How Does a Neuron Decide to Fire? | Neurobiology Module 1 Part 7 🧠⚖️
🧠⚖️ How does a neuron decide whether to fire an action potential?
In this episode, we explore the neuron's decision-making process and uncover why not every signal becomes an action potential. Learn how excitatory and inhibitory inputs compete, how EPSPs and IPSPs influence membrane potential, and how the Axon Initial Segment (AIS) acts as the neuron's trigger zone.
00:00 Intro
00:45 EPSP and IPSP
02:05 EPSP Signalling
05:37 IPSP Signalling
09:33 Temporal vs Spatial Summation
16:14 Outro & Ion Channels?
By the end of this video, you'll understand how neurons integrate thousands of incoming signals and make the crucial decision to fire—or stay silent.
