Things to remember for behavioural neuroscience midterm ii: Glycolipids modified phospholipids, protective, receptor binding, recognition of self. Electrostatic pressure and force of diffusion: na+ 120 mv into cell (e and d both inside), k+ 20 mv outside cell (d outside, e inside), cl- 0mv (d inside, e outside) Sodium potassium pump 3na+ and 2k+, keeps concentrations the same. Epsp positively excite, due to opening of na+ channels. Ipsp negatively excite, due to opening of k+ channels. Psps decremental, rapid, do not travel far before dying out, graded response, passive. Spatial summation 3 possibilities, same time, different locations, add energies. Temporal summation 2 possibilities, same location, rapid succession. Action potential all or none response, non-decremental, active, longer lasting, slower. Relative refractory can be stimulated but with a bigger strength, allows us to see different light intensities etc. , action potentials leave trace of refractory periods. Rate of firing is correlated with stimulus intensity.
