Insulin signaling plays a role in regulating synaptic function, glucose homeostasis, and cognition, a new study reports. Impairments in insulin signaling result in metabolic defects, in addition to memory and learning deficits, mirroring the cognitive impairments associated with Alzheimer's disease.
Researchers at Boston Children's Hospital have developed a therapeutic cocktail of molecules that restored fine motor skills in mice with spinal cord injuries. When applied to mice who had experienced stroke symptoms, researchers observed increased axon sprouting in subcortical areas.
According to a new study, your sense of smell could be responsible for weight gain. Using mice, researchers noticed that those who lost their sense of smell also lost weight, while those mice with a super sense of smell gained more weight on a high fat diet than mice with a regular sense of smell. Findings suggest odor may play an important role in calorie burning processes; if you can't smell your food, you may burn it rather than store it.
Researchers have discovered a serotonin type 3 receptor activator that produces an antidepressant effect in mice and functions independently of SSRIs.
