Synapses
site of communication
Electrical Synapses
Gap junctions - can travel straight over the synapse
Electrical Synapses allow
synchronization
Chemical Synapses
information passes chemically
synaptic cleft
space between pre-synaptic & post synaptic
excitatory
increases the probability of an action potential occurring in a postsynaptic cell
inhibitory
they decrease the likelihood that the neuron will fire an action potential
common neuro transmitters
acetycholine
gamme-aminobutyric acid
dopamine
serotonin
