N.B. The figures associated with these notes have been taken from a variety of sources including:

Physiology (Berne & Levy); Principles of Neural Science (Kandel, Schwartz & Jessell); Essentials of Neurophysiology (Somjen); Review of Medical Physiology (Ganong); Medical Physiology (Guyton); Medical Physiology (Rhoades & Tanner) among others. They are reproduced here for the instruction of students for whom these texts are recommended reading. Some illustrations also come from various journal articles.  The use of these figures in this context has no financial implications for either the students or the lecturer involved. They should not be reproduced from this site. [Updated: 26 February, 2002].
