Researchers found that people with social anxiety have amplified brain activity that improves learning under low demands but hinders learning under higher demands. This sensitivity to the social context may be helpful when learning is easy, but becomes disadvantageous as demands increase.
Researchers found that theta oscillations during learning predicted which experiences were remembered after sleep, and this pattern was associated with better memory performance. The study suggests that the brain may use theta oscillations to 'tag' experiences for later memory consolidation during sleep.
Two studies found that mice take single sniffs to deliberately probe their environment, like humans. Humans process odors rapidly within a single sniff, mirroring rodent-like olfactory brain processing. These findings suggest fundamental biological rules behind smell processing have been preserved through evolution.
Researchers have identified a rapid physiological marker that predicts which patients with major depression will respond to magnetic brain stimulation therapy. Patients whose heart rates slowed within 45 seconds of starting treatment showed significantly greater improvement in depressive symptoms six weeks later.
A study found that memories acquired while awake are stored in a more permanent form during REM sleep, requiring the reactivation of only three adult-born neurons involved in memory formation. This process is synchronized with theta rhythm activity and essential for proper memory function.
Researchers found that the medial septum, a brain area in the center of the forebrain, plays a key role in encoding and retrieval processes. It helps generate gamma oscillations, which are faster for storing and slower for recalling memories.
Researchers discovered that synchronized neural oscillations in the right hemisphere of the brain induce empathic behavior in mice, allowing them to perceive and share each other's fear. The study identified the causal relationship between 5-7 Hz oscillations in the cingulo-amygdala circuit and empathic responses.
Researchers discovered a link between theta rhythm of the brain and gender differences in attitudes towards risk. The study found that men showed a higher risk appetite than women, with stronger frontal theta asymmetry and oscillations in the anterior cingulate cortex correlating with risk-taking behavior.
Researchers at UCLA discovered that virtual reality environments strengthen theta waves, a key brain rhythm for learning and memory, in rats. This finding could lead to new treatments for disorders like ADHD, Alzheimer's disease, and depression.
Researchers used a special backpack to monitor brain waves while participants walked around an empty room, finding hidden spots. The study found that brain waves flowed in a distinct pattern suggesting the brain mapped out physical space and boundaries.
Researchers investigate how 9-month-old babies process novel information using EEG. They find that the theta rhythm is sensitive to unexpected outcomes, suggesting it plays a key role in encoding new information. The study's findings have implications for understanding infant learning processes.
Researchers at Boston University found that electrostimulation can improve working memory in older adults by restoring neural pathways and synchronization. The technique also shows promise for younger individuals, as it enhanced memory performance even among those in their 20s.
A new study shows that deep-brain stimulation improves cognitive control by increasing low-frequency brain rhythms in the prefrontal cortex. This finding could lead to more effective treatment plans tailored to individual patients' needs.
Researchers studied theta rhythm and grid cell function to better understand navigation. They found that velocity modulation conveys critical information for grid cell signal generation, suggesting a new understanding of the brain's inner GPS.
Researchers at Boston University's Computational Neurophysiology Laboratory have discovered a link between theta rhythm and the ability of animals to track their location. Grid cells in the entorhinal cortex require theta oscillations as a clock to help animals keep track of their spatial location.
UCI researchers found that learning activates neuron receptors that promote brain growth and limit memory impairment associated with aging. The study suggests that staying mentally active as we age may keep neuronal BDNF signaling at a constant rate, limiting cognitive decline.
Researchers found that the septum can induce rhythmical electrical activity in the hippocampus, reducing epileptic seizures by 86-97 percent. The study suggests a new approach to stopping epilepsy, focusing on inducing theta rhythm generation.
