Research

Please note that David Nutt now works at Imperial College London. For further information please refer to the Imperial College website.


Experimental approaches range from receptor binding assays to collecting images of the human brain. The techniques in use include CT (Computerised Tomography), PET (Positron Emission Tomography) and SPECT (Single Photon Emission Computed Tomography).

PET is particularly useful in studying the effects of drugs and brain neurochemistry. Using different compounds, PET shows blood flow, oxygen and glucose metabolism, and the concentration of drugs or neurotransmitters. Blood flow and oxygen and glucose metabolism reflect the amount of brain activity in different regions, whilst determining the site and turnover of drugs and neurotransmitters gives insights into how they act in the brains of patients and in normal subjects.

David's particular areas of research focus on brain circuits and receptors in anxiety and addiction, and on the pharmacology of sleep.

This involves the study of GABA receptors, using labelled subtypes of GABA 5, and serotonin, or 5-HT, receptors. Type 1 5-HT receptors seem to be especially important in depression and the action of anti-depressants. Other projects underway investigate different aspects of anxiety, addiction and sleep.



Current projects include:
  • GABA and 5-HT1A receptors in anxiety using PET
  • Dopamine and opiate receptors in addiction

Possible future projects and direction of research:
  • Stress regulation
  • Human models of anxiety
