E-Prime Extensions for fMRI 3.0 (EEfMRI) Single-User License. Permits experiment design on one machine at a time as well as data collection on one machine at a time (the machine at the MRI scanner).
Required: E-Prime 3.0
EEfMRI includes several features to make fMRI experiment development, data collection, and analysis of fMRI data easier. Some of those features are:
- A built-in PackageCall that allows for a drag-and-drop element that can be positioned at the start of the experiment to synchronize the experiment with the scanner trigger pulse
- Easier logging of experimental events that are time-locked relative to the scanner trigger which makes for significantly easier data analysis
- A pre-built menu system that lets the experimenter group a battery of tasks together in a single experiment rather than forcing the experimenter to close/open E-Prime tasks at the end of each run to choose a different paradigm, which saves time in the scanner
- Using the pre-built menu system, allows the experimenter to stop/restart tasks in a controlled way rather than losing all data from an entire run by exiting the task
- A pre-built E-Prime experiment called MapperOne based on a cited and published fMRI research that produces robust and reliable regional activations. This experiment can be used to collect data directly from the task, but most importantly is completely editable. This allows any user to take the basic structure of the task and insert their own tasks into the battery and/or remove existing tasks to fit with the research study. This gives the researcher the ability to start from an “ideal” experiment structure in E-Prime, rather than having to completely start from scratch. The experiment contains the following block-level tasks:
- a visual task designed to activate the occipital cortex
- a bimanual motor task designed to activate motor areas
- a verb generation task designed to activate speech processing areas
- an n-back task designed to activate areas associated with working memory and executive function
- an emotional pictures task designed to provoke strong emotional responses that typically activate limbic structures.
