WebSerotonin is a neurotransmitter released in some synapses in the brain. it is transported back out of the synaptic gap by a transport protein in the pre-synaptic membrane. Serotonin diffuses across the synaptic gap and binds to receptors on the post-synaptic membrane. Describe how this causes depolarisation of the post-synaptic membrane. [2 marks] corvus bag
