<p>Since its inception, the <em>StudyForrest</em> dataset has grown
appreciably through both internal and external contributions. Made
available are raw data, preprocessed data, and an extensive collection of
annotations of the movie. Often, multiple data types are available for the
same set of participants &mdash; for example, multiple fMRI scans of up to
10 hours total per participant.</p>
<p>Below is an overview of all major components of the <em>StudyForrest</em>
dataset. This includes data relating to brain structure, brain function,
and movie stimulus properties. Further details for each data type can be
found in the linked publications.</p>

<p>Two principle data modalities were acquired: Blood oxygenation level
dependent (BOLD) fMRI scans, continuously capturing brain activity at
a spatial resolution of 1.4 mm, and physiological recordings of heart
beat and breathing. For technical validation, all measurements are
also available for a full-length gel phantom scan.</p>
