Neurobiological Bases of Behavior
Refractory period of cardiac muscle cardiac muscle has refractory period, preventing restimulation cardiac muscle has refractory period, preventing restimulation.
Local Control
Organization of the Nervous System and the Neuron.
“Nerve Impulses”. Membrane potential – + outside, - inside Caused b/c slightly more positive ions (Na + ) outside the membrane than inside (K + ) Polarized.
Types of Neurons. The Neuron The Cell Membrane Inside the Neuron.
