Reports on evidence that toluene abuse can harm the nervous system and body, although scientists know relatively little about its specific actions.
Reports on a study involving researchers who successfully desensitized mice to cocaine by genetically altering their dopamine transporters.
Describes new tools under development, including one to visualize cells deep in the brain and another one that remotely activates brain cells.
Presents research findings linking 89 genes to drug abuse and dependence, found using genome-wide association studies, a new technique for identifying genes.
Describes research findings demonstrating that the immune system participates in the shaping of brain circuits during a child's development, a finding that may shed light on the origins of neurodegenerative diseases.
Discusses research exploring how widespread the reduction of neural activity is in the brain with chronic exposure to cocaine.
Describes research findings showing differences in protein concentrations in the brain pleasure centers of people who died from cocaine overdose as compared with those who did not abuse the drug.
Reports on three separate imaging studies illuminating the neurobiology of cigarette craving.
Describes research with rats to better understand cocaine’s effect on the neural signaling in the learning circuits of the brain.
Reports on a series of animal experiments indicating that nicotine exposure during prenatal fetal development damages a set of receptors in the brain's auditory processing center.
