 Lec1	"This task belongs to a battery of 8 different localizers that tap on a wide array of cognitive functions provided to us by the `Labex Cortex group <https://labex-cortex.universite-lyon.fr/>`__ at the University of Lyon. This task, described in (`Saignavong et al., 2017 <https://doi.org/10.1142/S0129065717500010>`__), was originally used to test whether brain activity can be detected in single trials with intra-cerebral EEG-fMRI recordings. During the task, participants were presented with three vertically-arranged lines, indicated by the presence of two ""+"" symbols at both sides, and empty space between them. For each row, a different type of verbal stimuli was presented, and the participant was instructed to make a decision depending on the type of stimuli. The top row presented words, and the decision was an animacy decision (""Is it a living entity?""). The middle row presented pseudowords, and the decision was whether the pseudoword had one or two syllables. Finally, the bottom row presented consonant strings, and participants were instructed to answer if the string was all-uppercase or all-lowercase. First option was selected by pressing with the index finger on the response box whereas second option was given with the middle finger. The trials were presented in blocks, and each block contained a sequence of 5 stimuli for each of the three conditions. The order of this conditions inside each block was randomized across blocks, but fixed for all participants. The ""+"" symbols for the row corresponding to the next condition turned white to indicate which condition was next. There were two runs with 6 blocks each, each block comprising 15 trials, which were presented for 2000 ms, with an inter-stimulus interval of 500 ms."

 MVEB	"This task belongs to a battery of 8 different localizers that tap on a wide array of cognitive functions provided to us by the `Labex Cortex group <https://labex-cortex.universite-lyon.fr/>`__ at the University of Lyon. This task, described in (`Hamamé et al., 2012 <https://doi.org/10.1016/j.neuroimage.2011.07.087>`__), aims to assess **verbal working memory**. In this case, the participants were presented with a string of 6 characters, from where two, four or six of them can be letters (the rest are ""#"" symbols). After the string disappears, a single letter appears in screen. The participant had then to indicate if this single letter was part of the previously presented string. This was indicated by the participant with a 5-button response box, with one button for ""yes"" (index finger) and another for ""no"" (middle finger). The cognitive load was manipulated with the number of letters, and one condition was included where all the letters of the initial string would be the same one. Each trial commenced with the presentation of a 1500 ms fixation cross, followed by the array of characters (probe) for 1500 ms. After an intermediate period of 3000 ms, and the cue character was presented for 1500 ms. 36 trials were presented in each run. Data were acquired in two separated runs."

 MVIS	"This task belongs to a battery of 8 different localizers that tap on a wide array of cognitive functions provided to us by the `Labex Cortex group <https://labex-cortex.universite-lyon.fr/>`__ at the University of Lyon. This task, described in (`Hamamé et al., 2012 <https://doi.org/10.1016/j.neuroimage.2011.07.087>`__), and whose name stands for **visuo-spatial working memory** task, consists on a series of events in which the participant will be presented with a 4x4 grid in which two, four or six dots will appear at different positions, after that, the grid would become empty and finally a single dot would appear on it. The participant had then to indicate if this single dot was in the same position than any of the previously presented ones. This was indicated by the participant with a 5-button response box, with one button for ""yes"" (index finger) and another for ""no"" (middle finger). The cognitive load was manipulated with the number of dots, and one condition was included where one of the dots would be highlighted, signifying that was the only position to retain. Each trial commenced with the presentation of a 1500 ms fixation cross, followed by the array of dots (probe) for 1500 ms. The empty grid was presented for 3000ms, and the cue dot was presented for 1500 ms. 36 trials were presented on each run. The data were acquired in two runs."

-Moto	This task belongs to a battery of 8 different localizers that tap on a wide array of cognitive functions provided to us by the `Labex Cortex group <https://labex-cortex.universite-lyon.fr/>`__ at the University of Lyon. This task is a basic **motor localizer** for several body parts. The participants are presented with three small gray squares over a black background image. At the beginning of each block, a text prompt will appear on screen to indicate the body part that will be moved next. Afterwards, the left and right squares will turn white to indicate movement of the corresponding part. For example, for the hands condition, the participant is required to perform a small movement of the left hand when the left square turns white, and likewise for the right hand. Ten movements were prompted for each block, five for the right body part and five for the left, consecutively for each direction and always in the same order. There were two distinct blocks for each body part. For each trial, the white square was presented during 1000 ms, with 1500 ms between trials, for a total duration of 25 s per block, with a total of 12 blocks. Data were acquired in two separated runs.

