Central Inhibition

 

an active nervous process arising in the central nervous system and leading to the suppression or prevention of excitation. A distinction is made between postsynaptic inhibition, which involves the action of a specific mediator on the postsynaptic membrane of a neuron, and presynaptic inhibition, which is based on the depolarization of a presynaptic nerve ending at the point of contact with another axonal nerve ending. All types of inhibition occurring in conditioned reflex activity are regarded as forms of central inhibition.

The role of central inhibition in ambiguity resolution
Without the specification of a goal state (or reason for selecting), this kind of central inhibition would not come into play.
To make the connection between central inhibition and lexical ambiguity resolution stronger it is first crucial to see whether it is possible to observe semantic negative priming from the non-selected meaning of the homograph.
The impact of individual strategies on central inhibition
One way to test the role of central inhibition in homograph resolution is to check for strategic effects on priming.
Inhibitory mechanisms can be divided into two kinds: central inhibition and lateral inhibition.
If central inhibition works to resolve ambiguity, then some kind of negative priming should occasionally be observed.
Instead, when the selection of the meaning is generated internally, depending on the goal of the task, then central inhibition should act with higher intensity, allowing us to observe negative priming.
Our results show that cognitive improvement with Exelon in Alzheimer's disease may be associated with central inhibition of both acetylcholinesterase and butyrylcholinesterase, and support a role for both enzymes in modulating cholinergic function in Alzheimer's disease," said Dr.
