21. Together this results in an action potential in sensory neurons and the activation of inflammasomes. 22. Recent investigations discovered opioid receptors on peripheral sensory neurons . 23. Instead the bipolar sensory neuron synapses directly on a motor neuron in the spinal cord. 24. The sensory neurons report on mechanical and chemical conditions. 25. Microarrays have been used to determine many genes downstream of Brn3a in peripheral sensory neurons . 26. A study published in 2006 showed that methylation helps for allelic exclusion in sensory neurons . 27. The metabolites have been shown to be more toxic to sensory neurons than to motor neurons. 28. Each sensory neuron within a nerve net responds to each stimulus, like odors or tactile stimuli. 29. These ganglia contain cell bodies of sensory neurons . 30. These neurons can be very abundant, for example Drosophila flies have 2, 600 olfactory sensory neurons .
