Disrupted connections between memory and appetite regulating brain circuits are directly proportional to body mass index (BMI), notably in patients who suffer from disordered or overeating that can lead to obesity, such as binge eating disorder (BED), according to new research. The research notes that individuals who are obese have impaired connections between the dorsolateral hippocampus (dlHPC) and the lateral hypothalamus (LH), which may impact their ability to control or regulate emotional responses when anticipating rewarding meals or treats.
Disrupted connections between memory and appetite regulating brain circuits are directly proportional to body mass index , notably in patients who suffer from disordered or overeating that can lead to obesity, such as binge eating disorder , according to new research from the Perelman School of Medicine at the University of Pennsylvania.
The dlHPC is located in the region of the brain that processes memory, and the LH is in the region of the brain that is responsible for keeping the body in a stable state, called homeostasis. Previous research has found an association with loss of function in the human hippocampus in individuals with obesity and related disordered eating, like BED.
In individuals with obesity, researchers found that the impairment of this hypothalamus-hippocampus circuit was directly proportional to their BMI. That is, in participants with a high BMI, the connection was even more disturbed.

Researchers demonstrate high-fidelity transmission of information via novel electronic-optical systemTransferring optical information in free space with large bandwidth and high transmission capacity has gained significant attention in various applications, such as remote sensing, underwater communication, and medical devices. Nevertheless, unpredictable, unknown phase perturbations or random diffusers within the optical path pose great challenges, limiting the high-fidelity transmission of optical data in free space. Adaptive optics presents a potential solution that can correct for random distortions dynamically; however, spatial light modulators and iterative feedback algorithms employed inevitably increase both cost and complexity.
