Document Summary

Thinking about psychological events from a pharmacological perspective: pharmacology can affect psychology and vice versa, cognitive therapy and pharmacology act on the same brain -> both can lead to structural changes in the brain, neurons. When the charge is sufficiently positive, an action potential is triggered. Signal is received by the dendrites of the neuron and travels down the axon where the signal is sent to dendrites of the next neuron. Action potential single units of activity that are all or none. ~100 billion neurons in the brain and ~0. 15 quadrillion synapses in the cortex: receptors. Neurons have a cell membrane that acts like a wall preventing things from entering or leaving the neuron. Cell wall has two layers with the fatty insides (hydrophobic) of each layer sticking together like a sandwich -> fluids and other chemicals (eg. neurotransmitters) cannot pass through the layers due to the fatty insides.
