Drosophila larval mushroom body

graspy.datasets.load_drosophila_left(return_labels=False)

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_labels : bool, 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:

graph : np.ndarray

Adjacency matrix of the connectome

labels : np.ndarray

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