Variations in photoreceptor throughput to mouse visual cortex and the unique effects on tuning
Scientific Reports, 2021 Visual input to primary visual cortex (V1) depends on highly adaptive filtering in the retina. In turn, isolation of V1 computations requires experimental control of retinal adaptation to infer its spatio-temporal-chromatic output.

Precise multimodal optical control of neural ensemble activity. [PDF]
, 2018 Understanding brain function requires technologies that can control the activity of large populations of neurons with high fidelity in space and time. We developed a multiphoton holographic approach to activate or suppress the activity of ensembles of ...

Developmental Dynamics, EarlyView.Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Docosahexaenoic acid promotes photoreceptor differentiation without altering Crx expression [PDF]
, 2006 PURPOSE: The precise molecular cues required for photoreceptor development are still unknown. Pax6 and Crx are essential during early retinal development and for photoreceptor differentiation, respectively.

Science, 2019 Evolution![Figure][1] Noctilionoid bats, including the fishing bat shown, have complex mechanisms for eye pigment evolution. PHOTO: CHRISTIAN ZIEGLER/MINDEN PICTURES Opsin genes encode photoreceptor proteins that enable perception of dim light by rod cells and color by cone cells in the eye.

Environmental Toxicology and Chemistry, EarlyView.Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Australasian Journal of Dermatology, EarlyView.ABSTRACT Background/Objectives Post‐inflammatory hyperpigmentation (PIH) is a frequent sequela of acne in patients with skin of colour (SOC). While sunscreen is widely recommended for PIH prevention, little is known about real‐world sunscreen practices in this group. This study aimed to evaluate sunscreen use, barriers and factors influencing adherence

Bleached pigment activates transduction in salamander cones. [PDF]
, 1995 We have used suction electrode recording together with rapid steps into 0.5 mM IBMX solution to investigate changes in guanylyl cyclase velocity produced by pigment bleaching in isolated cones of the salamander Ambystoma tigrinum.

The Na+/Ca2+, K+ exchanger NCKX4 is required for efficient cone-mediated vision [PDF]
, 2017 Calcium (Ca2+) plays an important role in the function and health of neurons. In vertebrate cone photoreceptors, Ca2+ controls photoresponse sensitivity, kinetics, and light adaptation.
