Functional connectivity predicts age group

This example compares different kinds of functional connectivity: correlation, partial correlation, and tangent space embedding. The resulting connectivity coefficients are then used to classify participants by age group; i.e., children or adults.

This is a small example to showcase Nilearn features; see Dadi et al.[1] for a careful study.

Load brain development fMRI dataset

To save computation time, we will use only a subset of subjects from the fetch_development_fmri dataset.

from nilearn.datasets import fetch_atlas_msdl, fetch_development_fmri

development_dataset = fetch_development_fmri(n_subjects=60)

[fetch_development_fmri] Dataset directory found: /home/runner/work/nilearn/nilearn/nilearn_data/development_fmri

Load Multi-Subject Dictionary Learning (MSDL) atlas and extract time series

We use probabilistic regions of interest (ROIs) defined using the fetch_atlas_msdl atlas.

We then use the MultiNiftiMapsMasker object to extract time series from the pre-defined ROIs for each subject. We could instead do this iteratively for each subject using NiftiMapsMasker objects, but MultiNiftiMapsMasker allows to extract time series for all subjects in a single step.

from nilearn.maskers import MultiNiftiMapsMasker

msdl_data = fetch_atlas_msdl()

masker = MultiNiftiMapsMasker(
    msdl_data.maps,
    resampling_target="data",
    t_r=development_dataset.t_r,
    detrend=True,
    low_pass=0.1,
    high_pass=0.01,
    memory="nilearn_cache",
    memory_level=1,
    standardize_confounds=True,
    standardize="zscore_sample",
    verbose=1,
)
masked_data = masker.fit_transform(
    development_dataset.func, confounds=development_dataset.confounds
)

What kind of connectivity is most powerful for classification?

We will next define connectivity matrices using ConnectivityMeasure so that we can use each matrix as features in our classification analysis. Since our goal is to compare different kinds of connectivity, we will define three different kinds of connectivity matrices, (i.e., “correlation”, “partial correlation”, “tangent”) using the kind parameter.

To do this, we will use a scikit-learn Pipeline to combine the connectivity measure and the classifier into a single object. Specifically, we will create a composite estimator with ConnectivityMeasure and sklearn.model_selection.GridSearchCV to perform a grid search over the C regularization parameter for our classifier, a sklearn.svm.LinearSVC.

# prepare the classification pipeline
from sklearn.dummy import DummyClassifier
from sklearn.model_selection import GridSearchCV
from sklearn.pipeline import Pipeline
from sklearn.svm import LinearSVC

from nilearn.connectome import ConnectivityMeasure

kinds = ["correlation", "partial correlation", "tangent"]

pipe = Pipeline(
    [
        (
            "connectivity",
            ConnectivityMeasure(
                vectorize=True,
            ),
        ),
        (
            "classifier",
            GridSearchCV(
                LinearSVC(dual=True, random_state=0),
                {"C": [0.1, 1.0, 10.0]},
                cv=5,
            ),
        ),
    ]
)

param_grid = [
    {"classifier": [DummyClassifier(strategy="most_frequent")]},
    {"connectivity__kind": kinds},
]

Rather than evaluating on the whole sample of 60 subjects, we want to cross-validate our model. We can directly pass the Pipeline object we defined above to a cross-validation estimator.

Given the unbalanced sampling of age groups in fetch_development_fmri, we will use stratified cross-validation to preserve the proportion of each age group in the training and testing sets. We will define 30 random, stratified splits of the subjects into training and testing sets, using sklearn.model_selection.StratifiedShuffleSplit.

from sklearn.model_selection import StratifiedShuffleSplit
from sklearn.preprocessing import LabelEncoder

groups = development_dataset.phenotypic["Child_Adult"].to_list()
classes = LabelEncoder().fit_transform(groups)

cv = StratifiedShuffleSplit(n_splits=30, random_state=0, test_size=10)
gs = GridSearchCV(
    pipe,
    param_grid,
    scoring="accuracy",
    cv=cv,
    refit=False,
    n_jobs=2,
)
gs.fit(masked_data, classes)
mean_scores = gs.cv_results_["mean_test_score"]
scores_std = gs.cv_results_["std_test_score"]

Finally, we display the classification accuracy results:

import matplotlib.pyplot as plt

plt.figure(figsize=(6, 4), constrained_layout=True)

positions = [0.1, 0.2, 0.3, 0.4]
plt.barh(positions, mean_scores, align="center", height=0.05, xerr=scores_std)
yticks = ["dummy", *list(gs.cv_results_["param_connectivity__kind"].data[1:])]
yticks = [t.replace(" ", "\n") for t in yticks]
plt.yticks(positions, yticks)
plt.xlabel("Classification accuracy")
plt.gca().grid(True)
plt.gca().set_axisbelow(True)

This is a small example to showcase Nilearn features. In practice, such comparisons need to be performed on much larger cohorts and replicated across several datasets. Dadi et al.[1] showed that across many cohorts and clinical questions, tangent functional connectivity should be preferred.

plt.show()
