© 2018, The Author(s). Rationale: Muscarinic acetylcholine receptors are known to play key roles in mediating cognitive processes, and impaired muscarinic cholinergic neurotransmission is associated with normal ageing processes and Alzheimer’s disease. However, the specific contributions of the individual muscarinic receptor subtypes (M1–M5) to cognition are presently not well understood. Objectives: The aim of this study was to investigate the contribution of M2-type muscarinic receptor signalling to sustained attention, executive control and learning and memory. Methods: M2 receptor-deficient (M2−/−) mice were tested on a touchscreen-operated task battery testing visual discrimination, behavioural flexibility, object-location associative learning, attention and response control. Spontaneous …

Multiple cancer populations frequently report cognitive impairment following treatment with chemotherapy agents (“chemo-brain”). Impaired neuropsychological performance is commonly reported in cognitive domains of attention and executive function. Understanding neural mechanisms underlying cognitive impairments is essential to developing prevention and rehabilitation strategies. Brain imaging studies frequently show chemotherapy-related impairments within the attentional control network, which is comprised of a constellation of cortical regions that govern reportedly impaired cognitive functions. In the current dissertation research, I developed a novel electrophysiology battery aimed at recording near-instantaneous neural activity within the attentional control network during cognitive task performance. Cancer patients diagnosed with hematological malignancy …

Atypical sensory perception is one of the most ubiquitous symptoms of autism, including a tendency towards a local-processing bias. We investigated whether local-processing biases were associated with global-processing impairments on a global/local attentional-scope paradigm in conjunction with a composite-face task. Behavioural results were related to individuals' levels of autistic traits, specifically the Attention to Detail subscale of the Autism Quotient, and the Sensory Profile Questionnaire. Individuals showing high rates of Attention to Detail were more susceptible to global attentional-scope manipulations, suggesting that local-processing biases associated with Attention to Detail do not come at the cost of a global-processing deficit, but …
Childhood Lead Exposure And Attention-Deficit/Hyperactivity Disorder Symptoms: A Meta-Analysis, Megan Glenn Brown
Childhood Lead Exposure And Attention-Deficit/Hyperactivity Disorder Symptoms: A Meta-Analysis, Megan Glenn Brown
Walden Dissertations and Doctoral Studies
Lead exposure during childhood is a significant global public health concern as the potential effects of exposure can result in the need for long-term treatment, diminished productivity in society, and financial strain on the health care system. There is strong evidence of a relationship between lead exposure and attention-deficit/hyperactivity disorder (ADHD); however, there is a gap in the current literature regarding the relationship between lead exposure and specific symptoms of ADHD and the strength of that relationship. The purpose of this meta-analysis was to examine and help quantify this relationship. Cohen's d was used as the standardized mean effect size …
