When the antidromic stimulus reaches the motor neuron cell bodies, a small portion of the motor neurons backfire and orthodromic wave travels back down the nerve towards the muscle.

When blood flow is suppressed, glutamate is released from presynaptic neurons causing NMDA and AMPA receptor activation moreso than would normally be the case outside of stress conditions, leading to elevated Ca < sup > 2 +</ sup > and Na < sup >+</ sup > entering the post synaptic neuron and cell damage.

When nociceptors are stimulated they transmit signals through sensory neurons in the spinal cord.

When action potentials from multiple presynaptic neurons fire simultaneously, or if a single presynaptic neuron fires at a high enough frequency, the EPSPs can overlap and summate.

When reelin is absent, like in the mutant reeler mouse, the order of cortical layering becomes roughly inverted, with younger neurons finding themselves to be unable to pass the settled layers.

When the neighborhood has shrunk to just a couple of neurons, the weights are converging to local estimates.

When a person decides to walk across a room, it is generally understood that the decision to do so, a mental event, immediately causes a group of neurons in that person's brain to fire, a physical event, which ultimately results in his walking across the room.

Most transmissions occur in two stages: When stimulated, the preganglionic nerve releases ACh at the ganglion, which acts on nicotinic receptors of postganglionic neurons.

When neurons become active, local blood flow to those brain regions increases, and oxygen-rich ( oxygenated ) blood displaces oxygen-depleted ( deoxygenated ) blood around 2 seconds later.

When neurons go active, getting them back to their original ( polarized ) state requires actively pumping ions back and forth across the neuronal cell membranes.

When the head moves, the neurons under a voxel move and hence its timecourse now represents largely that of some other voxel in the past.

When these neurons no longer carry on sprouting, fatigue occurs due to the increasing metabolic demand of the nervous system.

When they are activated by these inputs, the medium spiny neurons ' projections release GABA onto the ventral pallidum.

When the ipsilateral striatum of an adult toad was electrically stimulated, inhibitory postsynaptic potentials were induced in binocular tegmental neurons, which affects the visual system of the toad.

When the head moves vertically, the sensory cells of the saccule are disturbed and the neurons connected to them begin transmitting impulses to the brain.

When a reflex arc consists of only two neurons in an animal ( one sensory neuron, and one motor neuron ), it is defined as monosynaptic.

Hans Moravec addressed the above arguments (" brains are more complicated ", " neurons have to be modeled in more detail ") in his 1997 paper " When will computer hardware match the human brain ?".

When neurons in the DRG fire, impulses travel down the phrenic and intercostal nerves to stimulate the diaphragm and external intercostal muscles.

When the thalamic-pretectal region was stimulated, the toad exhibited escape responses, but when the tectum was stimulated in an area close to prey-selective neurons, the toad engaged in prey catching behavior ( Carew 2000 ).

When the glutamatergic neurons are activated, the firing rates of the dopamine neurons increase in the VTA and induce burst firing.

When activated, these neurons can produce ravenous eating.

When contrasted with the peripheral nervous system ( PNS ), the neurons of the central nervous system ( CNS ), including the brain, are all interneurons.

When invading grey matter structures such as cortex, the neoplastic oligodendrocytes tend to cluster around neurons exhibiting a phenomenon referred to as “ perineuronal satellitosis ”.

When the Know-nothings get control, it will read, All men are created equal except Negroes and foreigners and Catholics.

When the reactionary response is thus bolstered by an intellectual defense, the characteristics of that defense are explicable only in terms of the basic attitudes of unanalyzed reaction.

When combined with the metaphysical notion that pure forms of this universe are best appreciated when least embodied in a material substratum, it becomes clear that while earth will be dross on a scale of material-formal ratios, celestial bodies will be of a subtle, quickened, ethereal existence, in whose embodiment pure form will be the dominant component and matter will be absent or remain subsidiary.

She used to tell me, `` When I stand there and look at the flag blowing this way and that way, I have the wonderful, safe feeling that Americans are protected no matter which way the wind blows ''.

When we consider the disorganized state of the world community, and the legacy of predispositions adversely directed against all who are identified as Jews, it is obvious that the struggle for the minds and muscles of men needs to be prosecuted with increasing vigor and skill.

When these fields are surveyed together, important patterns of relationship emerge indicating a vast community of reciprocal influence, a continuity of thought and expression including many traditions, primarily literary, religious, and philosophical, but frequently including contact with the fine arts and even, to some extent, with science.

When different colors are used, she is just as likely to color trees purple, hair green, etc..

When painting, Mason's physical eyes are half-closed, while his mind's eye is wide open, and this circumstance accounts in part for the impression he wishes to convey.
