As you work through this SLP assignment, you will learn more about the flexibility, or plasticity, of the brain. You have learned about how the spinal nerves can deliver messages directly to effector organs from the CNS through peripheral nerves that branch off of the spinal cord. These nerves are collections of neurons bundled in connective tissue. Neurons also communicate with each other within the CNS and establish circuits and neuronal pathways. First take some time to work through the video and image below about how neurons communicate: 1. Neurons communicate with each other 2. Synapses and neurotransmitters Throughout life, the connections between neurons in the brain develop and change according to the genetic foundations that the individual inherits from the parents, and the environmental influences to which the individual must respond. For example, the abundance of one type of neuron over another, and the neurotransmitter that each produces can be predetermined by the DNA an individual inherits. However, an individual who is exposed to chronic stress during developmental years may reinforce some response pathways more than individuals who do not experience the same patterns of stress. These points are summarized and

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
