Which of the following pairings is FALSE? Question 34 options: Merkel cells = sensation of general sense of "touch" across most of the skin E Lamellated (Pacinian) corpuscles = sensation of heavy pressure, vibration Tactile (Meissner's) corpuscles = delication sense of touch (finger tips) Baroreceptors sensation of fullness (stomach) All are correct pairings
Intro to Neuro Question Dopamine input from the substantia nigra to the striatum results in which of the following? increased firing of thalamus neurons decreased firing of thalamus neurons increased firing of globus pallidus internal neurons decreased firing of globus pallidus internal neurons increased firing of globus pallidus external neurons decreased firing of globus pallidus external neurons Group of answer choices I, III and V I, IV and V II, III and V I, IV, and VI Is my reasoning correct? Dopamine from the substantia nigra: Excites the direct pathway in the striatum, leading to decreased activity in the globus pallidus internal (GPi) and increased activity in the thalamus. Inhibits the indirect pathway in the striatum, resulting in decreased activity in the globus pallidus external (GPe) and further decreasing GPi activity, which also increases thalamic activity. So, the effects are: Increased firing of thalamus neurons. Decreased firing of globus pallidus internal…

The ability to produce an emotional smile. Both their descending pyramidal and extrapyramidal projections from motor cortex and brainstem. All of the above none of the above
Intro to Neuroscience Question Explain your reasoning and why you chose that answer.: Which of the following does NOT accurately describe medium spiny neurons (MSNs)? Group of answer choices They make a small number of synapses with many GPNs and a large number of synapses with a few GPNs They are GABAergic and therefore inhibitory. They are constitutively active to tonically inhibit the thalamus. They are activated by inputs from the cortex. All of the above are true

Intro to Neuro Question: The striatum has an (excitatory/inhibitory) connection to the globus pallidus external. Activation of that connection (increases/decreases) activity in the globus pallidus internal, ultimately (promoting/suppressing) movement.Group of answer choicesExcitatory, increases, promotingExcitatory, increases, suppressingInhibitory, decreases, promotingInhibitory, decreases, suppressingInhibitory, increases, suppressing Is my reasoning correct? The striatum has an inhibitory connection to the globus pallidus external (GPe). Activation of that connection decreases activity in the globus pallidus internal (GPi), ultimately promoting movement. Thus, the correct group of answer choices is: Inhibitory, decreases, promoting
