How the brain detects a weak signal amidst all the noise

  • No comments
A study by researchers from the Hebrew University and the Max Planck Institutes shows how groups of nerve cells work together to quickly detect even very weak sensory stimuli, despite the constant electrical activity in the brain.

Researchers at Columbia University have identified more dormant stem cells and fewer young, maturing neurons in the brains of adults with major depression. The study, published in Nature Medicine, also points to widespread disruptions in brain circuits.

Researchers from the Hebrew University and University College London have developed an antioxidant therapy based on AAV vectors. The therapeutic sequence is activated in response to abnormal electrical activity in the brain. More than half of the treated rats were free of seizures, and the remaining animals

The surprising limit to human thinking speed – only 10 bits per second

  • No comments
The paradox is that sensory input processing is done at a speed 100 million times faster than the speed of thought * Principal Investigator: "At any given moment, we extract only 10 bits out of a trillion that our senses perceive and use."

New research suggests that the brain creates at least three copies of each memory. This also includes those encoded by early-formed neurons, which appear purple in a microscope cross-section of a mouse hippocampus. (Image credit: Biozentrum, University of Basel)

Common fruit bat. Weizmann Institute scientists report on a new type of neurons discovered in the bat brain. These neurons encode the direction and distance to the target to which the bat navigates and in this way they constitute a direct neural mechanism for navigating to targets.

Cut through the retina. Except for the gray engulfing layers at the bottom, all the parts are transparent and have been painted here for demonstration purposes only. The nerve cells fill the blue volume, and the cell nuclei are pink, brown and red. The light comes from the pupil of the eye (above) and is captured in the funnels of the glial cells (green) where it is concentrated to the color-sensitive cells (membranes) marked in purple. The rest of the scattered light reaches the reed cells that are not sensitive to color (in orange). The thickness of the retina is about a quarter to half a millimeter.
