Topic

Relating Traumatic Brain Injury with Neuronal Injury via Multiscale Modeling

Abstract

Traumatic Brain Injury (TBI) may occur when head is impacted by blast-like mechanical trauma and the resulting pressure waves transmit to the interior of the brain. A major part of brain’s interior is built on over 100 billion neuron cells. Structurally, a single neuron is composed of a soft cell body (soma), fibrous dendrite branches and an axon fiber. The interior and exterior zones of neuron cells contain fluidic matrices (ECM) and various ions such as Na+, K+, Cl- and anions (A-). The cell membrane acts as the boundary of a neuron.  The movement of ions across neural membranes alters charge balance across the membrane enabling axons to generate Action Potential and Neurotransmission. Both Action Potential and Neurotransmission help neuron to communicate with other neurons. Efficient communication between neurons is the key for achieving cognitive function of the brain. In this seminar, our recent multiscale computational studies on the structural behavior of neurons, the fluidic response of ECMs, the fluid-structure interaction near neuron-ECM interface and the electrochemistry of ions in the intracellular and extracellular fluidic spaces of neurons will be presented. The probable connection between blast-induced trauma with structural, physiological and electrochemical damages in neurons will be discussed. Since electrochemical, structural or physiological damage of neurons may have direct linkage with neurological disorders, the current study will demonstrate the potential linkage between blast-like trauma and neurological disorders. 

Bio
Dr. Adnan is an associate professor in the Mechanical & Aerospace Engineering Department and director of the Multiscale Mechanics and Physics Lab (MMPL) at UTA. He earned his PhD in Aeronautics & Astronautics Engineering from Purdue University. Before joining UTA in the Fall of 2010, he was a postdoctoral research associate at Northwestern University. His current research on brain injury and neuron damage is funded by the Office of Naval Research grants and Defense University Research Instrumentation Program (DURIP) award.
