To gain a holistic understanding of brain neurochemical function, scalable tools that can measure neurochemistry at spatial and temporal scales commensurate to brain function are needed. Fluorescent protein-based probes have a high spatial and temporal resolution, and when coupled to genetic engineering tools, are able to target specific ...
Brain chemicals, called neurotransmitters, are packaged in tiny, bubble-like compartments known as vesicles. The images show vesicles at the end of one brain cell that are ready to cross a small gap into another brain cell.
8 Φεβ 2021 · The chemical brain hypothesis discusses how elementary nervous systems may have functioned and evolved. Some of the ideas may apply to extant nervous systems, in particular to non-bilaterians and larval bilaterians that potentially retained a richer mosaic of ancestral characters.
How can a chemical compound, unchanging in various parts of the body or brain, produce diverse results? The answer lies on the other side of the synapse in the receptor sites, which do change their properties to a surprising degree and in the end determine what effect a neurotransmitter has on a cell.
1 Οκτ 2015 · Creatine, a naturally occurring nitrogenous organic acid found in animal tissues, has been found to play key roles in the brain including buffering energy supply, improving mitochondrial efficiency, directly acting as an anti-oxidant and acting as a neuroprotectant.
Studying the Brain in Development. Short of technology that would shrink a remote video camera down to the size of a cellular implant, how can neuroscientists study brain development as an ongoing process in the living animal?
1 Μαΐ 2023 · Neurotransmitters are endogenous chemicals that allow neurons to communicate with each other throughout the body. They enable the brain to provide a variety of functions, through the process of chemical synaptic transmission.
