Thesis title: The use of Electroencephalography as a measure of pain and analgesia in sheep

Supervisors: Sabrina LOMAX , Peter WHITE

Thesis abstract:

Electroencephalography (EEG) has the potential to be a minimally invasive and objective measure of pain in conscious sheep undergoing painful husbandry procedures. It may enable differentiation in the efficacy of analgesic interventions and aid as a tool to answer several questions in regards to best practice on farm. This includes the age at which procedures are performed and the comparison of analgesic delivery pre or post-surgery. This project will investigate EEG, in conjunction with heart rate variability (HRV) and behavioural scoring, to assess the efficacy of this method as a measure of pain and analgesia in sheep.
