The synapse (article) | Human biology | Khan Academy
How neurons communicate with each other at synapses. Chemical vs. electrical synapses.
Synapse structure (video) | Khan Academy
This video discusses synapses, where neurons communicate with target cells. It differentiates between two types of synapses: chemical and electrical. It also explains the role of the …
Neuronal synapses (chemical) (video) | Khan Academy
There actually are certain neurons where there isn't any gap--electrical synapses connect directly because electrical signals cannot travel through a gap. Chemical synapses need the synaptic …
The synapse (article) | Human biology | Khan Academy
A single axon can have multiple branches, allowing it to make synapses on various postsynaptic cells. Similarly, a single neuron can receive thousands of synaptic inputs from many different …
La synapse (leçon) | Influx nerveux | Khan Academy
La plupart des synapses sont dites chimiques, car les neurones communiquent à l'aide de messagers chimiques. Il existe des synapses électriques, où les ions circulent directement …
Signal propagation: The movement of signals between neurons
Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more …

La plupart des synapses sont dites chimiques, car les neurones communiquent à l'aide de messagers chimiques. Il existe des synapses électriques, où les ions circulent directement …
Neurotransmitters and receptors (article) | Khan Academy
In the article on synapses, we discussed how synaptic transmission works. Here, we’ll focus on neurotransmitters, the chemical messengers released from neurons at synapses so that they …
Synapses neuronales chimiques (vidéo) | Khan Academy
alors on commence à être familier avec le neurone et la nature des signaux qui circulent en effet on a vu qu au niveau des dendrite le neurone pouvait recevoir différents stimuli excitateur par …
