15 Απρ 2014 · Each serves a purpose to help us cope with various situations – whether it is to help us process and learn new information or help us calm down after a long stressful day. The five brain waves in order of highest frequency to lowest are as follows: gamma, beta, alpha, theta, and delta.
12 Μαρ 2014 · Opsins are proteins that change their shape in response to light of certain wavelengths. Rhodopsin, found in rod cells, responds most strongly to light in the blue-green spectrum. Three different...
Neural oscillation, synchronized rhythmic patterns of electrical activity produced by neurons in the brain, spinal cord, and autonomic nervous system. Oscillations in the brain typically reflect competition between excitation and inhibition. Learn more about the types, hierarchy, and mechanisms of neural oscillations.
22 Δεκ 2023 · Brain wave patterns are used a lot to monitor sleep stages. When we fall asleep we go from drowsy, light attention that’s easily roused (alpha), to being relaxed and no longer alert (theta),...
23 Οκτ 2015 · Called optogenetics, this technology is shining new light on how the brain works. A combination of physics, biology and engineering lets scientists use light to trigger actions by specific brain cells.
The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors.
