Gut microbes and brain function
The gut-brain-microbiota axis comprises an extensive communication network between the brain, the gut, and the microbiota residing there. If the composition or the diversity of the gut microbiota is impaired, this can have negative consequences for host health and has been associated with disorders …

Emotion, Depression, and Asymmetric Brain Function
… that depression is associated with abnormal functional asymmetries in frontal cortex, functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET) studies have largely failed to identify specific brain regions showing this effect. This failure likely stems in part from …

Modulatory effects of GluN1 autoantibodies on brain function
… circulatory system are able to cross the blood-brain-barrier (BBB) and enter the central nervous system (CNS) to modulate brain function, as supported by findings in vaccination strategies for Alzheimer’s disease (AD) in mouse models and autoimmune disease models. Our laboratory has previously …

Use of Brain Function Concepts by Social Studies Teachers
… in the study was the degree to which selected brain-function concepts had been applied to teaching techniques by Des Moines area secondary social studies teachers who responded to an opinionnaire. These were three primary questions: (1) How aware were respondent teachers of the selected …

Algorithms for enhanced spatiotemporal imaging of human brain function
Studies of human brain function require technologies to non-invasively image neuronal dynamics with high spatiotemporal resolution. The electroencephalogram (EEG) and magnetoencephalogram (MEG) measure neuronal activity with high temporal resolution, and provide clinically accessible signatures of …

Characterising In Vivo Brain Function Following Mild Traumatic Brain Injury
Traumatic brain injury (TBI) is the most complex disease in the most complex organ and a public health emergency. Sometimes called a silent epidemic, there are at least 50 million TBIs each year globally. This incidence translates to half the world’s population having at least one TBI in their …

Effects of Regional Deletion of Rab3A-interacting Molecule and PTEN on Brain Function
… from targeted neuronal populations to study brain region-specific behavioral functions. To this end, I utilized two different conditional knockdown techniques to study the role of the presynaptic active zone molecule Rab3A-interacting Molecule (RIM1) and the phosphatase and tensin homologue …

Assessing Neuronal Synchrony and Brain Function Through Local Field Potential and Spike Analysis
… of neuronal activity related to essential brain functions like sensory processing and cognition. Important principles and theories have emerged from these findings, including the communication through coherence hypothesis, which proposes that synchronous oscillations render neuronal …

The Effect of Embryonic Alcohol Exposure on Brain Function and Behavior in Zebrafish Strains
… is how does embryonic alcohol exposure alter brain function and behavior in different zebrafish strains? My first experiment explored the influence of environmental factors salinity and olfactory cues on zebrafish behavior. This was conducted to reduce experimental error variation and create …

Exploring the combined use of electrical and hemodynamic brain activity to investigate brain function
… between electrical and metabolic aspects of brain functioning in health and disease, measured with QEEG and NIRS, in order to evaluate its clinical potential. First the limitations of NIRS were investigated, depicting its susceptibility to different types of motion artefacts and the inability …

Developing disease-state liver models to determine the effects on brain function in vitro
… gut and the circulatory system, and due to the brain’s high perfusion rate, the liver’s function as a regulator for blood composition is highly important for the brain. Although the blood brain barrier blocks certain large molecules from entering into the organ, small molecules, such as ammonia, …

Complex, yet Resolved: Time-, Frequency-, and Information-resolved Approaches to Brain Function and Human Consciousness
Different perturbations of the brain’s delicate functioning, ranging from transient pharmacological interventions to severe trauma, can result in altered states of consciousness. To illuminate how the neurobiology and organization of the human brain support consciousness, we need to identify …

Prevalence and seasonal variation of severe childhood protein calorie malnutrition in Khartoum : implication for brain function
… influencing demographic factors and impact on brain function with use of electroencephalogram (EEG) assessment before and after clinical and nutritional interventions. All 466 children admitted to the Khartoum Teaching Hospital and Ibn Oaf Children Emergency Hospital during July to September …

The Association between the Immune Proteome and Brain Function and Socioemotional Development in 5-Year-Old Children
… a critical developmental period of rapid brain and socioemotional development. Despite growing evidence of immune processes in brain development, most research has focused on prenatal exposure or adult populations and has examined a limited number of classical inflammatory markers. …

Investigating the effects of a 6-month aerobic exercise intervention on brain function and memory in older adults
… know little about how aerobic exercise affects brain function and whether functional changes are behaviorally relevant. In the present study, we investigated the effect of a 6-month aerobic exercise intervention on episodic memory retrieval using fMRI in healthy older adults. Specifically, 137 …
