Use of this technology has led to a better understanding of which brain regions regulate mood and how other functions such as memory may be affected by depression. However there are still hundreds of chemicals that we are exposed to in the environment for which we do not have any information on their potential neurotoxicity on the nigrostriatal dopamine system.

Diseases such as Alzheimers epilepsy and Parkinsons are associated with deficits in certain neurotransmitters. Brain development also does not. In a recent experiment scientists assayed brain tissue from 35-day-old rat pups and found that pups that had been exposed to nicotine in utero had fewer nicotinic acetylcholine receptors in the reward system than unexposed rats.
The major types of brain lesions are listed below along with an example within that category. Be aware that brain systems do not all develop at the same time or at the same rate. Although no cure exists scientific research aimed at finding effective treatments for HD is underway.
Brain areas affected by drug use include. The word pathology also refers to the study of disease in general incorporating a wide range of biology research fields and medical practices. Pathology is the study of the causes and effects of disease or injury.
In mammals the cerebral cortex tends to show large slow delta waves during sleep faster alpha waves when the animal is awake but inattentive and chaotic-looking irregular activity when the animal is actively engaged in a task called beta and gamma waves. Or axons may be very long such as those that carry messages from the brain all the way down the spinal cord.

Opioid tolerance dependence and addiction are all manifestations of brain changes resulting from chronic opioid abuse. A major ad campaign in the 80s aimed to prevent drug use by showing how drugs hurt the brain.
Animal studies have shown that choline is essential for optimal brain development and influences cognitive function in later life. Image The basal ganglia which play an important role in positive forms of motivation including the pleasurable effects of healthy activities like eating socializing and sex and are also involved in the formation of habits and routines.
