Commumication within and between neurones

neurones extend over long distances with signals going from one part to another

trigger -> release of energy -> signal= AP

~-70mV

movement of ions from high areas of concentration to low concentration

attraction & repulsion

something that moves specific ions

specifically codes for info via frequency

AP is adjacent part of axon which needs chemical transmission between neurones

recipient neurones need depolarising as the signal cant jump

excitatory, same as depolarisation, opens cation channel, EPSPs
