Adding and combining signals to form one big one

-Spacial summation and temporal summation (time)

Wider and myelinated

-conduction in interneurons usually passive and decremental

-been found to actively conduct APs away from site of generation in either direction

- Dendritic spines change very rapidly to neural stimulation

-Dendritic spines compartmentalize denderite - keep postsynaptic chemical changes restricted to immediate area in synapse

-Usually responding to diff receptors but when other axon coming into play, will respond to those signals as well.

-axoaxonal contact: presynaptic inhibition and facilitation

-Site of release at some distance from site of reception

-Varicosities along axon and widely dispersed to surrounding targets

-string-of-beads

-small: made in cytoplasm of terminal button, packaged into vesicles by golgi complex

-Big: Created by ribosomes in cytoplasm of cell body ->packaged into vesicles by golgi complex and transported microtubules

1. Allow small molecules to pass through passively, very fast comm

2. Permit comm in either direction
