Question
Chapter 42.4, Problem 3EQ
Summary Introduction
To determine: An experiment to test the hypothesis that acetylcholine is Loewi’s proposed vaghusstoff, using a heart (without its vagus nerve), some acetylcholine, and an acetylcholine receptor blocker.
Introduction: Otto Loewi, a German physiologist, through his experiments, showed that there is some non-electrical entity that is released into the surrounding of the electrically excited heart that results in the desired action on the heart muscles. Experimental studies by Loewi opened the doors for chemical neurotransmitter studies.

How can an emotional stimulus reach the amygdala directly? A.From the cerebellum B.Through the lateral hypothalamus C.From the dorso-medial thalamus B.From the Central gray (PAG)arrow_forwardDear Expert. Thank you for your advice, which is good and helpful. I note that your answer is "when 3 binding sites have been occupied the activity of these receptors is maximum." However, I also note that for a similar question (see below) on α7 nicotinic Acetylcholine Receptor (nAChR) also gives the same answer, ie. at least 3 agonist binding sites should be occupied. Another Question - "To maximize the activity of an α7 nAChR, how many agonist binding sites should be occupied." I understand that in α7 nAChR, binding to two sites is more effective and binding to three sites is most effective for activation. On the other hand, binding to four or five sites in the nAChRs of chromosome 7 speeds up desensitization more than activation. Therefore, to maximize the activity of an α7 nicotinic Acetylcholine Receptor (nAChR) is also "3 sites". Am I right?arrow_forward

- 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, promotingarrow_forwardTranscranial magnetic stimulation Select one: a. is used to correlate brain activity with behaviour b. measures large changes in voltage from cortical neurons c. monitors molecular binding within the brain's tissues of molecules d. can activate or inactivate specific brain regions e. has the highest spatial resolutionarrow_forwardPlease ASAP.
