Why there is a gap between the two neurons?
The gap between two neurons called synapse, helps in quick transmission of impulses from one neuron to another.
Other advantages of synapse are:
- Amplification of current flow
- Can be inhibitory
- Integration of many signals
- Always one-way communication i.e. unidirectional, transmitting from pre-synaptic to post-synaptic neurons
- Can be used to calsculate timing of sensory inputs
- Greater plasticity.
