  • Men needed for a brain study (COMT Study)

    If you take part, we will ask you to: Provide a cheek swab (to see which form of the gene you have) then, if suitable, come to the lab and: Complete some questionnaires; Take a single tablet (either a drug or a dummy pill) and carry out simple reward tasks and tests of the processing of emotions.

  • Research into emotional processing – the effects of a cognitive enhancer

    A BIT TENSE OR WORRIED? We are looking for healthy volunteers aged 18-50 years to take part in a study investigating how a single dose of the medication losartan affects learning and information processing, using computer tasks and EEG. Losartan is currently used to treat high blood pressure. However, we think that it may also enhance the effectiveness of psychological therapies such as Cognitive-Behaviour Therapy. The study involves two appointments of about 3 hours in total.

  • Men needed to study the body’s response to an acute stressor.

    The study takes about two and a half hours. No drugs are involved. Our longer-term objective is to see how acute stress interacts with a person’s genes, and with medication, to affect attention and memory. However, first we need to decide how best to induce stress in the laboratory, and see how the body responds to it

  • Are you interested in how the brain works? Men needed!

    If you take part, we will ask you to: - Provide a cheek swab (to see which form of the gene you have) then, if suitable, come to the lab and: - Take a single dose of a drug or a dummy pill; - Fill in some questionnaires and give samples of saliva; - Complete tasks of mental maths, memory and reward, while in an MRI brain scanner. The study will take one afternoon (around 3.5 hours).

  • The effect of prucalopride on emotional processing

    We are investigating the effect of a single dose of prucalopride, a drug used currently used to treat constipation, on emotional processing. The study involves a one-hour screening visit to determine your eligibility to take part, followed by a five-hour test visit.

  • Visual learning study

    ARE YOU INTERESTED IN HOW YOUR BRAIN WORKS? We are looking for healthy volunteers to improve our understanding of the human brain’s visual learning mechanisms. The study would take a maximum of 2 hours of your time consisting of a single MRI scan. You would be asked to lie still in a scanner and perform some simple tasks involving responding to visual stimuli by clicking buttons. If you are interested and would like more information please contact Caroline Nettekoven (

  • Lamotrigine and Brain Imaging Study: Healthy Volunteers Needed

    This project is about studying the effects of a single dose of oral lamotrigine, a commonly prescribed medication for epilepsy and bipolar depression, on brain activity using brain imaging technology. The study would involve 2 visits lasting approximately 1 and 5 hours, respectively. Ethics Approval Reference: R49749/RE001

  • MRI study: seeking healthy controls and those who have recovered from anorexia nervosa

    We’ll be scanning you in an MRI scanner, which is safe and non-invasive. Most of the scans will simply require you to lie still, but we will also ask you to do a task which measures compulsivity. Compulsivity is repetitively performing actions which aren’t rewarding or good for you. If you are interested in participating in this study we’d like to hear from you!

  • Can brief daily mental exercises change the way the human brain processes certain kinds of information?

    The aim of this study is to investigate the effects of certain brief mental exercises on the way in which the brain processes specific kinds of information. We are looking for healthy participants (both male and female), aged 18 to 65 years. In order to participate, you must be in good health, not be regularly engaged in any kind of formal mental exercises (e.g. yoga, meditation, mindfulness practices, positive psychology exercises, psychotherapy etc.) and you must not have a history of any mental disorder (such as depression, anxiety disorder, or eating disorder). You would be invited to the Department of Psychiatry (Warneford Hospital) for two study sessions. Both sessions would take approximately 60 to 90 minutes. Between the sessions you would be assigned a brief mental exercise (taking approximately 10 minutes per day) and you would be asked to carry out this exercise each evening for 7 days. After practising for 7 days, your performance on a range of computerized psychological tasks would be assessed. If you are interested and would like more information, please contact Dr Alexander Kaltenboeck ( at the Department of Psychiatry. Ethics Approval Reference: R49254/RE003
