Upon eating, dopamine is released in the brain at two different times, during ingestion and when the food reaches our stomach, researchers report.
How well we are able to complete simple and complex tasks depends upon the organization of subnetworks in the brain, a new study reports.
DMT alters electrical activity in the brain. The compound significantly decreases alpha wave activity, the dominant rhythm associated with wakefulness, and increases theta waves, associated with dreaming. Overall brain activity becomes more chaotic and less predictable. The findings advance the understanding of the neurobiological underpinnings of immersive states of consciousness.
Following targeted motor and sensory reinnervation, a procedure that reroutes residual limb nerves to intact muscles and skin in amputees, the brain remaps both motor and sensory pathways. Additionally, researchers note, TMSR may help counteract poorly adapted cortical plasticity following amputation.
Researchers create a map of vision in the brain based upon an individual's brain structure, even for people who cannot see. Their result can, among other things, guide efforts to restore vision using a neural prosthesis that stimulates the surface of the brain.
A new study considers how thoughts take shape in the brain.
Using transcranial alternating current stimulation, researchers were able to influence the activity of specific brain areas and manipulate the abilities processed by them. Findings suggest tACS could be used to improve, direct, and attenuate the flow of information in the brain.
Acute inflammation of the anterior cerebellum resulted in depression-like symptoms in rodent models. Suppressing microglia helped reduce hyperexcitability and symptoms of depression.
Disruptions in brain networks emerge around the same time as chemical markers for Alzheimer's disease appear in spinal fluid, new research suggests.
Loneliness alters how the brain represents relationships, a new study reports.
Researchers release findings after using fNIRS to examine brain activation during a working memory task.
Stimulating the central lateral thalamus in monkeys under anesthesia was enough to wake the animals and elicit normal waking behaviors.
