Investigating Brain Stimulation for Working Memory

This study is looking at how different types of brain stimulation might affect your working memory, which is your ability to hold information in your mind. Researchers are using a device called the NeuroConn Direct Current Stimulator Plus Multiple Channels to deliver three types of stimulation: Steep-tRAS, Flat-tRAS, and Sham-tRAS (a placebo stimulation). They want to see if one of these types of stimulation can improve the number of items you can remember after 3 hours. You might be able to join if you are between 18 and 35 years old, can speak English, and don't have certain neurological conditions. The study aims to enroll 30 participants, but its current status is unclear.

Study design
This is an interventional study with 30 participants. It is double-blinded, meaning neither you nor the researchers will know which type of stimulation you are receiving.
What's involved
You will have two study sessions. The first session involves recording brain activity (EEG) while you do a working memory task. In the second session, you will receive approximately 60 minutes of brain stimulation while performing the task.
Compensation
Not stated in the trial record.
Follow-up
The main measurement of how many items you remember will be taken 3 hours after the stimulation.

What this trial measures

  • Change in number of remembered items3 hours

    The number of remembered items, often referred to as working memory capacity, is calculated as the number of items to be remembered multiplied by the number of items successfully remembered divided by the number of total trials. The range of values is 0 to 7 where a larger number denotes a greater number of items that were remembered.
