Cellular memory modules preserve repressed and active chromatin states in the Polycomb group (PcG) and trithorax group (trxG) proteins by using Polycomb- and trithorax response elements, which are just DNA sequences. [3] Transcription resets and alters epigenetic marks on chromosomal memory elements that are regulated by PcG and trxG proteins. [4]
Memory transfer proposes a chemical basis for memory termed memory RNA which can be passed down through flesh instead of an intact nervous system. Since RNA encodes information [ 1 ] living cells produce and modify RNA in reaction to external events, it might also be used in neurons to record stimuli.
This slow process, referred to as consolidation, allows emotions to influence the way the memory is stored. [7] The amygdala is involved in memory consolidation, which is the process of transferring information that is currently in working memory into ones long-term memory. This process is also known as memory modulation. [7]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Body memory, the hypothesis that (traumatic) memories can be stored in individual cells outside the brain; Neuronal memory allocation, the storage of memories in the brain at the cellular level; The epigenetic state of a cell, including the nongenetic information that can be passed from parents to offspring Genomic imprinting
An African grasslands scene, similar to the environment experienced by the evolutionary ancestors of modern humans. Adaptive memory is the study of memory systems that have evolved to help retain survival- and fitness-related information, i.e., that are geared toward helping an organism enhance its reproductive fitness and chances of surviving.

Ram, ram, or RAM most commonly refers to: A male sheep; Random-access memory, computer memory; Ram Trucks, US, since 2009 List of vehicles named Dodge Ram, trucks and vans; Ram Pickup, produced by Ram Trucks; Ram, ram, or RAM may also refer to:
Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...
