Confused my the meaning of this character's thought when he's facing against a monster 脳味噌の端っこの方で状況を整理する


**A character is facing against a monster, and I don't understand 1 part of
his thought here. Hope someone can explain to me its correct meaning.**

**脳味噌の端っこの方で状況を整理する (my guess: " I'm analyzing the situation/ my circumstance
with the edge of my brain " ???)**

More context : こちらの様子を窺い、隙あらば飛びかかる気配を見せる目の前の“ナニか”。

（左右は壁……。道幅は刀を振り回すにはちょっと狭い感じ。となれば、基本は突きで対応するしかない）

（逃げ道は後ろのみ……。うーん、大通りに戻った方が良いかな）

（けどこいつ……足の筋肉の付き方で、すばしっこそうなのが見てとれるんだよなぁ……広いところだと逆に不利か……？）

**相手からは片時も目を離さず、脳味噌の端っこの方で状況を整理する。**




It's not **with** but _**in** the corner of the brain_. It is similar to _at
the back of my mind_.

Basically, it says the character does the thinking without losing the focus on
the opponent.
