Obesity isn't just bad for physical health. Being overweight can have a significant impact on neurological health too. Researchers identified a link between obesity and reduced brain plasticity. Brain plasticity impairment could lead to cognitive and learning deficits in those suffering from obesity.
Study identifies neurons in command of guiding adaptive behaviors.
Combining machine learning with neuroprosthetic technology allowed a patient with paralysis to learn to control a computer cursor by utilizing brain activity without extensive daily retraining.
Researchers have made an important discovery about the mechanisms behind learning and memory. Depending on the number of synapses, and their proximity, information is processed and stored differently.
Activity of the c-Fos gene begins the increase on the ninth day of exposure to antidepressants. By day 14, mice showed behavioral changes associated with SSRI use. This may explain why suicide rates drop after nine days of treatment, and symptoms of depression improve after three weeks.
Mitochondria regulate how neural stem cells become neurons during brain development. The findings may help explain how humans developed larger brains during evolution and how mitochondrial defects lead to some neurodevelopmental disorders.
Repeatedly administered tactile simulation over a sustained period of time alters neural processing of the hand area in the brain. The observable changes over time illustrate neuroplasticity and shed new light on the process of learning.
Oxytocin, the so-called "love hormone," could help to treat cognitive disorders, including Alzheimer's disease. Researchers demonstrated oxytocin reversed the effects of amyloid-beta on hippocampal LTP in mice. The findings suggest oxytocin could be used as a therapeutic for the treatment of Alzheimer's disease and other dementias.
Dropping the level of the IL-33 immune molecule increased the number of synapses in the brain. In older mice, ramping up IL-33 helped push the number of new synapses toward a more youthful state.
Neurons created as a result of adult neurogenesis mature for longer and grow larger than those created during infancy. Findings suggest adult-born neurons may have a more powerful function than those created during infancy and may play a critical role in neuroplasticity.
Study offers clues to how neurons can rewire and restore pathways following injury or illness.
Corticotropin-releasing factor and neuropeptide Y work in synchronized opposition to each other to remodel and rewire neurons in the amygdala as a response to stress. The process, researchers say, can be manually reversed to help relieve anxiety.
