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
