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.

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 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 owner of the cargo and the carrier are separate corporations, marine cargo insurance typically compensates the owner of cargo for losses sustained from fire, shipwreck, etc., but excludes losses that can be recovered from the carrier or the carrier's insurance.

When they fire, they release substances called neuropeptides that induce a cascade of reactions that cause pain in the bladder wall.

When Scripture says, ‘ The Lord rained fire from the Lord out of heaven ,’ the prophetic word indicates that there were two in number: One upon the earth, who, it says, descended to behold the cry of Sodom ; Another in heaven, who also is Lord of the Lord on earth, as He is Father and God ; the cause of His power and of His being Lord and God.

When battle was near, it was drawn out ; then it roared and struggled against its thongs, fire flashed from it, and it tore through the ranks of the enemy once slipped from the leash, never tired of slaying.

When the compound word was formed endings were removed ... Perhaps they used the peat for fire and blacksmithery hence the association with fire, and light.

When the magneto is supposed to fire, the flyweights are released by the action of the body contacting the trigger ramp.

When the bottle smashes on impact, the ensuing cloud of petrol droplets and vapour ignites, causing an immediate fireball followed by a raging fire as the remainder of the fuel is consumed.
