Tripartite synaptic structure
|
Glia (reuptake of neurotransmitter)
Presynaptic (synaptopores for releasing neurotransmitter) Postsynaptic |
|
Axo* communication
|
Axodendritic
Axosomatic Axoaxonic |
|
Loewi's experiment
|
Electrical stimulation -> Vagus nerve -> Heart 1 -> Heart 2 (bathed in same solution).
Stimulate Heart 1 and Heart 2 starts beating, indicating chemical communication |
|
Why chemical communication?
|
Modulatory activity that is neither excitatory nor inhibitory per se
|
|
Ionotropic receptors
|
Made up of varying numbers of transmembrane subunits
Upon ligand binding ion channel opens allowing ions to enter and / or exit the cell Tight coupling of binding / unbinding allows for fast neuronal responding Can lead to excitation / inhibition depending on the ligand |
