Dynamic L-Glutamate Signaling In The Prefrontal Cortex And The Effects Of Methylphenidate Treatment, Catherine Elizabeth Mattinson

Theses and Dissertations--Neuroscience

The prefrontal cortex (PFC) is an area of the brain that is critically important for learning, memory, organization, and integration, and PFC dysfunction has been associated with pathologies including Alzheimer’s disease, schizophrenia, and drug addiction. However, there exists a paucity of information regarding neurochemical signaling in the distinct sub-regions of the PFC, particularly the medial prefrontal cortex (mPFC). The mPFC receives glutamatergic input from a number of brain areas, and functional glutamate signaling is essential for normal cognitive processes. To further understand glutamate neurotransmission, in vivo measurements of glutamate were performed in the cingulate cortex, prelimbic cortex, and infralimbic cortex …
