Audit review

Core elements of the candidate solution match the paper’s modeling setup (generative mean-field with adaptation, elliptical exponentially decaying kernels, and an outer-loop grid-search in amplitude–period space using KL metrics) and add the missing mathematical guarantees (existence on compacta, continuity of the outer objective, explicit gradients). The paper defines the log-likelihood as a negative squared error (their Eq. (9)) and then writes a gradient with an extra leading minus sign (their Eq. (10)); by direct differentiation the sign should be positive, as the candidate notes and derives correctly, so the paper’s derivative expression is inconsistent with its own likelihood definition . The structural kernel parameterization and the derivative with respect to λ agree with the candidate’s derivations (paper’s Eqs. (13)–(15)) . The adaptation dynamics and the neuromodulation ansatz used by the paper match the candidate’s treatment and yield the candidate’s partials with respect to I_ext,0 and b_0 (paper’s Eqs. (4)–(5), (19)–(20)) . For the outer loop, the paper indeed uses grid-search and KL comparisons of frequency, velocity, direction and their joint 3D distribution, though the text contains inconsistent reported optima across different figures; the candidate’s proposal to formalize J(A,T) as a sum of KLs with pseudocount smoothing, and to compare J(0,T) against J(A*,T*), fills in analysis details absent in the paper . Overall, the paper is methodologically sound but omits key assumptions and contains at least one sign error; the candidate solution is correct (under explicit compactness and smoothness hypotheses) and more rigorous.

Referee report (LaTeX)

\textbf{Recommendation:} minor revisions

\textbf{Journal Tier:} specialist/solid

\textbf{Justification:}

The manuscript presents a coherent and useful two-step inference framework for mesoscale cortical models, anchored in plausible anatomical priors and validated against rich wave statistics. Its main limitations are a derivation sign error in the gradient and the absence of explicit assumptions and tests that would strengthen correctness and reproducibility. These issues are easy to remedy and do not undermine the central contributions; with minor revisions, the paper will be a solid reference for data-constrained slow-wave modeling.
