Defective Glial Cells Can Push Neurons Toward Parkinson's Disease
Defective Glial Cells Can Push Neurons Toward Parkinson's Disease
News   Jan 16, 2019

Scientists have discovered that defective astrocytes are linked to the buildup of a toxic protein that is one the hallmarks of Parkinson's disease. The studied astrocytes, derived from Parkinson's disease patients with a genetic mutation that affects cell clean-up functions, caused more accumulation of the toxin, α -synuclein, than those derived from healthy individuals.

Psychiatrists diagnose people with mental illnesses by spending time with them, looking for the particular behavior symptoms of each. By deciphering the circuitry of the medial frontal cortex – an area beneath the top of the head — those diagnoses could become much more efficient and precise by allowing physicians to diagnose based on how neurons respond to a simple series of behavior tests.

Three-photon microscopy recently emerged as a technique that could give neuroscientists a deeper look at brain cells than ever before. Now, based on a substantial refinement of the technology, scientists at MIT have conducted the first-ever study of stimulated neural activity in an awake mouse through every visual cortex layer and notably the mysterious “subplate” below.
