00:04Neuroplasticity refers to the brain's ability to change and adapt throughout life.
00:09This includes the ability to strengthen or weaken connections between neurons, form new
00:14connections between neurons, and reorganize neural circuits in response to experience.
00:20At the most basic level, neuroplasticity often involves changes at synapses, which are the
00:25points of communication between neurons.
00:27When neurons communicate repeatedly, the connections between them can become stronger, a process
00:33known as long-term potentiation.
00:36Different patterns of neural activity, such as changes in the timing or frequency of neuron
00:41firing, can instead weaken these connections through a process called long-term depression.
00:46These forms of synaptic plasticity are thought to be important cellular mechanisms underlying
00:51learning and memory.
00:54Neuroplasticity can occur in response to a wide range of experiences.
00:58Learning a new skill, practicing a behavior, or being exposed to a new environment can all
01:03alter patterns of neural connectivity.
01:06Over time, these changes can modify how information is processed in the brain and improve performance
01:11on certain tasks.
01:14Neuroplasticity also plays an important role in recovery from brain injury.
01:18After damage to part of the brain, surviving neural circuits can sometimes reorganize and
01:24partially compensate for functions previously supported by the damaged area.
01:28Although this compensation is often incomplete, it can contribute to partial recovery of abilities
01:33such as movement, sensation, or language.
01:37While neuroplasticity allows the brain to adapt in beneficial ways, it can also contribute to
01:42maladaptive changes.
01:44For example, plasticity-related changes in neural circuits may play a role in chronic pain
01:49brain injury.
01:50And many other neurological or psychiatric conditions.
