outline the neurochemical transmission and inhibition of pain. Then using the gate-control theory, devise a plan to minimize pain during your next visit to the dentist. Why is this important for you to know in public health

We know that short term habituation is due to changes in the presynaptic sensory neuron. What possible changes could explain the results of Kandel’s experiment? Which possibility currently has the most experimental support?

Which experimental technique would be most helpful in mapping the function of the cells in the primary motor cortex?     Select one: a. electrical stimulation b. cortical lesions c. Golgi stain d. intracellular recording  e. immunohstochemistry/immunocytochemistry

A study testing sensory deprivation took place at McGill University in the 1950’s. What is sensory deprivation?     A desire to persevere with work and to avoid distraction in order to reach personal goals.     A state in which there is little or no sensory stimulation.     Desires for increased stimulation.     Somebody who regularly seeks out thrilling activities such as riding mountain bikes, roller coasters, or even skydiving.

How does lidocaine cause numbness when injected? destroys pain receptors  repolarizes sensory axons blocks effectors from reaching threshold prevents voltage gated channels from opening

Which brain region involved in action control is incorrectly paired with its function?          a.  Prefrontal Cortex (PFC) - Plans and coordinates internal thoughts and external actions    b.  Cerebellum - Motor learning, monitor action online, coordinates the timing and trajectory of movement    c.  Frontal Eye Fields (FEF) - Execution of voluntary eye movements    d.  Supplementary Motor Area (SMA) - Responds to observed and self-enacted action

When a person is cognitively aroused, neurons are desynchronized in their firing as they carry out separate tasks.  True  False

The expression "can't see the forest for the trees" implies an over-reliance on the parts/details of a problem instead of considering the whole. Based on what we covered in lecture, it might also describe someone who has an overactive relative to their parietal cortex; premotor cortex left hemisphere; right hemisphere right hemisphere; left hemisphere premotor cortex; parietal cortex

What is reciprocal inhibition? How does this term relate to “good” and/or “altered” posture?

A pin can be pressed against the skin lightly and elicit no response from the pain receptor how ever, if this pain is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc. use what you know about threeshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain)
