What is a stimulus?
A stimulus is a change in an organism's environment. Animals respond to stimuli in order to keep themselves in suitable conditions for survival.

What type of neuron carries impulses from the central nervous system to an effector such as a muscle?
MOTOR neurons carries impulses from the CNS to effectors.
2 of 16
What is the name of the gap between two neurons?
Synapse
3 of 16
What is the name of the long fibre attached to the cell body in a motor neuron?
An axon
4 of 16
What is a reflex action?
A reflex action is a fast, automatic, involuntary response to a stimulus.
5 of 16
What is the name given to the type of action when the final response has no direct connection to the stimulus?
Conditioned reflex action

What develop in the human brain allows learning from experience e.g language?
Neuron pathways
7 of 16
Which part of the brain is most concerned with intelligence and memory?
The cerebral cortex of the brain
8 of 16
Name the technique that produces images of cross sections of the brain
MRI scans

What is memory?
Memory is the ability to store and retrieve information. It can be divided into short term memory (stores info for a limited amount of time) or long term memory (stores an unlimited amount of info)

How do drugs like Prozac and Ecstasy affect the nervous system?
They affect the passage of an impulse across a synapse.
11 of 16
What is learned behaviour?
Learned behaviour is responses to a stimuli which an organism develops because of experience. It can change behaviour if the environment changes. It aids survival.
12 of 16
What methods can you use to help map the brain?
Brain damage, electrical stimulation and MRI Brain scans
13 of 16
Explain the brain damage method to help map the brain
Study patient with brain damage to learn which parts of the brain are responsible for different jobs.
14 of 16
Explain the electrical stimulation method to help map the brain
Probe with a weak electrical current to touch different parts of the brain and asking the patient what they experience.
15 of 16
Explain the MRI Brain scans method to help map the brain
MRI patients perform a task while being scanned allowing scientists to identify which areas of the brain are active in each task.
