Document Summary

Made up of the amygdala and hippocampus: frontal lobe: directing/maintaining attention. What are the 2 types of synapse: excitatory synapse: activated when a terminal button releases a transmitter substance that excites the post synaptic neurons on the other side of the synapse. More likely the post synaptic neuron will fire: inhibitory synapse: lower the likelihood that the axons of the post synaptic neuron will fire when they"re activated. Small potentials (voltages) generated at the post synaptic membrane by the action of neuro transmitters that make the post synaptic neuron more likely (excitatory) or less likely (inhibitory) to generate an action potential at the cell body. Glutamate: primary excitatory neurotransmitter in the brain. Gamma-amino butyric (gaba): primary inhibitory neurotransmitter in the brain. Regulates emotions, pain perceptions, and stress responses. Opioids: bind to the same post synaptic receptors as opium and morphine, body able to cope with more pain. Does so by changing the nature of neurotransmitter activity at the synapse.
