AP PSYCHOLOGY

Detailed explanation-1: -Sensory neurons are the nerve cells that are activated by sensory input from the environment-for example, when you touch a hot surface with your fingertips, the sensory neurons will be the ones firing and sending off signals to the rest of the nervous system about the information they have received.

Detailed explanation-2: -Neuroplasticity is the brain’s ability to change and adapt due to experience. It is an umbrella term referring to the brain’s ability to change, reorganize, or grow neural networks. This can involve functional changes due to brain damage or structural changes due to learning.

Detailed explanation-3: -Irritability refers to the ability of neurons (cells of the nervous system) to detect and to respond to a stimulus.

Detailed explanation-4: -Functional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity. It may be used to examine which parts of the brain are handling critical functions, evaluate the effects of stroke or other disease, or to guide brain treatment.
