Dendrite structure
... (Ostapoff et al. 1994). These descriptors are not readily applicable to stellate neurons in other areas of the brain. In some neurons, dendrites radiate in arbitrary directions from the cell body but are restricted to a planar region. This type of laminar radiation (see Table 1.2) is seen in horizon ...

In its normal state, the ions have a small negative charge called resting potential. -This negative balance can be easily upset, however. When the cell becomes excited, it triggers the action potential, which reverses the charge and cause ...
