The prompt
Refine the EXISTING model shown in the reference image. Do not rebuild or remove the existing Y-junction, two inlet ports, main channel, central culture chamber, or outlet. Complete the neural organ-on-chip architecture by adding: 1. A clearly visible MEA electrode array underneath the central neural culture chamber, centered within the existing substrate. 2. Inside the central culture chamber, create two adjacent neural culture compartments separated by a narrow barrier containing multiple parallel microtunnels. 3. The microtunnels must be narrow, parallel, symmetric, and clearly smaller than the main fluidic channels. 4. Keep the existing two-inlet Y-junction gradient generator and single outlet unchanged. 5. Keep the PDMS microfluidic layer above the rigid glass/silicon MEA substrate. 6. Ensure the MEA electrodes are positioned directly beneath the neural culture region. Use millimeters and reasonable editable dimensions where unspecified. Do not add decorative geometry, pumps, tubing, cells, or electronics. Keep the model parametric and editable. Preserve the existing successful geometry. Only add the missing MEA electrode array, neural compartments, and microtunnels.
