Brain cell destruction or decline characterizes brain injuries, which result from various internal and external factors. Typically, brain injury denotes non-selective trauma-induced damage, while neurotoxicity refers to chemically induced neuron injury.
Types of brain injury include traumatic brain injury (TBI) and acquired brain injury.
Behavioral neuroscience, known as biological psychology, biopsychology, or psychobiology, applies biological principles to understand the physiological, genetic, and developmental aspects of behavior in humans and animals.
Topics in behavioral neuroscience include sensation and perception, motivated behaviors (such as hunger, thirst, and sex), control of movement, learning and memory, sleep, and biological rhythms, as well as emotion.
