Research & Services | Understanding Neuron Signaling Mechanisms for Insight into Conditions such as Stroke, Epilepsy, Depression and Drug Addiction
Project ID : 6-2010-2438
Description of the technology
In animals, neurons working together as a nervous system are responsible for the ability to perceive and respond appropriately to environmental changes.
Sensory neurons perceive the changes and transform the information into electrical signals which are propagated and processed in the nervous system to finally produce physiological and behavioral responses.
Signaling mechanisms within neurons, between neurons, and between neurons and target organs enable the neurons to perform this complicated process.
Defects in the molecular components enabling signal sensation, transmission, or processing are highly debilitating.
Understanding the function of neuronal signaling molecules requires analysis of their function at the molecular, cellular, and whole animal level.
Many different tools and experimental systems are employed in this work including: electrophysiological responses from intact organisms, brain slices, primary and established cell cultures, or from recombinant molecules expressed in heterologous expression systems.
Members of the group also use molecular biology, biochemistry, genetics, and behavioral analysis on mammalian cells and tissues and on genetically tractable model organisms.
The work provides insights into such pathological conditions as stroke, epilepsy, depression and drug addiction which may facilitate the design of better treatments for these diseases.
