WK 3- NEUROPLASTICITY AND MENTAL HEALTH Flashcards
What is neuroplasticity
The ability of the brain to change over time and make new neuronal connections- occurs in response to how we use our brains
What is axonal sprouting
Occurs in response to injury- undamaged axons can grown new nerve endings and reconnect neurons whose links were damaged OR occurs when new neuronal pathways are needed
What is neurogenesis
Production of new neurons from stem cells
What are 4 types of non-pharmacological interventions in mental health

What are some advantages and disadvantages of diagnosing someone with a mental health disorder
