We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.
You can help! If you notice any innacuracies, please

R01Activity Code Description: To support a discrete, specified, circumscribed project to be performed by the named investigator(s) in an area representing his or her specific interest and competencies. R37Activity Code Description: To provide long-term grant support to investigators whose research competence and productivity are distinctly superior and who are highly likely to continue to perform in an outstanding manner. Investigators may not apply for a MERIT award. Program staff and/or members of the cognizant National Advisory Council/Board will identify candidates for the MERIT award during the course of review of competing research grant applications prepared and submitted in accordance with regular PHS requirements. |
Retinal and Central Visual Function @ University of California Berkeley
An understanding is being sought of the mechanisms underlying visual acuity and visual hyperacuity. The latter is characterized by a spatial threshold much smaller than the elements of the retinal mosaic. This kind of performance hence must have its basis in a neural processing mechanism by which small spatial differences are detected, probably at the expense of some other possible modes of information transformation. Experiments will be carried out on human observers to delineate their spatial and temporal differences detecting abilities, with such factors as exposure duration, adaptation, movement, binocularity and spatial features as parameters. Attempts will be made to identify test variables that allow the clinician to distinguish between various modes by which disease processes interfere with normal neural mechanisms of resolution and that will aid in the alleviation of resolution decrements by optical and other means.

Retinal &Central Visual Functions @ University of California Berkeley
Research is to be conducted on the visual mechanisms by which the human observer resolves fine details and accurately localizes objects in two and three dimensions. The retinal components of these abilities will be analyzed, using optical and psychophysical techniques, by distinguishing between the limits set by the discrete nature of the mosaic of retinal receptors, by the sensitivity to intensity differences that can be detected in small adjacent retinal locations, and by the interaction between retinal neural entities. Identification of Snellen visual acuity letters and stereoscopic vision require, in addition, the elaboration and relative localization of individual features, and these are functions of the cortex. The interest is in the interaction of separate features and the development of the visual attributes of two-dimensional position and three-dimensional depth. The long-term goal is twofold: (1) to specify rigorously the ultimate performance characteristics of the human visual system and to delimit the range of possible neural circuits that may serve as their substrate, and (2) to gain insight into the optical and neural processes subserving visual acuity, hyperacuity and stereoscopic localization that will aid in the differential diagnosis of patients with reduced acuity and the development of tests of etiological and prognostic value.
