What is another name for a reverberating circuit?
Also called a reverberatory circuit. See also phase sequence. From: reverberating circuit in A Dictionary of Psychology » Subjects: Science and technology — Psychology reverberating circuit n.
What causes a reverberatory circuit?
Such circuits are caused by positive feedback within the neuronal circuit that feeds back to re-excite the input of the same circuit. Consequently, once stimulated, the circuit may discharge repetitively for a long time. Several possible varieties of reverberatory circuits are shown in Figure 46-14.
What is the meaning of reverbatory circuit?
REVERBERATORY CIRCUIT. Neural circuits which as essentially always active, allowing impulses to repeatedly circulate after having been triggered by an initial stimulus response, making on-demand recall of information available. Also known as: reverberating circuit. REVERBERATORY CIRCUIT: "Reverberatory circuits have only been demonstrated in...
What is the difference between inhibition and inhibition in reverberating circuits?
A reverberating circuit that does not fatigue enough to stop reverberation is a source of continuous impulses. And excitatory impulses entering the reverberating pool can increase the output signal, whereas inhibition can decrease or even extinguish the signal.
What is a converging and diverging circuit?
Divergence allows one neuron to communicate with many other neurons in a network. Convergence allows a neuron to receive input from many neurons in a network.
What is an afferent circuit?
Nerve cells that carry information toward the central nervous system (or farther centrally within the spinal cord and brain) are called afferent neurons; nerve cells that carry information away from the brain or spinal cord (or away from the circuit in question) are called efferent neurons.
What do diverging circuits control?
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 afferent and efferent?
Afferent neurons carry information from sensory receptors of the skin and other organs to the central nervous system (i.e., brain and spinal cord), whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body.
What are the 4 neural circuits?
There are four principal types of neural circuits that are responsible for a broad scope of neural functions. These circuits are a diverging circuit, a converging circuit, a reverberating circuit, and a parallel after-discharge circuit. In a diverging circuit, one neuron synapses with a number of postsynaptic cells.
What is divergent circuit?
Divergence allows one neuron to communicate with many other neurons in a network. Convergence allows a neuron to receive input from many neurons in a network. Lateral inhibition. A presynaptic cell excites inhibitory interneurons and they inhibit neighboring cells in the network.
How do Retrobeads work?
The fact that retro-beads can retrogradely label neurons suggests that they are internalized via mechanisms and pathways mediating the uptake and transport of neurotrophic factors, i.e. receptor independent pinocytosis or caveole dependent endocytosis.
What is anterograde and retrograde tracing?
Anterograde tracing outlines neurons from their cell bodies to the terminals of their axons; while retrograde tracing outlines neurons in the opposite direction, from the terminals of their axons to their cell bodies.
What would happen if there were no Schwann cells?
Muscles would not be able to contract and the body would be paralyzed. What would happen if there were no Schwann cells? A neuron in the aorta detects oxygen content in the blood and relays this information to the brain.
What are the 3 rules for a series circuit?
In summary, a series circuit is defined as having only one path through which current can flow. From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a larger, total voltage.
Is the brain a circuit?
We have 86 billion neurons in our brains, and they're connected to each other, each neuron has about 10,000 inputs, connections. So, the circuit is the path that the electrical activity follows as it moves from one nerve cell to the next, to the next, to the next.
