I guess I had never understood cns physiology in my med school until today I came across this masterpiece. Absolutely insane . And.compact to point. Excellent method of teaching. Lot of love from pak❤

00:12 Overview of the sensory and motor functions of the spinal cord.
02:38 Motor neurons in the ventral horns control muscle movement.
08:19 Pacinian corpuscles detect deep touch and high-frequency vibrations.
10:53 A Beta fibers transmit touch sensations and modulate pain perception.
16:06 Spinothalamic tracts carry sensory information to the brain.
18:18 Dorsal column tracks transmit advanced sensations from the body.
22:21 Dorsal column tracks handle advanced sensations in the spinal cord.
24:12 Dorsal column tracks carry advanced sensations ipsilaterally and do not cross sides.
28:29 Brown-Sequard syndrome results in sensory losses due to spinal cord hemisection.
30:41 Damage to spinal cord leads to distinct sensory disorders.
35:05 Dissociative sensory loss affects certain sensations while preserving others.
37:24 Thalamus acts as a sensory relay center with specific nuclei for sensation types.
41:33 Understanding the roles of precentral and postcentral gyri in motor and sensory functions.
43:36 Broca's and Wernicke's areas are crucial for speech production and comprehension.
48:10 Overview of the sensory regions in the brain's central cortex.
50:24 Cortex regions process sensations from different body parts.
54:14 Sensory homunculus shows brain area representation for body parts.
56:15 Sensory information pathways transmit sensations to the cortex.
1:00:21 Overview of cortical plasticity and descending motor tracts.
1:02:35 Overview of motor pathways and corticospinal tract structure.
1:06:09 Upper motor neurons originate from both motor and sensory cortex.
1:08:15 Corticospinal and extrapyramidal tracts regulate motor functions in the body.
1:12:11 Upper motor neuron lesions lead to exaggerated reflexes and paralysis.
1:14:00 Differences between motor neuron lesions and muscle proprioceptors.
1:18:05 Information from muscle spindles and motor neurons enters the central nervous system.
1:19:56 The stretch reflex is a monosynaptic reflex that protects muscles.
1:23:23 Inverse stretch reflex prevents muscle injury from excessive tension.
1:25:08 Tendon tension activates reflex inhibition to prevent muscle damage.
1:28:59 Hypothalamic nuclei regulate body temperature through cooling and warming mechanisms.
1:31:15 Suprachiasmatic nucleus regulates circadian rhythms and hunger.
1:35:44 The hypothalamus regulates sleep and wakefulness through specific nuclei.
1:38:06 Four neurotransmitters crucial for regulating wakefulness and sleep.
1:42:28 Overview of EEG Waves and Their States of Consciousness
1:44:41 Different brain wave frequencies correlate with sleep stages and memory.
1:49:00 Key sleep abnormalities include sleepwalking, bruxism, and night terrors.
1:51:11 Parasomnias occur during NREM sleep, not REM sleep.
1:55:28 The basal ganglia store and plan motor movements while inhibiting involuntary actions.
1:57:37 Key components and functions of the Basal Ganglia.
2:01:56 Parkinsonism symptoms include rigidity, bradykinesia, and resting tremors.
2:04:18 Involuntary movements include athetosis and chorea, with key differences in their characteristics.
2:08:08 Proprioception and Broca's area involve key sensory and speech functions.
2:10:03 Dorsal column involvement affects upper limb sensations and multiple sclerosis pathology.
2:14:07 Neuronal action potentials depend on resting potential, depolarization, and hyperpolarization phases.
2:16:01 The absolute refractory period prevents new action potentials from occurring.
2:19:52 Circumventricular organs regulate key physiological functions outside the blood-brain barrier.
2:21:49 Body temperature regulation involves shivering, vasoconstriction, vasodilation, and sweating.
2:25:51 Understanding the effects of nerve damage and movement disorders in CNS.

Best lecture on cns physiology, this sir is a legend he can explain many subjects in a very understandable and conceptual manner

Sir you're teaching in simplified manner appreciate it. Pls Pronounce the Key words in concise Way Thank you 🙏

Just perfect! A nightmare became so easy, lots of gratitude from across the border!

CNS physiology has been nightmare for me but not anymore bcz of you. Thanks alotttt keep uploading more videos.....❤❤❤❤❤

best lecture on CNS, thank you so much Dr

Lot of thanks 🙏🏼 for simpler explanation

Explanation is soooo good. Thank u

wish i watched this before my continuous assessment but well i have the knowledge now :face-blue-smiling:

Thank you for this video

Thanks a lot for this great video

The way you are framing each sentence.. so that we can understand easily, shows your passion towards teaching sir..
Thank you so much for providing this much valuable content for free sir.
Thanks a lot sir..🙌🏻

It's relief my fear from cns questions. Greatest video

What a great seasion this is. Thank you sir for explaning the hardest part of physio so smoothly❤

Thank you so much, sir. High praise.
The explanation, your enunciation and organization of this lecture is extraordinary.
Thank you so much.

thank you so much sirr❤
i never lerned cns like this it was amezing and usefull....

The whole semester and I am lost because of cns physiology and I came now to watch this greatness, I'm really sad because the exam is in 7 days..

I undrstood everything thnks ❤

Best revision video thank you sir ❤
