A Pap test, also called a Pap smear, is an exam a doctor uses to test for cervical cancer in women. It can also reveal changes in your cervical cells that may turn into cancer later.
Neurotransmitters A Neuron is a specialized nerve cell that receives, processes, and transmits information to other cells in the body. We have a fixed number of neurons, which means they do not regenerate.
Use of this technology has led to a better understanding of which brain regions regulate mood and how other functions, such as memory, may be affected by depression. Areas that play a significant role in depression are the amygdala, the thalamus, and the hippocampus (see Figure 1).nd they are a component of brain function that we can often influence to good ends. Neurotransmitters are chemicals that relay messages from neuron to neuron. An antidepressant medication tends to increase the concentration of these substances in the spaces between neurons (the synapses).
