Resolving single cone inputs to visual receptive fields [PDF]

Nature Neuroscience, 2009
With the current techniques available for mapping receptive fields, it is impossible to resolve the contribution of single cone photoreceptors to the response of central visual neurons. Using adaptive optics to correct for ocular aberrations, we delivered micron-scale spots of light to the receptive field centers of neurons in the macaque lateral ...

Single-cone obturation technique: a literature review [PDF]

RSBO, 2013
The technique of single-cone obturation is a technique that uses only the master cone. There have been an increase in its use, especially by employing larger cones with larger taper sizes that best match the geometry of rotary nickel-titanium systems (NiTi), not requiring the use of accessory cones, thus reducing the time spent in endodontic obturation.

Single cones give rise to multi-cone types in the retinas of fishes

Scientific Reports
Retinal cone photoreceptors are specialized neurons that capture light to begin the process of daylight vision. They occur as individual cells (i.e., single cones), or as combinations of structurally linked cells, such as the double and triple cones ...

Photonic antiferromagnetic topological insulator with a single surface Dirac cone

Science Advances
Antiferromagnetism, characterized by alternating magnetic moments, has garnered renewed interest for its potential applications in spintronics and axion electrodynamics. Its synergy with topology may yield an exotic topological phase unique to a certain magnetic order, termed antiferromagnetic topological insulators (AF TIs). A hallmark signature of AF

Adaptation of a Single-Cone in Prepared Teeth with Two Reciprocating Systems. [PDF]

Iran Endod J, 2022
Introduction: This ex vivo study aimed to compare the adaptation of single gutta-percha cone in teeth prepared with the Wave One Gold and Reciproc Blue reciprocating systems through cone-beam computed tomography.

Photostimulation of Single Cones [PDF]

The Journal of General Physiology, 1960
As far as we know, no experimental study exists concerning the functional activity of single cones of the vertebrate retina. It has not been directly proved that the cones are photosensitive, although such an assumption has been generally accepted mainly because of morphological reasons.

An Active Set Method for Single-Cone Second-Order Cone Programs [PDF]

SIAM Journal on Optimization, 2006
We develop an active set method for solving second-order cone programs that may have an arbitrary number of linear constraints but are restricted to having only one second-order cone constraint. Problems of this form arise in the context of robust optimization and trust region methods.

Thin-layer detection from the cone resistance rate of change [PDF]

, 2022
True determination of soil parameters for thin clay layers in sand or silts from CPTU measurements is challenging. Cone resistance in thin layers is influenced by the surrounding layers resulting in unrepresentative measurements.

GRF2 Is Crucial for Cone Photoreceptor Viability and Ribbon Synapse Formation in the Mouse Retina

Cells, 2023
Using constitutive GRF1/2 knockout mice, we showed previously that GRF2 is a key regulator of nuclear migration in retinal cone photoreceptors. To evaluate the functional relevance of that cellular process for two putative targets of the GEF activity of ...

Electrical responses of single cones in the retina of the turtle [PDF]

The Journal of Physiology, 1970
1. Intracellular recordings have been made from single photoreceptors in the retina of the turtle. Histological sections of the retina made after injection of dye through the recording electrode reveal dye in the inner segments of single cones.2. Following a brief flash of light the cone undergoes a hyperpolarization which is graded with the intensity ...
