Video transcript

Hey, everyone. Let's take a look at this question together which of the following is characterized by having a small almond shaped structure within the brain's temporal lobe and is a key player in emotional processing. Is it answer choice? A the hypothalamus, answer choice B the Amygdala answer choice C the thalamus or answer choice D broke his area. Let's work this problem out together to try to figure out which of the following answer choices is the name for the small almond shaped structure within the brain's temporal lobe that is key in emotional processing. So in order to solve this question, we have to recall, what is the small almond shaped structure within the brain's temporal lobe that is a key player in emotional processing. And when we say emotional processing, we are talking specifically about the rapid evaluation of stimuli for their emotional significance. And this structure is crucial for the generation of emotional responses and the formation of emotional memories of which the name for that small almond shaped structure is the Amygdala. So answer choice B, Amygdala is the correct answer. And all other answer choices are incorrect. Since both answer choice A the hypothalamus and answer choice C the thalamus are not almond shaped or involved in emotional processing and answer choice. D the brokers area is also not located in the temporal lobe or responsible for emotional processing. So answer choice B is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
