The stage when the human brain is developing is possibly the most sensitive time period to the effects of nicotine. [104] When the brain is being developed, activating or desensitizing nicotinic acetylcholine receptors by being exposed to nicotine can result in long-term developmental disturbances. [90]
Activity-regulated cytoskeleton-associated protein is a plasticity protein that in humans is encoded by the ARC gene. The gene is believed to derive from a retrotransposon. [5] The protein is found in the neurons of tetrapods and other animals where it can form virus-like capsids that transport RNA between neurons. [5]

Brain plasticity — also called neuroplasticity — is an odd term for most people, with the word “plastic” causing images of Tupperware or Saran Wrap to pop into your head.
Neuroplasticity, also known as neural plasticity or just plasticity, is the ability of neural networks in the brain to change through growth and reorganization. Neuroplasticity refers to the brain's ability to reorganize and rewire its neural connections, enabling it to adapt and function in ways that differ from its prior state.
Perceptual narrowing is a developmental process during which the brain uses environmental experiences to shape perceptual abilities. This process improves the perception of things that people experience often and causes them to experience a decline in the ability to perceive some things to which they are not often exposed.
Activity-dependent plasticity is seen in the primary visual cortex, a region of the brain that processes visual stimuli and is capable of modifying the experienced stimuli based on active sensing and arousal states. It is known that synaptic communication trends between excited and depressed states relative to the light/dark cycle.
A National Institute on Drug Abuse video entitled Anyone Can Become Addicted to Drugs. [21]Nicotine dependence is defined as a neurobiological adaptation to repeated drug exposure that is manifested by highly controlled or compulsive use, the development of tolerance, experiencing withdrawal symptoms upon cessation including cravings, and an inability to quit despite harmful effects.
