Cellular Communication: Tools to Study Synapses

Electrical and chemical information is transmitted between neurons at asymmetric intercellular junctions called synapses. The human brain contains 86 billion neurons and within the neocortex each neuron has on average 7000 synapses1,2. Development and maintenance of synaptic connections are regulated by complex molecular mechanisms and are influenced by experience and learning3,4.

New Window of Opportunity to Prevent Cardiovascular & Cerebrovascular Diseases

Neuroimaging tests can reveal brain changes resulting from vascular disease risk factors before the appearance of any signs or symptoms of cardiovascular or cerebrovascular disease.

Future prevention and treatment strategies for vascular diseases may lie in the evaluation of early brain imaging tests long before heart attacks or strokes occur, according to a systematic review conducted by a team of cardiologists, neuroscientists, and psychiatrists from Icahn School of Medicine at Mount Sinai and published in the October issue of JACC Cardiovascular Imaging.

Brain simulation raises questions

What does it mean to simulate the human brain? Why is it important to do so? And is it even possible to simulate the brain separately from the body it exists in? These questions are discussed in a new paper published in the scientific journal Neuron October 22.
