The Role Of Oxidative Stress And Signal Transduction In Chemotherapy-Mediated Cognitive Impairment In The Menopause Rat Model, Ciara Bagnall
The Role Of Oxidative Stress And Signal Transduction In Chemotherapy-Mediated Cognitive Impairment In The Menopause Rat Model, Ciara Bagnall
Dissertations, Theses, and Capstone Projects
Systemic chemotherapy treatment is associated with long-term cognitive impairment in breast cancer survivors. While many studies have established the forms of cognition and corresponding regions in the brain most affected, very little is revealed about the potential molecular mechanisms that mediate these changes. The effects of systemic treatment on the brain is likely attributed to many different mechanisms including oxidative stress and immune dysregulation. Earlier studies from our lab have investigated the effects of the chemotherapy cocktail doxorubicin and cyclophosphamide (AC Chemotherapy) in an ovariectomized menopause animal model of ‘chemo brain’ (Salas-Ramirez et al., 2015). We observed that animals injected …

MSU Graduate Theses
Alzheimer’s disease (AD) is a progressive, neurodegenerative disease that is characterized by progressive loss of memory and cognitive function. The causative factors of this disease include modifications in neuronal cell metabolism, such as the progression of neurotic injury by amyloid beta (Aβ), and tau tangle deposition in the brain. Recent studies show that brain atrophy and other pathologic conditions are responsible for dementia in older individuals (80 years of age or older). Non-pharmacological interventions may have a role in both the prevention and slowing disease progression in AD. The role of exercise training in disease prevention has been evaluated in …
Sleep, And Its Relation To Non-Motor Deficits In Patients With Cerebellar Ataxia, Akshata Sonni
Sleep, And Its Relation To Non-Motor Deficits In Patients With Cerebellar Ataxia, Akshata Sonni
Doctoral Dissertations
The cerebellum is a highly connected structure, and its involvement in sleep – which is a dynamic process that is modulated by a complex set of neural systems – can come about through a number of neural pathways. We conducted two studies aimed at furthering our understanding of cerebellar involvement in sleep behavior and physiology, as well as measuring the impact of poor sleep on mood and cognition in patients with cerebellar degeneration. First, by means of an online battery including measures of sleep and neuropsychiatric function, we collected data from 176 patients with cerebellar ataxia. We found strong evidence …

Human-Like Behavior And Cognition: Not A Good Starting Point, Magnus Helgheim Blystad
Animal Sentience
Chapman & Huffman make use of observations and studies that show how humans may not be as unique in our behaviour and cognition as previously thought. I wholeheartedly agree that our uniqueness might be small and that if it exists, it should not give our species any right to act cruelly towards other animals. However, this kind of logic can be problematic. I present a few of the issues in this commentary.

Many species exhibit prosocial behavior , in which one individual’s actions benefit another individual, often without an immediate benefit to itself. The neuropeptide oxytocin is an important hormonal mechanism influencing prosociality in mammals, but it is unclear whether the avian homologue mesotocin plays a similar functional role in birds. Here, we experimentally tested prosociality in pinyon jays (Gymnorhinus cyanocephalus), a highly social corvid species that spontaneously shares food with others. First, we measured prosocial preferences in a prosocial choice task with two different pay-off distributions: Prosocial trials delivered food to both the subject and either an empty cage …

INTRODUCTION: We examined associations between magnetic resonance imaging (MRI) markers of cerebrovascular disease and neurodegeneration with mild cognitive impairment (MCI) diagnosis at baseline and conversion from normal cognition to MCI at follow-up.
METHODS: Framingham Offspring participants underwent brain MRI and neuropsychological assessment at baseline (n=1049) and follow-up (n=561). Participants were classified at baseline and at follow-up as cognitively normal or MCI using sensitive neuropsychological criteria. White matter hyperintensity (WMH) volume, covert brain infarcts, hippocampal volume, and total cerebral brain volume were quantified.
RESULTS: Baseline measures of WMH and hippocampal volume were associated with MCI status cross-sectionally and also with conversion …
