C) physical contact between adjacent neurons. D) chemical signaling molecules released from neuroglia. chemical signaling molecules-neurotransmitters. WebNov 18, 2015 · At each synapse, a presynaptic neuron sends chemical signals to one or more postsynaptic receiving cells. In most previous studies of how these connections evolve, scientists have focused on the role of the postsynaptic neurons. However, the MIT team has found that presynaptic neurons also influence connection strength.
