Old School RuneScape is a massively multiplayer online role-playing game (MMORPG), developed and published by Jagex.The game was released on 16 February 2013. When Old School RuneScape launched, it began as an August 2007 version of the game RuneScape, which was highly popular prior to the launch of RuneScape 3.
In the nervous system, a synapse [1] is a structure that allows a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or a target effector cell. Synapses can be classified as either chemical or electrical, depending on the mechanism of signal transmission between neurons.
The strength of a synapse has been defined by Bernard Katz as the product of (presynaptic) release probability pr, quantal size q (the postsynaptic response to the release of a single neurotransmitter vesicle, a 'quantum'), and n, the number of release sites. "Unitary connection" usually refers to an unknown number of individual synapses ...
The synapse is formed at a narrow gap between the pre- and postsynaptic neurons known as a gap junction. At gap junctions, such cells approach within about 3.8 nm of each other, [ 1 ] a much shorter distance than the 20- to 40-nanometer distance that separates cells at a chemical synapse . [ 2 ]
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]
A synapse during re-uptake. Note that some neurotransmitters are lost and not reabsorbed. Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse.
The neurotransmitters are released by the synapse to propagate the signal to the postsynaptic cell. It has also been hypothesized that synaptic fatigue could be a result of postsynaptic receptor desensitization or changes in postsynaptic passive conductance , but recent evidence has suggested that it is primarily a presynaptic phenomenon.
Hebbian learning is increasingly being linked to cognitive processes like decision-making and social learning. Cognitive neuroscience has started to explore the intersection of Hebbian theory with brain regions responsible for reward processing and social cognition, such as the striatum and prefrontal cortex.
