Researchers Restore Sight in Blind Rodents

A team of neuroscientists and bioengineers from MIT’s Department of Brain and Cognitive Sciences and Center for Biomedical Engineering have been able to partially restore the vision of rodents whose visual neural pathways had been severed by injecting them with a tiny, biodegradable substrate on which brain cells were able to regrow and reconnect. The …

Synchronized Neurons Focus Attention

According to a study published recently in Nature, neurons firing synchronously help to focus the brain’s attention on certain tasks and lead to quicker response times. When neurons fire independently their electrical output is nothing but noise, and no coherent signal is discernible in the static. When even a few neurons fire synchronously, their individual …

Backwards Instant Replay Helps Rats Learn

Rat

Neuroscientists from the Picower Institute for Learning and Memory at MIT have discovered that after completing a task, a rat’s brain will mentally replay recent events, but in reverse order. They believe this process plays a key role in learning and memory and may explain why taking frequent breaks when studying is more effective for …

Neuron Growth Occurs in Adult Brains

Neurons

Researchers from the Picower Institute for Learning and Memory at MIT have recently found that contrary to popular belief, neurons do grow in mature brains. It had been widely accepted that structural remodeling of neurons does not occur in adult brains, but the discovery that it does could lead to advances in treatments of spinal …

Retrograde Signal Strengthens Synapses

Researchers from MIT studying brain plasticity, the reorganization of brain cells and their connections over time, have recently discovered a “backtalk” or retrograde signal from post-synaptic to pre-synaptic neurons that plays a crucial role in synapse development. It has long been known that synaptic strength, the strength of the connections between neurons, plays a central …

Robot Snail Conquers Walls and Ceilings

MIT's Snail Robot

Nature.com is reporting today that researchers from MIT have created a robotic snail capable of climbing vertical walls and traveling upside down across ceilings. The team, led by Anette Hosoi, developed the mechanical slug primarily to study the locomotive mechanisms of biological snails, although they believe the results of their research will eventually end up …

Intelligent Prosthetics: The Rheo Knee

Rheo Knee

Hugh Herr, director of MIT’s Biomechatronics Group, has created the Rheo Knee, an artificial knee with an integrated microprocessor that both learns the user’s walking style and is able to quickly react and adapt to changes in terrain. The microprocessor calculates the position of the knee and the load on the limb 1000 times per …
