Analytes may include endogenous molecules (e.g. neurotransmitter, hormones, glucose, etc.) to assess their biochemical functions in the body, or exogenous compounds (e.g. pharmaceuticals) to determine their distribution within the body. The microdialysis technique requires the insertion of a small microdialysis catheter (also referred to as ...
Typically in MRS a single spectrum is acquired by averaging enough spectra over a long acquisition time. [8] Averaging is necessary because of the complex spectral structures and relatively low concentrations of many brain metabolites, which result in a low signal-to-noise ratio (SNR) in MRS of a living brain.
A neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.The cell receiving the signal, or target cell, may be another neuron, but could also be a gland or muscle cell.
Graded potentials are usually produced in the dendrites of a neuron where voltage-gated channels are not present. They are localized changes in the membrane potential in response to a stimuli, like neurotransmitters binding to receptor. This binding causes a change in conformation, which activates the receptor to interact with proteins.
In vivo magnetic resonance spectroscopy (MRS) is a specialized technique associated with magnetic resonance imaging (MRI). [1] [2]Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non-invasive, ionizing-radiation-free analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's ...
Wellbutrin prevents your brain from reabsorbing the neurotransmitters dopamine and norepinephrine. This can lessen symptoms of depression and anxiety. Because of this, Wellbutrin may also be used ...
Generally speaking, antidepressants help balance the neurotransmitters in the brain, so when you stop taking them, your system needs time to balance itself out again.
Molecular neuroscience is a branch of neuroscience that observes concepts in molecular biology applied to the nervous systems of animals. The scope of this subject covers topics such as molecular neuroanatomy, mechanisms of molecular signaling in the nervous system, the effects of genetics and epigenetics on neuronal development, and the molecular basis for neuroplasticity and ...
