"Improving cognition using non-invasive brain stimulation" We are investigating the use of a non-invasive brain stimulation technique which has been identified as improving key cognitive functions, such as attention and memory. We are hoping we can enhance performance on certain tasks using brain stimulation. The study is being conducted at the Institute of Psychiatry (IoP) by Asif Jamil and Natasza Nalesnik. We are looking for healthy male individuals, age 30 - 50, who are right-handed and willing to take part in two MRI scanning sessions, lasting approximately 90 minutes each. During ONE of the two sessions, we will deliver a light current to your brain (no more than 2,000 milliamps). Subjects will experience a light 'tingle' sensation in the head during the stimulation, which will last 30 minutes. During the stimulation, you will be asked to perform an attention task. In the other session, you will not receive any stimulation, but will still be asked to do the attention task. tDCS (transcranial direct current stimulation) is a painless procedure and has been widely used throughout the world for 20 years. tDCS works by producing a brief direct current that activates the part of the brain under the electrode. In this study, we will stimulate the prefrontal cortex, which is a part of the brain important to learning and memory. We will compensate each subject with £40 for taking part in this study.
