can someone please explain to me the role of the CNS and the PNS in receiving sensations and initiating voluntary movement?

Revising for a upcoming SAC atm, quick question:

If asked whether split brain patients know what they saw in the left visual field, do i just state that they do know what they saw because they are able to use their left hand to locate/draw the object? So it is simply a matter of not being able to verbally state this?

Yes because the information is processed in the right side of each retina of each eye which goes to the occiptal lobe (visual cortex) in the right hemisphere of the brain. The right hemisphere is responsible for object identification and the language areas are mostly located in the left hemisphere of the brain only.

Hope this helped!

can someone please explain to me the role of the CNS and the PNS in receiving sensations and initiating voluntary movement?

Central Nervous system consists of the brain and spinal cord and transmits and receives messages from the PNS.

The Peripheral Nervous System carries messages to and from the CNS. In terms of initiating voluntary movement, the somatic nervous system (a subdivision of PNS) carries messages from sensory receptors in the body to the CNS & motor messages from the CNS to the skeletal muscles.

The ascending pathway is where the sensory information from the PNS travels up the spinal cord to the brain while the descending pathway is where motor messages from the brain travel down the spinal cord to the PNS. 

Hope this helped!

Got my first SAC on Tuesday regarding research methods and the nervous system (CNS and PNS). Hope it all goes well.

Good luck ! Go smash that !

Haha thanks!

Can someone please clarify for me: what brainwaves are present when we daydream? Is it alpha waves only or alpha and theta waves?
Also, the 'relaxed' state BEFORE stage 1 NREM (characterised by alpha waves) is still normal waking consciousness right? :/

Thanks

Hey:)
Does anyone know the amount ins minute thatw e spend ineach NREM stage aswell and REM.Different notes have different answerss
THANKSSS

REM
Rem: periods of Rem sleep gradually increase with each 60 minutes cycle of sleep with the first REM sleep period only going to for a couple of minutes, while the last period of REM sleep may go up to 1 hour.
NREM
stage 1: typically lasts for about 5 to 10 minutes
stage 2: 10 to 20 minutes
stage 3: lasts for about 10 minutes
stage 4: generally 20 minutes of this stage at the first cycle.
Its important to note that during our nights sleep the amount of time spent in slow wave sleep (stages3.4) gradually decreases.

Thank you so much:)))))))

Can anyone tell me what a extended response section of a sac could look like/ structured.
It's out of 15 marks, marked against a rubric and is on brain research methods. I'm pretty sure it's only on ethics.

I'm not sure if it's like section 3 vcaa, because teacher said you don't need to know research methods.

Does anyone's schools outsource there SAC's from a company called "QATS"?

Will we ever need to know how to identify the different types of brain waves just by looking at the image of the brain wave, also the EEG, EOG and EMG wave patterns for awake, different stages of NREM, REM sleep (Like given an image of the wave pattern then having to identify whether the individual is awake or asleep and if so NREM (which stage) or REM sleep)?

Psychology is going to be my worst subject, and I thought it was going to be my best. It is purely ROTE learning and I hate it. You have to memorise like 10 dot-points for things. I wish it was more conceptually based rather than ROTE.

Yup! was worth about 9-10 marks on my sac!
we had to identify the brain waves and what stage of sleep they were in (given EEG, EMG and EOG)
