Research Interests:
Dr Moorhouse's broad interest are in the molecular and cellular basis of neuronal excitability, focussing on how membrane transporters and ion channels contribute to electrical and chemical signalling in the brain. He leads the Neurobiology Research Lab that aims to develop improved and novel strategies to treat different brain disorders by gaininmg greater understanding of underlying cellular mechanisms. In collaboration with colleagues at UNSW and beyond, we use a range of techniques, including electrophysiology, cell culture and mutagenesis, live cell imaging, biochemical and histological approaches and behavioural analysis. Dr Moorhouse and his colleagues have published over 40 journal articles in this area with over 1300 citations.  Dr Moorhouse's current research focus is on; i) the role of KCC2 transporter in Cl- homeostasis and neuronal inhibition in health and disease;  ii) the molecular basis of ion permeation in GABA and glycine receptors, and iii) novel flavonoid modulators of glycine receptors.

Broad Research Areas:
Neuroscience, Cell Physiology, Ion Channels, Membrane Transport Proeteins, Receptors. 

Qualifications:
BSc, PhD Syd

Society Memberships & Professional Activities:
Dr Moorhouse is a regular member of the Australian Neuroscience Society (ANS) and the Australian Physiological Society (AuPS), and a periodic member of the Australian Biophysics Society.  He regularly reviews grants and research papers for a variety of National and International funding bodies (e.g., NH&MRC, ARC, Wellcome Trust) and scientific journals (e.g., Neuropharmacology, Pain, Journal of Physiology, British Journal of Pharmacology) and is on the editorial review board of the Journal of Biological Chemistry.

Research Activities

Brain function is a delicate balance of neuronal excitation and inhibition. The schematic diagram above illustrates inhbitory neuronal responses mediated via the neurotransmitter GABA, and how these are affected by the neuronal Cl- transporters KCC2 and NKCC1. In neonatal neurons (left, A), KCC2 is absent and NKCC1 mediated Cl- influx results in GABA mediated depolarization and excitation. In most adult neurons (middle, B), KCC2-mediated Cl- efflux dominates Cl- homeostasis resulting in GABA mediated hyperpolarization and inhibition (A&B adapted from Ben-Ari, 2002). (C, right) KCC2 is…
