A delta fibers <Aδ fibers> [Am.]

• After a nerve lesion of either C fibers or Aδ fibers, they become abnormally sensitive and cause pathological spontaneous activity.
• A delta fibers (Aδ fibers) and C fibers carrying pain sensation in the spinothalamic tract contribute to this commissure, as do fibers of the anterior corticospinal tract, which carry motor signals from the primary motor cortex.
• These fibers, categorized as C fibers and small Aδ fibers, are present in skin, peripheral nerves, and organs.
• Afferents responding to noxious stimuli are known as nociceptors. There are 2 main groups, unmyelinated C afferents and small myelinated Aδ fibers. Most studies are focused on C nociceptors.
• Fast-conducting Aβ and Aδ-fibers provide the lowest stimulus intensities (typically referred to as prepain sensations), and those sensations eventually receive higher stimulation levels.

• The first are the Aδ fiber axons. They are myelinated and can allow an action potential to travel at a rate of about 20 meters/second towards the CNS.
• There are four main types of sensory fibres responsible for somatosensation: Aα, Aβ, Aδ and C fibres (more details can be found at the axon page).
• An electrical current can be applied to the tooth in order to generate an action potential in the Type Aδ fibres within pulp, eliciting a neurological response.
