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 neurons that are intrinsically rhythmic are connected to each other by excitatory or inhibitory synapses, the resulting networks are capable of a wide variety of dynamical behaviors, including attractor dynamics, periodicity, and even chaos.

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 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 I asked, `` Why didn't you go into the living room to see how Mrs. Buck was ''??

`` When Mickey went to the Yankees '', says Mark Freeman, an ex-Yankee pitcher who sells mutual funds in Denver, `` DiMaggio still was playing and every day Mickey would go by his locker, just aching for some word of encouragement from this great man, this hero of his.

When he at last did go to his room, he couldn't sleep and instead paced up and down before his little image of Acala, thinking first of Charlotte's tale of the man at Ryusenji, then of his biwa and the invisible Pacific waters.

When the body died, parts of its soul known as ka ( body double ) and the ba ( personality ) would go to the Kingdom of the Dead.

When Ibn Habib's soldiers entered the camp, the Berber chieftain ’ s wife Tekfah hid Abd al-Rahman under her personal belongings to help him go unnoticed.

When the others go in to dinner Nora stays behind for a few minutes and contemplates suicide to save her husband from the shame of the revelation of her crime and ( more importantly ) to pre-empt any gallant gesture on his part to save her reputation.

When cultural movements go through revolutions from one to the next, genres tend to get attacked and mixed up, and often new genres are generated and old ones fade.

However, the story is not yet quite finished: " When the thousand years have expired, Satan will be released from his prison and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to battle, whose number is as the sand of the sea.

When Gail refused to go along with the plan, Joe sailed away and in the attempt, drowned for real, leaving Gail to be charged with his murder.
