A team of engineers and neuroscientists has demonstrated for the first time that human brain organoids implanted in mice have established functional connectivity to the animals' cortex and responded to external sensory stimuli. The implanted organoids reacted to visual stimuli in the same wa
Iron (Fe) accumulates in the brain cortex with aging. A plethora of studies indicate that progressive iron accumulation in the substantia nigra (SN) in the aged human brain is a major risk factor for Parkinson's disease (PD) and other neurodegenerative diseases, but not everyone. This is bec
Neuroscientists discovered that the adult brain contains millions of 'silent synapses' immature connections between neurons that remain inactive until they're recruited to help form new memories.
Scientists at the UNC School of Medicine have mapped the surface of the cortex of the young human brain with unprecedented resolution, revealing the development of key functional regions from two months before birth to two years after.
