Functions

cell_assembly_detection

Cell assembly detection via PCA on binned spike matrix (Lopes-dos-Santos et al. 2013). Returns list of assemblies (each a list of neuron indices).

functional_connectivity

Functional connectivity matrix from peak cross-correlation. Returns n×n matrix (flat, row-major) where (i,j) = max |cc| between neurons i and j.

symmetric_eigen 🔒

Descending eigenvalues and sign-canonicalised eigenvectors of a symmetric matrix a (row-major n × n) via nalgebra’s symmetric eigensolver (tridiagonalisation + implicit QR — LAPACK-grade, replacing a hand-rolled Jacobi sweep). Eigenvectors are returned row-major (vecs[row * n + col]), column i paired with eigenvalue i, each sign-fixed so its largest-magnitude entry is positive.

synfire_chain_detection

Synfire chain detection via cross-correlation peak ordering (Abeles 1991). Returns list of chains (ordered neuron indices).

unitary_events

Unitary event analysis (Gruen et al. 2002). Detects bins where coincident spikes exceed Poisson chance. Returns list of significant bin indices.
