According to the latest analysis in rats, a series of cerebral impulses that aid memory formation may regulate blood sugar levels. Scientists at New York University’s Grossman School of Medicine found that a peculiar signaling pattern in the hippocampus, which has previously been linked to learning and memory, also affects the metabolic rate, the procedure by which nutritional fats are transformed into sugar levels and provided to cells as just a power origin.
Brain Memory Signals And Blood Sugar Levels
The research focuses on the neuron, which are cerebral units that “fire” to transmit information. Researchers found in the latest days that populaces of hippocampal neurotransmitters fire in cycles within microseconds of one another, with the ability to fire sequence being dubbed a “sharp pulse ripple” because of the form it requires when caught visually by EEG, an advanced technology that registers brain function with diodes.
“Our study is the first to show how clusters of brain cell firing in the hippocampus may directly regulate metabolism,” says senior study author GyörgyBuzsáki, MD, Ph.D., the Biggs Professor in the Department of Neuroscience and Physiology at NYU Langone Health
“We are not saying that the hippocampus is the only player in this process, but that the brain may have a say in it through sharp-wave ripples,” says Buzsáki, also a faculty member in the Neuroscience Institute at NYU Langone.
With a regular rising number of patients suffering from blood sugar, this can be good news as such patients who go for medicines of blood sugar may have better memory and its related functions. Only they need to continue with the right medicine explained an expert who was an active member of the team that has carried out this research.
Insulin is a hormone produced by pancreatic cells that regulates plasma glucose by releasing it in bursts rather than continuously. The influence of sleeping disruption on acute waveform fluctuations may establish a mechanical connection among poor sleeping and elevated blood sugar concentrations shown in t2d, according to the research researchers.
“Evidence suggests that the brain evolved, for reasons of efficiency, to use the same signals to achieve two very different functions in terms of memory and hormonal regulation,” says corresponding study author David Tingley, Ph.D., a post-doctoral scholar in Buzsaki’s lab.
For its connections to different areas of the cerebral and due hippocampal synapses contain several surface proteins sensitive to hormones, they could modify their action as parts of feedbacks, the scientists believe the hippocampus is just a suitable contender brain area for many activities. According to the latest results, hippocampus waves are part of a cycle that lowers blood glucose.
“Animals could have first developed a system to control hormone release in rhythmic cycles, but then applied the same mechanism to memory when they later developed a more complex brain,” adds Tingley.
Short-duration waves that happened in groups of much more than 30 per second, as observed in NREM sleeping, caused a reduction in periphery blood glucose that was many times greater than solitary waves, according to this notion. The medial septum was silenced, which removed the effect of hippocampus fast waveform disturbances on periphery glucose.
The study group would continue to test their notion that overnight strong waveform disturbances can impact various hormones, as well as by working with human subjects. According to Buzsaki, further study may show gadgets or medicines that could modify waves to drop sugar levels & increase cognition.
