Subplot Titles left justified

I want to create some left justified subplot title as in this picture:

I know how to get subplot titles:

subplot(2,2,1);

title('A No Depression')

But moving the title all the way to the corner then adding some descriptors of a different font size are confusing me a bit. Any help? Thanks!

Prior to Matlab r2020b

1. Set the title's units to Normalize
2. Move the title leftward
3. Set the title's HorizontalAlignment to Left.

figure()
axes()
ttl = title('Input firing rates');
ttl.Units = 'Normalize'; 
ttl.Position(1) = 0; % use negative values (ie, -0.1) to move further left
ttl.HorizontalAlignment = 'left';  

Matlab r2020b or later

Set the TitleHorizontalAlignment propery of the axes. See more info in this Community Highlight.

figure()
ax = axes();
title('Input firing rates');
ax.TitleHorizontalAlignment = 'left';
