Cellular memory

from Wikipedia, the free encyclopedia

Cellular memory describes the concept that individual cells can have a memory.

Life Science and Medicine

Rats that voluntarily consume cocaine in a solution for a longer period of time show a change in synaptic activity that continues several months after withdrawal , which affects the release of the neurotransmitter dopamine in the brain's reward center. This effect, known as cellular memory , is considered to be partly responsible for relapses in previously treated addicts.

Recent scientific studies show that individual cells also have an at least short-term memory for external stimuli in the form of electricity or heat.

Alternative medicine and esotericism

In a study published in 2000, changes in behavior in ten heart transplant recipients were examined and compared with the personalities of the donors. In all cases, two to five new behavior patterns were found in the recipients , which the respective donor had also exhibited.

There are no other generally recognized scientific studies, so that the possible personality changes are viewed with skepticism by evidence-based medicine .
