What is a Synapse?

Alie Astrocyte introduces the concept of synapses, explaining how neurons communicate through electrical and chemical synapses. Electrical synapses allow fast signaling via direct ionic current transfer, while chemical synapses use neurotransmitters to relay messages. The video details the roles of excitatory and inhibitory synapses, highlighting glutamate and GABA neurotransmitters. The importance of synapses in brain function is emphasized, and viewers are encouraged to explore further neuroanatomy topics in upcoming episodes.

What happens to the vesicles in the presynaptic terminal when a signal arrives?

How do GABA receptors affect the firing of a neuron?

Why is it important for the brain to have both excitatory and inhibitory signals?
