Q

What is hemispheric lateralisation?

A

The assumption that the 2 hemispheres of the brain function differently

17
Q

What is a strength of lateralisation?

A

Lateralisation in the connected brain - when people with connected brains were asked to look at an image as a whole, the RH was more active and when looking at the details, the LH was more active

18
Q

What is a weakness of lateralisation?

A

One brain - there is no dominant side to the brain

19
Q

What does the visual centre do?

A

Process visual information

20
Q

What does the auditory centre do?

A

Process audial information

21
Q

What does the motor cortex do?

A

Controls conscious movement

22
Q

What does the somatosensory cortex do?

A

Detects sensory events like touch

23
Q

What is the nervous system?

A

Controls the CNS and the PNS through electrical signals

24
Q

What is the CNS?

A

(Central nervous system) consists of the brain and the spinal cord, origin of all complex commands and decisions

25
Q

What is the PNS?

A

(Peripheral nervous system) Sends information to the CNS from the outside world, transmits messages from the CNS to muscles and glands

26
Q

What is the SNS?

A

(Somatic nervous system) Transmits information from receptor cells in the sense organs to the CNS, receives information from the CNS that directs muscles to act

27
Q

What is the ANS?

A

(Autonomic nervous system) Transmits information to and form internal bodily organs, operates involuntarily, 2 main divisions : sympathetic and parasympathetic nervous system

28
Q

What is a neuron?

A

Nerve cells that process and transmit messages through electrical and chemical signals

29
Q

What are sensory neurons?

A

Carry messages from the PNS to the CNS, have long dendrites and short axons

30
Q

What are relay neurons?

A

Connect the sensory neurons to the motor or other relay neurons, short dendrites and short axons

31
Q

What are motor neurons?

A

Connect the CNS to effectors such as muscles and glands, short dendrites and long axons
