What is this unit about?
Every day we use our brain in so many different ways
that it is just impossible to think of them all. Just walking
or making a cup of tea requires a lot of brain power. And
we don't just do all of these things instinctually, these
are learned behaviours. It's these learned behaviours
that give some animals a survival advantage.
Response An action that is triggered by a stimulus
Stimulus A change in an organism that triggers a response
Behaviour A specific response of a certain organism to a
Simple Reflex An involuntary
response to a stimulus
Involuntary A response that is
Complex behaviour is better
because it allows certain animals
to adapt if their environment
Describe 2 reflexes in:
Moving your hand away from a hot surface
These reflexes help us to survive because the first reflex helps us to
minimise the injuries we receive and the pupil reflex allows us to
see, making sure that our eyes are not damaged if the
surroundings are too bright.
Not breathing when underwater
These simple reflexes help a baby to survive
because grasping means that when they are
picked up, they are less likely to be dropped because they are
holding on and the latter helps because it means that a baby will
not take in water when for example, swimming.
What does a neuroscientist do? Do all
neuroscientists study the same things?
A neuroscientist that looks at someone's brain,
specifically, the nervous system.
Not all neuroscientists study the same things, for
example there is the cellular neuroscientist who looks at
the brain on a cellular level and there is the
computational neuroscientist who focuses of the
information processing properties
and structure of the nervous system.
