The ethical questions raised by emerging neuro-technologies Spectral-Design/Shutterstock Neuroscience is heading into an ethical minefield with the rise of research on “human brain surrogates”. That’s according to a new paper by Henry T. Greely in the American Journal of Bioethics, titled Human Brain Surrogates Research: The Onrushing Ethical Dilemma Greely defines ‘human […]

Neuronal fibers in a healthy brain (top) and a brain with agenesis of the corpus callosum (bottom). In the healthy brain, the two hemispheres are connected by the corpus callosum fibers, shown in red. These fibers are absent in the brain with corpus callosum agenesis.

Researchers provide the first physiological evidence that a foundational center of the brain influences how sound is processed, identify a previously unknown neural circuit. For the first time, researchers have provided physiological evidence that a pervasive neuromodulation system―a group of neurons that regulate the functioning of more specialized neurons―strongly influences […]

New research suggests that reading computer code does not rely on the regions of the brain that are involved in language processing. Credit: Jose-Luis Olivares, MIT Neuroscientists find that interpreting code activates a general-purpose brain network, but not language-processing centers. In some ways, learning to program a computer is similar […]

Neurons are like the electrical wiring of our bodies. They are connected by synapses, which play an important role in transferring information. Inside synapses, there are complex molecular machineries, such as synaptic vesicles (SV), that work in harmony to ensure proper neurotransmission. This research looked at the synaptic proteome — […]

A deficiency in vitamin D on the mother’s side could explain why autism spectrum disorder is three times more common in boys, say Queensland Brain Institute researchers. In their latest study, Professor Darryl Eyles and Dr. Asad Ali found vitamin D deficiency during pregnancy caused an increase in testosterone in the […]

ANIMATION Norepinephrine release to cells is diminished, causing cascade of effects. In a new paper, researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) report brain chemistry that may contribute to why drinkers have difficulty paying attention while under the influence. The work […]

Bringing neuroscience out of the laboratory and into the concert hall. We all know that moment when we’re in the car, at a concert or even sitting on our sofa and one of our favorite songs is played. It’s the one that has that reallygood chord in it, flooding your system […]

“As we age, it’s harder to have a get-up-and-go attitude toward things,” says study author Ann Graybiel. Credit: Christine Daniloff, MIT Research on mice suggests aging affects a brain circuit critical for learning to make some types of decisions. As people age, they often lose their motivation to learn new […]
