Neurochemical

The NDE leaves individuals who experience it with a true, sometimes horrific memory, regardless of whether it is just a lack of oxygen, some kind of anaesthetic, or a neurochemical response to trauma.

Some experts say that because people produce less acetylcholine as they age, drugs that inhibit that neurochemical can have a stronger effect on older people.

Dr. Larry Sherman, a neuroscientist at Oregon Health and Science University, will focus on how the biggest questions about love can help reveal neurochemical changes that have major effects on behavior.

One study from the Center for Neuroeconomics Studies at Claremont Graduate University showed significant increase in oxytocin, also known as the “neurochemical of love,” in animals after they’d spent time together.

Decay theory Decay theory states that when something new is learned, a neurochemical, physical "memory trace" is formed in the brain and over time this trace tends to disintegrate, unless it is occasionally used.

Domoic acid is a neurotoxin that inhibits neurochemical processes, causing short-term memory loss, brain damage, and, in severe cases, death in humans.

However, available evidence may range from nonverbal behaviors—including physiological responses and homologous facial displays and acoustic utterances—to neurochemical studies.

However, the neurochemical basis of psilocybin's effects on the perception of time are not known with certainty.

The direct and indirect pathways originate from different subsets of striatal medium spiny cells: They are tightly intermingled, but express different types of dopamine receptors, as well as showing other neurochemical differences.
