The pruning that is associated with learning is known as small-scale axon terminal arbor pruning. Axons extend short axon terminal arbors toward neurons within a target area. Certain terminal arbors are pruned by competition. The selection of the pruned terminal arbors follow the "use it or lose it" principle seen in synaptic plasticity. This ...
In general, the majority of changes in human intelligence occur at either the onset of development, during the critical period, or during old age (see neuroplasticity). Charles Spearman , who coined the general intelligence factor "g", described intelligence as one's ability to adapt to his environment with a set of useful skills including ...
Neuroplasticity, also known as neural plasticity or just plasticity, is the ability of neural networks in the brain to change through growth and reorganization. Neuroplasticity refers to the brain's ability to reorganize and rewire its neural connections, enabling it to adapt and function in ways that differ from its prior state.
The hippocampus regulates memory function. Memory improvement is the act of enhancing one's memory. Factors motivating research on improving memory include conditions such as amnesia, age-related memory loss, people’s desire to enhance their memory, and the search to determine factors that impact memory and cognition.
Activity-dependent plasticity is a form of functional and structural neuroplasticity that arises from the use of cognitive functions and personal experience. [1] Hence, it is the biological basis for learning and the formation of new memories.
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 ...
Plasticity in the brain affects the strength of neural connections and pathways. Nonsynaptic plasticity is a form of neuroplasticity that involves modification of ion channel function in the axon, dendrites, and cell body that results in specific changes in the integration of excitatory postsynaptic potentials and inhibitory postsynaptic potentials.
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.
