PSY344H5 Lecture Notes - Lecture 5: B Cell, Pyramidal Cell
Document Summary
Know a lot of molecular part and neurochemical and how it behavior manifests but not sure of the relation studied the hippo in particular ca1. The signal that gets transmitted is all or none but the probability of the signal going out is due to the strength of connection- the stronger the connection the more likely. This happens at the synaptic level- a synapse can become potentiated (stronger) after certain events. When the synapse strengthens and the pyramidal cell fires it will activate the subsequent neurons. Tissue slice chamber- need to keep it alive- neurons don"t know they are out of a living animal- glucose for food, oxygenated, and csf- can keep tissue alive for weeks. Stimulating electrode in neuron a and recording electrode in neuron b. Cell would go from -65 to -10 (epsp)
