UCLA’s Dr. Michael Fanselow: Understanding post-traumatic stress and how to treat it

Michael Fanselow is a Distinguished Professor of Behavioral Neuroscience at UCLA and Director of Staglin Family Music Festival Center for Brain and Behavioral Health at UCLA. Fanselow’s research through the Center focuses on uncovering the neurobiological bases for anxiety disorders such as post-traumatic stress. Specifically, Fanselow has studied why humans overgeneralize fear, which causes individuals to Read more

Thousands of branches and branchlets emanate from an astrocyte’s cell body, which is the dense portion in the middle of the image.

UCLA researchers reveal that astrocytes, a type of brain cell that supports and protects neurons, aren’t all the same. Baljit Khakh, a UCLA professor of physiology and neurobiology and the study’s senior author, has upended a long-standing idea in neuroscience that all astrocytes are indistinguishable. The astrocyte has several unique functions in the brain and impaired astrocyte function has been implicated in diseases Read more

People missing genetic material along the 22nd chromosome are at higher risk for schizophrenia, while those with excess genetic material there were more at risk for autism.

UCLA researchers recently discovered how certain neuropsychiatric disorders, like schizophrenia and autism, are related to brain irregularities and genetic abnormalities. Carrie Bearden, lead author of the study and professor of psychiatry and biobehavioral sciences and of psychology at UCLA, explains that duplications found in sections of chromosome 22 can sometimes lead to autism, whereas missing genetic material Read more

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
