How humans learn
· When we learn something new our brain develops a new pathway
so that it stays in our mind and we can go back and do it again. By
repeating it, the pathway becomes stronger and it makes it easier to
do what we have just done. We have millions of pathways and every
time we learn we gain a new pathway and we get smarter, this is
learning. Sometimes repetition can be used to learn new skills, like
riding a bike, you cant ride one at first but the more you practice the
better you become.
· Gymnasts have the same muscles as us but have learnt to do the
stuff they do by repeating it making them more flexible and
· In 1799 a feral child known as victor, was born and left in the wild for
12 years and by that age he couldn't learn to speak, he was without
the ability to learn, this shows that you stop learning at a certain age
for certain things.…read more

The brain and memory
· The brain contains the cerebral cortex, this is responsible for high
level learning, like learning a new language, or speech itself.
· Scientists conducted many experiments to see what parts of the
brain work, like during brain damage, electrical stimulation and MRI
brain scans. There are also two types of memory, short term and
long term, short term can last for about 30 seconds, for example,
when you ring someone using a number, you usually forget it by the
end of the call. Long term is handy because it can stay with you your
whole life and it will stay with you. Alzheimers is a disease where
you lose short term memory but keep your child hood memories,
whereas with brain damage you can forget about your life but your
short term memory works fine, this shows the difference and how
the brain works in different situations.…read more

How drugs affect the nervous
· Me drugs and toxins affect how the nervous
system works. Sometimes they do the opposite
of each other, for example
· curare stops the impulse from passing to the
synapse and cause the person to stop moving
(paralysis) and can stop them breathing
· Strychnine causes the impulse to continuously
go through the synapse causing the person to
spas out and stop breathing.…read more
