Figure 7.1 Schematic drawing of some of the signals that occur after injury in neurons
and in the growth cone at the tip of the axon. After injury, there are both positive and
negative injury signals that elicit a number of different events in the nerve cell body and
in the nucleus of the neuron; all with the purpose to turn the neuron into a regenerative
state instead of transmitting state (A). There is a close contact between the sprout with
