|
neural circuits |
billions of neurons organized into complicated networks, functional groups of neurons that process specific types of information |
|
|
simple series circuit |
a presynaptic neuron stimulates a single postsynaptic neuron,the second the stimulates another, and so on |
|
|
divergence |
a single presynaptic neuron may synapse with several postsynaptic neurons |
|
|
diverging circuit |
the nerve impulse from a single presynaptic neuron causes the stimulation of increasing numbers of cells along the circuit |
|
|
convergence |
several presynaptic neurons synapse with a single postsynaptic neuron, permits more effective stimulation or inhibition of the postsynaptic neuron |
|
|
converging circuit |
the postsynaptic neuron recieves nerve impulses from several different sources |
|
|
reverberating circuit |
circuit that is organized so that stimulation of the presynaptic cell causes the postsynaptic cell to transmit a series of nerve impluses - breathing, coordinated muscular activities, waking up, and short-term memory |
|
|
parallel after discharge circuit |
a single presynaptic cell stimulates a group of neurons, each of which synapses with a common postsynaptic cell, a differing number of synapses between the first and last neurons imposes varying synaptic delays so that the last neuron exhibits multiple EPSPs or IPSPs - mathematical calculations |
