscience - the use of pupil responses as a tool to investigate attention, arousal, perceptual load and cognitive processes
Pupil pharmacology - changes to the pupil induced by drugs acting either centrally or peripherally
Non-image forming visual pathways - including the neurobiology of ipRGCs, their synaptic connections within the retina and their central projections and functions. Role of ipRGCs in the control of the pupil response, light flux sensing and blindsight

Synthetic face adaptation reveals neural tuning of face identity

Purpose: To quantitatively investigate the neural tuning of the channels which encode face identity. Background: Prolonged viewing of a face can influence the appearance of subsequently-viewed faces. We aimed to quantify the magnitude of face adaptation for unfamiliar synthetic faces as a function of face identity and face distinctiveness.
Methods: Observers adapted to synthetic faces of a particular identity and distinctiveness. Face discrimination sensitivity was then assessed for the adapted identity (congruent condition) and novel identities (incongruent). Baseline face discrimination sensitivity was measured with a low-level noise adaptor.
Results: There was no effect of face adaptation within the incongruent condition. Congruent face discrimination thresholds, however, were significantly elevated. The magnitude of this elevation was related to the distinctiveness of the adapting face, ranging monotonically from 1.37 (least distinctive adaptor) to 2.38 (most distinctive).
Conclusions: Synthetic face adaptation resulted in an identity-specific reduction in sensitivity. Adaptation did not transfer between identities.The magnitude of the adaptation in the congruent-identity condition showed a monotonic dependence on face distinctiveness: the more distinct the adaptor, the stronger the adapting effect. This suggests a norm-based representation of faces with neural populations tuned to face identity and distinctiveness that respond with increasing magnitude as faces become more different from the mean.
