Neuroscience Final Exam Notes

Molecular Signaling Within Neurons:

 Electrical and chemical signaling mechanisms allow one nerve cell to receive and transmit information to

another

 Intracellular processing/signaling typically begins when extracellular chemical signals (e.g. neurotransmitters,

hormones, trophic factors) bind to specific receptors located either on the surface or within the cytoplasm or

nucleus of the target cells

o Binding activates the receptors and stimulates casca...
