Waddington called the effect he had seen "genetic assimilation". His explanation was that it was caused by a process he called "canalization".He compared embryonic development to a ball rolling down a slope in what he called an epigenetic landscape, where each point on the landscape is a possible state of the organism (involving many variables).
In evolutionary biology, the Baldwin effect describes an effect of learned behaviour on evolution. James Mark Baldwin and others suggested that an organism's ability to learn new behaviours (e.g. to acclimatise to a new stressor) will affect its reproductive success and will therefore have an effect on the genetic makeup of its species through ...
Assimilation is the process of absorption of vitamins, minerals, and other chemicals from food as part of the nutrition of an organism. In humans, this is always done with a chemical breakdown ( enzymes and acids ) and physical breakdown (oral mastication and stomach churning).
Assimilation is how humans perceive and adapt to new information. It is the process of fitting new information into pre-existing cognitive schemas. [18] Assimilation in which new experiences are reinterpreted to fit into, or assimilate with, old ideas and analyzing new facts accordingly. [19]
A study showed that a low dose (0.1 mg/kg) of psilocybin given to mice increased neurogenesis in the hippocampus 2 weeks after administration, while a high dose (1 mg/kg) significantly decreased neurogenesis. [32] No orally-available drugs are known to elicit neurogenesis outside of the already neurogenic niches.

Equilibration encompasses both assimilation and accommodation as the learner changes how they think to get a better answer. Piaget believed that knowledge is a biological function that results from the actions of an individual through change.
Molecular neuroscience is a branch of neuroscience that observes concepts in molecular biology applied to the nervous systems of animals. The scope of this subject covers topics such as molecular neuroanatomy, mechanisms of molecular signaling in the nervous system, the effects of genetics and epigenetics on neuronal development, and the molecular basis for neuroplasticity and ...
