I am writing a chapter on Mood disorders for a book entitled " an introduction to abnormal psychology". My chapter is almost finished and the editor approved with minor suggestions. But I find it pale as I couldn't provide neuroimages of MDD. I could see open access articles where images are present but I can't use them without the permission of the authors. I sent authors a request in Research Gate but no reply so far. Could anyone provide these along with citation format? The editor asks me to use MLA8 format.

I truly need your help. As this book is latest one, I want to incorporate latest images ( clear and colour-if permissible)

The book is for University and college students.

Commercial use or not I don't know yet.

Thank you so much in advance for your support.
