Below you will find MATLAB code for 3D Visualization of a simulated brain signal. MATLAB Code t = linspace(0, 2*pi, 1000);  frequency = 1;  amplitude_cos = 1;  amplitude_sawtooth = 0.5;  brain_signal = amplitude_cos * cos(2*pi*frequency*t) + amplitude_sawtooth * sawtooth(2*pi*frequency*t); figure; plot(t, brain_signal, ‘LineWidth’, 2); title(‘Simulated Brain Signal’); xlabel(‘Time (s)’); ylabel(‘Amplitude’); grid on; figure; subplot(2, 1,…
