Developmental disorders should be viewed as continuum
Intellectual disability, autism, epilepsy and schizophrenia should be considered part of a spectrum of developmental brain dysfunction, says David Ledbetter.

The visual system’s lingering mystery: Connecting neural activity and perception
Figuring out how the brain uses information from visual neurons may require new tools. I asked 10 neuroscientists what experimental and conceptual methods they think we’re missing.
