One simplified way to understand these effects is to consider excitation and inhibition simply in terms of algebraic signs. We are all familiar with the effect of multiplying positive and negative numbers, which is the point of the exercise below. 1. In Example below 1, how many ways can you produce a + result? A negative result? 2. In example 2, how many ways can you produce a + result? 3. In Example 3, what is the result without the box; with the box? 1. x + = + 3 2.

The Different Effects of Excitation and Inhibition in Neural Circuit (series #1)| Neural circuit consists of polysynaptic neural network, combination of excitatory and inhibitory neurons. This exercise helps to understand the effects of excitation and inhibition in the nervous system. Our body is dynamically active under physiology condition. As a result, there are basal levels of activity such as 70 beats/min of heart rate at resting condition. Either increased or decreased activities are relative to the baseline. The effects of excitation are easily understood---one neuron activates another neuron. However, when inhibition is introduced into circuits, analysis become more complicated. In fact, the numbers of inhibitory neurons in the circuit determine the final effect of the circuit, which can be excitation or inhibition, on the target organ or area. We assume all excitatory and inhibitory neurons are glutamate and GABA neurons, respectively, in this practice sheet. The glutamate and GABA neurons generate EPSP and IPSP, resulting in depolarization and hyperpolarization on the postsynaptic membrane, respectively. Excitatory neuron Inhibitory neuron 1. 2. 3. 4.
