That three-pound lump of gray matter contains 100 billion neurons and 100 trillion synapses, or connections.
And the toxin, which sits in the synapses between neurons, can take weeks to wash out.
But inevitably his synapses took hold, the neuronic links grooved, and to Gral one thought emerged: the vines would never do.
Just pure pain, applied directly to the synapses of his brain.
They are supposed to be due to a change at the synapses connecting neurone with neurone in the grey matter.
The point where the greatest change seems to take place is at the synapses, but what this modification is, no one knows.
Thus may be produced growth of axons in certain directions, and synapses of this cell with that.
If the same stimulus be often repeated, the synapses between groups of cells may become permanent.
The higher organisms are more adaptable, because there is more to be modified in them,—more nerves and synapses, more pliability.
It was over now, but his synapses were still crackling with the memories of those burning lashes of energy.
"junction between two nerve cells," 1899, from Greek synapsis "conjunction," from synaptein "to clasp," from syn- "together" (see syn-) + haptein "to fasten." Related to apse. Introduced by English physiologist Sir Michael Foster (1836-1907) at the suggestion of English classical scholar Arthur Woollgar Verral (1851-1912).
synapse syn·apse (sĭn'āps', sĭ-nāps')
The junction across which a nerve impulse passes from an axon terminal to a neuron, a muscle cell, or a gland cell.
synapsis syn·ap·sis (sĭ-nāp'sĭs)
n. pl. syn·ap·ses (-sēz)
The side-by-side association of homologous paternal and maternal chromosomes during early meiotic prophase.
The small junction across which a nerve impulse passes from one nerve cell to another nerve cell, a muscle cell, or a gland cell. The synapse consists of the synaptic terminal, or presynaptic ending, of a sending neuron, a postsynaptic ending of the receiving cell that contains receptor sites, and the space between them (the synaptic cleft). The synaptic terminal contains neurotransmitters and cell organelles including mitochondria. An electrical impulse in the sending neuron triggers the migration of vesicles containing neurotransmitters toward the membrane of the synaptic terminal. The vesicle membrane fuses with the presynaptic membrane, and the neurotransmitters are released into the synaptic cleft and bind to receptors of the connecting cell where they excite or inhibit electrical impulses. See also neurotransmitter.
