it's said the striatum sends inhibitory signals to the globus pallidus but the globus pallidus is a part of the striatum, should be a little more specific there
aprilneha (3 месяца назад)
globus pallidus is not part of the striatum. the striatum is the putamen and caudate

took my professor 90 mins to explain this, and i was still confused came here watched once it now it all makes sense Eureka forrrealll

Great, simple, very informative. Only one question: what stimulates Subthalamic Nucleus to send an excitatory signal to Substantia Nigra?)
Shouq Mohamed (9 месяцев назад)
this was faaaaaantastic
Triana Hardianti (9 месяцев назад)
thank you so much for this concise explanation! but could you please tell me, who order the subthalamic nuclei to excite at the 1st place? thanks!
vinestreet7 (10 месяцев назад)
Love your voice. So pleasant to listen to. Thank you.

thank you so much, this explanation was so clear. I wish she was my neuroscience lecturer loool
Ricky Storrie (11 месяцев назад)
what about dopamine?
Ahmed Gharawi (11 месяцев назад)
I love u ;)
eliska mataskova (11 месяцев назад)
why can't lecturers at uni be like this pls? they made it sound so complicated and it is actually pretty straight forward. thank you <3

great explanation
Could you please tell me what is the program used in this clip? I have to make a clip for my senior project. Any recommended programs ? Thank you:)

In this video you state that the "Thalamus" is always in inhibition. However, in your indirect pathways and your PD video. You state that the thalamus is always excited like a dog. So which is it? always in inhibition or excitation?
Matthew Enriquez (11 месяцев назад)
The thalamus is always excited like a dog by default. The globus pallidus is always keeping it inhibited tho, like an owner controlling his/her dog. That's what I got out of this, anyway.

Hello, In a resting person, the THALAMUS is under constant inhibition from the GLOBUS PALLIDUS. (To prevent it from sending a signal to the cortex thus avoiding making an unnecessary movement). When one wants to make a movement however, this inhibition is cut off. additional: the thalamus does not need an activation signal. All it needs is for the inhibition signal to be cut off, his is because, it is always ready to fire if not inhibited. (thus is why she said it is always active) I hope this helps. good luck with your studies.

What is the name of the excitatory neurotransmitter that goes from the subthalamic nucleus to the substantia nigra?  Is it Glu or Dop or something different? Also coming back is it gaba?  It would be very helpful if you included all neurotransmitters in the future. : ) LOVE your work!  I don't know if you work in connectomics much regarding the 3 types of learning in real time....(physical structure of content, history of content and real time experience of content) I think your mother type voice regulates students making it easy to learn...lol....I know it sounds crazy but I think there is some truth to this.  I found it much easier to learn from your videos....I believe I already have circuits in place that recognize the soft tone of your voice....from -9 months to 8 years old my mom had a very gentle tone as I imagine most moms do.  Anyway, the point is when we are regulated it is much easier to learn. : )

very well and evenly understandable explained. thank you! :)
Lucas Prust (3 года назад)
I thought that striatum inhibits globus pallidus (ext), that inhibits globus pallidus (int), therefore the striatum activate the global pallidus (int). Can someone explain this to me? I'm very confused now.
Neil Parikh (2 года назад)
+Lucas Prust Sorry if this is too late, but you appear to have slightly mixed up the indirect and direct pathways of the basal ganglia. The direct pathway was outlined correctly in the video; the indirect pathway DOES involve the striatum inhibiting GPe, but GPe inhibits the subthalamic nucleus (NOT GPi) which normally activates GPi indirect inhibition of GPi). This consecutive inhibition acts as an activator, and upregulates GPi inhibition of the thalamus. The overall effect of this pathway is inhibition of movement. However, D2 (dopamine 2) input to the striatum actually inhibits this pathway, leading to decreased inhibition of the thalamus (usually translating to increased movement).
