What is a reverberating circuit?
a neural circuit in which nerve impulses that were initially activated in response to stimuli are more or less continuously reactivated so that retrieval of information on demand is possible.
What is a converging circuit in anatomy?
In a converging circuit, inputs from many sources are converged into one output, affecting just one neuron or a neuron pool. This type of circuit is exemplified in the respiratory center of the brainstem, which responds to a number of inputs from different sources by giving out an appropriate breathing pattern.
What is a diverging circuit?
In a diverging circuit, one nerve fiber branches and synapses with several postsynaptic cells. Each of those may synapse with several more, so input from just one neuron may produce output through dozens of neurons.
What are the three neural circuits?
These three classes—afferent neurons, efferent neurons, and interneurons—are the basic constituents of all neural circuits. Neural circuits are both anatomical and functional entities.
What is an example of diverging circuit?
On the other hand, circuits may either diverge (one neuron connecting to many) or converge (many neurons connecting to one). Their arrangement is an aspect of their function. A diverging circuit of sensory neurons, for example, would split in terms of the areas of the brain to which the sensory input goes.
What is wrong with Polyvagal theory?
Criticisms of Polyvagal Theory has failed to acknowledge the theory’s emphasis on the unique structural and functional changes in the regulation of the autonomic nervous system that occurred during the evolutionary transition from asocial reptiles to social mammals.
How do neural circuits develop?
Neural Circuit Development During Early and Middle Childhood Synaptic density peaks first in primary sensory areas, followed by the association areas and then the PFC, cortices that subserve higher cognitive functions. Similarly, local cortical connections appear before more distant ones.
