Inhibitory Synapses

• So far we've largely talked about excitatory synapses.
• That is, when a neuron fires, it sends activation down it's synapses to post synaptic neurons making there activation increase.
• For chemical synapses, this is done by releasing neuro transmitters. Activation is a proxy for these chemicals.
• Synapses can also be inhibitory, so that they reduce activation.
• The computational models that we have typically have different parameters for each of these.
• So, inhibitory synapses may be faster than excitatory ones.