For example, in the hand condition, participants were required to perform a small movement of the left hand when the left square turned white, and likewise for the right hand. Each block prompted 20 movements, 10 for each side, presented consecutively and in the same order. Two blocks were dedicated to each body part in every run. During each trial, the white squares were presented during 1000 ms, with a 1500 ms interval between trials, resulting in a duration of 25 seconds per block. Each run consisted of 12 blocks, and data were collected over two separate runs.

 MCSE	"This task belongs to a battery of 8 different localizers that tap on a wide array of cognitive functions provided to us by the `Labex Cortex group <https://labex-cortex.universite-lyon.fr/>`__ at the University of Lyon. This task described in (`Ossandón et al., 2012 <https://doi.org/10.1523/JNEUROSCI.6048-11.2012>`__) was originally used to study whether visual search processes of a salient target can be thought as a purely bottom-up process, or if it requires action from top-down attentional processes. The task consisted in the presentation of an array of 35 ""L"" letters, rotated at different angles, together with a target ""T"" letter (total 36 stimuli in each trial). Subjects were instructed to search for the target and indicate whether it was on the left or right side of the grid, by pressing respectively with the index or middle finger on a 5-button response box. There were two conditions: high-salience (the target is gray while the other stimuli is black) and low-salience (all stimuli are gray). The two conditions were presented alternatively in blocks, with 6 blocks of 10 trials each. Each trial was presented for 3 s with an inter-stimulus interval of 1 s. There was also a 20 s fixation cross between blocks. Data were acquired in two separated runs."

 Audio	This task, originally described in (`Santoro et al., 2017 <https://doi.org/10.1073/pnas.1617622114>`__), is an auditory localizer. During each run, the participants were presented with sounds from different categories, and were instructed to press a button with the index finger whenever two consecutive sounds were identical. From a group of 288 sounds, divided into 6 different categories, 4 sets were created. Each set contained 72 sounds of each of the categories, and each one was present only in one of the sets. Furthermore, each set was pre-randomized in 3 different orders, and the same sequences were used for all participants. On top of the 72 sounds, each run also included 5 silences and 5 repeated sounds from the original 72. In total, each run consisted of 82 trials of 2 seconds each. It is important to note that the data for this task was acquired using an interrupted acquisition sequence, to minimize the effect that scanner noise can have in the auditory processing targeted by the experiment. To this end, the inter-stimulus interval was programmed in a sequence of 4, 4, and 6 seconds, meaning that the interval between stimuli would be 4s for the first trial, 4s for the second, 6s for the third, and then the sequence repeats until the end of the run. The variability of the ISI and the silence trials avoided stimulus' presentation to be predictable in time. :raw-html:`<br />` **Note:** We used the MagnaCoil (Magnacoustics) audio device for all subjects except for *subject-08*, for whom we employed Optoacoustics.

 Attention	This task is a part of a battery of several tasks coming from the `experiment factory <https://github.com/expfactory/expfactory-experiments>`__ published in (`Eisenberg et al., 2017 <https://doi.org/10.1016/j.brat.2017.09.014>`__) and presented using `expfactory-python <https://github.com/expfactory/expfactory-python>`__ package. The battery was used to capture several aspects of self-regulation, including behavioral inhibition, decision making and planning abilities, among others. The adjustments concerned the translation to all written stimuli and instructions into french, as well as fixing a total time limit for experimentsthat allowed the participants their own pace for responding. All these modifications were done with extreme care of not altering the psychological state that the original tasks were designed to capture during scanning. :raw-html:`<br />` The Attention is a version of the classical flanker task (`Eriksen and Eriksen, 1974 <https://doi.org/10.3758/BF03203267>`__), where the participant has to judge the direction the target flanker (an arrow) is pointing to (left/right). The target flanker is surrounded by other 4 flankers that can be congruent or incongruent with the target one, thus capturing selective attention and inhibitory processes. Two different buttons (index and middle fingers' button, respectively) were assigned to left/right responses, and the participant had to indicate the direction of the central arrow from an horizontal group of 5 arrows. In each trial, one or two positional cues were presented above and below the center of the screen. When one cue was given, the flankers would appear centered around it, whereas when two cues where presented, the flankers would appear centered around one of them. The four flankers surrounding the target would always point to the same direction, and can be congruent or incongruent with the direction the target flanker is facing. The task was acquired in two runs, within the same session as other tasks from the battery and using different phase-encoding directions. :raw-html:`<br />` For the original version of this task, the authors provide a `simulator <https://expfactory.github.io/v1/attention_network_task.html>`__, which contains the original design.
