Chapter 2 Review Notes
... A neural impulse fires when the neuron is stimulated by pressure, heat, light, or chemical messages from adjacent neurons. Received signals trigger an impulse only if the excitatory signals minus the inhibitory signals exceeds a minimum intensity called the threshold. The neuron’s reaction is an all ...

Nothing worth reading has been written on it.” The problem arises because although consciousness must come from a physical structure, no one has been able to work out how.
