For years,scientists have known that the human brain,unlike many other organs,retains the remarkable ability to generate new neurons even in adulthood. This process, known as neurogenesis, primarily occurs in specific brain regions, though at a significantly slower rate compared to early growth. However, the precise role these newly formed neurons play in cognitive function has remained a subject of ongoing debate and examination.
Previous research has suggested a link between reduced neurogenesis and neurological disorders such as epilepsy and Alzheimer’s disease. Individuals with these conditions appear to produce fewer new neurons compared to healthy individuals. But whether this decline in neurogenesis directly contributes to the cognitive impairments experienced by these patients has been unclear.
“We are part of a team of stem cell researchers, neuroscientists, neurologists, neurosurgeons, and neuropsychologists,” explains the research team. “Our newly published research sheds light on the connection between these new neurons and how we learn from listening to others.”
New Neurons and the Power of Listening
While studies in mice have demonstrated the role of new neurons in memory and learning, the technical challenges of identifying and analyzing these rare cells in the human brain have made it arduous to confirm their meaning in humans.
To address this, the researchers focused on patients with drug-resistant epilepsy who where undergoing surgical procedures to treat their seizures. These patients underwent cognitive assessments both before and after surgery, and donated brain tissue for analysis. By examining the tissue under a microscope, the researchers were able to identify markers of neurogenesis and determine the number of new neurons present.
“To see whether the number of new neurons a patient had was associated with specific cognitive functions, we looked under the microscope for markers of neurogenesis,” the team explains.
The results of the study revealed a engaging connection: patients with a higher number of new neurons in the hippocampus, a brain region crucial for learning and memory, demonstrated improved performance on cognitive tests that assessed their ability to learn from listening to others. This finding suggests that neurogenesis in adulthood may play a vital role in our capacity to acquire new knowledge and facts through social interaction.
This groundbreaking research opens up exciting new avenues for understanding the complexities of the human brain and the lifelong potential for learning and adaptation. Further investigation into the mechanisms underlying this link between neurogenesis and social learning could pave the way for novel therapeutic strategies to enhance cognitive function and address neurological disorders.
A groundbreaking new study has revealed a surprising link between the birth of new brain cells and improved cognitive function in adults, especially in the area of verbal learning.
The research,conducted by scientists at the University of Southern California,challenges previous assumptions about the role of these newborn neurons,known as neurogenesis. While studies in mice have shown a connection between neurogenesis and spatial learning, this new research suggests a diffrent function in humans.
“We found that new neurons in the adult brain are linked to reduced cognitive decline – particularly in verbal learning, or learning by listening to others,” said the lead researcher. “This was very surprising to us.”
The ability to learn and remember information through conversation is crucial for daily life, but this cognitive function naturally declines with age, and the effects can be more severe in individuals with neurological disorders. As the global population ages, the burden of cognitive decline on healthcare systems is expected to increase significantly.
“Our research suggests that the link between newborn neurons and verbal learning may be foundational to developing treatments to restore cognition in people,” the researcher explained.
The team is currently conducting a clinical trial to investigate whether boosting new neuron production through aerobic exercise can improve cognitive outcomes in epilepsy patients. “Current drugs for epilepsy primarily aim to reduce seizures, with limited focus on addressing the cognitive decline patients experience,” the researcher noted.
“We are currently in the early Phase 1 of the clinical trial, which seeks to establish the safety of the study. Thus far, two patients have successfully and safely finished the study. We plan to recruit eight more patients to exercise and complete this phase.”
This research highlights the importance of studying biological processes like neurogenesis directly in humans whenever possible.”Our finding that new neurons function differently in mice and in humans emphasizes the critical need to study biological functions like neurogenesis in people whenever possible. This will ensure that research conducted in animal models, such as mice, is relevant to people and can translate to the clinic,” the researcher concluded.
The findings offer a glimmer of hope for developing new strategies to combat cognitive decline and improve brain health throughout the lifespan.
New research reveals that adults continue to generate new brain cells, and these neurons play a crucial role in learning through auditory experiences. This groundbreaking discovery challenges the long-held belief that neurogenesis, the process of creating new neurons, ceases after childhood.
The study, conducted by a team of researchers at the University of Southern California, focused on the hippocampus, a brain region vital for learning and memory. Using advanced imaging techniques, the scientists tracked the development and integration of new neurons in adult mice.
“We found that these newborn neurons are particularly responsive to auditory information,” explained Dr. Aswathy Ammothumkandy, a postdoctoral research associate in stem cell biology and regenerative medicine at USC. “They exhibit heightened activity when exposed to novel sounds and play a key role in forming new auditory memories.”

The researchers believe that this discovery has critically important implications for understanding how adults learn and adapt throughout their lives. It suggests that engaging in activities that stimulate the auditory senses, such as listening to music or learning a new language, could promote the growth of new brain cells and enhance cognitive function.
“This research opens up exciting new avenues for exploring the potential of harnessing neurogenesis to improve learning and memory in adults,” said Dr. Charles Liu, Professor of Clinical Neurological Surgery at USC. “It highlights the remarkable plasticity of the adult brain and its capacity for lifelong learning.”

The findings,published in the journal Neuron,provide compelling evidence that the adult brain retains a remarkable ability to adapt and change. This discovery has the potential to revolutionize our understanding of learning and memory and pave the way for novel therapeutic strategies to address cognitive decline.
