The left and right side of the brain are involved in different tasks. This functional lateralization and associated brain asymmetry are well documented in humans, but little is known about brain asymmetry in our closest living relatives, the great apes. Using endocasts (imprints of the brain on cranial bones), scientists now challenge the long-held notion […]
Knowing thy self…
Interoception is the awareness of our physiological states; it’s how animals and humans know they’re hungry or thirsty, and how they know when they’ve had enough to eat or drink. But precisely how the brain estimates the state of the body and reacts to it remains unclear. In a paper published in the journal Neuron, […]
What does this mean for the EEG’s ability to reflect consciousness? “The study does support the possibility that certain EEG features might not always accurately capture the level of consciousness in surgical patients,” says senior author George A. Mashour, M.D., Ph.D., chair of the U-M Department of Anesthesiology. However, “EEG likely does have value in […]
Drawing an object and naming it engages the brain in similar ways, according to research recently published in JNeurosci. The finding demonstrates the importance of the visual processing system for producing drawings of an object. In a study by Fan et al., healthy adults performed two tasks while the researchers recorded brain activity using functional […]
Moving… Thinking of moving… Standing still!
Brain-computer interfaces (BCI) work on the principle that measurable changes in electrical brain activity occur just by thinking about performing a task. Signals can be read, evaluated, and then converted into control signals via a machine learning system, which can then be used to operate a computer or a prosthesis. In a recently published study, […]
