Denisha Vassan (student number 841892)Psychology 1007 Essay 2Processes involved in brain recovery after injury or traumaThe control center of the human body is not other than the powerful brain. Due to its incredible importance in basic human functioning, both voluntary and involuntary, any injury or trauma to this organ will have a great influence on the body and its capabilities (Burrus, 2013). Exploring how the brain deals with various injuries and damages proves that brain functionality is tailored to make the brain the powerhouse of the body. But before exploring this using case studies, it is important to make sense of the anatomy and functioning of the nervous system as a whole in order to understand how it is affected during injury, the functioning of the lost body, the intervention implemented for treatment or rehabilitation and the changes experienced. The brain is part of the central nervous system, which is made up of neurons and glial cells. Neurons which are the excitable nerve cells of the nervous system that conduct electrical impulses, or signals, that serve as communication between the brain, sensory receptors, muscles, and spinal cord. In order to establish rapid communication over a long distance, neurons have evolved a special ability to send electrical signals, called action potentials, along axons. The way in which the cell body of a neuron communicates with its own endings via the axon is called conduction. For conduction to occur, an action potential which is an electrical signal that occurs in a neuron due to ions moving across the neuronal membrane, resulting in depolarization of a neuron, must be generated nearby from the cell body area of the axon.

This would result in more dopamine-releasing neurons being present in neural networks, allowing for smooth, coordinated movements (Johnson, 2012). In conclusion, normal functioning of the brain and nervous system is vital for basic bodily functions. operation and process. An injury, disease, or abnormal structure of the brain will greatly affect behavior, emotional regulation, mental processes, and functioning. The brain will respond to any trauma, injury or abnormality to adapt to the dysfunction. During this response, the brain will physically change, a process called neuroplasticity, and attempt to “rewire” the brain to return to normal functioning. In the treatment of many cases, as previously stated, the goal was to reconnect neurons and the theory of neuroplasticity was the foundation...
