Table 6.1. Salient features of a biological neuron
# Feature
1 The body of the neuron is called the soma that acts as a processing element to receive numerous
signals through the dendrites simultaneously.
2 The strengths of the incoming signals are modi ed by the synaptic gaps.
3 The role of the soma, i.e., the processing element of a neuron, is simple. It sums up the weighted
input signals and if the sum is suf ciently high, it transmits an output signal through the axon. The
output signal reaches the receiving neurons in the neighbourhood through the axon terminals.
4 The weight factors provided by the ...
