We measured the ability to infer structure from motion (SFM) in several directions in three-dimensional color space. Only motion cues are useful to subjects in performing this three-dimensional shape-identification task. We report the following results: (1) SFM performance is at chance for equiluminant stimuli that isolate short-wavelength-sensitive cones. Hence the short-wavelength-sensitive-c...

We used fMRI to examine the neural correlates of subjective reversals for bistable structure-from-motion. We compared transparent random-dot kinematograms depicting either a cylinder rotating in depth or two flat surfaces translating in opposite directions at apparently different depths. For both such stimuli, the motion of dots on the different apparent depth planes typically appears to revers...

Sensitivities to moderately intense stimuli representing four taste qualities to man were determined for 79 hamster chorda tympani fibers. Some fibers were very sensitive to sucrose, sodium chloride, or hydrochloric acid, but none were very sensitive to quinine. These sensitivities were not randomly distributed among fibers: the sucrose sensitivity was separated from and negatively correlated w...

Evaluative conditioning (EC) is a change in the evaluation of a stimulus after the stimulus co-occurred with affective stimuli. The present research examined whether EC of one stimulus depends also on the co-occurrence of another stimulus with positive or negative stimuli. We paired two target people with affective stimuli. We found that a person who appeared eight times with positive stimuli a...

In the last few decades, polymeric nanoparticles have been emerged as a most promising and viable technology for targeted controlled delivery of drugs well bioactive compounds such genes, drugs, nucleic acids proteins among other things, in biomedical pharmaceutical applications. They not only improve solubility, bioavailability, circulation time previous medications, but they can also be tailo...

Abstract Stimuli‐responsive, optically‐active colloidal systems are convenient signal transducers capable of monitoring environmental changes at the nanoscale. We report on coupling chemo‐thermal cycloaddition reaction with temperature‐sensitive, DNA‐coated gold nanoparticles. found that concentration chemical fuel, dictating temperature mixture, is a primary ingredient in controlling extent re...

J Neurophysiol 108: 3206–3220, 2012. First published September 5, 2012; doi:10.1152/jn.00916.2011.—The relationship between taste receptor cell (TRC) Ca concentration ([Ca ]i) and rat chorda tympani (CT) nerve responses to salty [...

Epigenetic modifications to the genome, including DNA methylation and histone modifications, occur in response to external stimuli. Reproductive function is highly sensitive to environmental conditions including season, diet, hormonal changes, and exposure to chemical contaminants. GnRH neurons, which play a key role in reproduction, are particularly sensitive to various environmental stimuli. ...
