Alcohol acts as a general central nervous system depressant, but it also affects some specific areas of the brain to a greater extent than others. Memory impairment caused by alcohol has been linked to the disruption of hippocampal function—particularly affecting gamma-Aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) neurotransmission which negatively impacts long-term potentiation ...
Behavioral neuropharmacology focuses on the study of how drugs affect human behavior (neuropsychopharmacology), including the study of how drug dependence and addiction affect the human brain. [2] Molecular neuropharmacology involves the study of neurons and their neurochemical interactions, with the overall goal of developing drugs that have ...
Nicotine exposure during brain development may hamper growth of neurons and brain circuits, effecting brain architecture, chemistry, and neurobehavioral activity. [1] Nicotine changes the way synapses are formed, which can harm the parts of the brain that control attention and learning. [6]
GLP-1 drugs may protect the brain from inflammation, some studies say, but others warn they may increase depression risk. ... to determine how these drugs affect cognitive abilities and mental ...
“Both types of medications improve cognitive functions like attention and working memory by optimizing neurotransmitter [chemical messenger] levels and enhancing brain network connectivity.”
Researchers found that 63% of lifetime heavy cannabis-using participants and 68% of recent cannabis users showed reduced brain activity during their working memory task. “We found that brain ...
Psychoactive drugs operate by temporarily affecting a person's neurochemistry, which in turn causes changes in a person's mood, cognition, perception and behavior. There are many ways in which psychoactive drugs can affect the brain. Each drug has a specific action on one or more neurotransmitter or neuroreceptor in the brain.
Addiction affects the brain circuits of reward and motivation, learning and memory, and the inhibitory control over behavior. [ 24 ] There are different schools of thought regarding the terms dependence and addiction when referring to drugs and behaviors.
