## Overview

### Project name

What does the amygdala do? A dense fMRI study in three individuals

### Dataset description

Dense complex-valued partial brain BOLD of passive audiovisual movie presentations

### Year(s) that the project ran

Data was acquired at the Caltech Brain Imaging Center between February and June 2022

### Brief overview of the tasks in the experiment

Slab-selective, short-TR BOLD fMRI was acquired in three healthy individuals while they watched rich audiovisual stimuli drawn from movies, TV series and movie trailers. In total, approximately 15 hours of complex-valued BOLD fMRI data was acquired per individual, with associated physiological recordings and pupilometry.

### Independent variables

Passive movie watching with audio contains a rich set of independent variables ranging from low-level visual features to social and emotional features.

### Dependent variables

Complex-valued (magnitude and phase) T2*-weighted multislice EPI
4-channel ECG waveforms synchronized to fMRI scanning
Phase derived respiratory waveform estimates synchronized to fMRI scanning
Pupilometry during movie watching synchronized to fMRI scanning
High resolution and high CNR individual T1w and T2w structural templates

### Control variables

All individuals watched identical audiovisual stimuli with individually calibrated audio presentation

## Methods

### Subjects

The participants in this experiment were three adult volunteers drawn from the laboratory of Ralph Adolphs
at the California Institute of Technology. All recruitment and experiments were performed under a protocol approved
by the Caltech IRB (IR).

### Apparatus

All MRI data was acquired using a 3T Siemens Prisma.Fit equipped with a 32 channel head array.

### Experimental location

All MRI data was acquired at the Caltech Brain Imaging Center located at
B102 Broad 114-96
360 South Wilson Ave,
Pasadena, CA 91125
USA
