Introductory description

This module will provide introductory understanding of the nervous system, concentrating on the physiology and cell biology of neurones.

Module aims

This module will cover the cell biology of neurons and glial cells of the nervous system. It will provide insight into the basic structure and function of these cells and describe the cell biological process that give rise to them (neurogenesis), allow them to migrate to their correct location, to establish synaptic and other contacts (axon guidance), to satisfy metabolic needs at sites distant from the cell body (axonal transport, localised protein synthesis and receptor trafficking). The aim of the module is to introduce the students to how the wiring of the nervous system arises through an understanding of the differentiation and development of individual cell types. Such process can go awry and give rise to neurodevelopmental conditions such as autism. The module will provide valuable knowledge that will aid student learning throughout the Neuroscience degree. While not a compulsory module, students of Neuroscience will be expected to take this module, but not taking it does not preclude students from other degree streams transferring to Neuroscience at the end of Year 1.
