Dynamics of perceptual decision making
During this study you will learn and perform a task that involves judging the direction of motion of clouds of moving dots. You will participate in a maximum of 4 sessions; first you will learn how to do the task on a computer. Then you will do 1-2 sessions performing the task while we record your brain activity using magnetoencephalography (MEG). MEG is a safe neuro-imaging technique that records the weak magnetic fields produced by the synchronised firing of neurons in the brain. MEG sessions will last up to 2 hours. Finally, we will make a 3D image of your brain using magnetic resonance imaging (MRI) which we will use to localise the neural generators of the MEG signals.
We are looking for
Right-hand, fluent in English, aged 18-45, normal or corrected-to-normal vision (eyeglasses, contact lenses), no epilepsy, not pregnant, able to enter MRI and MEG environments (we will check this with a questionnaire if you are interested in participating).
You’ll be compensated for your time.
