1 day ago · Dopamine also functions as a neurotransmitter —primarily by inhibiting the transmission of nerve impulses—in the substantia nigra, basal ganglia, and corpus striatum of the brain. A deficiency of dopamine associated with cellular death in the substantia nigra results in Parkinson disease.

1 day ago · The fly brain with a few neurons from its connectome. The ‘AI-powered lens’ reveal their neurotransmitter classes: excitatory cholinergic neurons in yellow, inhibitory GABAergic neurons in blue, and glutamatergic neurons in green. Over recent years, neuroscientists have been building brain ‘connectomes’ – maps in which all neurons and ...
1 day ago · With the new capabilities to concurrently visualize and quantify multiparametric metabolite and neurotransmitter changes at millimeter-level resolutions, we expect our technology to provide more molecular-level insights into brain disorders such as neurological and neurodegenerative diseases, and to potentially improve disease diagnosis and ...
1 day ago · The core advance of the study involved biophysically modeling what happens when ketamine blocks the “NMDA” receptors in the brain’s cortex—the outer layer where key functions such as sensory processing and cognition take place. Blocking the NMDA receptors modulates the release of excitatory neurotransmitter glutamate.
1 day ago · These transporters collectively regulate neurotransmitter concentrations at synapses and maintain neurotransmitter balance in the body. The noradrenaline transporter, also known as the ...
17 hours ago · Glutamate is the main excitatory neurotransmitter in the CNS and the ENS, both systems producing their endogenous glutamate and being preserved from luminal glutamate by a blood barrier 10. Vagal ...
