The bizarre-looking ‘homunculus’ is one of neuroscience’s most fundamental diagrams. Found in countless textbooks, it depicts a deformed constellation of body parts mapped onto a narrow strip of the ...

Enhancing prefrontal cortex (PFC) cognitive functions requires identifying suitable exercises that increase cerebral blood flow. A recent study using functional near-infrared spectroscopy found that ...

In a novel set of experiments with mice trained to do a sequence of movements and "change course" at the spur of the moment, Johns Hopkins scientists report they have identified areas of the animals' ...
