Achild that is not stimulated with a normal environment is likely to show

The child have fewer neural synapses than a stimulated child. In our nervous system, synapses are structures that allows neurons to conduct electrical impulse from each other. Synapses transmits information via electrical or chemical means. In chemical synapses, the electrical activity is converted into the release of neurotransmitter that binds in to the receptors that can be found in the post synaptic membrane.In Electrical impulse, the pre and post synaptic cell membranes are connected by synaptic clefts. This allow the passage of  electrical current causing changes in the voltage in the presynaptic cell and induce voltage change in the post synaptic area.
