PSY290H1 Lecture Notes - Tryptophan, Somatic Nervous System, Monoamine Neurotransmitter
Document Summary
Neurons functional unit of the nervous system. Learn basics abut physiological properties of the neuron. With each other by generating ap and how travel down axon and how captured by post synaptic neuron. What type of nts are found in the system. Remember is voltage difference exist across membrane voltage differes inside and outside the cell and this difference is membrane potential and can be measured microelectrode tiny glass needle into the cell. As poke inside neuron can detect the difference this is moment enter cell and poke inside can pick up difference. Membrane potential of neuron when at rest. Around -70mv depending what type of neuron may differ and when see and detect voltage. Inside is neg respect to outside difference membrane of neuron is polarized. Na con is greater outside then inside by 10times. All negat ions are balanced with positive chard (switched on slide) All neutralized and balanced how can trigger voltage difference.
