Principal bundle geometry of qualia: Understanding the quality of consciousness from symmetry.. Qualia, the subjective qualities of experience, pose a fundamental challenge to scientific explanation. A promising approach is to characterize qualia by their relational structures rather than their intrinsic nature. Assuming the structure of qualia is characterized by the geometry of neural representations, we posit that this geometry is fundamentally organized by symmetry. We propose that the principal bundle, induced by a symmetry group G acting on a neural network's state space, is the essential mathematical object uniquely characterizing this geometric structure. The core mathematical princ…

Dose-Response Characteristics of Retinal Inactivation Due to Intravitreal Injections of Tetrodotoxin in Nonhuman Primates.. Purpose Temporary retinal inactivation of the fellow eye with intravitreal tetrodotoxin (TTX) has shown promise as a treatment strategy for deprivation amblyopia in mouse and cat models. The purpose of this study was to evaluate the duration of retinal inactivation achieved with different doses of TTX in nonhuman primates (NHPs), while also assessing functional and structural measures of vision to determine the safety of this treatment approach. Methods Three adult and four infant NHPs received varying doses of TTX (115-4800 ng) via intravitreal injection. Inactivation…
