急遽出席を命ぜられてしまった全学委員会が大幅に長引いてしまい、充分なお話ができませんでしたが、ニューロンの形態が情報処理にどのように影響するかをおはなししました。
講義後、受講生に追加で紹介したYouTube動画を紹介します。
紹介した動画を作成しているのはカナダ在住のmedical studentの方で，とってもわかりやすい説明です。
- Equivalent Circuit Model Of The Neuron Explained (Capacitance, Resistance, Driving force)
- Neuron As RC Circuit Explained And Analysis of the Time Constant Tau
- Cable Theory Model of the Neuron And Analysis Of The Space Constant Lambda (With Derivations)
- Temporal And Spatial Summation In Neurons Explained (With Passive Membrane Properties)
神経細胞の電気特性の中で、活動電位の発生機構を除いた「膜の受動特性 (passive property)」に絞ってお話をしましたが、活動電位の発生機構やシナプス伝達の仕組みなどについても深く理解したい場合は、以下の動画もオススメです。
- Hodgkin-Huxley Model of Voltage-Gated Channels Explained (Gating Variables n, m, h)
- Endplate Potentials (EPPs) And Quantal Release Explained (Bernard Katz Experiments)
全体を一つにまとめた動画もありました（２時間ちょいありますが、タイムスタンプを使って途中の聞きたいところから聞き始めることも可能）
細胞レベルから神経科学をしっかり勉強したい人には、これらの動画、オススメです。
In my graduate lecture, Advanced Anatomy and Physiology, I gave a talk titled “The Physiology of Neuronal Shape and Function.”
Unfortunately, due to a university-wide committee meeting I was unexpectedly required to attend, which ran significantly over time, I couldn’t deliver the lecture as thoroughly as I had hoped. Nonetheless, I discussed how neuronal morphology influences information processing.
After the lecture, I shared additional resources with the students, including a set of highly recommended YouTube videos. These videos are created by a medical student based in Canada and offer exceptionally clear explanations:
- Equivalent Circuit Model of the Neuron Explained (Capacitance, Resistance, Driving Force)
- Neuron as RC Circuit Explained and Analysis of the Time Constant Tau
- Cable Theory Model of the Neuron and Analysis of the Space Constant Lambda (With Derivations)
- Temporal and Spatial Summation in Neurons Explained (With Passive Membrane Properties)
In my lecture, I focused on the passive electrical properties of neuronal membranes, excluding the mechanisms of action potential generation. For those who wish to delve deeper into topics such as action potential mechanisms and synaptic transmission, I also recommend the following videos:
- Hodgkin-Huxley Model of Voltage-Gated Channels Explained (Gating Variables n, m, h)
- Endplate Potentials (EPPs) and Quantal Release Explained (Bernard Katz Experiments)
Additionally, there’s a comprehensive video summarizing all these topics, titled:
- Properties of Neurons in the Central Nervous System (Neurophysiology) | Full Discussion
Although it’s over two hours long, you can use the timestamps to jump to specific sections of interest.
For anyone interested in studying neuroscience thoroughly, starting at the cellular level, I highly recommend these videos.
