Gender And Color Specific Differences In Event Related Potentials, Abhishek Trikha
Gender And Color Specific Differences In Event Related Potentials, Abhishek Trikha
Theses and Dissertations
This project analyzed gender and color-specific differences in event-related potentials (ERPs). Previous studies have shown that males process color differently than females. In a recent study, sex differences were found in ERPs during a visual object recognition task. There were higher EEG amplitudes in females (especially P300) than males. Significant sex and color-specific differences have been found in diseases involving altered dopamine (DA) machinery. Thus, we analyzed differences between ERPs in males vs females during a color task. We also compared the color-specific differences in ERPs between males and females. Males and females participated in EEG recording sessions for 2 …

It is well known from birth that faces are salient, preferred over other stimuli, and are readily discriminated. It has also been shown that over the course of development infants’ proclivity for face discrimination is influenced by their social environment. Pascalis, deHann, andNelson (2002), for example, demonstrate that 6-month-olds are able to discriminate various monkey faces as well as human faces whereas 9-month-olds can only discriminate different human faces. Importantly, however, if 6-month-olds receive 1-2 minutes per day of familiarization with photographs of monkey faces three months later the now 9-month-olds can still discriminate unfamiliar and familiar monkey faces. Like …

Lipid composition plays an important role in fusion of vesicles to membranes, an essential process for exocytosis. Lipid head group, tail structure, and sterol content all impact the complex phase behavior of membranes. To determine the effect of lipids on fusion, we utilized the nystatin/ergesterol (nys/erg) fusion assay and stimulated fusion with a salt (osmotic) gradient. With this assay, vesicles containing nys and erg fuse with a planar membrane producing characteristic spike increases in membrane conductance.Using PE/PC (7:3) membranes, we varied cholesterol from 0-40 mol% and observed significant increases in fusion rates. In one series of experiments, membranes were formed …
