Following administration of an opiate drug, "pain signals" are prevented from getting out of the spinal cord via two mechanisms. One inhibits spinal cord neurons that communicate with the parafascicular nucleus of the thalamus. What is the other way that pain signals are stopped? dendro-dendritic synapses that enhance IPSI's in somatosensory neurons. the disinhibition of long axons that start in the spinal cord and influence free nerve endings directly. feedback loop to the periaquedictal grey of the midbrain, which enhances neural activity in that area. axo-axonic synapses that prevents somatosensory neurons from releasing neurotransmitter.

You are recording from a touch receptor in skin. When you stimulate a spot on the skin, the receptor fires continuously until you stop the skin stimulation. Which of the following pieces of information would you need to be able to identify what kind of receptor this is? Group of answer choices Whether the area of skin that can activate this receptor is big or small Whether the receptor sends its output to the somatosensory cortex or not You don’t need any more information; you can identify this receptor just from the information provided Whether the touch receptor is connected to an Alpha-Delta fiber or a C-fiber
Which of the following structures does not receive direct input from retinal ganglion cells? a. Primary visual cortex b. The suprachiasmiatic nucleus (SCN) in the hypothalamus c. The superior colliculus in the tectum d. The lateral geniculate nucleus (LGN) in the thalamus The Glossopharyngeal nerve (cranial nerve IX) is a “mixed nerve,” meaning that it carries sensory and motor information. One of the functions of this nerve is carrying taste information from the caudal third of the tongue. The fibers that carry this information in the glossopharyngeal nerve are classified as which component type? a. Special efferent b. Special afferent c. General visceral efferent d. General somatic afferent
In the somatosensory pathway, which of the following neurons carries information from the PNS to the CNS? Group of answer choices First order neuron Third order neuron Second order neuron Specialized receptor cell
Which of the following statements best describes the axonal projection patterns of upper motoneurons located in the primary motor cortex? Upper motoneurons located in the primary motor cortex are cholinergic and their axons project directly to muscle fibres to control voluntary muscle movements. Upper motoneurons located in the primary motor cortex are glutamatergic and their axons project to the thalamus, brain stem and directly to muscle fibres to control voluntary muscle movements. Upper motoneurons located in the primary motor cortex project to the spinal cord where they synapse with cholinergic lower motoneurons that control voluntary muscle movements. Upper motoneurons located in the primary motor cortex project to neurons in the cerebellum, thalamus and brain stem that in turn contact lower motoneurons in the spinal cord to control voluntary muscle movements.
An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly withdrawn through a reflex arc. How do we sense different types of pain (very painful vs. not painful at all)? Using what you understand about threshold potentials and the all-or-none principle, explain how it is possible to sense different levels of pain. question is in bold
What does the neuron composition of the dorsal root ganglion tell you about sensory coding in the somatosensory system? a. The large axon sizes have a slower conduction velocity than small axon sizes. b. The uniform axon sizes for all neurons indicate that they have the same conduction velocity. c. Multiple modalities or sensations can be detected from the skin. d. Only a single modality or sensation can be detected from the skin. e. Processing must occur directly in the skin since the neurons in the dorsal root ganglion are second order neurons.
In complete darkness, why are there no neural signals being sent to the brain by the retinal ganglion cells? A. glutamate release from rods stimulates the retinal ganglion cells B. glutamate release from rods stimulates bipolar cells which then inhibit retinal ganglion cells C. glutamate release from rods is reduced which then fails to excite retinal ganglion cells D. glutamate release from rods inhibits the bipolar cells which then inhibit retinal ganglion cells
Which is true regarding somatotopic organization? Select one: a. Certain areas of the body have much higher representation in the primary somatosensory cortex than other areas, and these regions will have finer tactile discrimination. b. The representation of a given area of the body in the primary somatosensory cortex is directly proportional to the size of that body area (e.g., the right index finger has less representation than the right thigh). c. The receptive fields for somatosensory neurons are circular and relatively consistent in size across areas of the body, but areas of the body with the finest tactile discrimination have many more neurons representing them in the primary somatosensory cortex. d. There is equal representation of all areas of the body in the primary somatosensory cortex
What are characteristic for the ascending sensory pathways: Non-classical pathways use ventral and medial nuclei in the thalamus The thalamus in classical pathways project directly to the lateral nucleus of the amygdala. The thalamus in classical pathways project to primary sensory cortices. Non-classical pathways do not activate the autonomic nervous system.
Which of the following body regions has the greatest representation in the somatosensory cortex?
Sense of smell, also known as olfaction, is the ability to perceive and interpret odours.
