Electroencephalography | EEG waves | CNS Physiology mbbs 1st year lecture

Physiology lecture on central nervous system physiology details the fundamentals of electroencephalography (EEG) recording with EEG waves in wakefulness and various stages of sleep. EEG waves or brain waves broadly are categorized as alpha, beta, theta and delta waves and they vary in amplitude and frequency.

[@abhinashsharma3456]

ma'am , though totally unrelated to the topic , I have confusion regarding venous pressure . You are the teacher I reach out for when anything confuses me and you never disappoint . In Guyton and hall textbook medical physiology , It is stated that the blood pressure in neck veins is 0 mm hg probably relative to atmospheric pressure and -ve pressure on dural sinuses , then why isn't the venous blood sucked up instead of reaching down to right atrium . And it is also stated because of this during brain surgery when cranium is opened there is chance of atmospheric air getting sucked in leading to embolism . I am not getting a single thing about this .

[@PhysiologyOpen]

Sorry for late reply...but I searched , searched and searched. Nowhere it is mentioned that they have negative pressure Only I think during neurosurgery the pressure can become negative when the hard walks are suddenly opened , that too in certain positions Is it speciafically written in Guyton that they always have negative pressure?

[@THETBONE]

blood flows from areas where TOTAL PRESSURE (TP) is high to areas with low TOTAL PRESSURE (TP). the blood pressure readings are not the total pressure they are just a part of it which is given by Bernoulli's equation. TP = F/A + pgh + 1/2pv^2 . the blood pressure readings is the F/A component, and we should also consider the pgh component where p=density, g=acceleration due to gravity and h = height, as the blood in the neck is higher than right atrium, this pgh component is bigger and more positive for the neck and so the total pressure is actually greater in the neck than the right atrium. Again the blood pressure readings are just part of the total pressure not all. another example is that blood pressure is greater in the feet than in the aorta but blood still flows from the aorta of the arteries in the feet this is because again total pressure is higher at the aorta than the feet as the aorta (due to the larger pgh component). anyways i recommend watching videos on Bernoulli's equation as its not a straightforward concept.

Thank you so much for the video ma'am. Can you please explain the applications of Laplace law in Physiology.

Thank you for the suggestion . Will love to work on that video. I will really appreciate if I come to know more topics like that

[@chaimaasalhi9646]

How can we explain the paradoxical sleep ? Can we say that the high activity of the brain in this stage is because of dreams (since in this phase we start dreaming )

[@PhysiologyOpen]

Or is it because of the high activity that we dream...can’t pin point that...but yes neural activity is similar to awake state..many things are not known

[@chaimaasalhi9646]

@@PhysiologyOpen But surely it has relation with dreams . Thank you so much for this video it is really helpful 👏

[@PhysiologyOpen]

My pleasure as always 😊

[@chaimaasalhi9646]

@@PhysiologyOpen Another question please , can we say simply that synchronized waves like delta waves indicate low activity of the brain , while disynchronized waves indicate high activity of the brain ?

[@PhysiologyOpen]

Better to say...synchronised is sleep and desynchronised is awake like...by the way it’s sensations and their inputs to thalamus which cause synchronisation/desynchronisation (known as thalamostriatal projections) For initiation of sleep, we want less sensations- like switching of lights, minimum sound, comfy bed..decreases projections to thalamus ..and then synchronisation of waves
