Scientists have created a machine that lets you control your dreams. Dubbed Dormio, the device exploits a semi-lucid stage of sleep known as Hypnagogia. This stage takes place in the moment between sleep and wakefulness, and it's the period in which you're more likely to remember your dreams. Scientists hope that allowing people to control their dreams in a semi-lucid state will help spark creative thought. Scientists have created a machine that lets you control your dreams. The device is the work of Adam Horowitz and his colleagues at the MIT Media Lab.

Researchers from the Kuhl Lab at the University of Oregon explored how faces could be decoded from neural activity in the study Reconstructing Perceived and Retrieved Faces from Activity Patterns in Lateral Parietal Cortex, published in the Journal of Neuroscience. Hongmi Lee and Brice A. Kuhl tested whether faces could be reconstructed from the'angular gyrus' (ANG) located in the upper back area of the brain through functional magnetic resonance imaging (fMRI) activity patterns. They conducted the experiment by making facial reconstructions based on brainwave patterns from participants, initially during their perception of faces and later just from memory. Participants were shown more than 1,000 color photos of different faces, one after another, while an fMRI scan recorded their neural responses. The researchers then applied principal component analysis (PCA) to generate 300 'eigenfaces' - a set of vectors used in human face recognition.
