In addition to eliciting spike-evoked inhibitory potentials in postsynaptic cells, these neurons also release functionally significant amounts of transmitter below the threshold for action potentials. WebNov 6, 2014 · Graded synaptic release is also observed at dendrodendritic synapses in both vertebrates and invertebrates (Shepherd et al., 2007). While it is easy to appreciate the encoding of analog-like outputs by graded synapses, the question arises as to how these synapses could also encode digital-like outputs. thinkplace kenya

WebGraded potentials are small changes in membrane potential that are either excitatory (depolarize the membrane) or inhibitory (hyperpolarize the membrane). Many excitatory graded potentials have to happen at once to depolarize the cell body enough to trigger the action potential.
