A team of researchers at Johns Hopkins University in Baltimore is delving into the intricate world of highly focused predatory birds, aiming to decipher the brain circuits governing attention.
Their primary objective is to shed light on the neurological underpinnings of attention-related disorders, including attention deficit hyperactivity disorder (ADHD).
"We believe we're on the brink of a breakthrough," stated Shreesh Mysore, an assistant professor who spearheads the Hopkins Owl Lab. According to Mysore, their findings suggest a pivotal role for an ancient brain region housing specialized cells that dictate what information to disregard.
Mysore elucidates his hypothesis from the confines of an owl room nestled in the basement lab. Amidst the cacophony of a restless bird perched on his forearm, he endeavors to elucidate their research. The owl squawks, flailing its talons, ensnaring Mysore's protected arms. Undeterred, he shields the bird's eyes, seeking to soothe the agitated creature.
The Owl Room at Johns Hopkins serves as a testament to the scientist's dedication, adorned with protective gear—a leather jacket, helmet, and gloves—essential for handling these formidable predators.
Owls serve as ideal subjects for Mysore's investigation due to their distinct behaviors. Their penchant for turning their heads to focus on stimuli facilitates the observation of attentional shifts. Moreover, their acute senses of hearing and sight enable precise targeting of prey.
As visitors to the Owl Room recede into silence, the owls resume their composure, allowing for focused research endeavors.
Mysore draws parallels between barn owls and humans, emphasizing shared mechanisms of attention regulation. He posits that the brain constantly evaluates stimuli to discern their significance, guiding subsequent behaviors.
The challenge lies in understanding how the brain filters out irrelevant information—a fundamental aspect of attentional control. Mysore asserts that addressing this question holds promise for individuals susceptible to distractions, encompassing not only ADHD but also conditions like autism, schizophrenia, and Parkinson's disease.
A significant hurdle in this quest is the limited understanding of the brain's mechanisms for suppressing interference. Mysore acknowledges the complexity of studying this phenomenon in the human brain but underscores the potential of owl brains as a viable alternative.
These avian predators possess traits conducive to neuroscientific inquiry, including fixed eyes necessitating head movements for visual scanning.
To elucidate the neural mechanisms underlying attention, Mysore's lab conducts experiments where owls must prioritize auditory or visual stimuli. These trials induce a competition within the midbrain, an evolutionarily ancient region found across species.
"When we present these stimuli, we measure activity in key midbrain areas to elucidate how neural circuits execute stimulus competition," explains Mysore.
A particular focus of Mysore's research is a subset of neurons within the midbrain responsible for suppressing distractions, offering insights into attentional control mechanisms.
In essence, the pursuit of understanding attentional mechanisms through owl brain research holds promise for addressing attention-related disorders, offering hope for improved interventions and treatments in the future.
Mysore's research endeavors extend beyond unraveling the mysteries of attention to exploring potential therapeutic interventions. By deciphering the intricate workings of the owl brain, his team aims to develop targeted strategies for mitigating attention-related disorders.
These insights may pave the way for innovative treatments tailored to individuals' unique neurological profiles, offering a glimmer of hope for those grappling with attentional challenges.
