Specific parts — moieties — of an agonist molecule bind to the receptor protein, causing the receptor to change shape, which in turn initiates a signaling pathway inside the cell. Some agonists are better at causing the receptor to change to its "optimal shape" for relaying signal. These are called "full agonists". Other agonists cause a partial change in ...

Why should the action potential in Axon B traverse the distance X1 to X2 more quickly than in Axon A? The larger the diameter of the axon, the less the longitudinal resistance, so the current can propagate along the axon more easily. Shouldn't the increased capacitance of Axon B (due to its increased diameter) increase the time it takes for the action ...

Restarting electrical activity would mean that at least parts of the brain become active again and possibly restoration of almost all cognitive functions. While this would be a tremendous scientific and medical break-through, it would also mean that effectively locked-in syndrome would have been induced for these pig brains. Therefore just attempting to ...

Neuropeptides are packaged in the soma via the Golgi into dense core vesicles, similar to how other types of secreted proteins are packaged. These vesicles are transported to axon terminals where they await release signals. Sossin, W. S., Fisher, J. M., & Scheller, R. H. (1989). Cellular and molecular biology of neuropeptide processing and packaging. ...

given a pen you can trace a line anywhere on your body. This is becasue humans have Proprioception. we can sense the movement of our muscles, tendons, and joints and track the location of every element of our body. Using this we can control our body precisely without other sensory input. It takes time to completely master this but most people have done so ...
