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. It was introduced by Donald Hebb in his 1949 book ...
Children learn by building up these cell assemblies and phase sequences. An enriched environment with varied opportunities for sensory and motor experiences contribute to children developing the cell assemblies and phase sequences necessary for continued learning in adulthood. To attempt to prove this, Hebb and his daughters raised pet rats at ...
Psychiatry, psychology. Emotional and behavioral disorders (EBD; also known as behavioral and emotional disorders) [ 1 ][ 2 ] refer to a disability classification used in educational settings that allows educational institutions to provide special education and related services to students who have displayed poor social and/or academic progress.
Synapse. Diagram of a chemical synaptic connection. In the nervous system, a synapse[1] is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. Synapses are essential to the transmission of nervous impulses from one neuron to another, [2] playing a key role ...
The positive behavior support process involves identifying goals, then undertaking functional behavior assessment (FBA). FBAs clearly describe behaviors, identify the contexts (events, times, and situation) that predict when behavior will and will not occur, and consequences that maintain the behavior. The FBA includes a hypothesis about the ...
Excitatory synapse. A diagram of a typical central nervous system synapse. The spheres located in the upper neuron contain neurotransmitters that fuse with the presynaptic membrane and release neurotransmitters into the synaptic cleft. These neurotransmitters bind to receptors located on the postsynaptic membrane of the lower neuron, and, in ...
Synaptogenesis is the formation of synapses between neurons in the nervous system. Although it occurs throughout a healthy person's lifespan, an explosion of synapse formation occurs during early brain development, known as exuberant synaptogenesis. [ 1 ] Synaptogenesis is particularly important during an individual's critical period, during ...
The size of the neuron can also affect the inhibitory postsynaptic potential. Simple temporal summation of postsynaptic potentials occurs in smaller neurons, whereas in larger neurons larger numbers of synapses and ionotropic receptors as well as a longer distance from the synapse to the soma enables the prolongation of interactions between neurons.
