Drosophila larval mushroom body

graspologic.datasets.load_drosophila_left(return_labels=False)[source]

Load the left Drosophila larva mushroom body connectome

The mushroom body is a learning and memory center in the fly brain which is involved in sensory integration and processing. This connectome was observed by electron microscopy and then individial neurons were reconstructed; synaptic partnerships between these neurons became the edges of the graph.

Parameters:
return_labelsbool, optional (default=False)

whether to have a second return value which is an array of cell type labels for each node in the adjacency matrix

Returns:
graphnp.ndarray

Adjacency matrix of the connectome

labelsnp.ndarray

Only returned if return_labels is true. Array of string labels for each cell (vertex)

Parameters:

return_labels (bool) --

Return type:

ndarray | Tuple[ndarray, ndarray]

Duke mouse whole-brain connectomes

graspologic.datasets.load_mice()[source]

Load connectomes of mice from distinct genotypes.

Dataset of 32 mouse connectomes derived from whole-brain diffusion magnetic resonance imaging of four distinct mouse genotypes: BTBR T+ Itpr3tf/J (BTBR), C57BL/6J(B6), CAST/EiJ (CAST), and DBA/2J (DBA2). For each strain, connectomes were generated from eight age-matched mice (N = 8 per strain), with a sex distribution of four males and four females. Each connectome was parcellated using asymmetric Waxholm Space, yielding a vertex set with a total of 332 regions of interest (ROIs) symmetrically distributed across the left and right hemispheres. Within a given hemisphere, there are seven superstructures consisting up multiple ROIs, resulting in a total of 14 distinct communities in each connectome.

Returns:
dataBunch

Dictionary-like object, with the following attributes.

graphslist of np.ndarray

List of adjacency matrices of the connectome

labelsnp.ndarray

Array of string labels for each mouse (subject)

atlaspd.DataFrame

DataFrame of information for each ROI

blockspd.DataFrame

DataFrame of block assignments for each ROI

featurespd.DataFrame

DataFrame of anatomical features for each ROI in each connectome

participantspd.DataFrame

DataFrame of subject IDs and genotypes for each connectome

metaDictionary

Dictionary with meta information about the dataset (n_subjects and n_vertices)

Return type:

Bunch
