The brain has billions of nerve pathways.
New pathways form during development.
During learning the pathways are more likely to trigger impaulses, so skills can be learnt by experiences.
memory is the store and retrieval of information.
memory can be long term, or short term
human remeber better if they see a pattern in information
humans have complex behaviour
living things respond to stimulus to help them servive
simple reflexs travel though reflex arcs
animals with simple behaviour can not respond to new situations.
neurons carry electrical inpaulses
neurons are seperated by synapes
some drugs have an affect on the transmission of inpaulses across the synapes.
stimulus are detected by receptor cells
nerve impaulses are carried along a sensory nerve to the CNS
the CNS is made up of the brain and the spinal cord which conrol the bodies responses
the effector carries out the response
