Their function in primitive systems was intimately associated with photon capture and photosynthesis initiation. Many alkaloid drugs, including some of the most powerful hallucinogens known to man are derived from these aromatic chemicals and served as important antioxidants in plants. The loss of the ...
The researchers did not observe any signs of consciousness in the brains, nor were they trying to; on the contrary, the researchers injected pig brains with chemicals that mimicked blood flow and also blocked neurons from firing. The researchers emphasized that they did not bring the pig brains...

Glial cells are located between neurons and help support their activity. Microglial cells are part of the immune system within brain tissue, helping clear dead cells and other debris. Astrocytes help clear neurotransmitter chemicals so that the synapse can be ready to react to the next signal that...

Brains control behavior either by activating muscles, or by causing secretion of chemicals such as hormones. Even single-celled organisms may be capable of extracting information from the environment and acting in response to it. Sponges, which lack a central nervous system, are capable of ...
The three RXR isoforms show tissue-specific expression, while their functions are partially overlapped. RXRα is predominantly expressed in metabolically active systems, such as liver, muscle, lung, kidney, and heart; RXRβ is ubiquitously expressed; whereas RXRγ is abundantly expressed in brain and...
The reunion also alleviated the pups’stressresponses, measured by whether they made crying-like sounds and released corticosterone. Finally, the team wanted to see if artificially activating the neurons while the pups were isolated could alleviate their distress. Using chemicals to activate ...
