Congrats for the channel. I am a psychiatrist in Brazil and I am about to launch a course called "Anatomy of emotions to lay people". There is a lot of discrimination, stigma and prejudice regarding mental disorders in my country, so the idea of the course is trying to change society point of view. I will follow you for sure. Best regards always. Primo Paganini.
That is so amazing! My names nolan. I’m 17 years old and I was correctly diagnosed with brain cancer at 4 years old. I use my story to inspire ppl through bodybuilding! U r probably the smartest YouTube guy! Thank u so much for the amazing video!
The amygdala has projections to the hypothalamus via a path named stria terminalis. So, when you're scared, your amygdala elaborates your fear and sends instructions to activate the hypothalamus too, that in turn projects to the ANS centers in the brain stem and spinal cord.
You haven't mentioned smell either, dipshit! Fckn pretentious Khan acadomy asswholes.
I apologize in advance ] for the aggressive comment but my aggression must be coming from my Amygdala. Perhaps you should just obliterate everyone's amygdala, leaving us all with hyperorality and hypersexuality.
Everyone likes to pretend to be an ANS specialist, telling us what each system does, instead of integrating it into a real human brain that incorporates these structures/functions into our every day survival.
I kept on smiling throughout the first minutes of the video. I love the Hippo-hat! I have an exam on this tomorrow and thanks to you I understand the subject completely. So thank you for sharing your knowledge in such an easy way to understand :)))
I love the diagram and the description of the component parts, but I thought you didn't really address why these parts are considered to be a 'system' at all. You just listed a lot of apparently different functions of the individual consituents.
Can I use your Hippo Hat idea? I am a life coach and I work with quite a few people that could really use some easy to understand explanation of the limbic system... as I introduce them to the topic I'd love to be able to incorporate your hippo hat with some other explanations.
Dear Jeffrey Walsh, you are excellent in teaching and I am very much helped by your teaching on the limbic system. I am actually in South Africa and don't know how to get your videos on the central system.
Pathway of the sense of smell does not bypass the thalamus. Olfactory circuits do eventually synapse with the anterior nucleus of the thalamus. One more important point is that Cingulate Gyrus should also be included as integral element of the limbic system.
Antidepressants are medications that can help relieve symptoms of depression, social anxiety disorder, anxiety disorders, seasonal affective disorder, and dysthymia, or mild chronic depression, as well as other conditions.
They aim to correct chemical imbalances of neurotransmitters in the brain that are believed to be responsible for changes in mood and behavior.
Depression Medications (Antidepressants)
These are the most commonly prescribed type of antidepressant.
Serotonin and noradrenaline reuptake inhibitors (SNRIs) are used to treat major depression, mood disorders, and possibly but less commonly attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety disorders, menopausal symptoms, fibromyalgia, and chronic neuropathic pain.
SNRIs raise levels of serotonin and norepinephrine, two neurotransmitters in the brain that play a key role in stabilizing mood.
Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants. They are effective in treating depression, and they have fewer side effects than the other antidepressants.
SSRIs block the reuptake, or absorption, of serotonin in the brain. This makes it easier for the brain cells to receive and send messages, resulting in better and more stable moods.
They are called "selective" because they mainly seem to affect serotonin, and not the other neurotransmitters.
