You are perfectly right

and i think you will not correct homework either but iīll try nevertheless. could you just say if it is right what i found out?that would be a great help.
my solution is:
1) "S: (Aux
Are) +
(NP you) + (VP interested (PP in (NP the (AP human) brain))))?"
2) "S:(Aux
Would) + (NP
you) + (VP
like to conduct(does it belong together as one verb?) (NP
research (PP
into (NP
the workings) (PP
of (NP
the brain))))) [Conj
and] (VP

3) S:(NP
The Masterīs programme (PP in (AP Cognitive Neuroscience))) + (VP

?what is "closely involving" in this sentence?a whole VP? (AP

involving (NP

Comp./subclause?:
who (VP

4) "S:(NP

all(is "all" a noun phrase?) (PP

5) "S: (NP
