Otago researchers have discovered that neural circuitry they previously showed was vital to triggering ovulation and maintaining fertility also plays a key role in moulding the male brain.
In new research appearing in the Journal of Neuroscience, a team led by Professor Allan Herbison shows that male-specific signalling in the Gonadotropin-releasing hormone (GnRH) neurons of new-born mice is crucial to generating a testosterone surge that occurs up to five hours after birth.
DARPA and Stanford Brain Imaging Collaboration helps to bring a new CLARITY to the world of Neuroscience
Thanks to a 100 million dollar grant through the White House Brain Mapping Project to the NIH, NSF, and DARPA (Defense Advanced Research Projects Agency), a dynamically new approach to how we view the brain has arisen: the CLARITY Brain Imaging Technique. With this technique, scientists are hoping to map brain connections on a large scale, visualizing how every single neuron is fired and interconnected with the other ones in the system.
Scientists from the Florida campus of The Scripps Research Institute (TSRI) have shown in animal models that brain damage caused by the loss of a single copy of a gene during very early childhood development can cause a lifetime of behavioral and intellectual problems.
The study, published this week in the Journal of Neuroscience, sheds new light on the early development of neural circuits in the cortex, the part of the brain responsible for functions such as sensory perception, planning and decision-making.
