The way I am using to collect many sub-figures in one figure is like that:

MWE:

\begin{figure}[b!]
\begin{center}
$%
\begin{array}[t]{cc}
\text{\includegraphics{PHDImages/Chapitre2/gamma-variate.eps}} & \text{%
\includegraphics{PHDImages/Chapitre2/gamma-variate.eps}} \\ 
\text{(a)} & \text{(b)} \\ 
\text{\includegraphics{PHDImages/Chapitre2/gamma-variate.eps}} & \text{%
\includegraphics{PHDImages/Chapitre2/gamma-variate.eps}} \\ 
\text{(c)} & \text{(d)}%
\end{array}%
$%
\end{center}
\caption{title}
\label{fig:FIGURE2.8}
\end{figure}

and the result:

but what I want actually is to put sub-figures captions in the top (BOLD left-handed) like in the following image:

how can I do that?

    Welcome to TEX-SE! Please always provide a complete example that starts with \documentclass and ends with \end{document}. Otherwise we do not know which packages you are using. Also you may be interested in this post. – user121799 Jul 4 at 18:28

I wouldn't use an array environment to position the graphs. Instead, I would load the subcaption package and use its machinery to arrange the graphs and associated captions.

enter image description here

\documentclass[demo]{article} % omit 'demo' option in real doc.
\usepackage[T1]{fontenc}
\usepackage{subcaption,graphicx}
\captionsetup[subfigure]{skip=0.25\baselineskip,justification=raggedright,
              font={footnotesize,bf},labelsep=space,labelformat=simple}
\renewcommand\thesubfigure{\Alph{subfigure}}

\begin{document}
\begin{figure}
\begin{subfigure}[b]{0.475\textwidth}
\caption{flow\,=\,damped oscilator, CMRO2 coupled}  
\includegraphics[width=\textwidth]{PHDImages/Chapitre2/gamma-variate1.eps}
\end{subfigure}\hfill
\begin{subfigure}[b]{0.475\textwidth}
\caption{flow\,=\,gamma variate convolutions, CMRO2 coupled} 
\includegraphics[width=\textwidth]{PHDImages/Chapitre2/gamma-variate2.eps} 
\end{subfigure}

\begin{subfigure}[t]{0.475\textwidth}
\caption{\dots}  
\includegraphics[width=\textwidth]{PHDImages/Chapitre2/gamma-variate3.eps}
\end{subfigure}\hfill
\begin{subfigure}[t]{0.475\textwidth}
\caption{\dots}  
\includegraphics[width=\textwidth]{PHDImages/Chapitre2/gamma-variate4.eps} 
\end{subfigure}

\caption{title}
\label{fig:FIGURE2.8}
\end{figure}
\end{document}
