Here is a simplified flow chart for neuron transmission:

1. Neuron receives signals from other neurons or sensory receptors.
2. Signal travels down the dendrites towards the cell body.
3. Signal reaches the cell body and is integrated with other incoming signals.
4. If the combined signal is strong enough, an action potential is generated.
5. Action potential travels down the axon towards the axon terminals.
6. At the axon terminals, neurotransmitters are released into the synaptic cleft.
7. Neurotransmitters bind to receptors on the dendrites of the next neuron.
8. This binding triggers a new action potential in the next neuron.
9. The process repeats as the signal is transmitted through the neural network.

Please note that this is a simplified version of neuron transmission and there are many more complex processes involved in the functioning of neurons.

Neuron Transmission Flow Chart

Step 1: Resting State
- Neuron is inactive, maintains a negative membrane potential (-70 mV)
- Potassium (K+) ions inside, sodium (Na+) ions outside
- Sodium-potassium pump actively transports Na+ out and K+ in

Step 2: Stimulus
- A stimulus (e.g., electrical, chemical) depolarizes the neuron
- Sodium-voltage gated channels open
- Na+ ions rush into the neuron, making the membrane potential more positive

Step 3: Action Potential
- Membrane potential reaches threshold (-55 mV)
- Voltage-gated sodium channels fully open, causing a rapid influx of Na+ ions
- Membrane potential reverses (+40 mV)

Step 4: Repolarization
- Voltage-gated sodium channels close
- Potassium-voltage gated channels open
- K+ ions flow out of the neuron, making the membrane potential more negative
- Membrane potential returns to resting state

Step 5: Hyperpolarization
- Membrane potential briefly dips below resting state (-90 mV)
- Excess K+ ions are expelled by the sodium-potassium pump

Step 6: Synapse
- Action potential reaches the axon terminal
- Voltage-gated calcium channels open
- Ca2+ ions enter the terminal

Step 7: Neurotransmitter Release
- Ca2+ ions trigger the release of neurotransmitters into the synaptic cleft
- Neurotransmitters bind to receptors on the postsynaptic neuron

Step 8: Postsynaptic Response
- Neurotransmitter binding can cause either:
- Excitation: opening of sodium channels and depolarization
- Inhibition: opening of potassium channels and hyperpolarization

Step 9: Synaptic Transmission
- Electrical signal (action potential) is converted into a chemical signal (neurotransmitter release)
- Chemical signal is then converted back into an electrical signal (postsynaptic response)
