It is well known that many of our biological processes are regulated by circadian rhythms. Photic input is the best characterized stimulus for entraining circadian rhythms. In mammals, light input is conveyed to a brain structure called the suprachias . . .

Many of our biological processes are driven by endogenous 24-hour cycles known as circadian rhythms. Recent studies implicate dopamine signaling as a key mediator of entraining circadian activity cycles to feeding. To measure the influence on food on . . .

Obesity is associated with a number of health problems and is now an epidemic across most of our country. To understand this issue we ask the question: what can cause overeating? Dopamine receptors are distributed across several regions in the brain a . . .

As obesity rates skyrocket throughout the world, there is a race to understanding the neural circuitry behind such behaviors, so that one day this understanding of the brains functioning may be targeted for clinical treatments for the disease. This st . . .

Many biological processes are driven by endogenous 24-hour cycles known as circadian rhythms. Recent studies implicate dopamine signaling as a key mediator of entraining circadian and ultradian rhythms, particularly of activity. The system behind ligh . . .

Although the enzyme polyphenol oxidase (PPO) is well studied for its role in postharvest browning of commercial crops, its specific physiological function in plants is poorly understood. Previous research on the physiological role of PPO in walnut (Ju . . .

To better understand the neural mechanisms for human physiology, an invertebrate’s control on its cardiovascular system should be investigated. The leech’s heartbeat is controlled by segmental ganglia and has a phase delay in its peristaltic heartbeat . . .
