Examining The Role Of Chronic Stress In Cancer Progression And Metastasis: P53 As A Potential Mechanism, Jillian R. Dean
Examining The Role Of Chronic Stress In Cancer Progression And Metastasis: P53 As A Potential Mechanism, Jillian R. Dean
Behavioral Neuroscience Honors Papers
The influence of stress on the development and progression of cancer has been a longstanding hypothesis. Chronic stress can have a significant impact on the immune system and inflammatory response, potentially leading to decline of the body's immune capabilities (Segerstrom & Miller, 2004). Stress activates the hypothalamic-pituitary-adrenal (HPA) axis, which triggers the release of stress hormones, such as cortisol (Smith & Vale, 2006). When chronically activated, this can lead to corresponding changes in the immune system, including decreased activity of natural killer cells, which play a crucial role in identifying and destroying cancer cells. Chronic inflammation has also been shown …
Cognitive And Neural Development In A Rodent Model Of Ptsd From Maternal Maltreatment, Nhi Doan
Cognitive And Neural Development In A Rodent Model Of Ptsd From Maternal Maltreatment, Nhi Doan
Behavioral Neuroscience Honors Papers
Childhood neglect influences development and increases the risk for and severity of mental illness. Previous study has shown that early life stress (ELS) alters stress circuitry, elevates basal stress hormone, and impairs regulation of the HPA. In this study, we seek to understand the impacts of decreased quality of care and trauma on the cognitive and neural development of rats at adolescence. We used a 1-week limited bedding protocol to induce fragmented care in dams and a 10-minute exposure to fox odor to induce stress in offspring later. Memory function and patterns of brain activity following stressor exposure were assessed …
Implicit Bias Through The Lens Of Electroencephalography, Hope Cooper
Implicit Bias Through The Lens Of Electroencephalography, Hope Cooper
Behavioral Neuroscience Honors Papers
Unconscious or implicit bias is a part of everyday life. All human beings both exhibit implicit bias and (some more than others) are also the victims of it. Due to the way humans have evolved implicit bias will never be something that ceases to exist. Thus, it is important that neuroscience and social science closely study how it works and how to curb the behaviors caused by implicit bias. In the following research EEG (electroencephalography) was used alongside a weapons IAT (Implicit Association Test) to examine specific neural components that may correlate with higher bias scores on the IAT. Specific …
Combined Effects Of Rearing Environment And Lead (Pb2+) Exposure On Visuospatial Learning And Memory In Rats, Nicholas Tolman
Combined Effects Of Rearing Environment And Lead (Pb2+) Exposure On Visuospatial Learning And Memory In Rats, Nicholas Tolman
Behavioral Neuroscience Honors Papers
Critical periods of neural development occur during early postnatal life that correspond with increases in synaptic plasticity and the formation of neural circuits needed for learning and memory. This development can be profoundly influenced by experience and negatively affected by environmental toxins. Environmental enrichment and lead exposure inversely affect mediators of synaptic plasticity, which suggests that enrichment may have an attenuating effect on lead induced cognitive deficits. A wealth of evidence has indicated that exposure to excessive amounts of inorganic Pb2+ during early development can produce long lasting cognitive deficits in humans. Evidence also suggests that children raised in an …
The Effects Of Acute Nicotine Administration On Memory Formation And Neural Activity In The Hippocampus, Perirhinal Cortex, And Medial Septum: Implications For Neurodegenerative Disorders, Matthew Wishnoff
Behavioral Neuroscience Honors Papers
Within the general public, nicotine is commonly thought of as a harmful molecule due to its role in tobacco addiction. However, nicotinic stimulation of the cholinergic system has also been shown to enhance cognitive functioning. This enhancement is thought to be caused by an increase in the release of the neurotransmitter, acetylcholine (ACh), which is responsible for mediating a variety of cognitive processes, such as REM sleep and memory formation. Recent research by Melichercik and colleagues shows that systemic nicotine administration enhances memory acquisition for both object location and object recognition memory in rats, as assessed by a modified version …
Do Athletes Respond Differently To Academic And Social Stress? An Examination Of Cortisol And Perceived Stress Throughout A Semester In College Athletes And Typical College Students, Rita Rose Holak
Behavioral Neuroscience Honors Papers
In order to be a successful athlete, you must be able to perform well under stressful situations. Are athletes also better at responding to stress under other circumstances such as social and academic stress? The present study investigated the impact of exercise on salivary cortisol and perceived stress in college students. Cortisol was sampled throughout a semester as well as before and after a laboratory‐based stress test during the final exam period. It was found that athletes had the largest increase in cortisol between baseline and the final exam period and the sedentary students had the smallest increase. Also, cortisol …

As instructors who teach laboratory courses in biological psychology/behavioral neuroscience, we have often been at a loss to find appropriate experiments where students are able to play both the role of experimenter and subject. The difficulty arises because there are few biological parameters representing CNS activity that can ethically be examined in human participants. As a result, the go-to experiments that allow students to act as both experimenter and subject tend to be electrophysiological in nature (e.g., EEG, GSR, etc.). It was our desire to create a laboratory module that would allow students to collect and analyze a biochemical measure …
