ITU Tier 1+ #28: Neuroscience (K_neuro)

Tier 1+ Pass-1.5 paper 28 of 45. ITU-derived neuroscience on neuron + synapse + circuit + network + behavior. Defines K_neuro = -log ρ_neuro as the operator-algebraic modular Hamiltonian on H_neuron ⊗ H_synapse ⊗ H_circuit ⊗ H_network ⊗ H_behavior. K_neuro inherits from K_QG via the CLPW 2023 type II crossed-product specialised to this scale. Numerical results.
