Hebbian theory is a neuropsychological theory claiming that an increase in synaptic efficacy arises from a presynaptic cell's repeated and persistent stimulation of a postsynaptic cell. It is an attempt to explain synaptic plasticity , the adaptation of brain neurons during the learning process.
The book is a collection of stories of doctors and patients showing that the human brain is capable of undergoing change, including stories of recovering use of paralyzed body parts, deaf people learning to hear, and others getting relief from pain using exercises to retrain neural pathways.
Distancing is a concept arising from the work of developmental psychologists Heinz Werner and Bernard Kaplan to describe the process of establishing a subject's individuality and identity as an essential phase in coming to terms with symbols, referential language and eventually full cognition and linguistic communication.
Two molecular mechanisms for synaptic plasticity involve the NMDA and AMPA glutamate receptors. Opening of NMDA channels (which relates to the level of cellular depolarization) leads to a rise in post-synaptic Ca 2+ concentration and this has been linked to long-term potentiation, LTP (as well as to protein kinase activation); strong depolarization of the post-synaptic cell completely ...
[1] Hence, it is the biological basis for learning and the formation of new memories. [ 1 ] [ 2 ] Activity-dependent plasticity is a form of neuroplasticity that arises from intrinsic or endogenous activity, as opposed to forms of neuroplasticity that arise from extrinsic or exogenous factors, such as electrical brain stimulation - or drug ...
This second type of learning is a more rapid and insightful learning because the cell assemblies and phase sequences have already been created and now can be rearranged in any number of ways. [25] The Hebbian theory of learning implies that every experience a person encounters becomes set into the network of brain cells. Then, each time a ...
