“脑子”这个词在中文里用处不少，我们可以说一个人have brains“有脑子”，也就是说这个人有想法；我们也可以说一个人have not a brain in one’s head“没脑子”，那就是说这个人想法太简单、太单纯。还有一类人我们可以说他们“死脑子”或“死脑筋”，意思是说这类人思想不灵活，不肯接受新事物。在英文里，就叫ROM brain。

ROM brain refers to a person who refuses to accept input¹ and ideas from other people. It may also be someone who spews ideas and opinions but can't seem to accept input from the outside world.

“只读型大脑”指那些拒绝接受别人劝告或想法的人（相当于我们常说的“死脑筋”），也可以指四处发表见解却不肯接受外界信息的人。

This idea stems² from the computer term ROM (commonly known as read-only memory), a storage media where data cannot be modified, at least not very quickly or easily.

“死脑筋”之所以叫“ROM brain”是因为ROM在电脑术语中意为只读，存储在这一类别存储媒介的数据一般是无法修改的，至少不能快速或轻易被修改。

For example:

He is not willing to take in any new ideas. A ROM brain indeed.

他不愿意接受任何新思想，是个地道的“死脑筋”。
