Food provides the building blocks for our mental and physical health. New research reveals that many common foods supply key neurotransmitters that regulate brain and nervous system function. Understanding how our diet provides these crucial molecules opens up possibilities for supporting brain health through food. Key Facts: Foods contain the same neurotransmitters used by the …
Researchers have uncovered new insights into how fasting alters dopamine signaling in the brain’s reward circuitry. Their findings, published in the Journal of Neurophysiology, suggest that fasted mice exhibit enhanced dopamine release in the ventral tegmental area (VTA) of the brain compared to fed mice. This may help explain fasting’s impact on motivation and reward-seeking …
Medications are meant to treat medical conditions and improve health, but some can have the unintended consequence of weight gain, which can then worsen other health risks. Understanding which medications tend to cause weight gain and the mechanisms behind this effect can help patients and doctors make informed treatment decisions. Key Facts: Medications for diabetes, …
Insects are increasingly being recognized as a nutritious and eco-friendly alternative protein source that could help feed the world’s growing population. Recent research highlights the nutritional benefits of insects, their potential use as food ingredients, health-promoting bioactive compounds, impact of processing, barriers to adoption, and considerations around safety and regulation. Key Facts: Over 2,000 insect …
Emergency medicine doctors work in a fast-paced, high-stress environment filled with interruptions and competing demands on their attention. Research suggests that despite perceptions, true multitasking is limited in how it can be applied in this setting. The ability to efficiently switch between tasks is a critical skill for emergency physicians. Key Facts: Emergency doctors experience …
Researchers have gained new understanding of how the brain controls movement using both overt motor control and brain-machine interface (BMI) control. Their findings provide insight into the distinct neural processes involved in BMI control compared to natural movement. Key Facts: Rhesus monkeys were trained to control a cursor using either overt arm movements or a …
A new study conducted in rural South India has found that people whose parents are blood relatives (consanguineous marriage) have an increased risk of developing schizophrenia compared to the general population. Key Facts: Researchers recruited 120 patients with schizophrenia and 222 healthy controls from the same rural region in South India. 10.7% of patients with …
Electrical neural interfaces are unlocking new possibilities for studying, restoring, and augmenting brain functions. These devices provide direct communication pathways to connect the nervous system with the external world. Recent innovations in neural electrode design, electronics, wireless transmission, integration of electrical and optical modalities, and neural data processing are rapidly advancing the capabilities of electrical …
Research reveals that our perception of multitasking is often an illusion – most cognitive tasks cannot actually be done simultaneously. Surprisingly, this illusion of multitasking can improve performance on activities, even when the tasks remain unchanged. Key Facts: Although multitasking refers to doing multiple things concurrently, true multitasking is rare for cognitive tasks requiring attention. …
Focused ultrasound is emerging as a potentially revolutionary new tool for precisely stimulating the brain without surgery. This novel approach could transform how we diagnose and treat everything from depression and OCD to Alzheimer’s and stroke. Key Facts: Focused ultrasound uses precise sound waves to stimulate small regions deep in the brain without any incisions. …
