UCLA researchers discover that internet searching triggers key brain areas that control complex reasoning, among middle-aged and older adults. Gary Small, professor at the Semel Institute for Neuroscience and Human Behavior at UCLA and principal investigator, reports that searching the internet may promote healthy brain function during aging. In the study, one group of the participants had no search engine experience, while the other group had some search engine experience. Read more

In his famous experiment, Russian scientist Ivan Pavlov rang a bell each time he fed his dogs. Soon, the dogs began drooling in anticipation when they heard the bell, even before food appeared.

UCLA researchers have discovered the neural mechanisms behind the Pavlovian response, which is when an individual associates a sensory cue with a reward. Sotiris Masmanidis, the study’s senior author and assistant professor of neurobiology at the David Geffen School of Medicine at UCLA, explains that the Pavlovian response is Read more

In these images of children’s brains, red correlates with slower brain signaling speeds, while green and blue indicate normal brain signaling.

Among children with moderate to severe traumatic brain injury, some experience long-term brain degeneration following injury. However, not all children that experience traumatic brain injury (TBI) have progressive cognitive decline, and CT scans do not reliably predict the likelihood for recovery. UCLA researchers discovered a biomarker Read more

UCLA scientists discovered that dendrites (shown here in green) are not just passive conduits for electrical currents between neurons.

UCLA Researchers are reframing how we understand the brain. Previously, the scientific community believed that our neurons (brain cells) have somas (neuronal cell bodies) that send electrical pulses to other neurons using branching dendrites. However, Mayank Mehta, UCLA neurophysicist and senior author, discovered that Read more
