| Hi,
|

| (I do not know what this is) removed still
| concious or does he just react reflexly?

Frontal lobe 'removel' would leave the
person imobile. It's where the primary motor
cortex is.

Prefrontal cortex is a better candidate with
respect to your Q.

It's 'removal' significantly degrades 'con-
sciousness'. [Look up "Phineas Gage".]

But 'consciousness' derives in =global=
nervous system function, and any leision
['removal or disconnection], anywhere,
degrades it.

| Supplemental:
|
| Is there a part of our brain that when removed
| abolishes "conciousness".

No.

Unless it's the 'last' such thing that can be
'removed'.

| By "concious" I mean the subjective experience
| of being aware of ouselves and our environment,
| not just "being awake".
