One form of behavioral neuropharmacology focuses on the study of drug dependence and how drug addiction affects the human mind. Most research has shown that the major part of the brain that reinforces addiction through neurochemical reward is the nucleus accumbens. The image to the right shows how dopamine is projected into this area.
The Partnership used a simple advertisement showing an egg in a frying pan, similar to this photo, suggesting that the effect of drugs on a brain was like frying an egg on a hot pan. This Is Your Brain on Drugs was a large-scale US anti- narcotics campaign by Partnership for a Drug-Free America (PDFA) launched in 1987, that used three televised ...
Harvey dissected the brain into about 240 blocks (each about 1 cm 3) and encased the segments in a plastic-like material called collodion. [5] [6] Harvey also removed Einstein's eyes. He gave them to Henry Abrams, Einstein's ophthalmologist. [4] Whether or not Einstein's brain was preserved with his prior consent is a matter of dispute.
addictive drug – psychoactive substances that with repeated use are associated with significantly higher rates of substance use disorders, due in large part to the drug's effect on brain reward systems; dependence – an adaptive state associated with a withdrawal syndrome upon cessation of repeated exposure to a stimulus (e.g., drug intake)
Drug-induced intracranial hypertension (DIIH) or medication-induced intracranial hypertension is a condition of higher than normal intracranial pressure with the main cause being a drug. [15] This condition is similar to idiopathic intracranial hypertension , however the etiology in this instance is a drug. [ 16 ]
ADHD medication tied to 19% lower death risk. An observational study conducted in Sweden, whose results appeared in JAMA in March 2024, further emphasized the positive impact of ADHD medication on ...
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption ...
Blood-brain barrier: this is located between the blood plasma in the cerebral blood vessels and the brain's extracellular space. The presence of this barrier makes it hard for a drug to reach the brain. Placental barrier: this prevents high concentrations of a potentially toxic drug from reaching the foetus.
