Description
Greater than 11% of the total population of Americans age 12 and older were illicit drug users with close to 1 million suffering from cocaine use disorder in 2017 alone (SAMHSA, 2017), yet there are no effective pharmacological treatments for this disorder. Previous research from the Neisewander Laboratory in male rats found that administration of a 5-HT1BR agonist facilitates cocaine intake when given prior to a daily self-administration session, while inhibiting cocaine intake and attenuating drug-seeking behavior following 21 days of protracted abstinence, yet it is not known whether such effects are observed in female rats. Women face unique challenges in all phases of the drug addiction cycle. With respect to active drug-taking (i.e., the maintenance phase), women tend to increase their rate of consumption more rapidly than men, and female rats acquire cocaine self-administration faster than males. In part, this is due to ovarian hormone influences on the reinforcing properties of cocaine, where peak levels of endogenous estrogen hormones correspond to an increase in cocaine intake. In this study, we investigated the effects of CP94253, a selective 5HT1BR agonist, on cocaine intake across all phases of the estrous cycle in female rats. The rats were trained to self-administer cocaine (0.75 mg/kg, IV) on a fixed ratio (FR) 5 schedule of reinforcement and daily vaginal smears were taken after each session to monitor the estrous cycle. Rats were pretreated with CP 94,253 (5.6 mg/kg, IP) or vehicle prior to separate tests during each estrous cycle phase and were then either given 1-h access to 0.75 mg/kg cocaine followed by 1-h access to 0.375 mg/kg cocaine or 1-h access to 0.1875 mg/kg cocaine followed by 1-h access to 0.075 mg/kg cocaine. Similar to males, CP 94,253 decreased cocaine intake in females at intermediate doses, however, the estrous cycle phase did not alter this effect.

Description
Art is an inherent concept instilled in human nature, which utilizes the abilities of the creative mind to invent. Art has served many purposes in the history of mankind, including, but not limited to story telling, entertainment, decoration, exploration, propaganda, education, and therapy. The primary aim of this creative project was to explore the importance of the art, as a creative process, as a way to supplement academic endeavors. The idea derived from an observation made by myself that contemporary regard for art has been on a decline, which made me question if I also value art as much as I think I do, having done art in the past and recently added a studio art minor. I thought of ways to again incorporate art and the creative process into my life. I asked myself the question: can the creative process be used as a supplement to schoolwork in order to relieve stress? To explore this, an experiment was designed, which entailed my creation of drawings twice a week, accompanied by journal documentation for a full semester of college. Afterwards, analyses were done between the documented journal entries and the artworks to see if any relationships were apparent between various aspects of my life at the times of the drawings and the drawings themselves. Further research was also conducted in related areas of study and documented in written format, which cited and analyzed numerous journal articles, artworks, artists, and research papers. This included art therapy, art education, and the relationships between art and science. Results from the experiment indicated that art as a creative process allowed for the relief of stress by cleansing my mind from any concern or interferences, therefore offering myself a complete break and relaxation, effectively refreshing my mind and allowing me to resume schoolwork or other tasks more mentally taxing. In addition, the research also showed that art therapy could effectively utilize this palliative effect of art making to ease the problems of people in distress. The findings also concluded that art and science go hand in hand, which explains a lot of the similarities in methodologies utilized by scientists and artists. In conclusion, art is a paramount part of mankind in exercising the creative mind and is ubiquitous; we should learn to actively embrace it to enrich our lives.
