Chapter 5- Brain plasticity and brain inury Flashcards
Neuroplasticity
The ability of the brain to change in response to experience this includes the Brains capacity to recover from all compensate loss of function through injury
experience-expectant plasticity
involves brain change in response to environmental experience that is ordinarily expected, for example important to have exposure to light and patterns, visual information early in life for development of the visual cortex. time dependent
experienced-dependent plasticity
Brain change that modify some part of the neural structure that is already present. It is not time dependent for example piano have larger than usual cortical areas for finger control. This is due to the growth of the synapses , their connections and the greater density of the synaptic connections.
Phineas Cage case study
25-year-old Phineas cage had a rod blow to his cheek and threw the top of his skull. He suffered a massive head injury. That seriously entered his frontal load. He was once friendly, considerate, and quietly spoken, but was reported to become impatient, crudely, spoken, aggressive, and irresponsible and hard to get along with he died 12 years later
