QUESTION 1 3. Cortex 2, Limbic 1. Brain Stem Eigure 1 The above diagram shows the sections of the neuroanatomy of the brain. This diagram may assist you in answering the following questions, 1 through 15 of this EXAM There are three sections of the brain noted in the diagram and these sections are numbered as L Brain Stem 2. Limbic System Cortex. Neurons that enable the brain to make neurotransmitters are called somatodendrites. These somatodendrites are also called neuronal cell bodies. Select from the following neuroanatomic substrates, the section that makes the neurotransmitter, dopamine. OA Brain Stem o8 Limbic System o c. O Cortex Prefrontal Cortex

Explanation / Answer

1) Section of brain that makes dopamine - Prefrontal cortex

2) The limbic system includes all ( amygdala , nucleus accumbens , ventral striatum ) except Ventral tegmental area [VTA]. Though VTA is a dopaminergic neuronal structure and located in the midbrain , it is not included in limbic system . On the other hand , Striatum consists of 2 parts namely ventral and dorsal . Ventral striatum is a part of limbic system , so VTA is the better choice available .

3) Neuroanatomic structure that directs the process of decision - Amygdala

4) The reward pathway ( also called mesolimbic pathway ) starts with - Ventral tegmental area

5) Dopamine to te ventral tegmental area to the nucleus accumbens to the prefrontal cortex
