In adults some organs like the brain appear to have relatively few true stem cells. The argument has been made that the adult human brain may have no real stem cell-based regenerative capacity, in which case functionally speaking there may be no stem cells at all there. I kind of doubt t...
1. The growth of new brain cells can help with bad mood and mental diseases such as depression. 2. Learning and doing sports that can bring blood to your brain can increase new growing brain cells. 3. Stress, lack of sleep and growing older decreases growing brain cells. 4. Healthy diet...
Of 100 billion nerve cells in the human brain, how many form after birth? For years, the official answer was "zero". Scientists thought people were born with all the neurons they'd ever have. But from 1980s, biologists overturned that doctrine, finding a reservoir of stem cells that beca...
WASHINGTON, Aug. 12 (Xinhua) -- The U.S. scientists have mapped a part of the molecular machinery that helps the brain maintain long-term memories, providing new targets against Alzheimer's disease characterized by memory loss. The study published on Monday in the Proceedings of the National ...

The hippocampal cognitive map is thought to bedriven by distal visual cues and self-motion cues.However, other sensory cues also influence place cells. Hence, we measured rat hippocampal activity in virtual reality (VR), where only distal visual andnonvestibular self-motion cues provided spatial...
by Lawrence Goodman,Brandeis University Ask even the youngest schoolchild how many senses we have and she'll tell you five—sight, sound, smell, taste and touch. Neuroscientist Don Katz thinks this might be wrong. The correct answer, he says, will most likely turn out to be is one. For ...
How much of the brain do we understand? Thanks to brain imaging techniques, scientists have a much better understanding of the brain today than they did in the past. Despite these advances, there are still many aspects of the brain that researchers do not yet know. Future research will most...
