localizer first level dataset

Access

See nilearn.datasets.fetch_localizer_first_level.

Notes

Single subject dataset from the “Neurospin Localizer”. It is a fast event related design: during 5 minutes, 80 events of the following types are presented :

• ‘audio_computation’,

• ‘audio_left_hand_button_press’,

• ‘audio_right_hand_button_press’,

• ‘horizontal_checkerboard’,

• ‘sentence_listening’,

• ‘sentence_reading’,

• ‘vertical_checkerboard’,

• ‘visual_computation’,

• ‘visual_left_hand_button_press’,

• ‘visual_right_hand_button_press’

The data was preprocessed and is in MNI305 space.

The protocol described is the so-called “ARCHI Standard” functional localizer task.

For details on the task, please see Pinel et al.[1].
