When community is as important as the science: Olúmídé Fagboyegun
In his short, prolific neuroscience career, Olúmídé Fagboyegun has always sought community. It’s served him well, from his years at community college in Maryland to his PhD work in the Stevens Lab at Boston Children’s Hospital. Landing in Maryland from his native Nigeria at age 15, Fagboyegun found he had to repeat part of high ... Read More about When community is as important as the science: Olúmídé Fagboyegun
Humble cells in a little-known organ manage brain inflammation
Deep in the brain, sheets of tissue known as the choroid plexus produce cerebrospinal fluid (CSF) and act as a protective barrier between the brain and CSF. But the lab of Maria Lehtinen, PhD, at Boston Children’s Hospital has shown that the little-known choroid plexus does much more. For example, it secretes factors that promote ...

The gut-brain connection: A new approach to OCD and tic disorders?
It’s natural for young children to use routines to help them navigate the world and for older children and teens to zero in on interests and hobbies. But if they veer into disruptive, unwanted obsessions or thoughts or the need to perform compulsive rituals, they may have obsessive-compulsive disorder (OCD). We know that OCD is ...

Brain wiring predicted adolescents’ emotional health during COVID
The COVID-19 pandemic was emotionally devastating for many adolescents, disrupting their schooling and social/emotional development. Drawing on national data, a large study finds that how adolescents’ brains were wired — before COVID-19 — predicted their stress, negative emotions, and overall mental health during the height of the pandemic, making them more vulnerable or more resilient. ...

Exploring brain operations: Making decisions, snapping to attention, and forming memories
How do our brains snap to attention and orient us to the outside world — like when we’re sound asleep and the smoke alarm goes off? And when different choices confront us, how does our brain make decisions? Two groups of researchers at Boston Children’s explored these all-important brain operations. The first study, published February ... Read More about Exploring brain operations: Making decisions, snapping to attention, and forming memories
The journey to a treatment for hereditary spastic paraplegia
In 2016, Darius Ebrahimi-Fakhari, MD, PhD, a neurology fellow at Boston Children’s Hospital, met two little girls with spasticity and decreased muscle tone in their legs, which affected their walking. Both girls, Robbie Edwards and Molly Duffy, had been diagnosed with hereditary spastic paraplegia (HSP), a group of more than 80 genetic conditions. Untreated, the ...

When diagnosis is just the first step: The Brain Gene Registry
Through advances in genetic sequencing, many children with rare, unidentified neurodevelopmental disorders are finally having their mysteries solved. But are they? “Once families receive results of genetic testing, that’s just the beginning of a new journey,” says Maya Chopra, MBBS, FRACP, an investigator with the Rosamund Stone Zander Translational Neuroscience Center at Boston Children’s Hospital. ...

New leads for spinal cord injury: Mapping spinal-projecting neurons in the brain
Only a fraction of people who sustain a spinal cord injury fully regain their motor function. While rehabilitation can help, scientists have long looked for ways to regenerate injured nerve fibers — including, at Boston Children’s Hospital, Zhigang He, PhD, BM. As part of a collaborative effort by the BRAIN Initiative Cell Census Network, which ... Read More about New leads for spinal cord injury: Mapping spinal-projecting neurons in the brain
Lessons from Emma: Mom shares how RNS has changed their lives
Emma’s journey with the Epilepsy Center at Boston Children’s Hospital began three years ago when she came to Boston Children’s with her parents for help managing her seizures. In Boston, Emma, Lynda, and Danny found answers to their questions, a (temporary) new home, and hope for Emma’s future as she embarked on responsive neurostimulation (RNS) ...

Timing is everything: How circadian rhythms influence our brains
Why are we mentally sharper at certain times of day? A study led by Jonathan Lipton MD, PhD, at Boston Children’s Hospital spells out the relationship between circadian rhythms — the body’s natural day/night cycles — and the brain connections known as synapses. The work is the first to provide a cellular and molecular explanation ... Read More about Timing is everything: How circadian rhythms influence our brains
