Document Summary

To control behaviour information has to be passed down amongst nerve cells. There is an electrochemical mechanism at synapse. The synapse is a functional connection between neurons. Neurotransmitter released from presynaptic terminal and it binds to postsynaptic receptors. Inside the cell there are lots of negative-proteins called anions and k+, there is also some na+ and cl- A membrane potential is the difference in distribution of ions (charged atoms) inside and outside the cell. Outside the cell there are lots of na+ and cl- and only some k+ Therefore higher concentration of na+ outside the cell and higher concentration of k+ inside the cell. Nacl is the major ion (electrolytes) to keep cells working. The ion imbalance across the cell membrane results in a difference bw electrical charges bw the inside and.
