Abstractl-Glutamate is the most abundant of a group of endogenous amino acids in the mammalian central nervous system which presumably function as excitatory neurotransmitters and under abnormal conditions may behave as neurotoxins. As neurotransmitters, these compounds are thought to play an important role in functions of learning and memory. As neurotoxins, they are believed to be involved in the pathogenesis of a variety of neurodegenerative disorders in which cognition is impaired. Moreover…

In order to extend knowledge concerning exact functions of selected neurotransmitters and neuromodulators in the studied brain structure, the future studies should concentrate on potential alterations in the neurochemical profile during various pathological states which affect the anterior thalamic nuclei.
Current approaches to enhance glutamate transporter function and expression
- BiologyJournal of neurochemistry

Early in the disease evidence of glutamatergic neurone loss is provided by the finding that in many regions of the cerebral cortex the Na+‐dependent uptake of D‐[3H]aspartic acid was almost always lowest in AD subjects compared with control when assessed by a method designed to minimise artifacts and epiphenomena.
