In this paper the author will analyze how neuro processes affect behavior and impact the field of biological psychology. The author will also address the role of excitatory and inhibitory postsynaptic potentials, synaptic transmission, and receptors in producing and regulatory behavior.

Biology is changed by psychology. The development of techniques which allow scientist to monitor the brain and it functions allows it to be possible to have a much clearer understanding of how the brain works. Post translational modification, which is a type of modification of proteins that has been shown to respond in many cell types during periods of psychological depression or elation. It has been pointed out by scientist that hormones have as much a role in the activity of the mind and of the whole body. Brain mapping produces visual images of a person’s brain and the areas that show increase electrical currents and areas receiving increased oxygen being used. This shows what part of the brain is being used during a certain task when performed.

Synapses are junctions between the terminal buttons at the ends of the axonal branches of one neuron and the membrane of another (Carlson, 2007). At a synapse, a neuron releases a chemical known as a neurotransmitter that excites or inhibits another cell (Kalat, 2004). Synapses can occur in one of three places: on dendrites, on the soma, and on other axons. It's a form of communication between neurons. The messages are carried by neurotransmitters and then released be terminal buttons. Synapses are very critical for almost all aspects of behavior.

Postsynaptic potentials can either be depolarizing (excitatory) or hyperpolarizing (inhibitory); note that the neurotransmitter does not determine the nature of this potential, but instead the type of ion channel they open (Carlson, 2007). There are four...
