The primary aim of my research has been to understand how biological ion channels work. All electrical activities in the nervous system, including communication between cells and influences of hormones and drugs on cell function, are regulated by the opening and closing of ion channels. Thus, understanding how these ion channels operate will ultimately help us find the causes of, and possibly cures for, many neurological, muscular and cardiac disorders.
Connections between nerve cells in the brain often occur onto enlarged protrusions called dendritic spines. This proposal will investigate the properties of dendritic spines, and relate differences in spine properties to synaptic plasticity. This information can be used to better understand and treat neurological disorders associated with spine malfunction, as occur in some forms of mental retardation, and may help with understanding the memory loss that occurs during ageing and dementia.
